I am having a Americanspeedster Sidekick 4 wheel bike assembled for me. This PVC bile uses 20 inch wheels. Originally they offered a Sparrow motor for it. I started to order the Sparrow and was told that it was a brush motor and they now offer a better motor. He wanted to know if i want the 36 volt motor or the 48 volt motor.
My limited knowledge of electricity makes me think i want the 48 volt motor for more torque. Am i right? Is there a lesson on batteries i need to learn. Such as does the 48 volt have an exhorbriant price etc?
Any education gladly appreciated.
Thanks for looking.
