Full-Power Enduro. No Compromise.

The Rocky Mountain Altitude Powerplay Alloy 50 is built for riders who want the capability of a serious enduro bike with the added punch of a full-power eMTB system.

With 170mm of front travel, 160mm of rear travel and Rocky Mountain's Dyname S4 Pro motor, the Altitude Powerplay is designed to charge steep climbs, technical terrain and fast, rough descents. The Powerplay platform combines Rocky Mountain's aggressive enduro geometry with adjustable RIDE-4 geometry, giving riders the ability to fine-tune the bike's handling to suit their terrain and riding style.

At the heart of the bike is the Dyname S4 Pro drive system, delivering up to 1,000 watts of maximum power and approximately 110Nm of peak torque, paired with a 720Wh removable battery. The system uses Rocky Mountain's integrated Jumbotron display and Micro Remote to keep the controls clean and intuitive.

Built for Aggressive Trail Riding

The Altitude Powerplay A50 is more than an e-bike with extra suspension. Its chassis is designed around aggressive enduro riding, with a slack 63.5° head angle in the slack RIDE-4 position, a steep effective seat angle, long reach numbers and a size-specific approach to handling.

The RIDE-4 adjustment system allows the geometry to be changed between four positions, altering the head angle, reach, bottom-bracket height and overall handling. That means you can set the bike up for more stability and confidence on steep terrain or a more responsive feel for tighter trails.

The A50's geometry changes with the RIDE-4 position. The following chart shows the neutral geometry alongside the slack and steep positions for the primary measurements.

Geometry figures are in millimetres/degrees and can vary according to wheel configuration and RIDE-4 position.

Why Ride the Altitude Powerplay?

The Altitude Powerplay is aimed at riders who want real enduro-bike capability without giving up the extra range and climbing performance of a full-power eMTB.

The combination of the Dyname S4 Pro motor, 720Wh battery and aggressive suspension platform makes it particularly well suited to long days on technical terrain. On the way down, the 170/160mm suspension package, slack front end and adjustable geometry give the bike the chassis to handle steep and rough trails.

And unlike many eMTBs that feel like their geometry was designed around the motor first, the Altitude Powerplay is built around Rocky Mountain's established Altitude enduro platform.
