prototype veer shift 2-speed cassette for belt drive bikes Belt drives are quiet, clean, and simple, but rely on internally geared hubs or transmission boxes to add more speeds to a bike. Now, Veer is working on a unique two-speed cassette that uses rotating tooth sections to change the ratio without changing the belt’s alignment.

Veer makes belt drives to compete with Gates, etc. Called Veer Shift, they’re looking to take it a step further by giving folks a chance to invest ( on StartEngine ) and bring this multi-speed design to market.

It works by placing six rotating segments on a freewheel. Each segment has two gear ratios, one with four teeth and one with seven, though it looks like not all teeth are engaged so it’s really about changing the effective diameter.

A tensioner (that looks like a derailleur) is there to allow the required belt length while taking up the slack. Here’s a video showing it in action: Basically, the segments rotate as the belt comes off of them. By the time they roll around to the bottom to make contact with the belt again, they’ve switched sides and changed the effective diameter. Nothing moves under the belt, and the belt doesn’t move left or right. The functionality is quite ingenious, but…

Veer says it’s far more efficient than gear boxes and cleaner/quieter than chains and cassettes and derailleurs. But it does beg the question, why not just use an internally geared rear hub and gain up to 14 speeds […]
