I didn’t give you guys, 5 star review, The Gt20 I purchased the bike 2 years an 1/2 great. Bike never a problem good looking a lot of people give me great compliments make you feel good, the only reason, my bike torn off two weeks ago, I went to six repair shops no one wanted to help me , if anyone would no were In New York City, that I could fix my bike.
