Turned the Ezip 400 into a petrol scooter. Needless to say, it's now hitting 37mph and the tires didn't last long. Found these tubular tires. Backup and start without problems.
Good quality, more than I need for portable generator tires but great value for the set. I had to tighten the split hubs together with jackscrews until the bearings snapped easily. They are of good quality.
