Hi RobF - good point. Its just that the test ride I had was on the 52cm and thought that was right for me and I can't test the 55cm as it wasn't available. I never looked at the different wheel sizes. What about Bosch v Yamaha - any thoughts?
I've only had a brief go on the Yamaha, so am unable to make a valid comparison.
I like the refined and easy to live with nature of the Bosch.
Mine has been ridden by a couple of bike dealers who had previously only tried hub bikes.
Both commented along the lines of "That Bosch is what an ebike should be like."
From what I can gather, the Yamaha is similar in that respect.
The Yamaha is supposed to have a bit more poke, but that wouldn't be an attraction to me because I rarely use full power on the Bosch.
Quite the reverse, I ride at low assistance levels, partly to get distance from the battery.
The Yamaha has only three assistance levels, that would concern me a little in terms of fine tuning the assistance to achieve the most miles.
There is also an impact on speed, I naturally ride faster in 'sport' than 'tour'.
So it's rather like gears, the more ratios you have the better - within reason.
Four modes on the Bosch is about right, although I sometimes wish I had another between tour and sport.
