Whatever that means
Although not a new one. One that I built a few months ago as a single speed and then didn’t actually use. I’ve stolen some bits and pieces from other bikes, especially the old mountain bike that I’ve been using to haul Ellen’s trailer/tagalong, built some new wheels on hubs with brakes, gears and a dynamo built in, put some fatter tyres on it and made it the replacement for the mountain bike. A very satisfying way to spend a dreich day.
