First Ride: Bosch Performance Line CX Race Limited Edition Motor

Sep 28, 2022
by Ralf Hauser  



Just before the final EWS-E race in Finale Ligure, Bosch seized the opportunity and officially presented their limited Bosch Performance Line CX Race motor to the press in sunny Italian weather. Not only did we get an opportunity for a first glance of the new CX Race version but were able to take it out for a spin, before mechanics got busy swapping out a bunch of EWS-E racers' motors for the new model ahead of rolling to the start line.

Bosch's commitment to e-bike racing has been a factor since the early beginnings of the e-bike racing movement. Apart from having sponsored and supported many teams and individual athletes in EWS-E-races and other e-bike racing series, they've played an active role in establishing framework conditions for professional e-bike races together with the UCI. Apart from that, Bosch is also campaigning for clean racing, with uniform regulations and active action against tuning.

Therefore, it shouldn't come as a real surprise that Bosch's development team has been working on a race-specific version of the Performance Line CX motor in close cooperation with athletes such as Jérôme Clementz, Tracy Moseley, Joris Ryf and other active racers who, among other things, provided direct feedback on various developments and setups at the annual Bosch development camp or directly at various races. The result is the Bosch Performance Line CX Race Limited Edition and while many elements of the CX Race hardware are very similar or identical to that of the normal CX motor, it's the new additional Race ride mode setup that cranks the performance of the CX series up to eleven.

The new Bosch Performance Line CX Race Limited Edition

Motor & Software Details


While the magnesium housing and the structure of the motor itself have remained the same, the clearest visual distinctions are the particularly resistant graphite-grey metal finish and of course the logo badge. 150g of weight has been saved on the innards, bringing the CX Race motor down to a total weight of 2.75kg, although Bosch is quite tight-lipped on how exactly they achieved those weight savings.

While most base numbers like 85 Nm of torque remain the same, the Race mode will provide up to 400 % of rider input instead of the conventional 340 %. The Extended Boost feature has also been integrated into the Race mode (so far was only integrated into the eMTB mode), and the overrun time has also been extended to make it even easier to overcome particularly large obstacles.

Viewed as an overall package, the race setup ensures a more energetic response and faster delivery of maximum power in order to save valuable tenths of a second again and again on the trail, especially in situations such as accelerating out of corners. With races often being decided by small time differences it can make the difference between standing on the top of the podium or just a few steps below. Along with more constant thrust throughout challenging terrain provided by Extended Boost, when only being able to deliver short bursts of pedalling input, the rider basically benefits from the Race setup in all technically demanding sections.

Despite exhausting the technical possibilities, it was important for Bosch to mention that the CX Race version operates within all technical regulations and does not break any rules of the maximum permitted country-specific regulations.

In terms of software, all conventional riding modes from the conventional Performance Line setup are still available, but on top of that, the Race mode – with red color coding – can be selected as an extra option. This mode can also be fine-tuned in its strength of support, dynamic range in plus/minus five levels, maximum speed and maximum torque, using the Bosch eBike Flow app that can connect to the bike via Bluetooth.

Labelling the CX Race as a Limited Edition model isn't just marketing talk. Bosch works closely with bike manufacturers to ensure that the CX Race Limited Edition package is only available in certain quantities to each manufacturer and installed on bikes that technically provide a fitting platform for the product, meeting certain requirements for making a bike suitable for racing, or racing-like applications.

At least for now, Bosch clearly sees their Race adaptation as a special use case application for the racer type of rider and doesn't see the average biker as a target group for the added feature, as they might be overwhelmed by the sensitivity of the settings.







We didn't get a whole lot of time to get in a first ride with the Bosch Performance Line CX Race Limited Edition setup, but fortunately, Finale Ligure provides ingenious testing grounds even within a small area, which can usually only be replicated elsewhere, if at all, under a much greater investment of time.

Apart from that, it is pretty easy to notice the differences between the regular ride modes' behaviours and the Race mode anyway. With every acceleration, the motor pushes quite effortlessly and instantly, to reach its maximum power faster than what could be achieved in Turbo or any of the other modes. It's not as if you'd be sitting on an entirely new product, but it provides a nice punch to Bosch's CX repertoire. Naturally, this becomes particularly helpful when accelerating out of corners or when trying to climb towards the top speed in uphill sections as quickly as possible.

However, in my opinion, it feels like most riders of different skill levels should – at least in theory – not feel too overwhelmed by the extra power delivery. Bosch has by now skillfully mastered the control of the power delivery of its motors to the point that you don't have to worry about the rear wheel spinning wildly even when starting on loose ground (unless you force it to), or that any sort of pedal input would end in uncontrolled forward movement.

In combination with the slightly longer-lasting Extended Boost function, the system can especially play out its full strength when having to navigate sections plastered with bigger rocks or roots with delayed pedal strokes, or when having to overcome boulder-sized obstacles, in order to be able to maintain the rolling speed relatively easily.

In general, the Race mode is also beneficial in case you did not select the matching gear for any given situation or if an unexpected steep section is waiting for you behind a blind corner. It's just a shame that the CX Race motor also rattles like the regular version when idling.

After playing with the Bosch eBike Flow app a bit and varying the dynamics setting of the Race mode from -5 to +5, the behaviour changes in fine steps, adding another noticeable variation of the mode independently of the strength of support, which can also be adjusted. Assuming a standard setting of 0, the reduction has a stronger effect than an increase – as intended by Bosch, since the standard setting of the Race mode already allows for a fairly rapid increase in power.

A quick detour led me to Finale's 'Impossible Climb' – as the locals sometimes affectionately call the e-bike uphill trail Legnino – as it offers quite unique challenging conditions to evaluate extreme climbing capabilities for any kind of motor system. Although line choice seemed to have been widened and made easier with extra options for the last EWS-E event of the season, the original routing over trial-like sections inevitably showed how capable the Race mode was under said conditions. Massive power and yet smooth modulation were a guarantee for maximum traction and forward drive up the rocks. In this respect, too, the new setup deserves top marks.

Personally, only the thought of the limited availability might be a cause for concern. Even if it is not yet clear what price tags will be attached to bike models with the CX Race motor, it can be assumed that you will probably have to dig deep into your pockets to get to enjoy the new Race mode. Racers or not – and let's be honest, it's clear that at least for now the number of non-competing e-bikers still far outnumbers that of active e-bike racers – the Race riding mode is without a doubt a valuable addition to the modes already available on the regular Performance Line CX model. Once you experience the difference, it will most likely be missed on models with the standard CX variant. Time will tell whether only experienced riders will be able to experience both.

 Imagine if you didn’t have to compromise with the low energy density of batteries, but could put some sort of high energy liquid in there, which then could be utilized in an explosive manner.
You could then ride a much more powerful motorized bike on trails.
Which means you could ride even MORE trails in the same time frame, compared to an e-MTB.

 All these different super powerful race modes, is there any point to them if the motor is regulated to 15 mph as in uk?

 @jimoxbox: before Brexit you probably adopted EU regulations - 25kmh as a limit for motor assistance. So every second person pay for some hacks to rise it to 45kmh usually. Then its maybe because scooters and small motorcycles manufacturers would be bitching about that there's no driving license needed for e-bikes and also many of their users are non-sporty people who really can't handle it well enough.
  • 4 2
 @jimoxbox: Was going to say exactly the same thing - On faster trails where there is a lot of pedaling out of corners the 15mph limit is a real shitter, I suppose the point here is to make the bike faster for the uphill parts of race stages.

For my own personal e-bike use I will be heading towards a lower powered, much lighter bike as it suits my riding better that is essentially a fire-road climb and techy, sub 15mph descent on the way down.

 And this is why on an ebike you get to use the cheapest all steel drivetrains and save money when replacing parts. You do need to have a top line chain though. Replace XX1 $500, NX $100

  • 3 2
 @Dlakusta: Lol, no. It's a balance. Replace X01 after 6-10k miles on a regular bike, replace NX after like 1k miles. Same reason you see people running X01 cassettes over GX or lower, because those setups die a death way too fast and end up costing you more than if you had just bought the nicer cassette.

 @nickfranko: It's not the cassettes, it's the chains, really. GX and lower chains lack the hardening treatments that actually matter, and wear so unexpectedly fast that you can cook a chain _and_ cassette without even realizing it. A GX or NX cassette with an XO1 chain will last a good long while it'll just be quite heavier.

My GX cassette has gone 500 miles on a GX chain (that was pretty toasted after those 500), and then 1500 more miles on an XO1 chain, and that XO1 chain is just now starting to get to where I'll think about ordering another, while the cassette is still looking and feeling quite decent, likely enough to do another 2K miles with a good chain.

 @DizzyNinja: The point is this already exists:

kindernay.com/product/product-landing-kindernay-vii

Pinion, the 14 speed Kindernay, Rolloff, etc, all use multi-stage gearboxes. If you reduce the range to under 450% then you can have single stage gearboxes, making them cheaper/simpler/lighter/stronger, all the things gearboxes need to be practical vs derailleurs.

Those with the technical knowledge know that it's not actually stretching anything, but the external effect is that the chain seems to have stretched. You just want to be able to correct people who don't have the same knowledge of technical details. I'm sure their are a billion technical details about computer and software engineering that you gloss over with vernacular terms every day, that I could easily dismiss as technically incorrect. That doesn't make your daily informal usage of those terms completely incorrect. Abstractions and approximations are everywhere, especially in living languages. That's also a fact.

 Could we mention how Bosh is a terrible company not caring for its users? it's a closed system, Bosh does not allow anybody to fix, or maintain their products and you can't buy a motor. I had a bosh motor dying on me with a software error ( on a used Trek), the battery was fine, the motor was fine, but Bosh was not able to fix it, they could only offer to replace the whole system ( even thru the battery and computer was diagnosed as OK, The Trek stores also offer to dispose a 7k bike and replace it with a new one with a whopping 15% off.
I won't mention how long the process has been.
I ended up buying a new motor on the grey market from another continent (which is not technically allowed by bosh) for a few hundred $ and got back on the trail happy instead of spending thousands and generating tons of waste.
I would like a company to produce a motor I can easily replace and maintain and maybe an open-source firmware I can tune to my liking.
The current motor manufacturers have a terrible business model for us riders, their customers are bike manufacturers so their motivation is to sell more bikes not to provide a good experience to the end users
  • 10 2
 I guess that's why a lot of manufacturers are going with Shimano?
  • 16 6
 The reason the Bosch (insert pretty much every single ebike MFG) system is so controlled is due to legal liabilities. If you give your end users the possibility to tweak your firmware/engine, you're also opening yourself up to potential lawsuits for allowing them to circumvent laws regulating ebikes.

 I'm glad my comments got some good feedback, I would love for pink bike and other media to question a bit more the whole e-bike product cycle instead of just relaying their marketing. Ebike has a really questionable life cycle and their value is close to zero as soon as the warranty expires. It's maybe the norm for some industries but definitely not bikes. I can totally service and find spare parts for 30 years old MTB (or cars or motorcycle) but if I buy a 10k+ ebike today, I have no warranty I won't have a useless piece of equipment in 5 or 10 years..
So far all these manufacturers are totally irresponsible and have no plan to support realistically their product in the 5 or 10 years.
(I say realistic because offering overpriced repair more expensive than buying a new product like Apple does is not a reasonable approach)
I'd like to see e-bike tests to feature longevity and support and so far it would be 100% for most traditional mtb kitted with standard components and 0% for most ebike.
As a comparison, I'm building electric skateboards and I can totally pick the battery, BMS, ECS, and brushless motors of my liking and there is even open source firmware that let me tune the quality ride I want.

As a german company producing a product for the outdoor segment, I would expect a greener approach.

 @OneTrustMan: It's not just e-bikes that are being obsolete so fast. Basically, the whole bike industry has become that way because it's become like the clothing industry. It's the masses that buy into the marketing shit. It's a perpetual cycle to get people wanting to buy the latest stuff because, you know by next year, your current stuff will be considered outdated. E-bikes, along with the whole biking industry, has become the wild wild west. Everyone wants to get in and cash in. The motto for the last 10-15+ years is "who gives a shit about what you have last year, I need to get the latest and greatest!" Consuming and environment are basically an oxymoron - there's no better way to show this contradiction, Only marketing will show you how GREEN everything is.

 @greenblur: LOL, it's more like gun manufacturers are protected by the gun lobbyists and by the politicians that pocket the money from the lobbying group. The Second Amendment to the US Constitution only states the right to keep and bear arms in the United States. This has nothing to do with protecting the rights of any citizen of the US or anywhere in the word to sue these arms manufacturing companies from wrong doing. In fact, Remington and Winchester got sued some time ago when some of their firearms were faulty. You can also sue a person for misuse of a firearm for causing harm to you or anyone else. Plus, the 2nd Amendment was put in place for the militia of a free state. This would only makes sense for military/police or for hunting/sporting/survival situations. I think the average American takes that Amendment way out of context.

 max2max, I could not agree with you more. Specialized has the same problem as Bosh. I Have a 2019 Turbo Kenevo with 1,100 miles and it shredded the belt. Up to this point everything was working fine. Guess what? Local bike shops do not sell parts (belt and tensioner) and they do not work on them. Was told they just swap them out when under warranty. BUT, since mine was out of warranty I got to pay $999 US for a completely new motor! Imagine paying 15K for the latest and greatest bike (name your brand) bike and after 2 years your now out of warranty motor fails.....you get to pay $1,000 for a new motor or your sweet bike is now a paper weight. A little searching the web you can locate some aftermarket parts for some of these motors, but even then it will cost you $150 for a tiny little belt and tensioner.

Even the various trails 15 or so miles away were still a go, just didn't intentionally meet up with anyone for those first couple months.

 I feel like e-bike racing should be at the absolute extremes of MTB racing. Like moto style hill climbs thats barely rideable then a rampage run on the way down. Otherwise, what's the point?

 I kind of agree about the uphill part, but why would the way down be any different - are e-bikes magical at descending too?

 It can be. But if the demand for other e-bike racing disciplines are popular, then they will also be options.

 Ebike racing should be designed around the best use case for ebikes, which is self shuttling. I.e, enduro stages on the way down, access or light trails on the way up, both timed. That way manufacturers would actually be forced to figure out how to optimize the ebikes for that, instead of trying to create a pointless super light ebike.

 Good luck making it fair for all e-race competitors. The obscure "max 250 nominally" regulation means nothng when manufactures keep making "clever" designs to increase power in "exdtended boost" without violating the rules.

 I hear this argument all the time. All sportes have rules and regulations. Competitors will always try to find ways around it to make it their benefit. Bending the rules are a part of the game.
  • 17 1
 I'd really value a dumbed-down article here on PB explaining the whole concept of e-bike racing. Making super powerful and fast motors is already possible, so you'd say that in racing everything is just limited to the far edge of the regulations by software settings. If one company comes with a new version that exceeds one or more of the software limits of the regular version, why wasn't the regular version already tuned to this very limit? And if it were fair, why is the version with extended limits only available in limited quantities and on limited bike models, hence won't be available to all competitors (especially privateers)?

Maybe this is super cool and all, but to me it is on the same level of "our engineers worked super hard and really thought outside the box and now managed to add another tooth to the largest sprocket of the cassette".
  • 5 2
 I don´t get that as well. All eMTBs deliver more than 250Watts at some point. So whats the point of this regulation. Now a stronger Motor with more boost, for an extended time period is able to save "tenths of seconds" - no shit.
But I don´t get the concept of ebike racing to begin with.
To me it has nothing to do with the heart of racing - competition.
It´s just a marketing thing.
  • 5 3
 @vinay: the concept of e-bike racing is - it´s cheap marketing. 30 men and 4 girls in EEWS costs way less budget than a deep field of well in to the hundreths competitors in EWS.
I don´t know why Chris Ball and the EWS let them onboard. I guess sponsor money is hard to come by, so they´ll take whatever they get. But they should leave it a hobby-category.
  • 7 1
 @styriabeef: I agree with everything except the part about why race ebikes... Racing is racing, The first bike race was the day the second bike was built, same with all modes of transport. The motor only helps propel the bike, the rider still is in command. Just like any motorsport. Do I think ebike racing is comparable to MTB or any other cycling discipline? No, because of the motor. Is it still a competition? yes. Should it be UCI regulated? Who cares, the UCI sucks.

 @BikesBoatsNJeeps: "Just like any motorsport"

That's just it, ebike racing is a "motor sport", not mountain biking. The old adage that "it's the rider not the bike", just doesn't apply when some riders simply have more motor. It 's the bike at least as much as the rider, if not more with FOUR HUNDRED PERCENT BOOST.

  • 1 0
 @danger13: For me it isn't so much about cheating. If they all engage in the same game and adhere to the same rules, it all seems fair to me. I'm just curious what the actual rules are considering what I said in my initial post. What I gather from this discussion is that there is a 250W output limit but it is ok to exceed that for a short while. So how short is short and how far can you exceed that limit? I'm still confused.
  • 1 1
 @vinay: the answer to those last confusing questions seem to be, at least right now, whatever Bosch has in their latest tune. They say they're going to lobby for limitations, but if Shimano or brose or whoever finds a tweak to get a little more overboost without immediately exploding the motor, they'll be lobbying hard for _their_ limit to be the new limit. We'll need the FIA or IMSA instead of UCI, because, again, it's a motorsport.
  • 1 0
 @justinfoil: Oh, that sucks actually. I trust that once a new rule has been accepted, it will take a few seasons before it comes into effect in order to give competing brands a chance to catch up. The ones who are being screwed are the privateers who need to replace an otherwise good motor, just to keep up with the rat-race. And unlike suspension and gearing, the motor is sealed so there is no way for an amateur to update it themselves.

Just curious though, isn't there a limit in the amount of energy (so battery charge) you can take with you? If so, at least it would be fair in a way that you should use your energy wisely. I competed in the World Solar Challenge back in 2005, which is a solar car race from Darwin to Adelaide. You start with full batteries in Darwin and from then on you have to balance it with the amount of solar energy you collect. The size of the car was limited but there was no limit to the area of solar array nor to the aerodynamics. So maxed out the solar array area and made the car pretty low, but eventually went so fast that in Southern Australia (where unlike in Northern Territory there is a speed limit) no one could overtake us anymore. Closest competitors were fairly quick too, but with all of us riding at the speed limit there no longer was a competition. In subsequent years, the organisation introduced more and more strict rules to make the cars slower again and that's what brought some competition back to it. So I think that instead of making these motors faster and all, it would be most exciting to at least limit the battery capacity to a point where you really need to be careful how you use it. So careful that it would actually be worth it to bring a lighter motor to save weight. Not saying it should mimic a typical XC race but yeah, use the boost only where you think it could really help you but then back off elsewhere.
  • 1 0
 @vinay: I don't know if people even use a whole battery in a race... but that could be a good limiting factor. Similar to class-specific fuel tank size and KERS capacity in endurance motor racing. Limit everyone to a 300 Wh (or less!) battery, force them to be smart about modes and when to use the boost.

Side note, I'm not from Australia, so my conceptions might be completely wrong, but I kind of find it funny that there is a speed limit for the race in the Northern Territories but not in SA. Isn't it basically just desert and national parks between Darwin and Alice Springs? Joking, of course, but kinda not. There are less people in NT than all of Tassie!
  • 2 0
 @justinfoil: The solar car race is on public roads so you've got to obey the traffic rules. Indeed it is pretty much all desert along the Stuart Highway. Because it is a two way road even in Southern Australia we were allowed to exceed the speed limit when overtaking (to be done with it quickly). So that's what we did, we overtook loads Wink . The area around beautiful Katherine is no desert but pretty hilly and the road has some interesting turns. Which scared our observer shitless as our car was using adaptive cruise control tuned to be most efficient. Which in hilly terrain implies, keep power steady. So that was slow climbing and fast descending, no matter whether the road is straight or curved. Not sure how well known the race is in the US. There were two US teams competing back then, maybe more that I didn't know of. MIT broke a wheel during the qualifications at the Hidden Valley race track and crashed. We actually helped them retrieve their solar array as their truck was way to big to enter the track and we just had a small flatbed trailer behind a pickup truck Wink . They still impressively finished sixth at the race if I recall correctly. Michigan finished third.

As for the e-bike race battery, yes by all means make it so small that riders really have to be strategic in how and where they use it. Just having an abundance of energy on board takes away a big part of the challenge. Even in F1 car racing they have to be strategic so that they may be able to finish the race with one fewer pit stop.
  • 1 0
 @vinay: I've heard of the race, but didn't know details. pretty cool.

F1 takes it a step further and limits the places you can use certain boosts. DRS isn't the same as a KERS or such, but the effect is similar to a power boost and I know there are specific zones for DRS usage, and I think they might also apply if any team did use the optional KERS. E-bike racing needs to go full motorsport and set some explicitly defined formulas/classifications, and definitely apply total energy limits along with instantaneous power limits.

And I think ban any kind of overrun extended boost bullshit. If being "pedal-assist" is the thing that differentiates e-bikes from being simply motorbikes, then it needs to be a real (dumb) pedal-assist, not "pedal-controlled" bullshit that keeps applying power after pedaling. They like to market pedal-assist as "you but faster", but if the system can make any power when you're not making power, then it's not pedal-assist anymore.
  • 3 0
 @justinfoil: Agreed, never heard of this overrun thing in the first place but it sucks. I can imagine it was a challenge to make a motor that responds proportionally to pedal input so there would always be some lag both in engagement as well as disengagement. But to consciously extend the time before disengagement seems very wrong to me. Not necessarily from a competition point of view because I don't even care that much. But I do care for the condition of my trails. Just like with powerful brakes, I do believe a skilled rider can modulate such that they'll only demand traction when they can. But if they're going to extend the overrun time they'll consciously sabotage their ability to gracefully make it up there. Not just the racers (who don't seem to care much about trail preservation in the first place) but also the enthusiasts once this "technology" trickles down. I'm not one to be very anti-e per se, but I do disapprove of unsustainable decisions made here.

It’s fun, loads of fun. And regardless of the motor, it still takes talent and skill to do it well. How well can you do it vs your peers? Race and find out! Also, I’ve not seen this many complaining whiners in one place! Seriously, have some f*cking fun in life and stop complaining about everything! Whining about everything from ebikes to a company making the product, (motor) better and faster! That’s the object of any competition, to make it the best and fastest available! That’s also a competition between manufacturers, to have the best product! And yes, they do it to sell more product and make more money, and I’m ok with that if I can have a better product.

  • 1 0
 @Twenty6ers4life: Timed tech climbs are the best solution for making an e-bike race a real competition. I see tons of opportunity there.

Who can sprint the fastest out of a corner with e-assist isnt really a race though. You can tell whos gonna win that by looking at the motor specs, no stopwatches need to be involved. So again as a serious sport, about as much good as an egg and spoon race.

Tech climbing though, they're onto something there. That is a true test of both bike and rider.

 @danger13: I think that's my whole drift about the e-bike is that rather than neglect your health or your love to be active, the assist motor helps you enjoy what you were doing before. What you're saying, like most nay-sayers about e-bike, is that it's 100% like a motorcycle where one doesn't do any pedaling. That's a 100% fallacy because, like I purposely stated, the motor is there to assist when you pedal. The motor stops assisting when using brakes or during downhill. So, skill, upper body and leg strength are still needed in technical sections for mountain biking. It's not like you're totally a vegetable or a couch potato sitting on the bike and it does everything for you. I do watch some youtube videos of my friends biking through the woods, but I'd rather bike through those singletracks myself whether it is a e-MTB or a non-assisted bike. You can say the same thing about people shuttling up or taking the ski lifts just to come down the mountain on their mountain bikes.

There are zero, I repeat, zero! need to constantly watch a display while riding. This is mtb-ing, not roadies stuff. Stop kidding yourself or try to BS-ing others into this nonsense. In the second in which it is more important what it is written on a screen then what the f you are doing with the bike on the trail, you might as well stop mtb-ing at all.

  • 2 0
 You should do a little research before you comment in a public forum about something you obviously know nothing about. The motor still has the same peak power of 85nm as the standard motor and the same top speed limit. It’s also 150g lighter than the standard motor. It’s just programmed to get up to full speed quicker and to accelerate faster out of turns. If you were a manufacturer, would you want to give your racers a slower motor with a slow power delivery? No, you would quickly go out of business. What wins on Sunday, sells on Monday.
  • 1 0
 I think it should be noted that the overrun comes into conflicts with some United States laws on pedal assist, I would consider race mode to be not a class 1 designation anymore then. I worried Bosch would do this with the last software and it was subtle enough to really work good with the boost but now I wonder if it’s beyond the legal latency for acceleration forces and could be construed as a pedal operated throttle. Just saw some guy ratchet the cranks around on a Pole at 15 mph in the dirt, if that’s not beyond realistic. Also this mode is going to get inexperienced riders severely injured or killed.

 I watched several videos on youtube about this motor last night and the thing that stuck out to me the most is the built in overrun. I have a gen 3 levo in the shop getting a new motor right now because it started having this happen with about 700 miles on the motor. Basically when you stop pedaling the motor continues to pull for a second or 2. In my case, it was intermittent so you had to always be ready in case it happened and it almost caused a couple of wrecks.
