Main Product Information

SpeedFun Furious Evo easy+ for Rocky Mountain Dyname 4.0 is a revolutionary tuning kit which suppresses the speed limiter of your electric bike.

When the device is active, the display will show the exact speed up to the threshold of approximately 15 KmH, beyond which a manipulated speed will always be shown below 25 KmH.

The tuning kit manipulates the speed signal without altering the motor's power relative to pedaling speed. This guarantees a smooth motor control without speed limit interruptions. Depending on a tuning kit, some determine when assistance stops, while others remove the restriction entirely for continuous support. However, the achievable speed mostly depends on the eBike model. Achievable speed can be calculated using a simple formula:

Speed = Cadence [rpm] * Wheel circumference [mm] * Front Chainring Teeth / Rear Chainring Teeth * 60 [min/h] / 1.000.000 [mm/km]

After installation, your tuning kit will be activated with the activation of your eBike. Maximum speeds of ~30mph (50km/h) or even faster can be expected, depending on the bike and gearing.

This speed unlocker is compatible with Rocky Mountain Dyname 4.0 motors from 2022 equipped with a 720Wh Powerplay battery and Jumbotron display.
