The right bicycle spare part can keep a well-used children’s bike rolling for longer. Xchange Sports Australia offers selected genuine replacement parts and upgrades for compatible Kidvelo Rookie and Strider bikes, with current availability shown on each product page.
Whether you are checking parts for a 12, 14, 16, 18, 20, 24 or 26-inch bike, start with the bike’s brand, model and component specifications. Wheel size helps identify tyres, tubes and complete wheels, but it does not confirm that every brake, chain, pedal, axle or clamp will fit.

Bike-Part Size Guide: 12, 14, 16, 18, 20, 24 and 26 Inches
Use this as a compatibility checklist, not a promise that every listed wheel size is currently stocked. The complete tyre code or manufacturer specification remains the deciding factor.
| Bike Size | What to Confirm Before Ordering |
|---|
| 12-inch | Full tyre marking, bike model, axle type and whether the bike is a balance bike or pedal bike. |
| 14-inch | Exact model, tyre diameter and width, hub or coaster-brake system and wheel attachment method. |
| 16-inch | Tyre code, rim and valve type, brake system, chain specification and pedal thread. |
| 18-inch | Bike model, wheel and hub type, tyre width, brake configuration and drivetrain compatibility. |
| 20-inch | Whether it is a BMX or standard kids’ bike, plus the tyre code, axle, brake and gearing specifications. |
| 24-inch | Complete tyre size, hub and axle type, brake format and the number and type of gears. |
| 26-inch | Full component specifications because tyres, rims, hubs, gears, brakes and axles vary widely across 26-inch bikes. |
Wheel Size Is Important—but It Is Not Enough
A label such as “16-inch bike part” describes only one part of the fit. Two bikes with the same wheel diameter can use different tyre widths, hubs, axles, brakes and drivetrains.
- Tyres and tubes: match every number printed on the tyre sidewall, not the wheel diameter alone.
- Wheels and axles: confirm the bike model, axle diameter, axle length, hub width and attachment system.
- Brake parts: match the existing brake type, mounting system and manufacturer specification.
- Chains and gears: confirm the drivetrain type, chain width and number of rear gears.
- Pedals and clamps: check the thread, diameter and model-specific dimensions before purchase.
Current Genuine Kidvelo and Strider Spare Parts
The current collection focuses on selected model-specific parts rather than a universal catalogue. Product availability can change, so check the live listing before ordering.
What Information Should You Check Before Ordering?
A few details can prevent an incorrect spare-parts order. Photograph the existing part before removing it and keep any washers, spacers or fasteners in their original sequence.
- Bike brand, model name and approximate year
- Wheel size and full tyre-sidewall marking
- Part number or manufacturer reference, when shown
- Clear photos of the existing component and mounting position
- Relevant measurements in millimetres
Australian Bicycle Safety and Replacement Parts
Australia’s mandatory bicycle standard applies to complete pedal bicycles within its stated scope. It covers design and performance areas including braking systems, control cables, drive chains, fasteners, pedals, reflectors, steering systems and wheels.
This does not mean every replacement part sold separately carries its own AS/NZS 1927 certification. A replacement part must be compatible, suitable for its intended use and installed correctly so the repaired bike remains safe to ride.
Read the official
Australian Government bicycle mandatory standard.
If you are uncertain about work involving brakes, wheels, steering or the drivetrain, use a qualified bicycle mechanic.
When Should Kids’ Bike Parts Be Replaced?
There is no single replacement schedule for every bike. Riding frequency, rider weight, storage and weather exposure all affect component life. Inspect the bike regularly and follow the bike and component manufacturers’ service limits.
- Tyres: replace when tread is excessively worn or the casing shows cracks, bulges, cuts or exposed material.
- Inner tubes: replace when the valve is damaged or repeated failures make repair unreliable.
- Brake pads: replace at the maker’s wear limit or when correct adjustment no longer delivers reliable braking.
- Brake cables: replace frayed, corroded, kinked or stiff cables before the next ride.
- Chains: inspect for damage, stiff links, corrosion and excessive measured wear.
- Grips, pedals and saddles: replace when damage, looseness or loss of grip affects safe control.
A Quick Kids’ Bike Safety Check Before Every Ride
Check the bike again after fitting any replacement part. The rider should not use it until every affected component is secure, correctly adjusted and operating normally.
- Tyres and wheels: confirm suitable pressure, secure attachment and free rotation.
- Brakes: squeeze each control and make sure the bike stops reliably.
- Steering: check that the handlebars are aligned and secure.
- Drivetrain: ensure the chain, pedals and gears move without binding or excessive looseness.
- Safety equipment: check the bell, reflectors and any required lights.

Frequently Asked Questions About Bicycle Spare Parts
Does the same wheel size guarantee that a part will fit?
No. Wheel size is useful for narrowing the search, but tyre width, model, hub, axle, brake and drivetrain details can still differ.
Can a generic bicycle part replace a genuine part?
Only when its dimensions, specification and intended use match the bike manufacturer’s requirements. Do not substitute a safety-critical component based on appearance alone.
Should I repair the bike myself?
Simple items may be manageable when the manufacturer supplies clear instructions. For brakes, steering, wheels, axles or drivetrain work, use a qualified bicycle mechanic if you are not confident about the installation or final checks.
What should I send Xchange Sports for a compatibility check?
Send the brand, model, wheel size, part number if available, measurements and clear photographs of the existing component and its mounting position.
