Inner city bicycles must be built so the cyclist can easily navigate the convoluted streets of even the busiest cities in the world. Otherwise, they’re going to get stuck somewhere and it completely defeats the purpose of having a bike. Designers in Michigan created the J. Ruiter to help city cyclists get around with as little effort as possible. There’s no frame, and the pedals are attached to the rear part of the wheel. In order to slow down, cyclists use the front disc brake. Even though this is a design we’re not really used to, it’s easy to learn and certainly impactful (Road.cc).
