I began building unicycles in 1995 after Dustin Kelm came to me with a simple request to build an improved version of his Miyata freestyle unicycle. A poor copy of this frame was copied by unicycle.com and made over seas sold as the 20″ Nimbus free style unicycle. I was at the first and center of developing the first and final versions of touring unicycles working with Andy Cotter. With the final designs incorporating brakes on the frames to assist in down hill speed control, and the first touring extension for long distance riding. I build high quality precision unicycles and giraffes, including my proprietary pull apart travel giraffes. My custom Giraffes are a fraction of the weight of import giraffe unicycles, and stronger due to the aircraft grade cro-moly steel I use.
Custom unicycles are available just contact me with your needs and I will get you a quote. When ordering Giraffes it is critical for me to know what you are riding. A big misconception is the common 6 footer which is in fact by Giraffe standards is actually a 5.5 footer.
Base size calculations are as follows and how to determine the frame size is to measure from the center of the bottom bracket (crank set) to the center of the wheel axle. Sizes areas follows:
10 footer 84″
9 footer 72″
8 footer 60″
6 footer 48″
5.5 footer 42″
4 footer 36″
Please note I have found 5.5 footers have fallen in to a range of 39″ to 43″ I generally build custom Giraffes based o what you are currently riding and will need to get the frame measurement to replicate it. But if you are looing for a Stock custom frame the above numbers is what I go by when I build.
