Controls Edit

Brakes Edit

The braking system is managed by a Goped Maddog caliper and rotor on the front wheel. The electric motor controller system does not provide regenerative braking, but the movement of the engine will decelerate the scooter if you let off the throttle.

Throttle Edit

The throttle is operated via a thumb lever on the right side of the handle bars. It interacts with the controller system underneath the deck to control the amount of current going to the electric motor.

Adjustments Edit

ReliabilityEdit

You'll never have to replaceEdit

You may eventually have to replaceEdit

The brush card. As the electric engine ages, the brush/commutator interface will get worn and may need replacing. These little motors do last a long time though, so replacing the motor should be of little concern.

The batteries. Over time, the SLA batteries will lose their capacity and will require replacement. Since the batteries are of a common variety, replacements are common and relatively inexpensive (~$70). You should be able to get 300-500 cycles out of the batteries before capacity will fall substantially.

You should immediately replaceEdit

The front sprocket. Some ESR750s were released with out-of-round front sprockets attached to the engine. You can tell if your sprocket is out of round by lifting the back wheel off of the ground, engaging the throttle and watching the auto-tensioner's movement. Here is a video example of what an out-of-round sprocket looks like (watch the tensioner jumping up and down). An out of-round_sprocket can cause the chain to jump off of the rear sprocket and cause damage to your scooter and even lock up the back tire and cause a crash. Goped will replace the sprocket for free if contacted.
