SpeedBox 3.0 for TQ HPR120S, FLYON motors

SpeedBox 3.0 tuning chip enables to select speed limit of your own choice. After the chip is installed, your e-bike’s display will show real data, such as maximum and average speeds, daily mileage and cruising range.

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]

The tuning chip can be activated via the e-bike‘s control unit. To activate or deactivate tuning, use the → ← → ← button sequence in order to switch between two assistance modes twice. The actual speed limit will briefly appear on your display and the motor will support you up to this speed.

To deactivate the tuning kit, use the → ← → ← button sequence again. The value of cadence of 25 rpm will appear on your display and the speed limit will reset to 25 km/h. Your e-bike will then work the same as before installation of the chip. You can set the maximum speed of an electric assistance by changing the following modes gradually: EXTREME - HIGH - MID - LOW - MID - HIGH - EXTREME.

An actual speed limit will be displayed after that. The maximum speed of an electric assistance can be switched by turning the rear wheel about 180°. The cadence of 15 rpm on the display corresponds with the limit of 15 km/h, 20 rpm corresponds with the limit of 20 km/h, 25 rpm corresponds with 25 km/h, 30 rpm corresponds with 30 km/h, 99 rpm corresponds with 99 km/h etc. The last displayed limit will be saved after 5 seconds of inactivity.
