Advice on Folding Bicycle I am planning to buy a folding bicycle (brand doesn't matter). Intent is commuting to work inside the city (5-6 kms one side run). Reason for folding bicycle is space constraint in my apartment. I never rode a folding bicycle before I am curious to know how different it is from normal bikes riding wise and any additional maintenance is involved and durability compared to normal bikes 

Please advise.
A good folding bike should ride just as well and last just long as a traditional bike. BikeFriday has a reputation for bikes that feel "normal."

As far as maintenance goes there is very little difference. From my experience the only thing that needs more frequent maintenance are the cable housings. This is because cables usually have to make more complex cable bends on a compact folding frame. This causes the housing wear out a bit faster. From my experience about 33% faster than my traditional bikes.
