The Transport bike has a storage compartment in the front wheel to store your bag and water bottle. Good idea? The front wheel is too heavy while you fill it with your stuffs? To make the storage compartment using PET-G, vacuum-formed over a sign foam mold and the hubless wheel rotates around a system of six bearings. Transport bike weights around 25 lbs, creators claim that's about as heavy as your average road bike. "Transport" is a commuter bike design project sponsored by SRAM.
