Have you in mind to mount your HandleSaddle laterally? In this case a brake system with an openable brake clamp is the right choice.​
The alloy used, AL7005, is of high quality and is in 17 different colors anodized. You have simply to choose the one you prefer. The Mad4One frame has double Disc Brake mounting tabs and double cable holder. The most critical point of the unicycle frames (both shapes, square and round) is the junction between seat tube and crown. This Mad frame has a double butted reinforcement seat-tube that makes it one of the strongest.


Handcrafted by us in our laboratory in Italy.
The four-cross lacing spoke system gives high stability to the wheel.
2 options as regards the rim: reinforced or with lightening holes, anodized in 14 different colors.
Spokes and nipples in carbon steel which ensure a high mechanical strength and durability.
Important Plus is given by the Mad4One ISIS Disc Hub made of tempered steel.
The system Hub&Cranks is super strong!


Extremely high robustness. Q-Factor 0, as your pedalling is more efficient. The distance between the holes has been optimized so that your riding becomes more effective.

the large volume of air makes our riding much more smooth, even on rough terrains. Combined with a large (but not too much) Rim (47 mm) the tire form becomes more rounded and easy to use, even when cornering. For the highest stiffness and stability of your wheel, you can choose the reinforced 46mm double wall rim. You will have high comfort and great fun! If you like speed, nothing prevents you from mounting a more traditional tire (do not hesitate to ask, we will make the change).


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


Mad4One, version Comfort, is ideal for Mountain Unicycle-Road, as well as Hockey and Basket. It has been designed for beginners through experts. Contrary to the traditional ones, this saddle comes with a gentle curve to reduce front pressure. Very good price/performance ratio. The integrated handle provides high comfort (no hole, more security and more space for the fingers).



Leg length: 80 cm min. (with cranks 148mm and saddle Mad4One Comfort)
