Repairing (and renting) bikes in Copenhagen

Having a bike in Copenhagen is like having legs. Keeping them in shape is as important.
You'll have to fix a flat tire several times, especially if you ride on wet asphalt.
To change a tire, fix the brakes and do some other things is not so complicated and you should learn to do it yourself. If you are too lazy though you better find the right mechanic, unless you want to spend more for repair than for a new bike at Kvickly.
Finally, one more tip to preserve your bike. Bicycles get stolen in Copenhagen as well, not as much as in other places, but they do. The worst place where you can leave your bike is near a train or metro station at night. Either professional thieves or drunken people on their way home are very likely to take advantage of your bicycle.
