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.
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 three levels of assistance, the the ANCHEER Power Plus lets you enjoy a fun and easy ride every time . If you want to reach your destination without breaking a sweat, the Pure Electric Mode or full throttle mode will give you the full power you want. But, if you want a light cardio workout but with a little assistance, use the Pedal Assist Mode. Want the feel of a traditional bike? Use the Regular Bike mode.
The 250 W motor may seem a little on the small side but it’s quite capable. It gives a top speed of almost 16 mph without any form of pedalling. The acceleration is decent, aided by the low weight of the bike. However, it can’t really compete with bikes that have 500 W or higher motors. These do tend to cost more than the $1000 mark though. The battery is said to give it about 30 miles maximum range when in assistive mode. The battery is able to fully charge in 4-6 hours. 

The frame is solid. In fact too solid for me. The frame is thick with such a girth that my rear wheel bike rack doesn't fit (around the frame or into the pre-drilled holes because the disk brake is in the way). Shocks seem to work fine. I do enjoy having the kick stand further back, provides a lot more stabilization to the bike vice being closer to the pedals.
