It’s no Cosmos Charger, but this custom-built, split-wheel Honda CBR 250R is the world’s first. Sketching this project out is one thing, building it took more effort than expected, as Sean Kerr of ‘Bikes and Beards’ first had to extend the bike’s swingarm before a second rear-drive wheel could be fitted.
Then they had to deal with installing a secondary wheel with sprockets placed on the other side, which meant the team ended up with two sprockets on two wheels, with two chains. One of them was being driven by the wheel, while the other powered the secondary wheel. As for the tires, they sliced them in two and tried filling them with spray foam, but that didn’t quite work, so rubber mulch-stuffed pipes were added instead for rigidity. Unfortunately (or fortunately), they were only able to achieve a top speed of 30 mph.
