The Bicymple is a bike without a chain that is connected by a straight frame, and can be steered from the rear or the front, perfect for riders making tight turns and twists.

The bicymple is a concept bicycle design developed by Washington-based studio Scalyfish Designs that hopes to evolve the standard bike while adhering to the basic principles of simplicity, functionality, and excitement. Core77 reports that it has a rear-steering option for tight turns and “crab riding.”

The chain has been removed, reducing the number of moving parts and the overall complexity. A direct-drive, freewheeling hub joins the crank arm axis with the rear-wheel axis, shortening the wheelbase and minimizing the design. The lightweight and stylish bike is described as “comfortable, easy to ride, and brilliantly simple to maintain.” Its ultra-compact design enables the rider to get it in and out of tight spaces like stairwells, hallways, and fire escapes.
