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 ultrashort 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.

“The most exciting part of riding the Altitude Powerplay for me is pushing my own boundaries. I'm not going to ride this bike on my every-day loops, it's a tool I’m using to push my mountain bike boundaries even further – push to a point I wouldn't have otherwise realized existed. I live to ride, and I've been fortunate enough to see a lot of major movements in mountain biking. The introduction of e-mountain biking is definitely the most exciting.” – Wade Simmons

The Altitude Powerplay™ was designed and built with the same passion and enthusiasm for mountain biking that has pushed Rocky Mountain Bicycles forward for the last 37 years.

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 system 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 Canada.

This 3rd generation of drive system was designed and developed by Propulsion Powercycle and Rocky Mountain Bicycles in Canada. The Powerplay™ is a patented mid-drive system that’s under exclusive license from Propulsion Powercycle. The Powerplay™ drive system is a sleek, lightweight, and powerful electric assist that pushes the boundaries of electric bikes with its smooth, instant power response and intuitive ride feel. The Powerplay™ was designed in parallel with our frame, allowing us to produce an e-MTB with the same geometry and suspension kinematics as our unassisted altitude. The system provides class-leading torque, ultra-quiet operation, instant power response, and super-fast charging.

Our carbon bikes, including the Altitude Powerplay™, 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.

The Altitude Powerplay™ has a FORM™ alloy rear triangle, engineered to ensure optimized strength, weight, and ride quality.

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 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.

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