I tried to see if it brakes like a modern bicycle and it does seem to..rear wheel is so warped hard to tell for sure as it won’t spin much before dragging. Looks like serial number is 005607. I measured the down post and it came out at 21 inches. They were suppose to be either 20 or 22 inch models so I don’t know what it is being in the middle of those 2 numbers. Yes I discovered front wheel is incorrect. Thanks
