>>1301588Obviously you don't get a folding bike as a touring rig or to go fast.
You buy one if:
>your bike needs to be transportable>you combine multiple forms of transportation>bike theft is rampant, so you place your bike under your desk at workFor example I often commute by bike+train, bringing the bike on the train is free and even when the train is pretty full, the bike always fits.
You can also fold them, pack them in a suitcase and ride your own bike when far away from home.
A folding bike is the only bike that fits into my car (roadster), so when I drive somewhere and want to ride my bike there, it is my only choice.
