I live in Florida on the west side of the intercoastal waterway. The best rides are on the east side along the beaches. There are high arching bridges to get from one side to another. I am 68 and 240 pounds. I need a bike that can do the bridges in pedal mode. I would prefer a Bafang mid drive so I have full use of the gearing. And live on a apartment upper floor with a small elevator and am limited to 72" inches total length. I had to return a Eunorau G20 due to bad information on total length. I have been riding e bikes for over ten years all with bafang kits the current one a 1000w HD. But it is getting tired with about 10,000 miles. And would like to try a shop built bike. Any suggestions people?
