Ever wish you had more space for your growing collection of bikes? Sticking out just 16.9 inches from the wall, the (translated) Motorcycle Garage can hold your gear and tools, then can expand open to cover your entire bike. Designed to cover a motorcycle, it should have no problem covering a few mountain bikes.
The website is written in Deutsch, and does not mention a price, but the graphics and pictures show a lot. Made of aluminum, it can be locked to keep the elements and thieves away from your ride. If you don’t have a garage or access to covered storage, it can be a great option for your stuff and has options for mounting against a building or being free standing.
