Hello all, I did this build for a customer that already had a motorized bike. He wanted to add one to his garage that had more power to tow a trail-a-bike and so his wife could ride with him. This is what I built him, it pulls the trail-a-bike with plenty of extra power and on it's own is my favorite motorized bike I have built. I am going to build one for myself and add nice bars, tuck the cables and wiring, etc. Well any way here are a couple quick pics.
