A wall-hung bike needs its own length along the wall, its own height plus the lift onto the hook, and a depth off the wall set by the handlebars or pedals, whichever is wider. Measure your bike for all four. A rotating mount swings the bike flat, so its depth becomes bar width rather than bike length.
Measure the bike, not a chart
Bikes are not one size. A road bike, a mountain bike with wide bars, a step-through town bike and a child’s bike need different amounts of wall, and the differences are big enough that a clearance figure for a generic bike is wrong for most of them. The good news is that a bike is easy to measure and only four measurements matter. Take them with the bike standing on its wheels, and take the width ones twice, because the widest point of a bike is either the bars or the pedals and it depends on the bike.
- 1LengthFrom the front edge of the front tyre to the back edge of the rear tyre, with the bars straight. This is the wall the bike takes side-on, and the depth it stands out when swung perpendicular on a rotating mount.
- 2HeightFrom the floor to the top of the bars or the top of the saddle, whichever is higher. This is the vertical wall the bike occupies once it is hanging, since it hangs in the same orientation it stands.
- 3Width at the barsBar end to bar end, including the grips and anything fitted to them. On a flat-bar bike this is usually the widest point of the whole bike.
- 4Width at the pedalsOutside face of one pedal to the outside face of the other, with the cranks level. On a road bike with narrow bars this can be the wider figure. The larger of this and the bar width is the depth the bike stands off a wall when flat against it.
- 5The top tubeWhether it is level, how long it is, and what it is made of. A rotating mount carries the bike by the top tube, so a steeply sloping tube, a very short one, or a carbon frame changes whether that mount is the right one at all.
What each measurement decides
Each of the four sets one dimension of the space the bike needs, and together they describe a box on the wall that nothing else can occupy. The box is bigger than the bike in two directions: upward, because you have to lift the bike above the hook to get it on and off, and outward, because whatever mount holds it stands the bike off the wall by the depth of the mount before the bike’s own width is added.
| Measurement | What it sets | Add to it |
|---|---|---|
| Length | Wall taken side-on; depth when swung out | Nothing side-on; the mount arm when swung out |
| Height | Vertical wall once hung | The lift above the hook to get it on |
| Wider of bars or pedals | Depth off the wall when flat | The stand-off of the mount itself |
| Top tube | Whether a frame mount suits it | A check on slope, length and material |
How a rotating mount changes the depth
A fixed hook holds the bike in one position. A rotating wall mount carries the bike by its top tube on an arm that turns through a full circle, so the bike can hang perpendicular to the wall for access and be swung flat against it when the space is needed. That changes which of your measurements is the depth. Perpendicular, the bike stands out from the wall by its full length plus the arm. Flat, it stands out by the wider of its bar width and pedal width, plus the arm, and the length now runs along the wall instead of into the room.
That is the whole argument for a rotating mount in a tight garage. The bike can be swung out to reach, and turned flat while the car is in, and the depth it takes in the way of a car door drops from bike length to bar width. It does not make the bike smaller; it lets you choose which dimension points into the room, and it lets you choose differently at different times of day.
The check before buying one is the frame. The mount hangs the bike by the top tube, so the tube has to be straight enough and long enough to sit in the cradle, and the frame has to be happy being carried there. Carbon frames and steeply sloped top tubes are the ones to think about, and some full-suspension frames have nothing straight to hang from at all. Look at your bike before you look at the mount.
Height off the floor
The mount goes on the wall at the height that puts the hung bike where you want it, and the sum runs from the wheels upward. The bottom of the lower wheel wants to clear the floor by enough to sweep under and to keep the tyre out of any damp at the base of the wall. From there, the bike’s own height puts the top tube where the mount has to be, and the mount has to be where you can lift the bike onto it, which is a measurement of you: lift the bike by the top tube and see how high you can raise it.
Anything walking underneath the bike also matters. A bike hung high enough to clear a head can be walked under; one hung at head height cannot, and a pedal at eye level in the dark is a thing you only do once. If the bike is above the passenger side of the car, the height also has to clear the open car door and the mirror. If it is on the back wall, it has to leave the walkway below it clear.
Two bikes, and a bike in a tight single garage
Two bikes side by side on the same wall take two lengths of wall and interfere at the bars, because the bars stick out furthest and they meet. Stagger the heights so one bike hangs higher than the other and the bars of one pass above the bars of the next, and the two bikes can overlap along the wall by nearly the width of a bar. That saves a lot of wall, and it is the only real trick in bike storage.
In a single garage with the car in, it is often the case that a bike cannot hang on a side wall at all at door height, because the car door swings through the space. It can hang above the door line if the wall is high enough to lift it there, it can hang on the back wall if you can reach the back wall with the car in, or it can go on a rotating mount and turn flat while the car is parked. Measure the bike, measure the gap, and let the smaller one decide.
Common questions
- How much wall space does a bike need?
- Its own length along the wall if it hangs side-on, its own height plus the lift above the hook, and a depth off the wall set by the wider of the handlebars and the pedals plus the mount itself. Measure your bike for each, because bar widths and lengths vary enough between bikes that a generic figure is wrong for most of them.
- How far does a bike stick out from the wall on a wall mount?
- On a mount that holds the bike flat, it stands out by the wider of its bar width and pedal width plus the depth of the mount. On a mount that holds it perpendicular, it stands out by its full length plus the arm. A rotating mount lets you choose, and swinging it flat is what saves a car door.
- How high should a bike wall mount be?
- High enough that the lower wheel clears the floor with room to sweep under, and no higher than you can comfortably lift the bike by the frame to get it onto the mount. If people walk under the bike, it needs to clear a head. If it is above the car, it needs to clear the open car door and the mirror.
- Can I hang two bikes next to each other?
- Yes, and stagger the heights so the handlebars of one bike pass above the bars of the other. The bars are the widest part and they are what collide. Staggered, two bikes can overlap along the wall by nearly a bar width, which is the difference between two bikes fitting on a wall and one.
