Backtracking, New Pipes, and Better Ideas I had to do a bunch of backtracking. I had to make the things that connect the wheels to the frame equal so that they could work, removed all of the fillets since they got in the way when I was fixing things. The main problem was how I was going to steer the wheels with the legs. Ideas: The first idea was using a rack and pinion. Connecting it by putting another on the other side of the gear. But I figured to go simple and turn the pedaling mechanism to its side. Currently, I made the two pipes, one for the front wheel and the other for the height of the bicycle seat. Another problem that I fixed is the size for the gear when you pedal, so I had to shorten the back length.
