I've sent an email to Radpower EU asking if they will be introducing full throttle bikes in the UK with DVSA certification, these would still be classed as pedal assisted bikes with a minimum rider age of 14 no licence or insurance required and would be allowed on cycle paths, two UK manufacturers are already offering UK legal throttle wisper and Pedibal. 

It will be interesting to hear their reply!

My bike mechanic (who incidentally does tours on Rad Bikes!) made and fitted this rubber mud flap, it really stops surface water spraying into the controller area, I live in a very rainy area (Scotland) so this was a welcome add-on to my RadRunner.
