Bicycle

I bought a used ebike purely for the experience of upgrading it.

I stared with a Electra Voy bike/scooter which I found on Craigslist and boght for $150. It has a 36V lead acid battery set which feed a 180W hub motor.
My ultimate goal (and I have all ready ordered parts) is to upgrade it to a 48V, 1000W, LiFePo4 system with regen breaking.
I ordered the motor and controller (with regen breaking) from "Golden Motor" ($400), and the LiFePo4 battery with Battery Management System from a Chinese distributor through ebay($400).
