2 Year Parts only Motor and Battery, 1 Year all other Parts. Hub Drive Versus Mid-Drive Technology.
Most electric bicycles have hub drive motors. Hub drive motors are fine if you travel on level terrain. The problem with hub drive motor is when you travel up hills this can cause the motor to overheat and the battery to drain very quickly. If the hill is more than about 3 degrees of incline, hub motors will drain your battery quickly, and could overheat and fail. Hub drive motors do not make use of the gears, so a multi-speed Hub Drive electric bicycle will not make use of the gears in electric mode.
All hub drive motors only have one speed/gear ratio. The gears on a Hub Drive electric bicycle will only function/change when you pedal. A Mid Drive electric bicycle has a motor which is connected directly to the pedal shaft.
This allows the gears on the rear axle to be active while in electric mode, so changing the gears or speed will directly change the motor speed/ratio. With a Mid-Drive motor, you can climb the steepest grades, hills and mountains with ease using only electric power & no pedaling. Problems with most Mid-Drive Technology. Most Mid-Drive electric motors are designed for auxiliary climbing only, which means that in order to prevent the motor from overheating, you must limit your hill climbing to less than 3% duty cycle. This means that you must climb only very slight grades, very short distances in electric mode, or you must pedal assist to keep the motor from overheating.
Overheating your motor, causes both the motor and the battery to overheat, which will lead to reduced battery capacity, reduced range and premature failure of both the battery and motor. In many cases, climbing hills regularly can lead to instant failure of the battery, motor or both. So while any Mid-Drive motor is better for climbing hills than Hub Drive motors, you need the right Mid-Drive technology for a good hill climbing electric bike.
Why our Mid-Drive Technology is Superior. Our Mid- Drive technology is superior to most other Mid Drive electric bicycles and here is why. 1 We have a 1000 Watt motor which has much more power than most motors. This means you will need less throttle to climb hills and this will reduce motor and battery heating.2 We have an extra large cooling fan on our motor. This extra large fan has the capacity to assure the motor stays cool even at 50% duty cycle. This allows you to climb much longer, steeper hills without overheating. This produces less strain on your battery too. 3 We have a 7 speed rear axle which allows you to change the gear ratio of the electric motor. By having the ability to gear down on steeper grades, you can greatly reduce the heating of the motor and battery.
This will extend your battery capacity, range and life and greatly increase the life of your motor. 4 Our braking system has Motor Cutoff Sensors built in which will cut power to the motor when the brakes are applied. This greatly reduces heating & strain on the motor and battery.
