Cargo Bikes

As he wants to be able to change rear wheel without an insane level of effort to remove a through axle. The folding one looks like you could strap all sorts to it. Opens possibility of getting a cardboard box of something home on each side of bike, sat on the step with a strap around it.
The black add on feet things that block the axle look like a mistake to me. Frame already has foot rack, or get jumbo folding rack
