I purchased a Z20 Electric Scooter at some point in 2007 and didn't receive it until January of 2008. It definitely wasn't what was advertised. The speedometer read about 10mph fast, so it didn't go as fast as EVT America claimed it would. I tried to contact customer service about the possibility of adjusting the headlights and received no response.
About April, when the outside temperature started heating up, the controller would overheat and the Scooter was useless. I ended up selling the batteries for the core charge and junking the rest of it. These Scooters are no more than toys, made in China, that shouldn't be taken past the end of the driveway. Don't buy anything from EVT America. I can't believe they are operating under the same name.
