To diagnose an electrical problem with your broken electric scooter or bike, start here. After isolating your problem, you'll know whether you can fix it yourself or want some repair shop to fix it. If you need parts to repair it yourself, get them from a parts retailer. Your local LEV retailer may have what you need. If not, check our list of on-line parts retailers.

Introduction

Most electric bikes and scooters include four primary parts: the battery pack, the motor, the throttle and the controller. The controller stands "between" the throttle and the motor and controls the motor. On small, low-power drive systems, a simple on/off switch or relay may be the only controller. But for systems using motors rated above 250 watts, a controller generally limits how quickly the motor accelerates and its maximum speed. Currie sets the controllers on all its motors (300, 350, 400, and 600 watts) to limit the LEV maximum speed to 16 mph.

If you don't have a VOM, get one. A Volt-Ohm Meter (or multimeter) is essential if you'll be living with an LEV.

Fixing the Problem

Most people - with a few tools and the right replacement parts - can fix their LEV power system. If you're willing and have diagnosed the problem, find the parts you need at your local LEV retailer. Or check our list of on-line parts retailers. If you prefer someone else to fix your ride, your local LEV retailer may do repairs. Many local retailers offer service of the brands they carry - and others. If not, check our list of quality repair shops; remember, though, that shipping can be expensive. Other shops that understand and work on electric-powered devices include sew/vacuum shops, automobile electric shops and electric wheelchairs shops. Here are some common procedures:

  • replacing batteries
  • replacing belts or chains
  • replacing throttle
  • fixing flats
  • replace the fuse
  • replacing the motor
  • replacing the controller
