Rocky Mountain Growler POWERPLAY 30 Hard Tail 2021



The Growler Powerplay will bring your confidence up to speed in a hurry.

By combining high volume 27.5+ tires with the power of our Dyname™ 3.0 drive system, this hardtail will have you charging hard on the trails. So, go the extra distance, forget about your struggles with punchy climbs, and celebrate after with a post-ride pint.

Rocky Mountain stand behind their products. They’ve increased the warranty on their electrical components from 24 months to 36 months, making it the best in the industry in terms of coverage length. This change is retroactive and will apply to all Powerplay models from their purchase date to present day, and into the future. Sweet.

    Rocky Mountain took the Instinct's legendary handling and ride quality and integrated the most powerful drive system on the market and bam: one of the most powerful, most capable e-mountain bikes ever. With v1 it impressed with its gorgeous, clean look and a ride feel that was as good as a non-motorized mountain bike and it has only gotten better.

    Rocky Mountain designed their own drive system, the Dyname 3.0, so they could retain the geometry and great handling characteristics of their non-motorized models rather than having to design a frame around an off-the-shelf drive system. It was worth the wait.  The Growler Powerplay is a true no-compromise e-mountain bike. 


    Ride more, faster, further

    While developing the first-ever Rocky Mountain eMTB, they refused to be held hostage by existing drive designs. They built the drive to fit the bike, not the other way around. For ten years, their engineers dreamed, created, tested and meticulously improved upon Dyname until they got it right. The Dyname drive is compact, powerful, and smooth. It facilitates pure, unbridled design freedom, as evidenced by the seamless integration of the RIDE-9 adjustment system.

    Lower RPM

    Dyname spins at 1200 RPM (1/4 the competition's speed). Less whine. More efficiency.

    Tuned to the key of human

    Specifically designed to an MTB-friendly cadence and real world singletrack riding. No spinning out.

    Higher torque

    Virtual quads kick in when you need them and stand down when you don't.

    A motor's intuition

    Seamless power modulation between drive and human. Dyname reads your rhythm and responds to your ride.

    Proprietary design

    Three patents. In-house customization. Limitless design freedom.

    Better BB

    The bottom bracket is part of the bike, not the drive. No creaking, less wear, and local shops can service it. We love local shops.

    Step on it

    When you step on the pedals, the Dyname 3.0 drive delivers immediately. Competitive systems can exhibit lag, apply power too abruptly (causing wheel spin or loss of control), and generally introduce odd sensations to riding. With Powerplay, beginning on a hill is easier than ever. Getting up to speed is simple. Dyname's electro-mechanical torque sensor measures chain tension through movement of a magnetic field, providing instant input to the brain of the drive. Less lag. More power.

    Dyname needs to crunch numbers quickly, and lend support to the rider even more rapidly. When the chain moves, Dyname reacts instantaneously. How? Every time the chain straightens out, a magnetic field sensor measures the chain position. This sensor measures 1000 times per second. This extreme sensitivity helps maintain traction on greasy trails, allows for subtle torque modulation on complex terrain, and produces a natural-feeling power output.

    Ahead of the curve

    The Dyname 3.0 Drive features class-leading power, and torque measuring in at a 108Nm*. This means you can crush steeper hill climbs faster, and accelerate like a speed demon. No strange pedalling sensations. Modulation so smooth you won’t even notice the RPMs kicked in.


    Optional Overtime extra battery pack.

    The Overtimepack allows you to ride your Powerplay farther than ever before, putting more time in on the trail before needing a charge.

    The Overtimepack is a range extender for our Powerplay lineup that offers an additional 330 Wh of battery capacity. When combined with our massive 672 Wh Powerplay battery, you have over 1000 Wh to drain before it's time to rest. It's about more saddle time, more trail time, and more of the good times.

    Drain the additional Overtimepack first, then your Powerplay battery

    The Overtimepack drains its full 330Wh capacity before impacting the 672Wh battery in your Powerplay.

    Your iWoc remote will read as fully charged until you begin to work your way through the main 672Wh battery of the bike. As you use up the Overtimepack battery, the LED indicator that reads, "RIDE MORE, FASTER, FURTHER", will begin turning off. Once you tap into your Powerplay battery, the iWoc remote will indicate the remaining battery capacity.

    Top up your Powerplay battery

    If the 672Wh battery in your Powerplay is empty, the Overtimepack will charge your battery to nearly 50% in a little over 2 hours. Just plug it into the bike and let it transfer the battery power into your bike.

    Using the standard Powerplay 5A charger, you can charge the Overtimepack in a little over 2 hours. Do not use any chargers other than the standard Powerplay 5A charger, as they will damage the Overtimepack battery.
