Company profile
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. The faster you pedal, the more power is applied. PAS mode significantly increases battery range as compared with using the throttle alone. 

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 to pedal without the motor. Unfortunately physics doesn't work in our favor.

Q4:How far can I go on one charge?
A:There are many variables that affect distance such as weight, terrain, number of stop / starts, riding speed, amount of pedal assistance, number of hills climbed, tire pressures, and wind resistance etc.

Q5: Front wheel and rear wheel choose which one? 
A: Common standard front wheel is 100mm dropouts,easier to install without derailleur adjustments, you can use your original freewheel; Common standard rear wheel is 135mm dropouts, better grip especially when you ride on steep inclines or in wet condition.
