Below the 3 basic concepts on which we designed and tried to optimize the product:
  1. Contrary to the bicycle, the unicycle has only one point of contact with the ground, so when we push on the pedals, the force we apply on them makes the wheel spin around the hub, but at the same time it also pushes sideways towards the point where the unicycle contacts the ground. This produces the classic side-to-side oscillations of the unicycle, which is the number one enemy of high speed. The oscillation generated by our pedaling can be reduced by reducing the distance of the pedals from the center. This is the reason why if we want to have a high performing race unicycle the distance between the pedals must be as much as possible narrow.

    We have worked on the weight distribution, reduced as much as possible the distance between pedals thanks to our 85mm hub, we have optimized both cranks and interface connecting cranks- hub, we have achieved a high level of stiffness of both frame and wheel.

  2. We have experienced, that rigidity in RACE is more important than lightness. The more rigid your unicycle is, the lower the vibration will be at high speed.
  3. The wheel with the "right" weight (we mean not too low) will help you in keeping constant the frequency of your pedaling at high speed.


All MAD-RACEs comply with the 24" IUF Class

A few words about the 24 Unicycle Class according to the IUF Rulebook.

The IUF Rulebook, go to chapter 2B.2 of the “2019 Competitor Rules” , does not specify the size of the tire, it refers only to "the tire diameter range"  allowed, that is,  the diameter of the entire wheel including the tire.

As regards the 24 Class it says that the diameter range must be "more than 518mm - 618mm"  and the cranks must be at least 125mm long.

  • The MAD-RACE 24” has a wheel-diameter, including the tire, of 606mm.
  • The MAD-RACE 26” has a wheel-diameter, including the tire, of 616mm.

Therefore all MAD-RACEs comply with the IUF 24" Class.
