The details that matter
Everything you need to know
Fit, geometry, components and the details behind the ride.
Designed around the rider
The details you might not notice. Your child will feel them.
The engineering choices that make YOMO 18 feel natural, controlled and fun to ride.
6.6 kg
Lightweight build
Easier for children to start, steer, lift and stop.
At 6.6 kg, YOMO 18 keeps the ride manageable so your child can focus on confidence, not fighting the bike.
Forward fit
Child-specific geometry
Balanced handling for smaller bodies.
YOMO geometry is built around a child’s proportions, helping riders sit naturally, steer predictably and feel in control.
Small-hand fit
Scaled for children
Controls and contact points matched to young riders.
From grips and levers to cockpit sizing, the details are chosen so the bike feels natural rather than oversized.
Efficient pedalling
Narrow Q-factor
A more natural pedalling position for smaller hips.
The child-specific crank setup supports smoother pedalling and avoids the wide, awkward stance common on many children’s bikes.
Easy to ride
Single-speed simplicity
No gears to think about while confidence grows.
A clean single-speed drivetrain keeps the 18 light and low-maintenance, ideal for the stage between first pedals and first gears.
130° headset
Controlled steering
Keeps steering predictable while learning.
The safety headset limits over-rotation, reducing sudden handlebar twists during early riding.
Clean and protected
Compact chainguard
Keeps the drivetrain safer without bulky plastic.
The slick compact chainguard helps protect little legs and clothing while keeping the bike looking premium.
Smoother rolling
Sealed bearing hubs
Smooth rolling, low maintenance and no sharp axle edges.
Sealed bearing hubs help the wheels roll smoothly and keep maintenance low, with child-friendly hardware details.

Still deciding?
Ask us anything about the YOMO 18 and we’ll reply by email.
Ask us about YOMO 1801What size child does this model suit?
YOMO 18 is designed for riders aged approximately 5–7 years, with an inside leg of 49–60 cm and rider height of 110–125 cm. Age starts the search; inside leg confirms the fit.
02How much assembly is needed?
YOMO 18 arrives 99% assembled. Align the handlebar, fit the pedals, complete every safety check and follow the included setup guide before the first ride.
03How do I set the saddle height?
For a newer rider, start low enough to place the balls of both feet securely on the ground while seated. As confidence grows, raise the saddle so the leg keeps a slight bend at the bottom of the pedal stroke, without exceeding the seatpost limit mark.
04How do I adjust the brake lever position?
Loosen the lever clamp bolt slightly, rotate the lever to a comfortable angle for the rider hand, retighten it securely and confirm both brakes engage fully before riding.
05What if a brake rubs?
Check that the wheel is seated correctly and the brake pads sit evenly beside the rim. Use the brake-arm spring-tension screws only as shown in the setup guide, then confirm the wheel spins freely and both brakes stop the bike securely.
06How often should I service it?
Check brakes, tyre pressure, chain condition, wheel security and bolt tightness regularly. Arrange a yearly safety check by a qualified bike mechanic for regular riders.
07Where is the serial number?
The serial number is stamped underneath the frame around the bottom-bracket area. Take a clear photo after purchase for registration, warranty and support.
08What is the maximum rider weight?
The maximum total load for this model is 55 kg, including the rider and anything they carry. Staying within it keeps the frame, wheels and components working as designed.
09What tyre pressure should I use?
Use the permitted pressure range printed on the tyre sidewall. For a lighter rider, start in the lower part of that range and adjust for grip and comfort. Never exceed the maximum shown on the tyre.
10What happens when my child outgrows it?
YOMO BikeTrade lets you trade in an eligible YOMO towards the next size. The calculator gives an estimate; final credit is confirmed after inspection and depends on age, condition and the current programme terms.
11What is the warranty?
YOMO bikes include a 3-year frame and fork warranty as standard. Eligible bikes registered within 30 days receive lifetime frame and fork cover for the original purchaser. Other components are covered for 1 year against manufacturing faults. Normal wear, crashes, misuse, poor maintenance, incorrect assembly, modifications, improper repairs and cosmetic marks from use are not covered.
12Can I return it if it is not right?
Unused bikes can be returned within 30 days in their original condition, packaging and with all accessories included. Contact YOMO before returning the bike; collection costs may apply to unwanted returns.
