I just had a Steppenwulf bike ordered through these guys, and my experience was great! They even stayed open late for me after I called and told them I was rushing there. They have a great selection of Steppenwulf bikes, as well as other cruisers, road bikes, and touring bikes. For Steppenwulf, you're going to spend some money, but it's a German-made brand, so for me it's worth it.
They even threw in a bag for free, which was pretty great :-)
You can also find a wide selection of add-ons: helmets, bells, baskets, bags, and locks (which are oh-so-important in Munich).
They also have the coolest vending machine I've ever seen outside. They sell all types of Continental tubes there, so even if you get a flat on a Sunday, you're covered!
The guys there are super-knowledgeable, and were great with English (though they are a bit shy about it).
If you're looking for a bike in Munich, I'd suggest looking at these guys. read more
