Amazing bike, quick. On the flat average 21mph full power, after 3-4 miles average 18mph. A lot of hills in SoCal so this 1/3 hp motor does it’s job well with pedal assist on very steep grades. With electric only mode and heavy, steep, long hills this bike does its job pushing through a 16 mile commute with some energy to spare with a 190lb load of me and my gear. This bike could do much more with flat and pedal assist modes maybe twice as far. Recommend you use smaller tires 1.75 vs the standard 1.95 to achieve my results. Continental contact travels work great!
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.
It is not a off-road motorbike with an electric engine and a throttle. Electric mountain bikes have motors that only work when you’re pedalling. The motor tops-up your pedalling input. It’s called ‘pedal assist’. There are differing levels of assistance (called things like ‘eco’ and ‘turbo’) that you select via a handlebar-mounted control unit. The motor also cuts out once you reach 25km/ph (or faster). There are strict limits on the power of electric mountain bikes; 250w is the maximum nominal power. More powerful than that and the bike requires tax and insurance (like a car/motorbike) and is also not allowed on bridleways at all.
My wife has a Scott, essentially a Contessa with a Bosch crank motor. Very heavy thing, bloody hard work with no assistance, but even with assist on progress surely depends on your effort. We don’t do a lot of trail centres, but it’s been fine round Rothie, up to Einich, in Inshriach and up the Corbett behind Kingussie, as well as onroad. Lets us ride together, which would be harder without assist, and is heling her recover from skiing injuries.
Yep, there’s no getting away from the fact that i’m peddling a 21kg bike when the assist is switched off but with the massive battery & range there is no real need to switch it off, I can barely turn the pedals on a normal bike when i hit a hill so if i’m on the road and wanting as much range as possible to explore a few of the surrounding trails in my area of Galloway i’m quite happy using the eco mode to get myself around, the tour mode gives a bit more assist and is enough to tackle the majority of single track climbs with effort from myself, the sport mode is enough for all but the steepest of singletrack use and the turbo mode is just batshit mental for all out super steep climbs and so much fun.
