With most ebikes the choice of motor defines aspects of the frame geometry and to a lesser degree the suspension characteristics of the bike. Not with new Rock Mountain Altitude Powerplay. With its bespoke motor Rocky has been able to design an ebike that reflects the ride quality of a highly evolved 150mm trail bike. With instant power pickup, extended battery life and streamline proportions it’s not just the handling of the Rocky that will get you charged up for riding. It’s the best bike in this test by some margin, but we had an issue with the motor momentarily cutting and raising questions over it’s reliability.
Had my first crash on this bike. Right at the 500 mile mark mid-November. Sand had blown all over the bike path and I took it too fast. The bike did ok, but when I picked it back up the motor wouldn't work. I pedaled the rest of my commute and got a ride home. I suspected (and was correct) that the left brake lever was bent and the motor was not able to engage because it thought I was braking. I was nervous muscling it back, but it wasn't bent too bad. So that's what I did. And I also took the time to replace both wheels, inner-tubes, and give the bike a cleaning. The front wheel was still ok on tread but the back wheel tread was completely gone. Changing the front wheel was easy. The back wheel was more challenging because the motor cables and disc brakes. Ended up leaving the wheel on the bike and just moving it slightly to get the tube and wheel in place. Ended up just being more annoying than difficult. The chain cleaned up nice with some Simple Green. I haven't ridden on the commute nearly as much with me feeling a little more cautious and it getting dark so early (I don't need to wipe out in the bike lane into traffic...) All is well though. Have had zero issues with the motor since bending the brake back to its (or close to its) rightful position.
Firstly this is not a motorcycle. I bought this to use as a daily commuter.I now have 1000 + miles on it. The pedal assist works fine and may be ok for leisurely riding but I just use the throttle and pedal. This is a great bike. Strong frame and wheels. Been in two crashes and no damage. The tires are nice off road tires and now live on my daughters mountain bike. I switched them out for high pressure road tires. Forget about the horn and light. They don't work. I am 6'1" 32" inseam and had to buy a longer seatpost($30) to fit this frame. 13miles each way commute. Battery life is fine. After the 26 mile round trip it has a little juice left but not enough for another ride to work. I would buy again.
