carbon fibre wheels ok if no stones about.but if you were riding rocks wouldn't last five minutes

Can't see those wheels/swingarm or belt drive would last 1 lap of a trial in Yorkshire :hyper:

Interesting, but it does look rather like a capability excercise. I like to see people try new things, but I can see many more reasons to not persue this particular direction than I can to do so.

Looking at the (very tidy) early gasser's back tyre, it doesn't look like these bikes are regularly competed! Certainly, eastern mud would stop the gasser for grip, and the Mont for swingarm clearance, never mind once the belt dragged it onto the pulleys!

Like the master cylinders though...

You see that driveway..that one, there, with all the pebbles?...belt drives hate that 5h1t.

You see that weight-saving flat tank?..me neither.

I applaud the sentiment,not the execution.

That's one really confused engineering project :dunce:

Yep, to start a development, you first need a set of requirements. Not too sure exactly what those would have been!

Nice project,but pointless as a practical bike.How long would the spokes last when they are on the outside of the rims,and a stone caught up in the belt drive would soon wreck that
