Bottom Bracket & Sizing

All Rocky Mountain Powerplay models are designed for optimum user experience, both on and off the bike. The bottom bracket is located in the frame, not in the drive like other electric mountain bike models, ensuring an increased lifespan of the BB and easy serviceability for mechanics. When its time for a new bottom bracket, you do not have to send the entire motor in, you simply replace the bottom bracket.
