Having researched electric bikes for some months I recently had a break at Center Parcs and was able to hire one - a Raleigh Motec. This was my first experience on an electric bike and it was impressive. Bosch power which was remarkably quiet. Next steps was to call at 50 Cycles Bristol on the way home and choose between a Kalkhoff Include belt or Kalkhoff Integrale 8 Belt. I bought the Integrale and its just incredible. I have a very steep hill near my home and the bike just flew up it - amazing. I also like the fact that you actually do get a workout on these bikes using the various assist levels. Design wise its a real head turner and many cannot believe its an electric bike. Great decision - all still new and look forward to adding an update in due course. Oh and the Integrale has some sort of sat nav. which I don't intend to use.
