I´ve had my Thunderbike 150 for a little over a month. I like it so far. I have 340km on it. I just changed the oil for the first time. I´ll change the gear oil this weekend. I also took the stripping off of it. It made it look like a toy. The one issue I have is that I have to throttle it to start it. I mean that I have to turn the throttle a little ways and press the start button. Is that the same for other people? It runs well. It has plenty of power. I´m 6´2\
