FirstBike lowering kit
thingiverse
FirstBike lowering kit. If you kid's feet don't reach the ground, this kit lowers the bike further so they can start cycling at a younger age. I made this because the original set from FirstBike broke after a short while. Requires 2x M8x16 bolts, washers and loc-nuts like the original set from FirstBike. The kit could be designed not to require these, i suppose. I printed my wall and top/bottom 2mm thick and 30% infill, with support. That's 5 walls x 0.4 nozzle and 10 layers at 0.2 layer-height.
