I am looking for a brake tensioner that has broken and the chain broke. We have had countless wrecks and could use a rear fender to keep mud from flying up . But the bike has been very good. We had to replace 3 magneto because I made them wash it off when it was still hot. When you purchase them, no one want to tell you where to find parts or who will work on them. I bought them for my grandchildren and a guy from our church will do some work form learning experience for us, but I canĀ“t locate parts. I do not have a manual; only the title.
