I'm about to embark in a garden storage project. Basically it will be large cupboards along a wall around 5m long I have not decided on depth yet as looking at options. The question is what position to store or hand bikes. There are 4 of us 2 kids 2 adults I have 2 bikes but would like room to expand and obviously the kids will grow. Option1. Put bikes flat (sideways to wall). Requirements height 2m ( one bike above another) length 4 meters (2 bikes long) depth 0.5m max. This seems t take a lot of wall space. Option 2. Bikes stores with wheels on wall using hangers on wall. Requirements. Height 2m (bike wheel to wheel), length for 4 bikes 2m( may expand for growing numbers) Depth 1 meter (wheel to seat height). Are there any other options I have missed or advice on the build.
