Stop using cheap, run of the mill, standard type tyres then...They will not perform well except on regular bicycles that the usual speed is about 11 MPH...Yes i spend approx 50 dollars per wheel using Kevlar reinforced tires and ultra thick slime filled tubes...BUT ITS WORTH IT...never a flat in seven years and extremely long tire life since i started using them rather than the soft, cheap, crap rubber type, Chinese tires that come with them or the cheapy replacements that you can buy...Enough said...lol.Not many miles at all, probably because I do a lot of stop and start with the motor since it didn't hold idle but still...... it was ridiculous how quickly the tire wear out. I suppose a centrifugal clutch would solve the problem but, I'm not about to fork over money for that. I do like the center stand idea though.
Don't bet your life on cheap, crap, tires...good ones just might save your life.
