11t and 16t sprocket bike is 45lbs less on weight so total of 220 lbs versus
300+ i had
didnt ride it with full throtle but half when it started smoking
the motor will run under load for couple of seconds before it shuts, then throtle again it runs and shuts
remember i had 44 t sprocket when same thing happened, now i have 16t
so i cant see anything other then controller being just underdeveloped for what it is ment to run correct?
AFAICT, you've made the problem of gearing MUCH worse, rather than better. If I didnt' miss anything in my going back now, looking at your thread, I don't think you understood my posts describing and showing the math for the gearing and wheel speed vs motor RPM. If I did miss something, and you understood and have compensated for the gearing change, I apologize.
But it looks to me like you needed to put a *larger* sprocket on the wheel, not a smaller one. Smaller will make the wheel go faster, placing a much greater load on the motor, forcing the motor to turn even slower than ti did before, when it smoked becuase the gearing was insufficient.
If the new motor's RPM at the specified voltage is lower than the first one, down to the RPM the first motor was actually running at, then you coudl probably have gone with the original sprocket to make it work. But if the new motor's RPM at the specified voltage is the same, or higher, you'd need a larger sprocket to do the work, just like before. As I described before, you have to figure out the motor's RPM at the voltage you're going to feed it, and then provide gearing that lets it run somewhere up near that when you're at the speed you want to be riding at.
I'm sorry that I have been unable to read all of hte posts in your thread each time I have had a moment to drop in, or I might have seen where you were planning an even smaller sprocket and tried to steer you back to a much larger one as I tried to point out in my first post on that subject, where I showed you the path of math to see what hte motor RPM was.
