I hit a pot-hole, while on my Emmo GT80 scooter, the other day. The tire went completely flat, and the rim was bent. Since the motor is built into the rear wheel,on this model,the whole thing would have needed to be replaced. Ron took a mallet and straightened the rim, so that it would allow for a good seal the tire - saving me $300.00! These guys always surpass my expectations! Thanks again!
