agreed with ettige
i do treat all my bike like owning a ferari

i always make sure my bike are shining and clean after ride.my wife always angry at me if i ride on rain (or after rain), coz i always spend minimum 3 hours to clean my bike! very sayang lor....
for what i can see,the average max weight for any folding bike to handle is 110kg +-,but to play safe please ensure u are weight around 100kg below.most europian weight more than that.
1 more factor i see that some people like to cycle in light gear to get more cadence.hence the more cadence u cycle sometimes make ur bike to swing more often imho.thus if u are a heavy weight person,then the joining parts could tear up if do like that.
beside that,
please check ur joining parts after ride.that is my habbit.fyi, i already cycle more than 5000km with my verge and until now im happy for it.my weight when i started to pedal the verge is 106kg and until now i manage to down my weight until 85kg.still want to drop somemore to use the lighten seatpost (litepro seatpost suggested 80kg and bekow).
for me,its more about precaution rather than blaming others.i know sometime we also unlucky to get the defected item,but that possibility are around 1/100 bike.please check all the joining parts before u buy the bike.
this incident could happen to all bike no matter what brand..as a tern user, also trinx and dahon owner all the bike i have are a good bike.i also had a dopplegangger that i bought scrap from japan used bicycle shop and rebuilt it.until now that doppelganger are in good condition!
the only matter is,how we maintain it make it different!!!
LEL> Even my cheapo Ugo,i also syg it like a brompton. After each ride will clean n wash. Scractches on it make me sakit hati.

i long long time wipe once that all for bike cleaning part.. just check all those hinge and lock and oil d bike.. no more than that.. so selalu kena marah sbb tak jaga bike...
