I have over 5k into this 50. It has a 119cc engine with 4 speed tranny. Crazy fast. 2k red barron frame, $1500 Sano front suspension and a $400 Titanium exhaust. Has street tires mounted and also comes with dirt tires. Bike wheelies in every gear and has been clocked over 50mph. Sacrifice for $1800. I never ride it anymore and it just sits so it must go
