Hey guys, my son has been wanting a 50 for a while now and I figured I'd get him one for Christmas. I found one on Craigslist for pretty cheap with the title so I decided to pick it up. It needs quite a bit of work but does run really well. Anyways,to my question. The front wheel has no brake on it at all. Missing the handle/cable also. What do I need to get a front brake on this? I have attached a pic to show you what I'm working with. I'll have a lot more questions soon, figured I would start with this issue first. Any help is appreciated. Thanks.
