I am looking to build a few three-wheeled electric scooters. Would you be able to help me with a parts list?
Specifically, the first scooter will have two ≈6" in-hub motor wheels in the back and one ≈8" fixed pneumatic wheel in the front. The steering would be done by the motorized wheels, similar to steering on the "hover boards." Ideally, the wheels would be able to spin relatively freely so that the scooter can be used as a plain kick-scooter as well.
I already have a system that has proven powerful enough for me with a Turnigy Aerodrive SK3 out runner motor and a 4S 14.8V 5000MAH 30C Battery. I would like to replicate this kind of power with the in-hub motors.
I would like to pick up as much of a set of materials as possible in one go: motor wheels, controller(s), battery Pack, charger, rear axle, throttle(s) or alternate, pneumatic front wheel, handlebars, standing board, ...
Weight is important to me but price is not.
I am close to San Jose and could happily come by to look at pieces and talk through tradeoffs with someone live.
Do you have any controllers that could work with low voltage? (I couldn't find any on the site.) If not, any way to disable the under voltage protection? If not that either, any other ideas?
Thanks much for the reply.
>easier to switch over to a 36 Volt battery pack
That is what I ended up doing.
For the benefit of others on the forum interested in 36V battery packs,... FYI, I wanted Li-Ion batteries and wasn't having much luck finding a 36V pack. I was, however, able to find 3 packs of 18650 cells each at 11.1 nominally (Tenergy Item #31013). I put three in a series to get a nominal 33.3V. The actual voltage goes to about 38V and below 30V which is good enough for the controller and motor.
We'll see how it goes...
