Addmotor Greattan Controls: Assist Levels, Gears and Differential
Addmotor Greattan controls bring together electric assistance and a mechanical transmission. The specification also mentions a rear differential. These features do different jobs, so learning one control does not explain the others. A useful handover demonstrates each function separately before combining them on a ride.
Electric assistance in the Addmotor Greattan controls
The official page lists seven pedal-assist levels with a torque sensor. This describes the assistance system, not seven mechanical gear ratios. Ask the demonstrator to identify the display controls and explain what the selected setting means on the exact trike in front of you.
Begin with the machine stationary and the demonstrator in control of the setup. Have them point out the throttle and explain how unintended activation is prevented during mounting or handling. Follow the model's instructions rather than assuming controls work like a previous electric bike.
Gears are a separate selection
Addmotor lists a Shimano seven-speed rear derailleur and shifter. That transmission changes the mechanical pedalling relationship. The assist selection and gear selection therefore deserve separate attention: two settings showing the same number do not necessarily describe the same thing.
During a guided demonstration, ask which control changes gears and have the staff member show the appropriate shifting technique. Focus on finding a comfortable pedalling rhythm. Do not attempt adjustments to the derailleur simply because a shift feels unfamiliar; report the symptom and let a qualified person check it.
The differential does not replace steering judgement
The Greattan page identifies a rear differential. Its role concerns how the rear wheels can turn at different speeds through a bend. It is not an extra assist level, a rider-operated gear or a promise that any corner can be taken at any speed.
Ask for a slow, supervised turning demonstration in an appropriate space. Pay attention to the rear-wheel path and the room needed around obstacles. The old expo photograph provides Greattan-family context only; it cannot show the calibration or condition of a machine's controls.
Use the test-ride checklist to record what you can operate confidently. The Addmotor reference topic connects these control questions with fit and cargo planning.
Drivetrain terminology FAQ
Are seven assist levels the same as seven gears?
No. Electric support settings and mechanical ratios are separate systems with separate controls.
Do I select the differential on the display?
The cited page describes it as a rear-drivetrain feature, not a display setting to choose.
Can a specification explain how confident I will feel?
No. Arrange a guided demonstration and assess the actual reach, starts, stops and turns.
Understanding Addmotor Greattan controls means knowing which function you are changing, then practising the approved operation with suitable guidance.
