Its a fairly rough solution to a problem I am not sure exists but also quite cool in a just because you can kind of way.

It’s a good effort, there are more polished versions around though – these guys have been doing it for years, but it’s never really taken off in a massive way: https://christinibicycles.com/

That’s pretty cool! Yamaha did a similar thing BITD 🚑 🏥 –

and I think there’s a more recent hydraulic version on one of their 4t bikes too.

with no diff isn’t that going to cause all sorts of wierdness on tighter corners (or, in fact, over any bump)?
