Edinburgh Bike COOP did some belt drive bikes.
I’ve got the single speed one with rim brakes.
OK bike I guess. Fork had mudguard eyelets but the frame was too tight at the back. You could fit road racers in though as long as 23mm tyres.
I find the handling a bit funny too – doesn’t feel too stable. Tried a fork with more rake and new tyres, didn’t make much difference.
Was called the Belter. They also did the Shadow with an 8 speed hub gear and hydraulic disks.
The Trek ones were called Sohos. Roller/hub brakes, hub gears, integrated mudguards and rack. I’ve been eyeing them up on eBay. They also did the District which is a more stripped down singlespeed
Belt drive is great btw – perfect for a commuter.
