Rocky Mountain Le e-bike sono note per la loro elevata qualità costruttiva e per i loro motori estremamente potenti che le rendono tra le migliori e-bike di sempre. La prima Rocky Mountain engine was developed in 2009 but only in 2012 with the release of the 2nd generation engine (Dyname 2.0) il primo motore è stato montato su una ebike, in questo caso è stato montato su una ebike urbana. Il primo Altitude Powerplay, which is the 3rd generation of the Dinamo Il motore è stato lanciato per la prima volta nel 2017. Nel 2019, altri tre motori sono stati aggiunti alla famiglia Dyname: Altitude Powerplay, Istinto Powerplay, E Growler Powerplay.

In the late 2021, Rocky Mountain announced the release of the 4th generation of the Dyname engine (Dyname 4.0). The new drive system delivers the same torque as its predecessor (108 Nm) and it is 18.5% lighter. But there is more to add to this class-leading engine since the Dyname 4.0 drive unit has now a torque sensor that reads the tension applied to the chain allowing the engine to gradually reach maximum power without unwanted lag time. In addition to this, a new torque curve has been developed which allows the engine to reach maximum power at lower rpm (85 rpm).
