Stabilisers
Browse used stabilisers for sale from riders across the UK. Stabilisers are the pair of small side wheels that bolt to a child's rear axle to hold the bike upright while they learn to pedal, and most sets are made for 12in, 14in, 16in or 20in wheels. They suit parents moving a child off a balance bike onto their first pedal bike, and they come off again within months, which is why so many sets are sold on barely worn.
What are bike stabilisers and which type should I buy?
Stabilisers clamp around the rear axle behind the nuts and hold an arm out to each side, with a plastic or rubber-tyred wheel on the end. Fixed-arm sets sit at one height and are the simplest to fit; adjustable sets let you drop the wheels a few millimetres at a time as the child gets steadier, so they can be raised until they barely touch the ground before you remove them entirely. Quick-release designs let you take the wheels off for a ride in the park and put them back for the ride home. Check the axle type before you buy: sets designed for a solid nutted axle will not fit a bike with a quick-release skewer or a rear hub gear, and bikes with rear suspension or a disc caliper often have no clear space for the arms at all.
Are stabilisers better than a balance bike?
They solve different problems. A balance bike teaches a child to hold a lean and steer into it with their feet on the ground, then hands them a pedal bike they can already balance. Stabilisers skip that and teach pedalling and braking first, with balance coming last once the wheels are raised or removed. Many children get on well with a set for a few weeks on a first pedal bike, particularly if they went straight from a trike. If you are still choosing between the two routes, the wider kids' kit listings are worth a look before you commit to either.
What should I check when buying stabilisers used?
The stabiliser wheel itself is the part that goes: hard plastic wheels wear flat on one side where the child leans, and the moulded tyre can split or come away from the rim. Spin each wheel and look for a wobble, which means the small axle bolt has bent from kerb drops. Check the steel arms for a permanent bend or a crack near the bolt hole, and make sure the mounting bracket is not distorted from being overtightened. Both mounting bolts, washers and the axle nuts should be in the box, because a set missing its hardware is fiddly to make good from a spares bin. Surface rust on the arms is cosmetic; play in the bracket where it grips the frame is not.
How much should I pay for used stabilisers?
Stabilisers are cheap new, so the used price is only worth paying when the set is complete, undamaged and matches your child's wheel size. Sets that come bundled with the bike they were fitted to are usually the better buy, since you know the fit is right. Buy new if you need a specific adjustable or quick-release design, if the used set is missing its brackets, or if your child's bike has a hub gear or disc brake that needs a purpose-made bracket. A branded set from Halfords or the stabilisers supplied with a Frog or Islabikes child's bike will hold value slightly better than an unbranded universal pair, mostly because the fit is known.
Do children need pads and a helmet with stabilisers?
A helmet is worth having from the first ride, because falls happen when the wheels come off rather than while they are on. Stabilisers raise the bike slightly and can tip on a camber or a kerb, so knee and elbow pads reduce the grazes that put a nervous child off riding. Used kids' helmets are worth checking carefully for crash history, and protection such as pads and gloves is cheap to pick up secondhand because children grow out of it fast.
