I really don't understand why you'd buy a bike like this. Why spend more money to get an technically antiquated old fashioned design when a cheap modern rigid mountain bike would be perfect? If you were cycling in the wilds of bornea and needed a bike which could be repaired with only a large rock (and most likely was designed on one) then I could see why, but you're in a city - only metres away from civilisation, coffee and buildings with roofs.
Just because the Dutch use them doesn't mean you should. Have you ever been over there, it's hundreds of people wandering along at 10mph in an environment where you need a cheap bike as there's a good chance you'll forget which giant pile of bikes you left it in.
