Don't trust the web pages 100%.by transposon » Mar 21 2020 11:35pm
Thanks for the input everyone. I think I am going to get the 1500W version in order to be able to pull some cargo. In order to get up and running, I think I am going to get one of the kits. I am confused on the top speeds listed for the kits. I assume they are are dependent on the winding, but of 2 kits with presumably the same motor, I am seeing different speeds listed.

This one has speeds of 45.2, 35, 25, 15 mph.

This one lists 42, 37.5, 30, 25, 20, 15 mph.
I am confused how presumably the same motor has different speeds depending on the kit purchased. Also, any recommendations for a setup that is good for an average of 20-22mph with the capability of ~30mph thrill rides once in a while? I plan on building a 14S battery.
Go to https://www.ebikes.ca/tools/simulator.h ... heel=27.5i
figure out what battery can do what you want then get a little more if possible.
Leafbike will change the winding of the leafmotor (blackmagic) to alter the speed of the motor.
Add in the wheel size you plan on running.
Play with the MOTOR SIMULATOR it will be close if not on the money so trust it.
I decided to get the 7T and it does what I wanted. Now I want a 6T.
I use a 72V 25AH battery with a 80 amp bms but have it limited to continuous amps, 36 amps. here a link to my setup.

If you compare the two links the speeds are close to the same. But they get there differently.
