Store Polices | Electric Scooter Repair Help | Dealer Discounts | Feedback | About Us

At Electric Scooter Parts we have been providing electric scooter troubleshooting help to our customers for nearly two decades. We build and repair our own electric scooters and bikes, and we have helped thousands of people troubleshoot and repair their electric scooters and bicycles. Through our hands-on and customer service experience we have learned what the most common electric scooter problems are, and how to test, diagnose, and repair them. We have compiled our knowledge into this online electric scooter troubleshooting guide.  Although we may not mention electric bicycles on every page of this troubleshooting guide, electric scooters and electric bicycles share the same electrical components so troubleshooting methods are usually the same.
