didn't really keep track of the time here. The chain broke and tore off the rear derailler and mangled the front one. Decided to make it more like the high end bikes. Looked at how one guy did his with parts from TerraCycle, expensive, so I bought parts from TerraTrikes and machined the aluminum bracket from .5" 6061-T6 to hold the idlers. Ordered two standard idlers and two Deluxe 13 Tooth Idlers.
Went to Metrics Unlimited and bought 4 long 8mm socket head screws. Went to Metal Mart and got some steel and aluminum scraps and started to design.
The steel steering link has broken twice in handling the bike so I made one out of aluminum tube with solid drilled and taped ends riveted into the tube.
