Variable time of motor torque reduction while shifting. It is performed on the basis of current gear position and specified parameters in combination with system data collecting. This solution makes it possible to minimize time of the of motor torque reduction during the gear change, while it is also preventing motor from restarting before the gear change is finished. Shifting parameters are defined by rider via display input, according to riderâ€™s individually preferred pedaling cadence and several shifting time parameters values.
Recommend to the rider optimal moment to change the gear position. Based on the optimal usage of the electric motor's efficiency combined with other data collected from the system. The effect is to save battery energy, namely the elongation of the riding distance per one battery charge. Advice is done in the form of graphic arrow symbols showed on the display.
Display the information about the gear position on the display screen.
This drive unit moreover offers sensorless sinusoidal field oriented control programmable controller, which allows e-bike manufacturers to tune system behavior by setting various parameters.
Modular specification system allows customer to create specific drive unit according to his individual requirements. The customer can put together a final drive unit specification by selecting the following optional items:
