I bought an Adly Thunderbike 150. So far, I´ve put 110 miles on it. The bike rides well. It´s comfortable. I haven´t throttled it all the way. The manual says to wait a certain number of miles before taking it up all the way. Adly has been in business for around 40 years in Taiwan. It seems like it is built fine. My only issue is the auto choke. I have to throttle it to start it. I can´t just press the start button to start it. Even after it´s been running. I´ll take it back in for an adjustment. The engine does seem to run well. The price seemed pretty reasonable for what I got. I won´t buy a Chinese scooter. I´m hearing too many bad things.
