early bug flea they used 3/4 tubing 1" on the forks and 6" wheels 50# engine looks like they broke a lot.....the jackshaft mounted disk brake i used an airheart mechanical caliper there is a cheaper copy dont panic on the arm position you can take it apart and change it.....the disk creates a problem i was lucky to find 5" disks but they run a 3/4 shaft you could do that but it looks huge so i ran a reducer and a 3/16; X 1/4 key this takes time and fitting trial and error.....i found a serial # on the engine plate.....I do like the seat mount engine plate....they did run the chain and sprockets on the left side hope it had a chain guard
