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.
Meter with 3-speed smart buttons: The speed button helps you to choose how first you want to go. The bike is by default at ‘’low’’ level. To increase the peddle assist level, press the ‘’+’’ and you will switch from low, to mid or high. “High” is the maximum level that will provide fast speed while pedaling, and to decrease speed level you need to press the ‘’-” button. The ’-” can also be used to eliminate the three pedal assist levels and switch into pure E-bike where you are only required twist the throttle as you cruise all the way.
Weight isn’t anything like a critical as one would assume. Weight distribution however is a different matter and this is where geometry, specifically the ratio of the front centre measurement to the chain stay length really comes into play. Battery placement is important too, and smaller batteries give an edge in the handling stakes while robbing the bike of range.
The bike comes partly disassembled for shipping, so you'll have to attach the handlebars, pedals, front light, quick-release saddle and front wheel. In all, it'll take you around 30 minutes including removing all the cable ties and packaging. The tools to do this are included, but you might prefer you use your own screwdriver and spanners as the supplied tools are poor quality.
It was easy, good tools were shipped with the bike. The instructions are nearly useless, though. Like other reviews state, the front fork is backwards in the picture and shipped backwards. The disk brake should be on the port/left side. Flip the handlebar clasp around and leave the dirt guard facing forward. All the cables should flow naturally this way. Pedals were ok to put on, one of the pedals took a minute to get threaded but eventually got tightened.
