Thanks for the Kind remarks Black Dog, the 905Classic is a very special bike. The power is slightly stronger on each setting. We leave the maximum power on for more and more time on each setting to help you get to higher speeds at max power.
It's nice to know that Wisper are doing something, but I must say that I haven't seen many Chinese bikes with torque sensors. Torque sensors have the potential for faster response times, which to me is their only advantage. It's what you do with the sensor that makes the difference. The algorithms are in the control, not the sensor. It sounds like you're doing something sensible. I can't understand this obsession with trying to make an electric bike like a normal bike so that you get no power when your legs are tired. I think that a lot of the designers are cyclists, not people like us. There must always be some way to get maximum power without stressing yourself to maximum. By all means have a torque multiplication system but then you need another control that can turn up the power when you're tired.
I agree completely. That's why I don't want a torque sensor. There's nothing to beat getting to the top of a long hill then be able to relax with little work whilst the bike does it's own thing.
Of course you need to be able to turn the power down when you want as well for the times that you feel energetic.
Aye and some days I seldom see power level 5 except on the steep hills. Other days I only ever see power level 5.
It's true that Panasonic were using torque sensing very early on e-bikes, and they actually started life as a bicycle manufacturer long before getting into electronics. They still are one of Japan's largest bicycle manufacturers. The founder of the company, Konosuke Matsushita grew up with a family who owned a bicycle shop and always had a love of bicycles and cycling, so I daresay that influence is still strong, given the Japanese love of tradition.
I have always made this point. I disconnected my pedalec and only use the throttle. This gives me an infinite range of power between nil and the maximum the bike can give, at any time, and none of this 'surging' that I have never experienced.
I'm not sure I'd ever want a 'proper' bike again where I live. It was far too much like hard work the last time I had one here with all the steep hills; and I wasn't past retirement age then either. I was pretty fit from running with the dog then too.
Or as George Bernard Shaw wrote:
I can't agree with this. I already had an ordinary bike (in fact, I had two, one of them a very nice Dawes Galaxy), but I wasn't using them. It's hilly round here, and work is just that bit too far away to make a commute feasible. If I were young and fit, no problem, but I am neither of those things. I need the exercise, but there are psychological and physical barriers to using the pushbike regularly. However, I managed to commute to work and back yesterday and felt I had a good workout on the electric bike. Yes, it was probably only 50% of the exercise I would have had on a 'proper' bike, but it was 100% more than I would have had without it.
