OK, SoCal old guy here. Been building Harleys and cars for decades and now my adult son and I are playing with motorized bicycles. Did one to see how they ride, building a second for my son to use as a daily rider. Also have a project bike that will have a vintage feel but that's going to take some time and fabrication. Here's a shot of the first one we did. Pretty basic but with a 49cc it hauls my rather large 280 pound butt down the road at 30 MPH+ with no problem.
That's all for now. Thanks for reading.
