Instructables
After seeing an instructable for a bracket to hold a unicycle to a motorbike I thought that I would post pics of my solution to the same problem. I have included plenty of views so you can figure it out for yourself. Sadly I have no photos of it being made.

I came up with this bracket design after several iterations that held the unicycle in various places on the frame and wheel. This final design uses the end of the crank where the pedal screws in as the main holding section. A small elastic strap stops the crank from swinging forwards.

The pictures do not show it attached to a bike as I wrote my motorcycle off whilst simultaneously learning that a motorcycle crash is far more painful that a unicycle crash. When mounted to a motorcycle it bolts onto the mounting holes in the motorbike frame. The unicycle leans downwards and forwards and the seatpost is strapped to the pillion footpeg. The result is a bracket that is discreet and easy to attach the unicycle to. It will hold a variety of sized unicycles. I have used it from 20" up to 29" wheels.

Got any questions? Feel free to ask.

Cool instructable - how does the uni hold up at speed - only ask as I want to fit an external bracket to my Suzuki Jimny but do not want have issues with it coming loose.

Another thought - strap it to the bull bar if you have one - that could look cool.
Now that would have been a cool idea I had not thought of - guess what - yup!, no bull bar - bugger it.

Good thought for folks who do though.

Cheers DZ

On a scooter the unicycle was fine. It didn't bounce around much as there is a good bit of suspension over the scooter's back wheel. I think that the biggest issue of a car mounted bracket would be the unicycle wanting to jump out when ever you hit a bump. Have a look at John Foss' method of mounting a uni to a car http://www.unicycling.com/garage/bigwheel.htm. Probably to highly specific for your intended purpose.
That said, I would be more inclined to keep the uni safe by keeping it inside the car rather than putting it on the outside where it will add drag, may get rained on, stone chipped and or stolen.
Cheers - will check out that link.

The reason for putting the uni outside is that the wife and I would be taking two inflatable kayaks and a folding bike, plus cloths, all in my poor little Suzuki Jimny - a soft top too so no roof rack for me.
