Product Description

Rocky Mountain decided that the best ebike they could create would come totally inhouse, and the Altitude Powerplay Carbon 70 is the result of this. The new Powerplay system with motor and battery was developed completely by Rocky Mountain, giving them the freedom to customise it to suit their purposes. It features exactly the same geometry as the Altitude trail bike, delivering nimble handling, while the motor will get you up and over any climbs. Fox suspension front and rear and SRAM RE disc brakes give you complete control on the mountains and the RIDE-9™ allows you to alter the geometry and suspension rate in 9 different settings.

  • SMOOTHWALL™ Carbon frame with RIDE-9™ Adjustable Geometry + Suspension Rate
  • Fox Float DPS EVOL Performance shock controls the 150mm travel
  • Fox Float EVOL Grip Performance fork is E-Bike optimised and has 160mm travel
  • SRAM EX1 electric bike specific drivetrain gives 8 perfectly spaced gears

Ride more, further, faster. The Altitude Powerplay brings cutting-edge power to an aggressive trail bike, and opens the door to amazing terrain for all.

Introducing a fully integrated, electric-assist mountain bike that takes our Altitude’s legendary handling and ride quality and adds a compact, powerful drive system. The new Powerplay™ drive system was designed in parallel with the frame, delivering ultra-short chainstays, optimised suspension kinematics, super-low centre of gravity, and class-leading torque. The result is an e-MTB that actually rides like a proper mountain bike—perfect for everything from self-shuttling all mountain trails, finding flow between the descents, and squeezing in power lunch rides.

It’s an Altitude

The Altitude Powerplay has the same geometry and suspension performance as the unassisted Altitude platform. It is the first e-MTB that features true aggressive trail ride feel.

Next generation drive system

The Powerplay™ drive system was designed from the ground up to allow true mountain bike performance, while providing class-leading torque, massive battery capacity, and ultra quiet operation.

Intuitive pedal assist

An in-line torque sensor provides smooth, instant power response, making for an intuitive, natural ride with no learning curve. Get on and go.

Charge fast, then charge hard

The 48v motor provides super short charge times, taking only two hours to reach 80% capacity of the available 632Wh lithium ion battery.

Fully supported

Easily serviceable components, with both replacement parts and strong dealer service support in Europe.

Made in Canada

Powerplay™ drive Frame Construction

Designed by us in Canada, the Powerplay™ drive system is a sleek, lightweight, and powerful electric assist that pushes the boundaries of electric bikes. Its compact, low-mounted motor allows us to design electric mountain bikes to our suspension and handling standards—with proper geometry and ideal pivot placement. The system provides class-leading torque, ultra quiet operation, instant power response, and super fast charging.

Smoothwall™ carbon Frame Construction

Smoothwall™ carbon uses one of the world’s most sophisticated carbon processes to deliver industry leading stiffness-to-weight, ride quality, and durability. We eliminate excess resin and fibers by using rigid internal molds instead of traditional air bladders. We then utilize different types of carbon in specific frame areas to maximize stiffness and impact resistance while minimizing overall weight.

Size Specific tune Suspension

Size Specific Tune ensures that riders of all sizes get the right balance of small-bump compliance, mid-stroke support, and end-stroke progressiveness. Our design team does custom shock tunes based on real world field testing, and adjusts each tune for specific frame sizes.

RIDE-9™ adjustment system Geometry

The RIDE-9™ adjustment system allows riders to quickly fine-tune their geometry and suspension with a pair of Allen keys. Nine configurations are possible thanks to two interlocking chips.

Smoothlink™ suspension

Smoothlink™ suspension is efficient yet supple when you’re on the pedals and across a wide range of gears. It features a controlled end-stroke and a rate-curve that feels more capable than the travel would suggest. This four-bar suspension design philosophy is centred on ride characteristics; each bike platform we develop balances variables like anti-squat, axle path, chain growth, rate curve, anti-rise, etc. to achieve the legendary Rocky Mountain ride feel.
