They are just awesome commute bikes. They are the bikes you can throw around. Leave locked up in the centre of town. Perform minimal maintenance and they just keep on going.
The single speed I’m riding is fun to ride, being able to just ride along, not having to think about gear changes, just keep those cranks turning. It’s quiet (well now I’ve sorted the clicking, maintenance is stupidly easy and quick.
Maintenances on the bikes are pretty easy, with not having any complex derailleur’s, you just need to check the basics before riding, and basic maintenance at intervals.
