During the minor All-round Design I had the task of making a redesign for a startup company called Boppe Bike. They bought a big amount of parts in a bankruptcy auction and wanted to start making cool bikes out of them. To make this bike something really special, I also designed a differential which makes it possible to influence the speed of each front-wheel. This, combined with the caster wheel in the back, makes for a very well maneuverable bicycle.
The differential works by reading the input speed of the driveshaft (which comes from a Bosch e-bike motor), and making the electrical engine rotate at the same speed. If you steer the bike, the electrical engine will rotate more or less quick, making one of the front wheels rotate faster than the other. This makes the bike turn, since it has a caster wheel in the back.
