Maribor, look no further. The Mobilnost centre in the heart of the towns offers pretty much everything any prospective cyclist could possibly be after, everything from gear to parts (recycled also available) to rentals and all found in between. It also runs a community self repair program known as Bike Kitchen, and can help with organising trips or trekking in the surroundings of the city. If this isn’t enough, it also offers a place to park your bike when in town.
