The outer tire pops easily in place thanks to the spring setup on the upper suspension, the idler wheels also maintain a tight grip on the inner rim while allowing the drive wheel to rotate quite smoothly!
A shot showing the twin suspension viewed from below, here you can see the spring supports. They are glued to the right side of the crescent and attached to the left side via two bolts.
The frame is completed!!! Now all that is left to do is make the battery/rider support and install the electronics!
