FAQ

Q1:What's main advantages of geared motor and gear less motor?
A: Geared motor has lighter weight,smaller size,zero drag(complete freewheel when not using battery, and excellent efficiency.Gearless motor has high top speed, more power output, and excellent life span. 

Q2:What is Pedal-Assist?
A:The Pedal-Assist Mode (PAS) operates when you are pedaling the bike and progressively adds electrical power to the motor. Thefaster you pedal, the more power is applied. PAS mode significantly increases battery range as compared with using the throttlealone. 

Q3:Does the battery recharge when I pedal?
A:No, in order for the motor to recharge the battery, it would have to create resistance which would make it too difficult topedal without the motor. Unfortunately physics doesn't work in our favor.
