The 3500-amp EGO brushless motor drives a second chainring. The rear derailleur creates an eleven-speed carbon fiber Moto that, um, can also be pedaled. The system adds about 15 pounds to the bike.
Kranked Electric makes expensive electric-assist power packs specifically for the Santa Cruz Tallboy LTc, Bronson, Nomad and V-10 models, and also offers a kit that can be retrofitted to many other models. Three power levels are offered, with different motors and battery packs, although Kranked anticipates that customers who can pop for the expense of the 2400-watt, 13 amp-hour, 40 volt, $2400 bargain kit, will probably opt for the moto-powerful, 3500-watt, 20 amp-hour, 60-volt Performance kit
(Santa Cruz bike not included). Kranked's kit includes the Lithium-Manganese battery, charger, CNC-machined aluminium motor mount, brushless motor and digital controller, special freewheeling crankset, handlebar twist-grip control and a two-stage drive that uses a planetary gearbox primary, and a chain-driven secondary system.

Kranked's 60-volt motor runs hot, so it uses a gel type cooling fluid that is assisted by fins on the housing. The controller box behind the motor and protected by a bash guard. The CNC'ed aluminum chassis is well executed and each is specifically designed to fit a Santa Cruz model.
Kranked Electric hails from Gibsons BC and is spearheaded by Bjorn Enga, who brought the bike to the Pinkbike pits to arrange for a future test ride at the Whistler bike park. Enga says that Kranked decided to forego the crank RPM sensor that prevents the motor from kicking in until the rider actually pedals the bike. Twist the right-hand grip and the Tallboy roosts - exactly as it should be. Output is around 2.5 horsepower and to put that into perspective, a top racer puts out about 2/3 of one HP on a climb, In watts, a Pro Tour sprinter can put out 1800 for a handful of seconds - the Performance EGO kit puts out 3500 for an hour or more. Range is about 20 mile and top speed is reported to be in excess of 45 miles per hour
(72kph).

The Performance kit includes a rather large battery, which is carried in a backpack to keep the bike's handling on the nimble side of the spectrum. Enga says that much of the cost of the kit is in the Lithium Manganese battery, which requires only 2.5 hours for a full charge. A large power cable, with a quick-disconnect plug connects the battery to the power controller. Kranked does the installation of the kit after your new Santa Cruz arrives at their factory.

I'm also curios what the land managers think. If you can ride this, can you ride a Zero motorcycle?
Sounds fun :/
Also, that thing is almost 8hp. That's like strapping 2 world-class sprinters to your bike.
I want one of these for commuting/going to work.
Where I come from every one throws the bike in the back of a pick up truck.
Europeans get it. E bikes are huge in Europe. Americans/Canadians are stupid.
Bjorn Enga gets it. He makes good movies too.
Gas engines are noisy and they stink.
However, there is a market for it. It opens the door for people that may not be able to ride bikes in the "fundamental" sense. Possibly a physical impediment or injury that doesn't allow pedaling.
How about the "green" perspective. Rather than shuttling and retrieval you just boogie up the hill and ride down. Or even people that are more interested in the dirtbike side of it that may be tired of burning gas to ride. Imagine the fun you could have on one these on the work commute!
Neat to see the tech just getting better and better for electric assist bikes.
Appreciate it for what it is be it for you or not.
Also a bike for da fatties
Tallboy LTc - $6000
Kranked Kit - $2400
Total: $8400
OR
2014 Yamaha YZ450F - $8500
As much as I love mtn bikes and riding, I would drop that kind of cash on the YZ - it's a god damn top shelf moto bike.
Why not just buy a motor bike? Why even bother with pedals. Is that just a legal loop hole so we can destroy all the MTB specific trails with a high torque electric motor? This is ridiculous and needs to be stopped.
Still, some displaced dirt is laughable as a form of "environmental destruction".
You DID read the article and know that you DO have to pedal the bike still...right? So, you're still going to get the same amount of exercise if you stay on the bike the same amount of time.
Also.....if all you ride is mountain bikes, I guarantee you are not fit enough for a dirt bike competition of any kind. MX, desert, GP, whatever. Competitive MX/desert is the most physically demanding sport in the world. Polar opposite of NASCAR.
The tech in batteries is pretty bad for the earth, but are you on a laptop or smart phone? Same tech. Fortunately Toyota is introducing new technology that will make lithium unnecessary: the super capacitor the use in their new experimental hybrids is clean and efficient.
They are marketing this to the wrong crowd. They should advertise it to motorcyclists. That is no big sin. Get over it.
People want motors to GO FARTHER. When is the last time you put in 120 miles of singletrack in a single day? I'm guessing never.
If some braking ruts really piss in your wheaties, you should probably just get a road bike.
How can adding a motor to a bike be a step backwards, motorbikes already exist and have done for quite some time. How can this negatively impact the sport? Fast as shit kids who race will never use this they are the future of the sport how will this "slow them down"
Actually think that's a very cool thing for FR/DH purpose if You could get easly on the mountain that has no lifts, no access for shuttle service. Still bit cheaper than heli ;]
Like the idea, and new possibilities. But than again, really wouldn't want to see mountains crushed by loads of people on fancy electric mountain bikes.
We pedal a lot and it used to be that when the legs were tired we went for a trials moto ride ..now when the legs are tired we hop on the ebike and go for a mellow trail ride....Its way better then setting up shuttle vehicles (which is another practice we used to do...and as I do pedal along I still get a nice spin in as we get to the top.
They are not for everyone, but that doesn't mean they are for no-one...and I'm 100% certain that once you take it for a 2 hour spin you will not want to give it back.....Note that the first 10-15 min may be a bit terrifying as the torque is tremendous...and I am used to a 250 2stroke trials moto....
If you are in Whistler this summer, and after two days of hammering the park your body needs a brake, but mentally you still wanna ride... you should go for a trail ride with Bjorn - you wont regret it
I personally love riding my bike. It is not a motorbike experience but a riding experience. I love this technology because my reality is I am riding my bike more than I ever have. In fact when not trying to tell Richard all the facts about the bike, which he mostly got wrong anyways! I was riding the incredible trail network in the back of Leguna Seca. I rode 160 km in 3 days of Sea Otter. I did not 1) cause any trail damage 2) cause any trail conflict. 3) ride recklessly. 4) get fat or feel lazy. In fact I am exhausted from riding so much and am in great riding shape because of this technology.
I would just like to say that as riders we all want the bike and gear that let's us ride further, faster. In fact the whole Sea Otter expo is dedicated to this premise. This electric technology allows you to ride, further faster. It is truly amazing. I look forward to hopefully watching the positive aspects of this technology be embraced and enjoyed by some of you passionate pink bike shredders! Ride hard, ride free.
Is your SC Warranty voided once installed?
There's no darn way that this bike (or any SC bike) was designed to have a electric motor attached to it to assist in pedaling. Although, this gadget may be useful for those that have physical disabilities in their legs (from accident or born with it) and need that little boost.

For one who has experience on e-mtb, the feeling you get is similar to that of a lighter bike. If you think you're going to be able to shuttle yourself without pedaling, you're dead wrong... dead battery wrong. You might be able to shuttle at a speed similar to walking a few times before you deplete your battery, but you're better off riding it like a normal bike and using the throttle to "flatten the hills" so to speak.
Anyhow, please stop comparing e-mtb to gas-powered dirt bikes. That's like comparing a golf cart to a Baja rally truck.
Also I like witnessing these "e-bikes" riding in areas they shouldn't be...
Also, I quite often detach the cord for the sustained descent, I can easily pedal the bike across flats and small ups....I mainly use the motor for the long fireroad climbs
Chaos, broken clavicles, and search & rescue ensues...
I see the two sports getting more and more similar, with motorbikes getting to be more like MTB instead of the other way around. A light motorbike could use DH parts (easton 35mm bars) and soon we would see it as another genre of riding: xc, am, enduro, dh, and MX.
I look forward to MX resources being added to MTB r&d, bringing us better gear.
So stop crying about this and realize it isn't taking over, just expanding the options.
But in the end, if you really want the assist of electric and have $8-10k to drop, just get the license and insurance and buy a nice crossover bike for road/trail riding.
These make sense in comuter bikes, but not in hard mountain bikes.
Carbon zero and quiet unlike a gas bike, and u can lift it over a fence. All that pushing and first gear riding I see doesn't look fun to me, I've never been silly enough to try it, a hot chick would be better exercise if that's the excuse. Furthermore, an e-bike is hardcore exercise if you're riding hard. I don't see fat e-bikers at the top of my favorite track, actually I don't see any other bikes as they can't make it up - too steep for peddlers and too tight n gnarly for gas bikes. Thing I like the most is passing hotshot riders on their flashy new mtb bikes around the corners as they can't get their piddly power down without clipping pedals. Love passing them in the air while they stay glued to the track going too slow but I have to be careful not to land on them. And it's heaps cheaper than my mx gas bikes to run.
Any e-bike disser in NZ want a race for money? Uphill, flat, technical. Bring it on!!!
Since when did Mtn bikers start riding chair lifts ?That’s retarded.And the Dekine pad truck dropping is even worse.
Perhaps it could be regulated with some kind of payment or health excemt to ride marked trail.?
They are coming and everybody is going to get old ?!!!!
Its a tipical american thing....way overdone!
On the other hand I'm not sold on this particular e-bike. I would prefer something more integrated and I would hate to cary a battery on my backpack. Anyway at the moment I'm pretty happy pedaling my bike without any assistance. In 30 years... who knows.
you'd get so much more to repaire
you'd get unfit
it takes away the point of biking
IMO- santa cruz's are horrible (nothing to do with the motor)
what is the point?
and it'll cost a bomb...
the only good thing i could say about this is that it'd get you up hills (made of ROAD...) other wise i'm perfectly happy with pedalling, thank you very much
great engineering
work metrolink 40C3 40lb ebike goes 40mph+ range of 40 miles speed in closed caption (cc)
This is new ultra light ebike weighs 40lb and goes 40mph with a range of 40 miles.
i dont like recreational bikers who lug their bikes around on 4000 lb suvs and then whine about me using electric assist.
Well I do and will rub anyones nose in the dirt who wants o keep up with me
