I have a cyclone 3000watt 24-72v motor that i customize on a bicycle frame. I am currently running it on 24v. The current gear ratio setup that i have gives me a lot of torque to climb the steepest hills you can find. I can even stop on a steep hill and move off.
The issue that i have is that its very slow on a flat terrain at 24v and even when i upgrade to 48v there's just a slight improvement on the speed but the torque power is greatly improve as you would have guess.
What i need is a good balance between speed and torque at 24v. I want to travel at a relative good speed when i am on a flat terrain and still can climb hills. Currently the speed on a flat terrain now is around 10-15km per hour which is very slow.
Please give me some suggestions as to what size sprocket i should use on the motor shaft and also on the rear. I currently have a 14t cog on the motor and the rear sprocket is 28T.
Below is my setup.
The idle is there just to prevent the chain from touching the frame. If I need more tension on the chain to getter better chain wrap I can adjust the motor bracket by pulling it forward.
Thanks for info.
I am thinking of using 28t on the motor and 32t or 34t at the back. Is that a good balance between speed and torque? The teeth options that I have to use on both motor and rear are : 28, 32, 34, 38, 42.
What do you suggest I do?
