Cube Kids Bikes Guide: Top Models & Sizing

The right Cube kids’ bike depends on where your child wants to ride and how confidently they can handle it, not just their age. The range includes wheel sizes from 12 to 26 inches, with options suited to first rides, everyday cycling and more adventurous trails. Fit matters just as much: your child should be able to reach the controls comfortably and stand over the frame with room to spare.

Choosing between a mountain, trail, gravel or dirt-jump bike can feel daunting when each style is designed for a different kind of riding. This guide explains how to match your child’s riding style to a suitable Cube kids’ bike, then assess brakes and controls, saddle height and standover clearance. Use these practical checks to narrow the options and find a bike your child can manage now, while building confidence on the rides they enjoy.

Child-friendly brakes, saddles and handlebars

Brake reach matters as much as braking power on a child’s first rides. The CUBE Numove 200 Disc has child-specific brake levers and 140 mm disc rotors. These levers are designed with smaller hands in mind. The Numove 240 Disc also uses 140 mm rotors in its Tektro hydraulic disc brake system. Those model details offer useful comparisons when considering how a child will control a bike.

During a stationary fit check, ask your child to hold the grips and operate each brake lever. Their fingers should reach the levers without stretching or shifting their palms off the handlebars. Ask them to squeeze and release each lever several times. Check that they can do this smoothly while keeping a secure grip. If a lever feels awkward to use, controlled stopping may be harder to practise.

Saddle position affects your child’s balance and pedalling. Set it so they can sit squarely, hold the handlebars comfortably and pedal without rocking their hips. For a first check, have them sit on the bike with one foot grounded, then pedal slowly in a clear space. If their knees remain sharply bent at the bottom of the pedal stroke, the saddle may be too low. Adjust it in small increments and repeat the check.

Handlebar width and position affect steering comfort. Ask your child to hold the grips with relaxed shoulders and slightly bent elbows. Their wrists should sit naturally, not bend sharply towards the controls. Check that both brake levers remain within easy reach in this position. If your child has to lean forward or lock their elbows, reassess the fit before a longer ride.

• Check reach to both brake levers while your child holds the grips.
• Test smooth squeezing and releasing before practising stops at low speed.
• Adjust saddle height in small steps and reassess pedalling comfort.
• Look for relaxed shoulders, comfortable wrists and secure control of the handlebars.

These checks help distinguish a bike that merely looks the right size from one your child can control. Repeat them after adjusting the saddle, as a change in height can affect reach to the handlebars. A Cube model’s brakes are only one part of the fit: hand position, balance and confidence matter too.

Kids’ mountain, trail, gravel and dirt-jump bikes

Start with the kind of riding your child enjoys, then compare suitable CUBE models. For paths, parks and family outings, the Acid range is presented as an entry-level mountain bike option for children aged 5 and up. The Acid 240 models use 24-inch wheels, with the Acid 240 SLX described for ages 7 to 9 and the Acid 240 Disc for ages 7 to 10. Age bands are a starting point; fit and riding confidence still matter.

For rougher trails, look at the intended terrain and the child’s control. The CUBE Stereo 240 ONE has 24-inch wheels and offers a trail-oriented alternative to a straightforward all-rounder. A mountain bike can suit mixed surfaces, while a dedicated trail bike is aimed at more technical off-road riding. Consider where the bike will be used most, rather than choosing by appearance alone.

Gravel and cyclocross models suit a different kind of adventure. The CUBE Nuroad Rookie is a cyclocross bike for children aged 9 and up, with 40 mm Schwalbe tyres. Its intended use makes it worth considering for mixed-surface rides, rather than treating it as a small mountain bike. For dirt-jump riding, the CUBE Flying Circus 240 has a singlespeed setup. That simpler format is specifically distinct from geared models such as the Acid 200, which has 7-speed gears.

• Everyday paths: compare the Acid mountain-bike range with your child’s fit and experience.
• More technical trails: consider a trail-focused option such as the Stereo 240 ONE.
• Mixed surfaces: assess whether the Nuroad Rookie’s cyclocross purpose matches planned rides.
• Dirt jumps: consider whether the Flying Circus 240’s singlespeed setup suits the riding.

Choosing amongst kids’ bikes is easier when the terrain comes first. Once you’ve identified the likely riding style, compare wheel size, model purpose and fit together. A bike built for jumps or technical trails may be less suitable for a child whose usual rides are family paths.

Saddle height and standover clearance

Use your child’s inseam as a practical starting point, then check how they stand over the frame. CUBE recommends around 3-5 cm of space between a child’s inseam and a kids’ bike’s top tube. This clearance gives room to stand with both feet on the ground when stopping. It’s a useful fit check, but it doesn’t replace trying the bike in person.

Measure the inside leg in bare feet, from the floor to the point where the saddle would sit. Keep the measuring position consistent and record the result in centimetres. For example, the Cube Access WS XS is recommended for riders with an inside leg measurement of 65 to 72 centimetres. That model-specific range can help narrow sizing, but the child should still stand over the frame comfortably.

Check saddle height after assessing frame clearance. Have your child sit on the saddle and place their heel on a pedal at its lowest point. Their leg should straighten without their hips rocking from side to side. Then ask them to pedal with the ball of each foot on the pedal. Their knee should retain a slight bend at the bottom of the stroke for comfortable pedalling.

1. Measure the inseam with your child standing upright and feet flat.
2. Compare the measurement with the model’s sizing guidance, such as the Access WS XS range.
3. Ask your child to stand over the frame and check for the recommended 3-5 cm clearance.
4. Set the saddle, then observe their leg position while pedalling.

Don’t use age alone to decide whether a bike fits. Children of the same age can have different inseam measurements, and Cube frames can have different proportions. If the saddle is set correctly but your child still struggles to reach the ground or feels stretched towards the handlebars, reassess the frame size. A bike should feel manageable not only while stationary, but also when starting, stopping and turning.

Kids bike

Children’s bikes come in a range of wheel sizes. Listed children’s wheel options include 12, 16, 18, 20, 24 and 26 inches. Use wheel size as a first guide, not a final verdict: a child’s height, inseam and confidence also affect how manageable a bike feels. CUBE’s height recommendations start at 85 cm, with guidance continuing through 130 cm and above.

For a child beginning to balance, a balance bike can be a useful starting point. CUBE says its range includes balance bikes for children from 2 years old. The Cubie 120 Walk’s age guidance and wheel size offer a concrete starting point, but the child should still be able to sit comfortably and move the bike independently.

As pedalling becomes the next step, compare the Cubie models by wheel size and age guidance. The Cubie 160 is a 16-inch pedal bike for ages 4 to 5. The Cubie 180 SLX has 18-inch wheels and is intended for ages 4 to 6. These overlapping age bands show why age alone cannot settle the choice. Compare the child’s measurements with the frame, then observe how easily they start, stop and steer.

For older or taller children, CUBE’s recommendations extend beyond the smallest wheel options. The wider listed range reaches 29 inches, while the children’s sizes include options through 26 inches. Check the specific model’s sizing information alongside your child’s height and inseam. A larger wheel is not automatically the better choice if the frame feels difficult to manage.

• Match the model’s intended stage, balance bike or pedal bike, to the child’s experience.
• Use height and inseam alongside age guidance when comparing sizes.
• Observe starts, stops and steering during a short, controlled test ride.

Once you’ve narrowed the size and riding stage, browse kids’ bikes to compare suitable options.

The Cycle Centre: Kids bikes

The Cycle Centre offers kids’ bikes, including Cube models, for families weighing up their options. If you’ve compared riding styles and sizing guidance but remain unsure which type suits your child, explore the range with their needs in mind. Consider where they plan to ride, their confidence on a bike and the fit checks you’ve made.

That context can help you focus on relevant options, whether you’re looking for a first pedal bike or a model for more adventurous rides. The Cycle Centre also supports Bike to Work, Cycle to Work and Ride to Work purchases, separate from choosing a child’s bike.

Set your child up for their next ride

A bike can become part of how a child explores, learns and gains confidence outdoors. Match the model to the rides your family actually enjoys, rather than choosing for a future version of your child. Keep their preferences in the conversation: a youngster drawn to trails may be more excited by a mountain bike, while another may prefer relaxed paths and everyday outings. Their enthusiasm can help make riding an activity they want to continue.

Use what you’ve learned about Cube kids’ bikes to narrow the options, then bring your child into the decision. Their comfort and confidence matter as much as the model name. If you’d like support choosing a suitable kids’ bike, talk with The Cycle Centre about your child’s bike choice.

A well-matched bike gives every new ride room to become an adventure.

Frequently Asked Questions

Which CUBE kids’ bike is right for my child?

Choose a bike for where your child will ride most, then narrow the options by fit and experience. A child who mainly rides family paths may need a different style from one keen on off-road trails. Cube kids’ bikes cater to different riding preferences. Consider what your child enjoys, how confidently they handle a bike and whether it feels manageable during a short test ride.

Which CUBE kids bike model is best for each age and height?

Use model age guidance as a starting point, then compare your child’s measurements with the specific bike’s sizing information. For example, the Cubie 120 Walk is a 12-inch balance bike for ages 1 to 4; the Cubie 160 is a 16-inch pedal bike for ages 4 to 5. The Cubie 180 SLX has 18-inch wheels for ages 4 to 6. CUBE’s height recommendations start at 85 cm and extend to 130 cm and above.

How do I choose the correct kids bike wheel size and frame size?

Start with the model’s height guidance and your child’s inseam, then assess the frame in person. CUBE’s children’s wheel sizes include 12, 16, 18, 20, 24 and 26 inches, while the wider range reaches 29 inches. If your child falls between options, compare reach to the handlebars and ease of starting and stopping. A wheel-size label alone can’t show whether the frame suits their proportions.

What safety features and accessories should a child’s CUBE bike have?

Prioritise a secure fit, brakes your child can operate and a helmet that sits comfortably and stays in place when adjusted. Before each ride, check that the tyres are inflated, the brakes work smoothly and the chain runs properly. A bell and lights can also help with awareness and visibility where needed. The Cycle Centre offers cycling helmets and apparel to complete your child’s riding setup.
