Owning this bike ACT 104 since last 2 Years . Have got it repaired 15 times . All gear related problems. The back gear was changed twice. Once it failed while I was riding the bike & it jammed the back wheels & thus resulting in a nasty fall.
Had Chinese made tubes which do not get repaired once punctured & so you have to buy new tube when it gets punctured for the first time.
The design is so bad that even if one has to tighten all the nuts / screw you need more than 100 types of spanners.
As most Ordinary mechanics can not repair the bike Buy ONLY if you live near to a service station.
