International Unicycling Federation
Over the English channel and into Europe Race or Track Unicycling is a big deal, the IUF (International Unicycling Federation) call the discipline "Race" and describe it as:
"Unicyclists race common distances like 100m, 400m, 800m on an athletic track. There are a wide variety of races along with standard riding, such as wheel-walking and riding one footed."
Only standard unicycles may be used. Riders may use different unicycles for different racing events, as long as all comply with the rules for events in which they are entered. For events divided by wheel size, there is a maximum allowable tire diameter and minimum crank arm length for each category:
| Unicycle Class | Max Diameter | Min Crank Length | Transmission |
| 16 Class | 418mm | 89mm | Standard |
| 20 Class | 518mm | 100mm | Standard |
| 24 Class | 618mm | 125mm | Standard |
| 29 Class | 778mm | No Limit | Standard |
| Unlimited | No Limit | No Limit | Unlimited |

We have just started selling the 24" Nimbus 'E-Sport' Race Unicycle, which is a Unicycle designed to compete in the IUF 24 Class. The E-Sport Race comes with a 559mm rim and a thin tyre so it is designed and optimized to ride on a track. This unicycle conforms to the IUF’s track racing rules and unicycle specifications.

The E-Sport Race
The Nimbus E-Sport race unicycle is at the top of its game with the best unicycle parts and newest technologies. It comes with the latest generation Nimbus one-piece aluminium (90mm wide) hub for optimum race performance and durability. The super stiff Nimbus VCX cranks give the most efficient transfer of power directly to your wheel, meaning all your power goes solely into propelling you forward to victory.
The E-Sport's Frame
The Nimbus aluminium E-Sport frame is narrow enough at the top to minimise catching your knees but still has enough crown to enable a secure foot placement for one-foot riding. With the E-sport frame being 300mm long (from crown to top of seatpost) this puts the seatpost clamp nicely out of the way minimising any discomfort.
