Mobility Scooter Parts

AGM battery - An abbreviation for “absorbent glass mat”. These batteries have a high power density and recharge very quickly, making them useful in high-performance electric vehicles.

Comfort Ride™ seat suspension - Comfort Ride seats feature a maintenance free air-suspension pedestal. Drivers can use a fingertip control to adjust ride and height, and position their bodies directly over the suspension with a double-locking pedestal slide.

controller - A device which manages the distribution of power from the battery to the various electrical components of a scooter. When replacing a controller on your electric scooter, it is very important that you obtain a controller with the proper voltage for your scooter model. Contact the manufacturer or consult your owner's manual to obtain this information.

delta tiller - A roughly ovular steering handle which allows a person with limited manual dexterity, such as from loss of motor coordination due to a stroke, to steer a mobility scooter with greater ease.

drive train - Typically, this term refers to the transaxle and motor when discussing electric scooters. Bear in mind, though, that some manufacturers will distinguish between the drive train and the motor for warranty purposes.

Electronic Speed Control - An electronic circuit that varies the speed of an electric motor, and sometimes is also configured to act as a dynamic brake.

EZ Reach Tiller™ - A steering tiller which is equipped with a lever which allows the tiller to be adjusted to suit the scooter driver's height and hand angle for safe operation.

frame - The main underlying structure of an automotive device such as a car or scooter. The wheels, motor, and body are all mounted to the frame, which must be strong enough to support the weight of the attached components.

LED lights - An abbreviation for light-emitting diode. Despite being brighter than incandescent light sources, LED lights use less energy and output less heat than incandescent lights, and can emit light over the visible, infrared, and ultraviolet wavelength spectrums.

LiquiCell™ equipped seats - Seats which are padded with a liquid-filled material which relieves pressure, friction, and discomfort while seated.

main circuit breaker - This component monitors the amount of current being drawn from the batteries when your electric scooter is in use. If the motors are heavily strained and drawing too much power, the main circuit breaker will trip, and your scooter will cease to function. This failsafe is intended to prevent damage to the scooter's electrical components from carrying too heavy a load or suffering an internal electrical malfunction which overamps the motor.

motor/electronics - Some scooter manufacturers offer warranty coverage on the motor and electronic components of the scooter, including electronic controllers and chargers. Bear in mind that this warranty coverage does not apply to batteries, motor brushes, or other disposable parts which experience normal wear and tear and must eventually be replaced due to use.

offboard battery charger - A charge station for a rechargeable battery which is not housed on the scooter that the battery powers. To use such a charger, the battery must be removed from the scooter and plugged into the charger.

onboard battery charger - A charger which is housed on the scooter, and usually permanently attached to be the battery, so that the battery can be recharged simply by plugging the charger into a wall outlet.

pneumatic tires - Traditional inflatable tires, much like you would use on your bicycle or automobile.

puncture proof tires - Also referred to as solid tires or flat-free tires, puncture proof tires are made of heavy plastic or solid rubber to protect against wear. Unlike pneumatic (inflatable) tires, puncture-proof tires won't go flat if a user runs over something sharp with their scooter.

tiller - A steering bar which is used to rotate the wheels left and right while driving a scooter. The term originates from nautical phraseology - tiller bars are often used to control directional rudders on boats.


General Maintenance Tips

Keep any pneumatic (inflatable) tires inflated to a pressure between 30-35 PSI. Not only is this best practice for your own safety, it will also extend the life of your scooter – under-inflated tires will cause a motor to burn out very quickly. Regularly inspect your scooter tires for wear; if the tread has worn down to less than 1/32 inch, they need to be replaced.


Check the battery terminals for corrosion and make sure that the battery is sitting flat in its well.


Regularly check all wiring connections and insulation. Frayed or otherwise damaged wires or cords need to be replaced immediately to avoid an electrical shock hazard.


Have a maintenance specialist check the motor brushes regularly for wear.


If you plan to discontinue using your scooter for an extended period of time, we recommend the following actions to prevent damage to the scooter: Fully charge the batteries prior to storage, and disconnect the batteries from the scooter. Store the scooter in a warm, dry environment – long-term exposure to extreme cold or heat can cause permanent damage to your scooter's motor and/or electrical systems.


Basic Troubleshooting for Electric Mobility Scooters

If all the systems on your scooter seem to be “dead” (i.e., no LED lights come on when you try to start it, or the scooter doesn't move when you accelerate), try the following solutions:

  • Make sure the key is in the “On” position.
  • Check the batteries to see if they are charged.
  • Push the main circuit breaker reset button (see your owner's manual for more information.)
  • Check that the battery harnesses are properly attached to the battery terminals.
  • Check the fuses on your scooter for burnout.


If the scooter does not move when you press the throttle, make sure that you have not activated a freewheel mode by throwing a lever, which cuts power to the motor and transaxle.


If the main circuit breaker is tripping repeatedly, or if you are noticing surges or hesitations when you accelerate, you may need to charge your batteries more frequently. If this does not resolve the problem, contact the manufacturer of your scooter; they can put you in touch with a certified technician who can test your battery's load. You can also purchase a load tester from a hardware store and perform this battery test yourself, if you prefer.


Obtaining Maintenance Service

Any new mobility scooter purchased through US Medical Supplies carries a 1 year in-home warranty which covers service calls to your home if you need maintenance or repair work performed on your electric scooter. We also offer extended coverage options out to two or three years for a nominal cost; we can increase the duration of our 1-year in-home warranty on full-size scooters to a coverage period of 2 years for just $109.00, or to 3 years of coverage for only $249.00. For travel scooters, the 2-year coverage costs $79.00 and the 3-year coverage costs $179.00. (Pricing subject to change.)


If your in-home coverage through US Medical Supplies has already lapsed and you require service or parts, you may still be covered by the warranty provided by the manufacturer of your mobility scooter. The manufacturer warranty which is included in the sale price often covers parts for a period longer than one year; however, you will be responsible for service call charges. It typically costs $75.00 just for a technician to come to your door. Warranties vary depending on the manufacturer and the scooter model you choose, so consult your owner's manual to determine the specifics of your warranty coverage.
