Carve the tires out of the same material that you cut the racer frame. We kept these as a clean 3 spoke design, but you could add more or less detail to the spokes. You can also add grip to the outside or experiment with the size to get better results.

For the axles we used 3mm rod that we cut to length. For the rear axle you can take a short piece and epoxy it in the center to create your catch for the rubber band.

The wheel wells we made using small hex nuts that we super-glued in place.

Once your bottom frame is all set up you can adhere the top piece and tires, Then you are ready to ride!
