I have a few ideas to the rim
To make it stronger weld in a H bar round in the rim
the advantage is a stronger rim and the gear hub can be placed higher
some other ideas possibly with rubber ball bearings in the h bar and the gear hub like a roller coaster
possibly 4 hinges on the h bar to the rim to be able to fold flat
and maybe some inches of medium hard rubber zo you never get a flat tire
I have no more ideas but I am very interested in the development of this bicycle greetings Anton Heidebrink at.heidebrink@gmail.com
]]>Also, the drivetrain looks extremely close to the ground at the rear. How far can you lean the bike without scraping the drivetrain along the floor? Considering the way all bikes turn, that is an element that really needs to be looked at.
Overall I do like the design but there are a huge number of possible failure points in this model. If the designer would take advice, I’d say give the prototype to a cycle courier for a month and see how long it lasts, and the condition it’s in when it’s returned 🙂

]]>You got some valid points listed. But let’s remember this is the first prototype. Nevertheless, such valid points are always helpful in any design process
