How To Motorize A Knee Scooter – Follow Step by Step Process

The best motor to use is a hub motor, which you can buy from your local electric bicycle shop. In the United States, this should cost between $250 and $450. 250 watts or more is recommended for optimum performance.

The battery you’ll need would be considered either a “deep-cycle” or an “automotive-type”.

Your local auto shop should have a battery to fit your needs. A 12-volt battery is sufficient for the average rider, who weighs between 130 and 200 pounds. You’ll also need a charger that can be plugged into an electrical AC outlet. Make sure that both the motor and the controller are compatible with each other, as well as the battery.

The next step is to choose a mounting location for the motor. Depending on your preference, this can be on either the front or rear of the scooter. The bracket that comes with the motor kit will need to be bolted onto the scooter’s frame. If you’re not cool doing this yourself, take the scooter to a local bike shop for assistance.

The throttle and the brake levers need to be connected to the motor controller. The throttle can be attached to the twist-grip or the foot pedal, whichever you prefer. The brake levers should be connected to the front brake on the scooter.

Once everything is assembled, it’s time to take it for a test drive! Make sure to wear safety glasses while riding if any debris flies up. Be cautious when depending at first, as you’ll be going a lot faster than you’re used to. Practice in an open area until you feel comfortable with the new set-up.
