24-inch convertible or a conventional pedal bike?
The Rookie 24 is built for older riders who haven't yet mastered two-wheel balance. A conventional pedal bike is the more direct choice for someone who already starts, balances and stops confidently.
| What matters |  Rookie 24 convertibleBalance first, then pedals |  Conventional pedal bikePedals from day one |
|---|---|---|
| Assumes balance? | No — it teaches that first | Yes |
| Best starting rider | Older beginner, nervous rider or late learner | Already balances confidently |
| Fit | Ages 9–13+; inseam 62–84 cm | By frame size, standover and the maker's chart |
| Feet-down learning | Starts in balance mode, feet near the ground | Pedals fitted from the start |
| Weight | 8.7 kg balance / 10.6 kg pedal | Varies by frame and components |
| Gearing | Two-speed automatic, shifts at about 11 km/h | Single-speed or manual gears |
| Brakes | Front and rear V-brakes | Varies by model |
| Rider weight limit | 120 kg | Varies by model |

Learning to ride isn't limited to one age. A correctly sized bike matters more than starting early.
Frequently Asked Questions of 24 Inch Bike
A 24 inch bike has wheels approximately 61 cm in diameter. The overall bike is 145–165 cm long. It suits riders aged 9 to 13 standing 130–155 cm tall. It is significantly larger than a 20 inch bike and approaches adult bicycle dimensions.
A 24 inch bike suits children aged 9 to 13 years. Height of 130–155 cm is the most reliable guide. Tall 8 year olds sometimes fit a 24 inch bike. Some shorter teenagers still ride 24 inch comfortably. Always confirm inseam against the bike's minimum seat height.
A 24 inch bike suits riders standing 130–155 cm tall. Inseam should fall between 53 and 66 cm. If your child's inseam is under 53 cm, a 20 inch bike fits better. If inseam exceeds 66 cm, consider a 26 inch bike.
No. Training wheels are not suitable for a 24 inch bike. They are designed for much smaller, lighter bikes. A child who needs training wheels at this size should start on a smaller wheel size and develop balance first. A balance bike approach works faster than training wheels at any age.
Yes for most teenagers. A 24 inch balance bike suits riders from around 130cm up, and many riders over 155cm ride one comfortably once the seat post is at full extension. For adult riders, or anyone taller than about 175cm, contact us with the rider's inseam before ordering and we'll confirm whether the maximum seat height works. We'd rather tell you it doesn't fit than process a return.
Nothing, they're the same product. "Run bike", "balance bike", "learn-to-ride bike" and "pedal-less bike" all describe a bike with no pedals and no training wheels, where the child powers and balances it with their feet. Australian retailers mostly use "balance bike"; UK and European brands often say "run bike".
The Kidvelo Rookie 24 is designed for exactly that. It ships as a balance bike, and the pedal set and 2-speed automatic gearing attach when your child is ready — no second bike, no new purchase, no waiting for a birthday. Most families make the switch within a few weeks of the first ride. The pedal kit is included, and the conversion is a home job with the supplied tools.

Which Age and Height Fits a 24 Inch Balance Bike?
| Age | Height | Inseam | Fit |
| 8–9 years | 130–137 cm | 53–57 cm | Fits if tall for age — measure inseam first |
| 10–11 years | 137–146 cm | 57–61 cm | Ideal fit |
| 12–13 years | 146–155 cm | 61–66 cm | Ideal fit |
| 14+ years / teens | 155 cm+ | 66 cm+ | Fits many teens — check maximum seat height with us |
Fit Tip: Wheel size is set by leg length, not birthdays. Find your child’s height in the table, then confirm inseam before you order.
A tall 9 year old often fits a 24 inch balance bike comfortably. A smaller 12 year old may ride better on the 18 inch balance bike for ages 5–8.
Every wheel size and height range is set out in our kids bike size guide and if your child sits between two sizes, send us their inseam and we’ll tell you which one to buy before you spend anything.
Why an Older Child Still Benefits From a Balance Bike
Training wheels teach pedalling but never teach balance, which is why children who start late can stall on them for years. Taking the pedals off isolates the one skill that matters, staying upright and steering — and most 9 to 13 year olds pick it up within a few sessions rather than a few seasons.
The reason a full-size 24 inch frame matters at this age is dignity. An older rider will not persist on a toddler bike in front of their friends. A large balance bike puts them at the right height, on the right wheel size, learning the same way our balance bikes for older kids and adaptive balance bikes for special needs and autistic kids are designed to work.
Once balance clicks, the pedals go back on, see our full range of convertible balance bikes for how the transition works.
Which Wheel Size Fits your Child?
Not sure if your child needs a 24 inch bike? Use this table first.
| Wheel Size | Age (guide) | Height Range | Inseam Range | Best For |
| 12 inch | 2–4 yrs | 85–100cm | 30–40cm | First balance bikes |
| 14 inch | 3–6 yrs | 95–110cm | 36–45cm | Confident toddlers, balance-to-pedal |
| 18 inch | 5–8 yrs | 110–125cm | 44–52cm | School-age learners |
| 16 inch | 4–6 yrs | 100–115 cm | 38–48 cm | First pedal bikes |
| 20 inch | 6–9 yrs | 115–130 cm | 45–53 cm | Growing confident riders |
| 24 inch | 9–13 yrs | 130–155 cm | 53–66 cm | Active tweens, trail riders |
Height beats age every time. A tall 8 year old can fit a 24 inch bike. A shorter 12 year old may still ride a 20 inch comfortably. Always measure inseam, not just birthday, before buying.
Why the 24 inch wheel size is a turning point in kids cycling
The step from 20 inches to 24 inches is the biggest transition in kids cycling. Frame geometry lengthens. Gearing complexity increases. The riding demands shift from playgrounds to real terrain.
A 24 inch mountain bike handles proper singletrack, gravel trails, and pump tracks. Components at this size, disc brakes, indexed 7-speed shifting, quality front suspension, are often shared with entry-level adult mountain bikes. This is genuine equipment, not a toy with bigger wheels.
The sections below cover what your child rides once the pedals go on. A convertible 24 inch balance bike has to meet the same standard as a pedal bike, because within a season that is exactly what it becomes.
What weight should a 24 inch kids bike be?
Frame material matters most here. Aluminum frames keep a 24 inch kids bike under 10–11 kg. A heavy steel frame in this size class can add 2–3 kg, that is significant when a child is carrying and maneuvering the bike on trails.
Target weights by category:
- 24 inch kids mountain bike: 9–11 kg (aluminium, front suspension)
- 24 inch general-purpose bike: 9–10 kg (aluminium, rigid)
- Budget steel 24 inch bikes: 12–14 kg (avoid for trail riding)
The best 24 inch youth mountain bikes stay under 10 kg. Lighter bikes build confidence faster, especially on technical terrain.
24 inch mountain bike vs 24 inch kids bike, what is the difference?
Not all 24 inch bikes are the same. Here is how the main types compare.
| Feature | 24 inch kids bike (general) | 24 inch mountain bike |
| Tyres | Smooth or semi-slick | Wide, knobbly (2.1–2.4″) |
| Suspension | Rigid fork | Front suspension (50–80 mm travel) |
| Brakes | V-brakes or caliper | Mechanical disc or hydraulic disc |
| Gearing | 1–7 speed | 7–21 speed indexed |
| Best terrain | Paths, flat trails | Singletrack, gravel, pump tracks |
| Typical weight | 9–10 kg | 10–11 kg |
Choose a 24 inch youth mountain bike if your child rides off-road, visits trail parks, or wants to progress to technical terrain. Choose a standard 24 inch kids bike for school, flat paths, and casual weekend rides.
What about a 24 inch girls bike?
A 24 inch girls bike differs from equivalent boys models only in colour and saddle shape. Frame geometry at this wheel size is now converging across gender lines, fit matters far more than labelling. Measure inseam. Check minimum seat height. Ignore the colour marketing. The right bike is the one that fits.
What to look for when buying a Children’s 24 inch bike
Use these six criteria to compare any 24 inch children’s bike before purchasing.
Frame material: Aluminium is the correct choice at this wheel size. It weighs under 11 kg and does not rust. Avoid steel frames for trail riding, the extra weight limits what young riders can do on hills and technical sections.
Front suspension (for mountain bikes): Look for 50–80 mm of suspension travel. Anything less does little on real terrain. Quality forks use preload-adjustable springs, lockout is a bonus but not essential at this age range.
Brake type: Mechanical disc brakes are the current standard for 24 inch youth mountain bikes. They work in mud, wet conditions, and on descents. V-brakes are acceptable on general-purpose bikes used on dry paths. Hydraulic disc brakes appear on premium models and offer the lightest lever pull, useful for smaller hands.
Gear range: A 7-speed drivetrain handles Australian terrain well at this age. 21-speed setups exist but are unnecessary unless your child rides steep, technical climbs regularly. Indexed shifting (Shimano or equivalent) is non-negotiable unindexed shifting is hard for kids to manage and falls out of adjustment constantly.
Standover height: Measure your child’s inseam and check the bike’s minimum standover height before ordering. The child should stand flatfoot over the top tube with 2–3 cm of clearance. If standover height is listed on the product page, use it. If not, contact us before purchasing.
Tyre width and tread: General-purpose 24 inch bikes: 1.75–2.0 inch semi-slick tyres. Mountain bikes: 2.1–2.4 inch knobbly tyres. Wider tyres add grip and absorb trail vibration, but slow the bike on sealed paths. Match tyre type to where your child actually rides.
How big is a 24 inch bike, and will it fit in the car?
A 24 inch bike is considerably larger than anything below it. Here are the physical dimensions you need to know.
- Overall length: 145–165 cm
- Saddle height (mid-extension): 65–75 cm
- Handlebar width: 55–65 cm
- Wheel diameter: ~61 cm (24 inches)
Can a 24 inch bike fit in a car?
Yes, in most Australian vehicles with the front wheel removed and the rear seat folded flat.
| Vehicle type | Fit with wheel on? | Fit with the wheel off? |
| Station wagon | Usually yes | Yes |
| SUV / crossover | Sometimes | Yes |
| Hatchback (Corolla, i30) | No | Yes — rear seat folded |
| Small sedan | No | Tight — boot only |
For regular trail riding, a rear bike rack or roof rack is the practical long-term solution. Fits two bikes easily and eliminates the wheel-off routine.
24 inch bikes, common questions answered
Training wheels are not suitable for a 24 inch bike. They are designed for bikes under 20 inches. A child who needs training wheels at this wheel size should step back to a smaller bike and build balance and confidence first. A balance bike approach works faster than training wheels at any age.
All 24 inch bikes in this collection comply with Australia’s mandatory bicycle safety standard (AS/NZS 1927). View our shipping and shipping and delivery policy for lead times on larger bikes. Browse bike accessories for kids helmets, gloves, and hydration packs suited to active tweens.
