Why Hybrid?

Because it's exactly what it sounds like – the Hybrid Roadrunner is a mix of the TOP of the range mountain unicycle and a very interesting, high quality, strong lightweight road unicycle. It is suitable for riding on various terrains and mounts high end components which make a massive difference in your happiness on the unicycle:

  • the VEE SpeedSter 27.5 and 29” tire, designed for high speed and minimal rolling resistance on hardpack and paved terrain,

  • MADTecno cranks, super strong or the Agile ones, strong as the MADTecno however lighter in weight,

  • A wide range of Shimano disc brakes, from the M4100 to the M820 Saint.

Mad4One's new Hybrid, driving it is a real pleasure




We build it for you as we did in 2018 for Mjriam Lips. Mjriam wanted a geared Mad4One 32” to train and break the 100 km world record. We did it. She delivered us the Schlumpf hub, as well as rim, spokes and tire. We handcrafted the wheel, mounted the Mad4One aluminum frame, size L, the MADTecno 2 holes 110-130mm cranks, the Mad4One XXL seatpost and the Mad4One HandleSaddle size L. Before delivery we tested the 32" here in Varese with Mirjam and then her training did start.



Mjriam took on the 100km track world record on September 19th, 2020 at the military airport in Emmen near Luzern, Switzerland. She completed the 20 laps of the track in 3 hours, 45 minutes and 53 seconds. She has not only beaten her previous world record, she is now also very close to the male world record! 

Here the link to the Mad4One frame, size L, we mount on the 32" wheel: FRAME L.



One of the Mad4One Spring 2021 novelties will be the Mad4One aluminum frame 36”.

Here we will offer the same service we do for the 32”.


However, if you wish, you can simply buy the frame and assemble the unicycle yourself.





We have decided to mount on our Mad4One and URC unicycles the Shimano's hydraulic disc brake systems because they are very modular in braking, precise and of quality.

We do not say that they are the absolute best choice, but experience tells us that they offer excellent modulation, ensure a reliable, consistent, stress-free braking performance and are well appreciated by a wide range of riders with different braking styles.
