Introducing the Rocky Mountain Powerplay Family of E-Bikes
We are pleased to add the Rocky Mountain Powerplay E-MTB family of bikes to our already all-star lineup of bicycles. We have been part of the Rocky family for over a decade and the company’s dedication to building a better bike has always been part of our mantra of offering only the best to our customers as well.
Rocky released its first Altitude Powerplay in early 2017 in Europe. Since then, the E-MTB platform has expanded with the introduction of Instinct and Growler Powerplay models.
The folks at Rocky Mountain have always been very deliberate and methodical when it comes to designing, manufacturing and riding bikes. The company’s entry into the E-MTB arena is no different and the results are game-changing.
From the start a decade ago, Rocky’s goal was to create electric-assist bikes that perform just like its stellar lineup of “acoustic” models. It didn’t take long for the company’s engineers to realize they were going to design a new and different drive system to accomplish that goal. Current third-party motors require changes in the frame geometry, making those E-bikes longer and less agile. Rocky created the proprietary Dyname 3.0 drive system enabling the company to deliver an E-MTB frame with the shortest chainstay in the industry.
The Powerplay design is broken down in to four basic parts:
Drive mechanism


iWoc/controller
The sleek, third-generation remote control is more compact, robust and intuitive. There are three levels of assist: eco, trail and ludicrous. When you want to walk the bike, simply tap the walk mode and it will slightly push the bike forward helping you overcome the extra weight.
Battery and integration
The battery is integrated into the downtube, eliminating the bulky battery attachment and case necessary to house the existing third-party systems. This not only reduces the weight of the bike, it also makes for a more traditional look and ride.


App
Everything is managed via an app on your phone. The E-Bike Motion app features GPS and integrates with other cycling apps like STRAVA. All diagnostics are done through the app and you can customize your assist settings based on your preferences. The app will also monitor your battery usage and then calculate how far you can go and how long it should take before the battery loses power. It’s as easy as 1-2-3 and is LUDICROUSLY fun in every mode.
Why E-MTB?
Well, the first thing you ought to ask yourself is “Why not?”
Electric mountain bikes put the “social” back into mountain biking. Having a little help from an electric-assist motor can keep riders with varying fitness and riding levels together, all having fun at the same time in the same place.
E-bikes might make it easier to tackle terrain and go farther but that doesn’t mean you’re not going to get a workout. You can ride more aggressively uphill and it will change your paradigm when it comes to the climbs. The bikes soar downhill giving you a feeling of confidence and thrill at the same time. It’s a different type of riding and equally as fun as your current bike. You’re not replacing your acoustic playmate. You’re adding to the team.
We have been a bit hesitant to dive too deep into the e-bike pool until now because we felt existing bikes and drive systems needed additional tweaks and refinements to make them perform better, weigh less and provide an exceptional experience. We believe Rocky’s Powerplay e-bikes do exactly that. We’re excited to bring Rocky’s family of E-MTB models to you. We are confident you will be as blown away by their performance, style and excellent riding characteristics as we are. Let’s ride!
