I had my new build out today for a test drive. It's a ladies schwinn point beach cruiser with a Titan XC50 engine. I was surprised at how easily it started and the power and low noise are a bonus. I probably didn't have the rear sprocket properly centered and the chain got too loose. I really don't like the rubber/rag sprocket attachment so I just ordered the clamshell sprocket adapter from Livefastmotors that goes on the hub between the spokes. It's a bit pricey at 65.00 but if it solves my problem well worth it. Has anyone had any experience with this adapter?
