I haven´t looked into a way to change it from KM to Miles. I have seen discussions about it on other sites. I didn´t see any answers. Since the manuals maintenance is in km. I´d rather leave it as is. I´ll check out other forums and try to get Adly riders to come onto this site. I haven´t seen any Adly riders in my part of town. The Adly does have a lot of zip. My girlfriend and I rode it at the same time. Together we weigh 330lbs. The scooter caried us without and problems. We never rode up any steep hills though. The manual says 1000km and 300km. Must be a typo. Since you spoke to the Warranty Manager and they said before 1000km, i´ll wait a while longer. The scooter calls for 85W90. I couldn´t find it at an auto parts store. I´ll call a local scooter store and see if they carry it. So far, I´m happy with the scooter. It´s getting over 80mpg. It´s nice too see a lot more people with scooters around town. Hopefully, drivers will be more careful.
