by Rocky Mountain  

PRESS RELEASE: Rocky Mountain Bicycles


The Overtimepack allows you to ride your Powerplay farther than ever before, putting more time in on the trail before needing a charge.

The Overtimepack is a range extender for our Powerplay lineup that offers an additional 330 Wh of battery capacity. When combined with our massive 672 Wh Powerplay battery, you have over 1000 Wh to drain before it's time to rest.

Compatible with: Instinct Powerplay, Altitude Powerplay, Growler Powerplay
Capacity: 330 Wh
Weight: 2039 g (including mounting hardware)
Charging: 80% in just over 1 hour, 100% in 2 hours
Pricing: $799 CAD / $649 USD / 680 EUR

The Overtimepack drains its full 330 Wh capacity before you use any of the 672 Wh battery in your Powerplay. Your iWoc remote will read as fully charged until you begin to work your way through the main 672 Wh battery of the bike. The “RIDE MORE, FASTER, FURTHER” indicator on the Overtimepack will let you know how much of your 330 Wh battery remains.

Overtimepack draining sequence
Drain the Overtimepack first, then your Powerplay battery

No need to stop & swap batteries
Already plugged in, just keep riding.

Anti-rattle rigid attachment
Exterior battery mounts are notoriously sloppy. We offer a solid mount that’s designed for aggressive mountain biking.

Theft deterrent design
Tooled attachment discourages the theft of expensive accessories.

A more comfortable way to carry more energy
No need to carry a heavy battery on your back. Not only is it unsafe, but it can also throw your balance off.

A better handling eMTB
Overtimepack pack is located down low on the bike by the drive.


You can use the standard Powerplay 5A charger for the Overtimepack (while attached). You can charge both batteries in parallel with two separate chargers even more quickly. Overtimepack can serve as a Jerrycan charger, filling the main battery without a charger. It takes 2.5 charges of the Overtimepack to Jerrycan fill a 672 Wh Powerplay battery completely.

If the 672 Wh battery in your Powerplay is empty, the Overtimepack will charge your battery to nearly 50% in a little over 2 hours.

 “When combined with our massive 672 Wh Powerplay battery, you have over 1000 Wh to drain before it's time to rest.”

I think they meant to say “before it’s time to exercise.”

 I'm still not game for an ebike, but I do know a few very fit people with them and after 5-6 hours of riding shuttle laps with no truck they're tired AF. At least with the e-bike they're pedaling up for the same amount of laps as the truck.
  • 31 10

I had a go on one and riding up very steep hills you still have to pedal like mad. I was completely out of breath at the top and it was a hill I would have had to push-up on my bike.

I can see the point for certain terrain and disabled people.

 @Richt2000: why do you have to have a disability to enjoy an e-bike?
  • 29 12
 @Gavalar66: Being blind would help - nasty looking things, one and all.
  • 7 2
I didn’t say/mean that.
I said I can see the point for certain terrain (ie really steep stuff) and I can see the point for disabled people - eg if my knee joints were shot and I couldn’t pedal hard enough...

 You don’t know until you know! My first time on an e-bike entirely changed my initial thoughts on them. I laughed so hard, you challenge yourself to go real fast and have to handle uphills as well as downhills. Or go up technical steep climbs you would think impossible.

I’ve also gone out riding 1000x more often because when my fit af friends (aka most of the time riding with Bas) plan a big ride or go in an area known for a really tough climb, I no longer pass or choose to stay home for those, I’m happy to join the ride. And that’s 100% more exercise than not going at all.
E-bike are really fun and I’m happy for anyone who found their love on regular bikes or e-bikes. Xx
  • 18 2
 @vaea: Totally agree! I still get out and do my usual couple of rides a week on the mtb, I just do more riding now by riding another 2 times each week on the ebike as well.
  • 13 1
 @ali-chapple: Awesome! More riding time is the way to do it.
  • 13 2
 I did about that size ride on my conventional bike yesterday (35miles/7000ft) and I am stoked to have my E-bike today as I'll have a much more enjoyable recovery ride..
  • 11 2
 @ali-chapple: Same for me. I have family commitments, work, etc. With my ebike, I get in more total rides per week and still take my regular bike out as often as I did before. More riding=better fitness=more fun. All good things!

 Defo not for me however, I look with interest at the bike parks trying to open their doors again and of course in the UK - specifically Wales, most use mini buses. That is a difficult game to play at the mo. I wonder if will cause an increase in big travel ebikes as riders self shuttle? Time will tell.
  • 2 0
 @TheBrosCloset: IMO ebikes have lower centre of gravity. Corners become easier and super fun. You pedal up the track twice more than a regular enduro. you get used to the weight... I would say, ebikes are fun.
but* I still shred my normal enduro Slayer

 @Gavalar66: Ethically disabled
  • 39 7
 To the folks that are still throwing around the "ebikes are for the old, overweight, and disabled" cliche - just demo one!

You're still getting the workout we all enjoy. You just get to cover more trails in one ride, hit uphill lines you wouldn't have hit before, and explore new trails with confidence.

I'm 32, 155lb, 5'10 and still have both arms and legs. I'm fairly fit and have been riding for 8 years. A friend of mine talked me into demoing the Instinct Powerplay. With 2.6x 29 tires and 53lb I figured it would be slow, sluggish, and would handle like a pig. After 2 hours on it I sold my Intense Spider and got one that same week.

What ever they did with the fork offset and the chain stays makes the bike feel super flickable yet composed at speed. The weight of the bike disappears once you're pedaling, 3-4 hours rides only use about 30% of the battery ( I can basically do 2 days of riding on one charge), and I cover way more ground than I ever did on my trail bike. The weigh of the bike keeps it super composed through the rocks. Technical uphills are now a fun challenge rather than punishment. I don't have to check Trailforks to see if a new trail has enough descents to justify the climbing. Whats not to like?
  • 26 4
 I'm 35, ride 5 or 6 days a week, have done several 30+ mile/3500+ft days of climbing on normal bikes this year and demoed a ebike. I absolutely loved it and a 20 mile 5k ft of climbing trail that took half a saturday and involved a lot of hike a bike was a two hour after work ride. I'm absolutely in love with them and will buy one as soon as the 2021 models hit my local shop. Technical climbing is so fun and rowdy downhill is even better with the insane grip they have

Will I ride it every day? No, but for trail work days, self shuttling, and the odd day I just can't be bothered to lug my carcass to the top of something I'm in.

 I don't like the weight in the air. Doesn't feel very flickable and nimble. Once the weight comes way down I might be enticed because I like the idea.
  • 2 0
 @j-p-i: That's a fair point. If you plan on riding a lot of jump trails or want to throw some style while in the air I can see how the weight may get in the way a bit. Then again:

Which bikes have you demoed btw?
  • 1 0
 @j-p-i: Levo SL is uncanny. Rode it in Feb in SoCal before world went to hell. Big climbs and descents in the Malibu area. DH it literally felt like a typical trail rig. Year before I rode a Kenevo for a day, and that thing was a runaway schoolbus at the park.

 @giveherhell: Same, 31, 178lbs, no health issues. Managed a 3900m ride on the mtb, then 2 days later was still ruined but with the ebike, 'casually' did 1800m. I'm still inclined to choose the mtb over emtb, but there's plenty room for both and I love having the option.

I also love being able to put my daughter to bed at 7, then leave the house and get 2000m in before it gets dark!

 My 68 year old dad bought a Norco Scene to ride with my daughter. By no means is it a mountain bike, but it has convinced me that my next bike will be an E bike. More hours per day on stuff that I actually want to ride seems really hard to argue against. But so many people do!

I’m still going to wait a few years mostly because I want to see where the tech gets to in that time. But I will be satisfied with my Rsd hardtail until then.

 Love see peeps in the US finally comping on board. The main limiting factor at this point is trail access. At least here on the east coast, just not a lot of trails where you can legally ride one.
  • 3 0
 @roma258: I'm on the east coast myself and am curious about what this actually means. Is 911 going to respond to a complaint about someone using a pedal assist bike in the middle of the woods? Is a fellow rider going to attempt a citizens arrest? Practically speaking, how is this enforced?
  • 2 0
 @mgurvits: it's not. In my area i see people on ebikes all the time (usually old guys) on trails that don't allow them. Even then, most of the general public could hardly tell you anything about a bike other than it looks like one. The chances of them knowing it's an ebike unless the motor is making a ton of noise then reacting negatively to it is pretty far fetched.
  • 2 0
 @mgurvits: depends where you ride I guess. My home trails are heavily trafficked, if there were a ton of ebikes, it would get noticed and create issues. As it is, there are a couple I'm aware of, but few enough to stay under the radar. If you ride in a more sparsely trafficked area, you could probably get away with it indefinitely. But I am invested in the local community and work with them to open up more trails, build more features, etc with full co-operation of the local park system. Running ebikes against explicit wishes of the park's stakeholders works against that imo.

And I say this as someone who very much supports ebikes in general.

 I wouldn't mind trying one of those ebikes properly.. it really looks fun, and it sounds great to be able to cover 70-100km in one go off-road. I am just thinking, if you ever start, it will be even harder to go back to a normal mtb and work hard to get up hills... I am struggling with my weight as it is, so I think I stick to the old fashion bikes...
  • 15 2
 Yes, it's hard to go back to a regular bike. But I spend 4-6 hours on my bike every Sunday, and I'm getting way more exercise from that than I ever did with analogue bikes (bike parks are all uplift, and XC rides end after 2 hours). Now, I have way more opportunities to ride, especially because I don't mind the 40 min commute to my local mountain anymore. Adding 1:20 to a 3 hour ride was murder, and I hated to do it. I just ride much more often now than I used to, BECAUSE it doesn't hurt as much.
  • 14 3
 Can't wait to get one and see what crazy new adventures I can go on!

 Very cool. One day I'll switch to e-bike so can continue to have fun and psyched to see they'll keep on advancing thanks to all these improvements. Rock on.

 I’m 74 with damaged shoulders and lumbar back . without my e mtb i would not be able to ride .
I make a route that has a flat cruise section , a few undulating hills and one or two killer hills that require sport or turbo .
I make a point of trying to pedal non stop to the top , IF i don’t pass out first ???? to get my workout part of the ride in .
Then the last part of the ride is down hill to the flats where i cruise home .

 I reckon I can still last longer than a battery. Or even two batteries. I get E-bikes, their great fun, but where I ride a standard e-bike battery will be flat after 3/4 hrs, where my legs will continue on!
Also when they go wrong its a ball-ache. (I have worked in workshops, they go wrong a lot!)

  • 8 3
 @cliffdog: I'll defend you that you didn't say any of that, nor did I get a vibe of it. However, you gotta take the hit for what you actually said. Clearly, it's simple physics that if you (yes you) did a ride until you drop on your acoustic, then did the same on an E, you'd go considerably farther and longer on the E. You get that, right?

Then you tell everyone you know and you root for them and go to their shows, then they put out a new record and blow up then you hate them because they “sold out” and they’re main stream rather than being happy for them because they had success which is what you had originally hoped for.

 Bottles are OK for tiny 20-30 km rides. An Ebike with +1.000Wh is designed for 100km Epic rides, so you need to carry a lot of stuff: water, food, tools, clothes, etc...

 Not really. In the tool market batteries are approx $1-1.50/Wh, in Canada at least. A 20V 5Ah deeply battery will run $100-$150 for ~100Wh.
