Here is my home built vintage electric bicycle using a xiongda 36v 250w motor and McAllister 36v 4ah batteries.The frame build started when I poped in to Valley scooters in Bolton ( my local ebike shop ).I wanted to see if he had any used battery boxes,I might be able to use for a battery pack I was planing on making.He had one and would take no money for it.I showed him my first homebuild a mountain bike with a frame bag 2 lawn mower batteries and a solar tracker motor that I got off eBay.He said he used to sell them and could not believe the motor was still going.He then said so you like projects you can have this.I was now the proud owner of a Monanna e power girls shoper bike with no batteries and a dead controller.
