Rocky Mountain Altitude Powerplay A50 E-Bike 2027Highway to Shred If you love big descents but not the long push back up, a full-power enduro e-MTB gets you more laps in. The Altitude Powerplay A50 runs the Dyname S4 Pro motor, with 110Nm of torque and 1000W of max power. That's plenty of help for steep, loose climbs and long days on the saddle. A 720Wh battery sits inside the alloy frame and comes out for charging. When you want to stay out longer, an Overtimepack 2. 0 adds another 314Wh. The frame pairs 160mm of rear travel with a 170mm fork on 29" wheels front and rear. With the RIDE-4(TM) Adjustable Geometry the flip chip lets you tune the suspension rate, and the frame carries a 5-year warranty that transfers to a second owner. Suspension is split between Rock Shox and Fox, with a Zeb Select RC fork up front and a Float X Performance shock out back. The Zeb keeps the front end steady through rock gardens and hard landings. SRAM Eagle Transmission shifting runs across a 10-52T cassette, so there's a low gear for the steepest pitches. SRAM Maven 4-piston brakes bring the stopping power you want on long, steep descents. WTB rims wear a Maxxis Assegai up front and a Minion DHR II out back, both with tough DD casings and ready to run tubeless. A Tranz X dropper with size-specific travel gets the saddle low before the trail tips down. Up top, the Jumbotron display shows battery level, assist mode, and speed at a glance, and the Micro Remote lets you change modes on the fly.
