Well built..Good break precision

I am 5.5 ft , It suites right for my height. Its is smooth, Bell is not good & not enough for city rides. Had to get Mud guard fitted as still water spills on rider.

Just awesome bike for city commuting

Pros: Goood build quality Light weight Good parts used(Suntour Shocks, Shimano Tourney drive train, Aluminum frame) Seller provided an bell, thats cool..!! Good for city commuting. Cons: Do not come with Double walled alloy rims, due to that one can do extreme offroading. I higly recommend the bike if you are not into extreme sports.!!
