The JNR 20" is generally suitable for children with an inside leg measurement of approximately 50-60cm. It's best to check sizing charts or try the bike in person if possible.
How much assembly is required?
The bike arrives partially assembled. Professional assembly and a safety check by a qualified mechanic are highly recommended before the first ride.
Can I fit training wheels to this bike?
This bike is not designed to accommodate training wheels due to its gearing and frame geometry. It's intended for riders who are already comfortable with basic cycling.

Regular cleaning, chain lubrication, and checks on brakes and gears are essential. It's advisable to have it serviced by a professional mechanic annually.
What is the weight limit for the rider?
While specific weight limits are not provided, the bike is built with durable aluminium components suitable for typical children's riding activities. Always ensure the bike is used within reasonable limits for its intended purpose.
Can this bike be used for racing?
The JNR 20" is primarily designed for general riding, skill development, and everyday use. While lightweight, it's not a competition-grade racing bike.
Troubleshooting
Bike won't turn on
This is a bicycle, not an electronic device. Ensure the rider understands how to pedal and steer.
Gears are skipping or not changing smoothly
The gear cables may need adjustment, or the derailleur might be misaligned. This often requires a professional bike mechanic. Ensure the chain is clean and lubricated.
Brakes are not stopping effectively
Check brake pad alignment and wear. Ensure the brake cables are tensioned correctly. Clean the wheel rims where the brake pads make contact.
Tyres feel soft or flat
Check tyre pressure and inflate to the recommended PSI (indicated on the tyre sidewall). Inspect tyres and tubes for punctures.
Handlebars are loose
Tighten the stem bolts securely. If the headset is loose, it may require adjustment by a mechanic.

Setup, Compatibility & Care
Setup:
Your Boardman JNR 20" will arrive partially assembled. It is strongly recommended that a qualified bicycle mechanic completes the assembly and safety check before the first ride.

- Lubrication: Keep the chain clean and lubricated, especially after riding in wet conditions. Use a bicycle-specific chain lubricant.

- Gears: Periodically check gear shifting for smoothness and adjust if necessary. Keep the drivetrain clean.
- Tyre Pressure: Maintain recommended tyre pressure as indicated on the tyre sidewall for optimal performance and puncture resistance.
- Storage: Store the bike in a dry place, away from direct sunlight and extreme temperatures.
