The Altitude Powerplay is one of three bikes on this list (Specialized Turbo Levo and Liv Intrigue E+ are the others) to use a custom motor. The Dyname 3.0 motor offers 100Nm of torque and is also compact enough that Rocky can use the same geometry and suspension-pivot placement as an unplugged Altitude, so the Powerplay feels more like an unplugged bike than most e-bikes. With the motor off it rides like a standard, albeit heavy, trail bike. The motor responds more quickly than some of the more popular systems and the increased torque offers increased acceleration, which, depending on the trail situation, can be welcome or a hindrance.
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.
