The very same thought was lingering in my mind for some time. I purchased this scooter 3 months back and whenever I take it out, I feel slight pain in my back. I thought it will be due to highspeed pass over humps. But recently my friend(using scooter for 2 years) also complaint that eversince he started using this scooter, he developed severe back pain and finally decided to stop using it and walk all way to office(3 kms!) .Now I too feel it is creating back problem for people who are above 5 8’.may be defective seat - handle geometry?
Also I am facing balancing problem on the scooter on mild turns itself.felt the back wheel going out of arc.I never had an accident. Air pressure is also checked. No extra luggage.Single riding and wheel balancing also done. Still I am facing this issue.Don’t know whether any body else felt it.
