Does anyone have any experience of the motor kits supplied via eBay by cammy_cc, eg Electric bicycle kit 24V 250W E-BIKE RETROFIT KITS New on eBay, also Electric Scooters, Scooters, Outdoor Sports, Sporting Goods (end time 06-Jun-09 05:52:49 BST)

A search suggests that some may have bought his Lefepo4 batteries but nothing else.

That seems incredibly cheap - though I don't see a battery in the package, interesting though, as I'm starting to concider a kit for a little used recumbent...

The low price interests me too, but note the postage: surface mail 5 to 7 weeks, around £70, airmail services, 5 to 14 days or so, around £120.

Vat, duty and clearance fees may have to be added, and of course there is no battery although his LefePo4s are comparatively cheap, but carriage, insurance, and duty etc may all have to be added to these too.

They are almost certainly direct drive motors (motor running at wheel speed), so in this low voltage form will be low powered and have very poor low speed torque for hill climbing.

This type of motor is best suited to use on higher voltages and powers in the US performance market and that site offers motors in those forms. The internally geared motors like those on Wisper, eZee and Nano powered bikes are better for most of our territory and usage, having more hill climb ability and better economy.

On the plus side, direct drive is simple, cheap and quiet.

Thanks flecc, I think I shall stick with the brushless Suzhou Bafang which comes with the Alien Ocean kit, with no worries about high postal charges, or VAT, duty etc, not to mention the return postage cost if any of the kit proves defective.
