 Re: learn as you go
Well it took all afternoon but I got the bike wheel on the 350 motor. I had to take the controller off. The chain kept jumping off. After half dozen attempts I put the pusher up on blocks and found the problem. The motor wouldn't start at first I checked the controller and never could find the problem. I just took it and the throttle off. It is easier to just run it with an on off switch. I have some three ways on order so I'll put one of them on just to start it in a really bad situation.
I did it once today but I would feel better with it on a three way.
Now for the test results:
Higher speeds on the flats for sure. Better speed to bleed off on the hills means better pulling there. Not quite so much work to keep up on the incline. There seems to be a compromise on the range. It did a little better than the pure 450 with the bike wheel but not as well as it did with the small wheel.
My feeling now is that the bigger motor draws more amps and the range is decreased. But also the bigger wheel causes the motor to draw more amps as well. I think that when I get the 450 set up on the smaller wheel, it will draw about the same as the 350 on the larger wheel and the speed will be about the same as well. Which will give me two bikes
with similar performance.
To get really good performance I would need the bike wheel on a 700 watt motor at least. That would give me terrible range.
