But I'm really charmed by this new detachable electric drive which has been looking for funding on Kickstarter (they've now hit their £63,000 target!).
|The Rubbee Electric Drive for Bicycles|
It's beautiful, simple and really clever. It weighs 14 lb (6.5 kg), ihas a range of around 15 miles and can get the bike up to a top speed of 15 mph. It's also easily removable and re-chargeable and will fit on most bikes. What's not to like?!
Even Sir Richard Branson is impressed...
Good luck, chaps!
