Adjustable footpegs are far from a new idea but even on motorcycles that have them the adjustment process normally involves wrenches and hex keys. So a new patent application from BMW showing pegs that can be moved in seconds without any tools is interesting in itself. But the idea has specifically come about thanks to the company’s development of electric bikes—adding to a growing file of evidence that a BMW EV motorcycle is getting close.

The system illustrated in the new patent is incredibly simple—the sort of thing that makes you wonder why it hasn’t been done already. It shows riders’ footpegs that are mounted in a slotted carrier that allows them to slide, but there’s no need to loosen bolts to move them. Instead there’s a sawtooth patterned set of notches machined into the aluminum hanger below the adjustment slot and a stud that extends inward, directly opposite the peg itself, to fit into it. The peg itself is hinged like those on most bikes. When the peg is extended into its normal position, the stud opposite it locks into one of the notches, preventing it from sliding along the slot in the carrier. To adjust the peg, you simply fold it upward, disengaging that stud from the notches so the whole unit can slide along its adjustment slot.

BMW’s patent explains that the slot could be straight or curved, and in a variety of directions depending on the bike the system is fitted to. On a sportbike, for instance, it might slide backward and upward for track use, and forward and downward when you want a more relaxed riding position.
