Assembling your unicycle
How to assemble
his unicycle?
You've just received your box and you're wondering how to assemble your unicycle? Follow our step-by-step visual instructions to install the wheel, seat, and pedals without making any mechanical mistakes.
- Assembly in 10 minutes
- 10 & 15 mm wrench
- Zero hassle
Good tools make good jugglers
No need to empty the garage toolbox. Assembling your unicycle requires only minimal equipment: a 10mm open-end wrench and a 15mm open-end wrench . Unpack all the parts from your box to check that you have the frame, wheel, saddle, pedals, and seat post.
Determine the front and the back
This is THE tricky question during assembly. Yet, the correct orientation is very easy to find: the slot in the seat clamp (where the fork metal is cut to tighten the tube) ALWAYS faces backward . Another foolproof clue: the unicycle seat is generally wider at the rear than at the front.
Tightening the wheel bearings
It's time to attach the wheel to the fork by securing the bearings (the small curved pieces that hold the axle). The secret to a smooth unicycle wheel is a firm but moderate tightening. There's no need to overtighten: if you overtighten the nuts, you'll crush the ball bearings and the wheel will spin very poorly. Always be gentle!
⚠️ Pedal direction & adjustment
This is the critical moment of assembly: installing the pedals! They have a reverse thread depending on the side.
- ➡️ The pedal marked R (Right) screws on the right.
- ⬅️ The pedal marked L (Left) screws on the left.
The Golden Rule: Initially, the pedals should screw on easily by hand, with zero effort. If they require resistance from the very first turn, STOP! Do not use a 15mm wrench; you'll strip the threads on the crank arm (and you'll have to buy a new one).
Adjusting the saddle height: Slide the seatpost into the fork. If the saddle is too high even when lowered to its lowest position (very common with children), don't panic! Simply cut off the excess metal post with a hacksaw to adjust it to the rider's height.
How to get started?
Your unicycle is assembled, the seat is at the right height, the tire is inflated... It's time to hop on! Let's be honest: the first hour might drive you crazy. But once you get the hang of balance, there's no stopping. Here are our 3 golden rules for surviving your first session:
The door frame
For your very first attempts, find a door frame or railing to hold onto on both sides. Position your right pedal at the "4 o'clock" position, sit with your back straight , and look straight ahead. Never look at your wheel, or you'll fall forward!
Knowing how to fall (letting go)
If you lose your balance forward: let go of the unicycle! Do not hold onto the seat. Let the unicycle fall to the ground (the seats on our Luxus and Only One models are equipped with robust plastic protectors specifically for this purpose) and land gently on both feet.
Prepare your comeback
Practice smiling. As soon as you go for a ride outdoors on a bike path or in a park, at least three people a day will tell you the famous joke: "Hey, you've lost a wheel!" It's the price you pay for being so cool.
Which unicycle should I choose to start with?
If you stumbled upon this assembly tutorial before even ordering your wheel, here's a reminder of the most reputable unicycle sizes and ranges to get you started. (The Only One range for smaller budgets, and the Qu-Ax Luxus range, the go-to choice for circus schools).
12 Inches
Minimum inseam: 48 cm.
Extremely easy to handle for toddlers. Perfect for playful learning.
16 Inches
Minimum inseam: 54 cm.
An excellent compromise for making rapid progress in the garden or at circus school.
18 Inches
Minimum inseam: 54 cm.
The perfect intermediate size between 16" and 20". Ensures a smooth transition.
20 Inches (The Standard)
Minimum inseam: 61 cm.
This is THE absolute standard size. Whether you're 15 or 45 and just starting out, a 20-inch is what you need!

Thank you for your answers ;-) and very good site, looking forward to the video which explains how to use the toolbox
If you are near Avignon there is a circus day on April 12th...
