Electric Bike Conversion Kits

sunstar electric bike kit Electric Bike Conversion KitsIf you’re intending to electrify a favourite bike, an electric bike conversion kit might be the answer for you. Electric bike conversion kits usually include a replacement front wheel fitted with a motorised hub. They are available from a wide range of manufacturers at a wide range of prices, from £300 to well over £1,000. Kits vary in quality a great deal too. The cheapest tend to be unbranded Chinese or Indian products… OK for leisure use, but with limited warranties and back-up, so don’t expect to use this sort of thing for daily commuting! More expensive electric bike kits are usually kit versions of proprietary electric bikes sold by manufacturers such as Izip (sometimes misspelt E zip or Ezip), Currie (sometimes known as the Curry), Heinzmann, Ezee and BionX.


  • Some electric conversion kit prices include fitting, others do not.
  • Most electric bike kits are supplied with UK-legal 250w motors, but many use motors of 500w, and a few are rated as high as 1000w. Remember that these powerful high-speed conversion kits are not legal in the UK and the fact that you are riding a machine powered by an electric bike conversion kit will make no difference in the eyes of the law!

The comments relate to our own experience with manufacturers or distributors. As a general rule, a company that supplies a good product can afford to be open and helpful with the press, and will give good service and back-up. The others are something of an unknown quantity, but if you think we’ve been unfair, do let us know. For a global list go to Electric Bike Manufacturers Worldwide
