FAQ
Front VS Rear?
Front elctric bike kits= easy to install, easy to maintain. This is the best for balance if you are using batteries on a rear mounted rack because of the weight.
Rear electric bike kits= harder to install, Installation only for the very mechanically inclined or professional. Only enough space for 7 rear speeds max Bad balance if you are using heavy rear rack batteries... Good points are that they are a slightly more natural feeling ride when using downtube batteries
Q:What's main advantages of geared motor and gearless motor?
A: Geared motor has lighter weight,smaller size,zero drag(complete freewheel when not using battery, and excellent efficiency./ Gear less motor has high top speed, more power output, and excellent life span.
Q: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.
Q: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.
Q: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.
