The single worst thing about riding a motorbike is the cold, cold winters, sitting at the traffic lights looking at everyone signing away in their warm cars. It’s near impossible to look cool when you’re shivering. Who has it tougher than those cool bike riders? Delivery men and women who drive for hours on end in the harsh winter conditions.

Byeongjun Kim has designed a simple yet effective solution to those cold winter journeys – the B-HEAT. This is a hot air fan for motorcycles that recycles exhausted engine heat. While riding, B-HEAT self-generates and saves electricity by upwind, and while waiting for a signal, it sucks and conveys heat up to the driver. With the simple twist of the outside tubing, the user can determine the speed at which they deliver the hot air up to the body.

The B-HEAT isn’t made for every bike though, designed for the Underbone – one of the styles of motorcycles that uses structural tube framing with an overlay of plastic or non- structural body panels, and are most popular in Asia, particularly in Southeast Asia, Middle East, India, Taiwan and China for both daily-life and business purposes. In Underbone, the engine is located under the main body frame, between drivers’ feet, so that there are holes for maintenance on the front faring. Using these hole, B-HEAT fit on almost every Underbone bike and no tools are needed for installation.
