hd axle

My first Beach Cruiser build, just waiting on the pull start to arrive. I tried out the new cordless drill starting option, it works, but it sucks because if this is how you want to start it up, you have to lug around a drill! Which is ridiculous. Also the little flip cover over the crank gear...
