Electric Bicycle Mod Using an 36 volt, 1000watt motor to make an electric bike. I have questions about rpm and torque.
I have done some calculations, with wheels who have a 75inch circumference, i have calculated that 444 rpm should get me going about 40km/h or 25 mph. I don't believe that this is right. I am also wondering what amount of torque would be good enough for this situation?
The motor is 1000watts, 36volts and 3000rpm. I am planning to use three 12 volt car batteries to power the motor. I would be using a chain and gear transmission system to reduce the rpm.
I am looking to have a max speed of from 50 km/h or 31 mph to 40km/h or 25 mph.
I would really apretiate anyones help with this, so i could then finish this project.
