Here BEN SOJA's comments on our URC 26-INCH after his Tour in South Africa (19.3. - 28.3.16)
" ....... The URC 26×4” unicycle I got from my sponsor Mad4One held up very well to all challenges on the way. During the adventure, I didn’t get a single flat tire and it survived all big drops and rugged terrain very well. For a steel frame and huge tire, the weight (under 7 kg) is very impressive – no problem to finish rides of 50 km or to carry it up a mountain on your back. I can highly recommend it as a great all-around unicycle....."
25.4mm in steel.  It is cheap and  just a little more heavy  compared to the ALU version. Steel is however more resistant.
Also the frame is in CrMo. it is a little more heavier than the ALU version, however more robust. The URC frame is the only one in CrMo with the Disc Brake mounting tabs. The URC Mountain Unicycle is available in 3 sizes: S, M, L. Here we mount the size M and you can mount wheels up to 28"x2.50. The great versatility of this frame allows you to purchase 1 Mountain Unicycle with perhaps 2 different wheels, each one for a specific purpose.


- assembled in Italy with high quality components.
- four cross spoke pattern that  gives high stability to the wheel.
- Spokes and nipples in carbon steel which ensure a high mechanical strength and durability.​
- Important Plus is given by the Mad4One ISIS disc hub.


The range of Shimano disc brakes we offer is extremely wide.

Excellent quality, in plastic with large sole, very robust however without metallic Pins.



It has been designed for beginners through experts. Ideal for Mountain Unicycle-Road, as well as Hockey and Basket. Contrary to the traditionally ones, this saddle comes with a gentle curve to reduce front pressure. The integrated handle provides high comfort (no hole, more security and more space for the fingers).
