HarryB, I was very interested in your comments, as I've short listed the BH E-Motion Sport Max + for riding the 7 miles back and forth to work on the flat (and for leisure). Its the only range of electric bikes that I could find that look like a normal bike. I live in a 2nd floor flat, so whatever I get has to get lifted up and down four flights of stairs every morning/evening therefore weight is high on my priority. I also want something that is light enough to ride unassisted.
Up until now BH's E-motion bikes all used the Panasonic crank drive system, however you say you would probably buy a hub drive bike if you had to choose again? So its interesting that BH appear to have launched a new range of rear Hub driven bikes with a Samsung battery moulded into the frame, I dunno if this is done for cost reasons or whether BH are having a rethink?

I'd steered away from Hub driven due to less flexability in using the gearing, and the complications of removing the rear wheel in the event of a puncture. Anyway, your experience is interesting.
