Johnmichael here, i love this scooter, however , the lever to fold the front half of the scooter is broken, the material used needs to be made a lot stronger due to the fact that the handle bar & it's assembly is constantly bobbing up & down i guess to make it more flexible. This silver looking lever on the left hand side needs replacing asap, where can i get a stringer replacement unit & how much would it cost? Last of all when i need new tires how much will it cost & where can i buy it, thank ...
