Buying and Selling Preloved Children’s Bikes and Scooters

Children can outgrow bikes and scooters quickly, so suitable preloved options may provide good value and give useful equipment another life.

These items still need careful checks. A cracked frame, worn brake, loose wheel, damaged folding lock or incorrect size can make a bike or scooter unsuitable for safe use.

This guide explains what buyers and sellers should check before a children’s bike or scooter is listed, purchased, collected, delivered or used.

Trusted UK Cycling, E-Bike and E-Scooter Links

• UK Product Safety Alerts, Reports and Recalls
• The Highway Code rules for cyclists
• Bikeability cycle training
• GOV.UK electric-bike rules
• GOV.UK rental e-scooter trial rules
• Child Accident Prevention Trust falls and cycle-safety guidance

Identify the Exact Product

Before buying or selling, find:

• Manufacturer or brand
• Model
• Wheel size
• Frame size where relevant
• Recommended age, height or weight range
• Serial or batch number
• Approximate age

Labels may appear on the frame, underside, stem, deck or near the rear wheel.

Check Official Product Recalls

Search the official UK Product Safety Alerts, Reports and Recalls database.

Use the brand, model, batch number and product category.

Do not buy, sell, give away or use an affected product contrary to the official instructions.

Find the Manufacturer’s Instructions

The correct manual may confirm:

• Assembly
• Wheel and handlebar fitting
• Brake adjustment
• Folding operation
• Tyre pressure
• Child height or weight limits
• Maintenance
• Approved replacement parts

Use instructions for the exact model where possible.

Check the Correct Size

A bike or scooter should suit the child’s current height, ability and the manufacturer’s stated limits.

For bikes, consider:

• Wheel size
• Frame size
• Seat height
• Reach to the handlebars
• Ability to operate the brakes
• Ability to get on and off safely

For scooters, consider:

• Handlebar height
• Deck size
• Weight limit
• Steering type
• Number and size of wheels

Do not buy significantly larger equipment only for the child to “grow into”.

Inspect the Frame

Check for:

• Cracks
• Bends
• Rust or corrosion
• Damaged welds
• Loose joints
• Unapproved drilling or alterations
• Repairs

Do not use or sell a bike or scooter with structural damage or an uncertain frame repair.

Check the Fork

On a bike, inspect the front fork for:

• Bends
• Cracks
• Loose headset movement
• Damage around the wheel attachment

A bent or damaged fork can affect steering and stability.

Check the Handlebars and Stem

Confirm that:

• The handlebars are straight
• The stem is secure
• There is no excessive movement
• Grips are present and secure
• Height adjustment limits are respected

Do not raise handlebars beyond the marked safe insertion limit.

Check Steering

Turn the handlebars fully in both directions.

Check that:

• Movement is smooth
• There is no binding
• The front wheel aligns correctly
• The headset is not loose
• Cables do not obstruct movement

Inspect the Wheels

Check every wheel for:

• Secure attachment
• Cracks
• Bends
• Loose spokes
• Side-to-side movement
• Damaged bearings
• Worn wheel surfaces

Spin each wheel and watch for wobbling or rubbing.

Check Tyres

Inspect for:

• Cracks
• Bald areas
• Bulges
• Cuts
• Embedded objects
• Incorrect pressure

Use the tyre and manufacturer guidance for pressure.

Check Brakes

Test every brake.

Check:

• Brake levers
• Cables or hydraulic lines
• Brake pads
• Disc or rim contact
• Rear foot brake on scooters
• Stopping action

The child should be able to reach and operate the brake controls.

Do not sell or use a product with unreliable brakes.

Check the Chain and Gears

For chain-driven bikes, inspect:

• Chain condition
• Chain tension
• Chain guard
• Gears
• Derailleur
• Crank and pedals

Look for rust, stiff links, slipping, bent parts and missing guards.

Check the Pedals and Cranks

Confirm that:

• Pedals turn freely
• Pedals are not cracked
• Crank arms are secure
• There is no excessive side movement

Check the Saddle

Inspect:

• Saddle condition
• Seat post
• Clamp
• Height adjustment marks

Do not raise the seat post beyond the minimum insertion mark.

Check Stabilisers

If stabilisers are included, confirm:

• Both are present
• Fixings are secure
• Wheels turn normally
• They match the bike
• No bracket is bent

State clearly whether stabilisers are included or have been removed.

Inspect Scooter Decks

For scooters, check:

• Deck for cracks or bends
• Grip surface
• Rear brake
• Wheel mounting points
• Sharp edges

Check Folding Scooters

Inspect the folding mechanism carefully.

Check that:

• It opens and closes correctly
• The lock engages fully
• Release levers are not damaged
• There is no excessive movement at the joint
• The stem does not collapse unexpectedly

Do not use or sell a scooter with an unreliable folding lock.

Check Adjustable Handlebars

Confirm that:

• Adjustment holes or clamps are undamaged
• Both handlebar sides lock at the same height
• The stem remains within marked limits
• There is no twisting or slipping

Check Three-Wheel and Lean-to-Steer Scooters

Inspect:

• Front wheel assemblies
• Steering mechanism
• Deck
• Rear brake
• Handlebar lock

Check that the product returns to a neutral steering position where designed.

Electric Bikes and Scooters

Electric products need additional legal, battery, charging and road-use checks.

Electrically Assisted Pedal Cycles

GOV.UK states that a person must be at least 14 to ride an electrically assisted pedal cycle, or EAPC. To remain an EAPC, the cycle must meet the current pedal, motor-power, assistance-speed and marking rules. A product outside those rules may be treated as a motorcycle or moped with separate registration, licensing, insurance and helmet requirements.

Check the current GOV.UK electric-bike rules before buying or selling.

Electric Scooters

As of July 2026, GOV.UK states that privately owned electric scooters cannot legally be used on public land. Government-trial rental e-scooters have separate rules, including licence and area restrictions, and are not children’s toys.

Do not describe a private e-scooter as road-legal or suitable for a child to ride on public roads, cycle lanes or pavements. Check the current GOV.UK e-scooter guidance.

Battery and Charger Checks

• Use the correct original or manufacturer-approved charger
• Check the battery casing for swelling, impact or heat damage
• Do not charge a damaged battery
• Disclose battery age, replacement and range limitations accurately
• Check carrier restrictions before posting any lithium battery

Check Helmets Separately

A helmet is a safety-critical item and should not be treated as an ordinary accessory.

A preloved helmet may be unsuitable after an impact even when damage is not obvious.

Check:

• Impact history
• Manufacturer replacement guidance
• Shell
• Internal liner
• Straps and buckle
• Fit

Where the history is unknown, do not buy, sell or use the helmet.

Buying a Bike or Scooter Online

Before purchasing, check:

• Exact model and size
• Child height or weight range
• Frame and fork condition
• Brakes
• Wheels and tyres
• Steering
• Chain and gears where relevant
• Folding mechanism
• Collection or delivery options

Questions Buyers Should Ask

• What is the exact wheel or frame size?

• Test folding locks
• Confirm all included accessories

Use a Controlled Test Area

Where appropriate, test the product in a safe, flat area away from traffic.

A child should not test equipment that is visibly damaged, incorrectly sized or not yet checked by an adult.

Consider Professional Servicing

A qualified cycle technician may be appropriate where:

• Brake condition is uncertain
• Wheels wobble
• Gears do not shift correctly
• Bearings are loose
• The bike has been stored for a long time
• The seller cannot explain previous repairs

Selling Bikes and Scooters

A useful listing should include:

• Brand and model
• Wheel and frame size
• Recommended height or weight range
• Condition
• Brake condition
• Tyre condition
• Chain and gear condition
• Folding mechanism condition
• Repairs or replacement parts
• Included accessories
• Collection or delivery details

Use Kidora’s Correct Condition Labels

Kidora currently uses:

• New
• Like New
• Very Good
• Good
• Well Used

Select the closest condition and describe scratches, rust, worn tyres, replacement parts and mechanical faults separately.

Photograph Bikes and Scooters Clearly

Include photographs of:

• Full left and right sides
• Frame and fork
• Handlebars and stem
• Brakes
• Wheels and tyres
• Chain, gears and pedals
• Deck and folding mechanism
• Size and model labels
• Every scratch, rust area, repair or fault

Describe Repairs and Servicing

State:

• What was repaired or replaced
• When the work was completed
• Whether a cycle technician completed it
• Whether receipts are available

Do not describe an item as recently serviced without a reasonable basis.

Pricing Bikes and Scooters

Consider:

• Current retail price
• Brand and model
• Size
• Condition
• Brake and tyre condition
• Required servicing
• Included accessories
• Seasonal demand
• Comparable UK listings

Reduce the price to reflect genuine maintenance needs, but do not sell unsafe equipment as ready to use.

Seasonal Demand

Bikes and scooters may attract more interest:

• In spring
• Before summer holidays
• Before birthdays
• Before Christmas

Do Not Sell Unsafe Equipment Cheaply

A low price does not make the following suitable for sale:

• Cracked frames
• Bent forks
• Unreliable brakes
• Loose wheels
• Broken folding locks
• Unresolved recalls

Packaging and Delivery

Delivery may require partial dismantling.

The seller should:

• Follow manufacturer instructions
• Protect frame and fork
• Secure handlebars and pedals
• Protect wheel axles
• Keep small fixings in a labelled bag
• Use strong packaging
• Use tracked delivery
• Retain proof of postage

Large bikes may be more practical for local collection.

Local Collection

For collection:

• Keep arrangements in Kidora messages
• Confirm the order status
• Allow reasonable inspection
• Demonstrate brakes and folding mechanisms where practical
• Mark the order as collected after handover

Frequently Asked Questions

How do I know whether a bike is the right size?

Check the manufacturer’s height guidance, wheel and frame size, seat adjustment and whether the child can reach the handlebars and operate the brakes comfortably.

What should I test at collection?

Inspect the frame and fork, test brakes, spin the wheels, check steering, inspect tyres and test any folding mechanism.

Can a bike needing repairs still be sold?

Minor maintenance needs may be disclosed and reflected in the price, but do not sell structurally damaged or unsafe equipment as ready to use.

Should I buy a preloved helmet with the bike?

Only when its complete impact history is reliably known and the manufacturer’s replacement guidance confirms it remains suitable. Unknown-history helmets should not be reused.

Can bikes and scooters be listed as FREE on Kidora?

Yes. FREE items are collection-only and have no Buyer Protection fee, but they must still be suitable, accurately described and safe for continued use.
