Hello, I have a question - my son is 170 cm tall at 11 years old and he would like a trampoline scooter.is it possible to attach the extension to the larger scooter 670?how much does the extension lengthen the handlebars?what do you advise?Thank you, Pickova
Good afternoon. This attachment is for scooters 570. Extend them to a height of 670. (It is the same length as the one in the original packaging 670) So maybe the best for you would be 750.
