Q: What is the correct number of bikes to own?

A: N+1

Q: How the hell do you store all these bikes?

I couldn’t find anything on the market that was compact, sturdy, adjustable, and protected my frame/fork and disks. I wanted something on the ground that the bikes could just roll into, especially for the heavy e-bike.

This rack stores any number of bikes ‘top to tail’ for maximum space utilisation, or spread out for ease of access. Bikes can be spaced however required. Any number of bikes can be added - only limitation is the length of tube.
They can even be added ‘back to back’ for twice the storage.

It works as a single bike stand too.

It only makes contact with the tyre, fits any size wheel (shorter / longer tubes can be used as required), and has been tested on tyres from 30mm to 2.4”. The two step design means the same parts work on MTB or road tyres.

Optional TPU feet to grip the garage floor.

Parts Required

You’ll need approx. 3m of 16mm tube per bike – I used curtain rod from Bunning for all the short pieces. It's cheap and plenty strong enough for the application. I used 1.2mm gal tube for the long pieces connecting all the stands for a bit more stiffness though this is probably overkill.

20x M6x16mm bolts and nuts per bike – optionally you can use dome nuts for most of the exposed threads but you’ll need to ensure you don’t go longer than 16mm bolts

2x M3x8mm approx button head bolts to fasten the TPU feet if using - plus 1 per side support

Instructions

I printed in eSun PETG with 3 walls (4 for my E-Bike just in case - though this was overkill).
It should work fine in PLA+ but I haven't tried.

Print all the parts in the ‘PETG’ file as oriented. Supports are only required for the main ‘middle’ piece under the edge of the braces that span between the tubes (exactly where the tyre makes contact). They need to be painted manually or you'll get supports everywhere.

Print 2x left and 2x right side supports total (included in the PETG file). Whether you are building for 1 bike or 5+ you only need them for the end pieces. They aren't really needed for 3+ bikes as they won't topple but I still used them for aesthetics and to make the end bikes wobble a tiny bit less.

Print 2x TPU feet for each bike plus 4 extras for the side supports if using TPU feet.

For each bike cut 2x 600mm lengths of tube and 2x 400mm lengths of tube. The 400mm lengths are the horizontals. The 600mm lengths are the verticals.
You might need slightly more than 600mm for 29” wheels (600mm tested with 26”/650/27.5”/700c)

For a 16” bike I used 270mm horizontals.
If you're making one stand, use the remaining 1m to make 2x 500mm pieces for the side braces.
Debur the tubes so they slide into the parts easily.

Bolt everything up as pictured or shown in the ‘assembled’ STEP file. If you're doing multiple bikes, don't tighten anything until all parts are in place.

I spaced my bikes 450mm centre to centre. You could probably go closer if you don't have oversized handlebars.

Tighten all but the top spacer(s).

Put your bike in the stand and adjust the height of the top spacer until it supports the wheel but does not push down on the wheel. The bike should roll out relatively easily, but the spacer should still keep the bike upright.
If the bike is difficult to remove, the spacer probably needs to be shuffled up a mm or so.
Slide on the top caps to cover any sharp edges.

Optionally use your slicer to add text to the sign and print a name plate for your bike - since the stand is adjusted to a specific wheel it's nice to know which bike goes where.

Edit 24/11/23 - I had the wrong ‘top caps’ in the PETG parts .3mf file. The updated file has a top cap piece that fits the tube better
While I was there I split the side feet out into a separate plate since if you're doing multiple bikes you only need one set of feet.
