SpeedFun Furious Evo Easy per Brose

SpeedFun FURIOUS for Brose is a revolutionary tuning kit which suppresses the speed limiter of your electric bike.

After installing your SpeedFun, your e-bike’s display will show real data up to 12mph (20km/h) - at higher speeds, the display will show half speed and relative data making it possible, by simply multiplying in mind by two, the calculation of the actual speed and miles or kilometers traveled.

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.

You can choose the 'On/Off' or 'Easy' tuning kit:

'On/Off' option - The chip can be activated or deactivated anytime during the ride by pressing LIGHT BUTTON.

'Easy' option - The chip is activated automatically when you turn your e-bike on.

This tuning kit can be installed on ebike with Brose in aluminum (Brose C, Brose T, Brose TF, Brose S) or with Brose motors in magnesium (Brose S Mag) and Continental motors.
