THE MAD4ONE ROAD UNICYCLES

These adventure road unicycle combine the off-road capabilities of a mountain bike with the speed and efficiency of a road unicycle. Be ready for whatever comes your way with these quick, confident adventure touring unicycles.

Road unicycling is riding on usually sealed roads and (bicycle) paths, where the main goal is covering a (short or long) distance.  It could be a sightseeing ride, or riding in the street with friends for fun.  Road and Muni cannot be strictly separated: there is a gray area associated with riding on semi-paved or very easily rideable roads and paths. Road Racing are unicycle races on public roads, where those roads may or may not be closed to other traffic. Common distances for road racing are 10km and marathon (42.195km).

What's the difference between Mad4One and URC?

MAD4ONE'S NEW HYBRID, DRIVING IT IS A REAL PLEASURE.

Every Mad4One Road unicycle is designed to deliver best-in-class performance, from our quality road machines with steel frame to our    refined aluminum models. These are the stable, fully customizable road unicycles that will bring you over all-terrain surfaces and make you enjoy your extensive adventures. You'll feel the difference, from the first ride all the way to the podium.

1 Traditional saddle or Handle Saddle

An innovative option is for sure the Handle Saddle. Born in 2017 the Handle Saddle is the new generation saddle developed by Mad4One. Excellent in solidity, lightness and stiffness, the Handle Saddle ensures full control of your unicycle, thanks to the formidable handling and great reliability it offers on challenging trails and steep downhills. Combined with the Mad-Extension it offers the possibility to customize the position of your hands.

2 Unbreakable Seatpost

It’s important that you can rely on an unbreakable seatpost. The 40 cm long Mad4One XXL seatpost is a concrete example of great stiffness and durability. Made from AL-6061-T6 aluminum alloy, forged in one piece and reinforced in the part most subject to stress, the MAD-XXL is the right choice for heavy duty use. In the design of the Mad4One seatpost XXL and the 3B Double Clamp we've paid great attention to robustness, tightness and solidity. They are the right combination for a formidable hold between seatpost and frame.

3 Great tightness with the 3B Double Clamp

One of the parts that breaks most in the unicycle is the seatpost. One of the most common problems is the saddle that moves when you ride. These are the problems we think to have solved with our 3Bolts double clamp and the Mad4One XXL seatpost.Like the XXL seatpost, the one-piece CNC machined 3B double clamp is an innovative solution designed and produced by Mad4One. The 3B Double Clamp  provides a formidable grip that locks firmly seat tube and frame together.

7 Handbuilt wheel

The wheels mounted on our unicycles are all handbuilt by us in our laboratory and arranged in a 4X spoke pattern. This means that every spoke intersects four others between the hub and the rim. Crossing the spokes over helps them handle the pedalling braking torque being transmitted from the hub to the rim. The 4X lacing pattern requires an accurate and more expensive assembly process, that, combined with the high quality components used, ensures a much better durability and stability of the wheel.

4 A wide range of Shimano disc brake systems

There's a massive variety of performance across the spectrum we offer, from the first option we propose, good in what it does and comparable in quality to the disc brake systems you usually find on the best known mountain unicycles available on the market, to the more powerful ones, up to the 4-piston braking systems, which offers excellent modularity and superior stopping power in all conditions, instilling great downhill confidence and control.

5 The frame, stiff, stable and reliable, born from competition

The round Mad4One frames are made from aluminum alloy AL7005-T6, that compared to the more common AL6061-T6 has a greater load resistance (+ 12%) and a higher fatigue resistance (+ 56%). The URC frames are made from CrMo-4130 chromium-molybdenum steel, an alloy that guarantees greater load resistance, lower specific weight and better tensile strength compared to unalloyed steel. In the design of our frames we paid also great attention to the shape and the diameter-thickness ratio of the tubes. Furthermore, we paid great attention to the shape and the diameter-thickness ratio of the tubes.

6 Mad4One ISIS cranks, the ony ones made from ERGAL AL7075-T6

There is also a wide choice of cranks. We go from the standards ISIS UnicycleStuff, 1 hole, up to the high-end MAD-Tecno or AGILE. Both Tecno and AGILE are 100% compatible with any ISIS-hub. They come out of the same aluminum mold and are made from ERGAL AL7075, the aluminum alloy that offers the best strength and stiffness. But where does the difference lie?  In the finishing phase the Tecno are beveled while the AGILE are further milled with different CNC machining that optimize the weight without compromising the strength (they are 30% lighter than the Tecno). Furthermore we tried to reduce as much as possible the Q-Factor and we succeeded. In fact, the AGILE are narrower than the ISIS-standards. Their Q-Factor has been reduced by 3mm per side, for a total of 6mm. A narrow Q-Factor improves riding efficiency (better power generation and more aerodynamic), that is very important at high speeds, such as speed on the track.

We are often identified for the rich variety of colors and possible combinations we offer, but our main identity is that of design engineers who pay great attention to functionality and stability. Why the colors? Because the unicycle is also fun and passion, if it’s monotonous and without personality what pleasure is it?

The frame: which size is the right one for me?

If we add the height of the frame to the thickness of the saddle and the length of the cranks, we have our  "minimum leg length". Here we are talking about the B-value of our unicycle.

The wheel: which size for your frame?

After having defined the right frame size for you, be it a URC or a Mad4One mountain unicycle, you need to know which wheel sizes can be mounted on that frame. The aluminum frame is available in 3 sizes and the URC in 4 different sizes.

Some important measures to avoid mistakes

What is the right saddle height? How do I measure my leg length? How do I calculate how long my seat tube should be? These are some of the questions we ask ourselves when we start configuring our new unicycle.

First I read the instructions to assemble my unicycle

I have just received my new unicycle and first I carefully read the assembly instructions I found in the box. This information is useful not only for the assembly phase, but also for the correct use and maintenance of my unicycle over time.

The brake on the unicycle is used differently from how it is used on the bicycle

The main purpose of the bicycle brake is to reduce the speed of the bicycle or to prevent it from moving. On the unicycle, the brake is used to regulate speed and to keep control when riding downhill even at high speed. It is therefore easy to get used to "keep on pulling the brake lever" even just with light pressure, on long down-hills. This light and prolonged use of the brake is a mistake that can cost you.

Let's extend our Handle Saddle ... here is the MAD-Extension

A saddle that can be adjusted both in inclination and extension allows weight to be distributed, improving comfort, especially over long distances. There are various solutions on the market. The Mad-Extension is the right one if you already have or wish to have the Mad4One Handle Saddle. There are 2 mounting systems available: the standard Mad4One and the URSLI.

The Handle Saddle, the most light and durable unicycle saddle

The Handle Saddle is a new concept of saddle that Mad4One has brought on the market, with a weight nearly half of the one of a traditional saddle, however stiff and strong as a traditional saddle with a carbon base, compared to which it is still lighter. In the development of the Handle Saddle priority has been given to the "easy catch", the "easy handling" and the "freedom of movement". This is the Handle Saddle of Mad4one available in different sizes and finishes.

How we developed the Mad4One's aluminum and steel frames

The unicycle is the result of the choices made by the designer. There are many ways to design a mechanical detail, but only a few of them are the right ones. That's why some choices make the difference. Weight: it’s important, but if it's light and weak it's useless. The material: the Mad4One frames are built with more performing aluminum alloys than the common AL6061-T6. The URC frames are made from CrMo-4130 chromium-molybdenum steel, one of the best alloyed steel available on the market today. CrMo-4130 guarantees greater load resistance, lower specific weight and better tensile strength compared to the simplest steels alloyed with carbon. Compatibility of the components: it means freedom for you to upgrade and improve.

The Mad4One World Championship medal board

Mad4One is the TOP of the range for mountain unicycling. This is confirmed by the great results achieved by many Top Muni Riders around the world, who have won many World Champions on their Mad4One Munis. The "Mad4one medal table", which we are particularly proud of, is the list of the best results achieved by riders who have attended the last World Champions riding a Mad4One muni.

Disk brake with 2- or 4-pistons brake caliper?

The Shimano brake systems Deore M4100 and M6100 are now available in four-piston versions, too. It features the same tech as the two-piston version and looks nearly identical to the rest of Shimano's four-piston brakes, but it’s not the same. "Mo´power mo' modulation" are the main advantages you get from this new version.

And what about the 32"?

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 Handle Saddle size L. Before delivery we tested the 32" here in Varese with Mirjam and then her training did start.

2020 - Mirjam Lips sets new 100km Unicycle World Record

The multiple World Champion Mirjam Lips took on the 100km track record on Saturday September 19th, 2020 at the military airport in Emmen near Luzern, Switzerland. The starting gun was fired at 9:00 a.m., and the record was broken shortly before 1:00 p.m. Mirjam (27 years old) completed the 20 laps of the track in 3 hours, 45 minutes and 53 seconds, beating the previous WR (also this one was established by Mirjam) at 4 hours, 23 minutes and 17 seconds (she was riding a 29" wheel with geared hub and 125mm cranks).

 This time Mirjam has set the WR with a Mad4One 32-inch unicycle.

Marco Vitale of MAD4ONE says:

It was an honor for us to build this unicycle for Mirjam.She delivered us the Schlumpf hub as well as rim, spokes and tire. We handcrafted the wheel in our lab, mounted the Mad4One aluminum frame in size L, the MADTecno 2 holes 110-130mm cranks, the Mad4One XXL seatpost and the Mad4One Handle Saddle size L. Before delivery we tested the 32" here in Varese with Mirjam and then we delivered it to her house.

Front pommel for Handle Saddle Front pommel for Handle Saddle

Price €29.41


The pommel is attached to the Handle Saddle handle with laces. It is a small accessory to prevent you from "sliding" forward on the saddle while riding. This often happens when we pedal without keeping our weight properly on the saddle. We will acquire the right posture with time and practice, but until then, if it helps, we can mount the saddle pommel on our Handle Saddle.
