What a skid actually is
A skid happens when a tyre stops rolling and slides over the surface, or slides sideways, because the force asked of it is more than the grip available. Grip comes from the contact between tyre and ground. When you brake, corner or accelerate, you are using up some of that grip. Ask for too much at once and the tyre lets go.
Several things reduce the grip available: wet roads, mud, leaves, gravel, sand, ice, painted lines and metal covers, and also tyres that are worn or inflated badly. Hard braking, sharp steering and sudden changes of speed use more of it. Surfaces differ a lot, and the traction while braking you can expect on dry tarmac is quite different from the grip on a wet or loose one.
This article is general information. Skids vary with the bike, the tyres, the surface and the rider, and no advice can promise that a particular skid will be recovered. If you are practising skills, wear a helmet and protection and do it somewhere flat, quiet and traffic-free.
Rear wheel skids
A rear wheel skid is common and often less dangerous than a front one. Under braking, weight tends to shift forward, which means the rear wheel carries less load and can lock more easily, especially on a loose surface or with a hard pull on the rear brake.
If the rear wheel locks and the back end starts to slide:
- Stay calm and keep looking ahead. Tensing up and staring at the ground tends to make things worse.
- Ease off the rear brake a little. The aim is to let the wheel start turning again. Releasing completely and abruptly can make the bike snap straight, which in some cases is destabilising, so some riders suggest easing off smoothly rather than snatching it.
- Keep the bars steady. Small steering corrections are fine, but big ones tend to cause trouble.
- Look where you want to go. Vision strongly influences steering and balance.
Some riders deliberately practise controlled rear-wheel skids as a stopping technique. The article on skid stops looks at that skill, and it should be tried only on a flat, quiet surface with protection, since a skid at the wrong moment can end in a fall.
Front wheel skids
A front wheel skid is more serious. The front wheel provides most of the steering, and when it locks and slides you generally lose the ability to steer. A front-wheel lock can also tip a rider over the bars or off to the side, and it can happen very fast.
If the front wheel starts to slide:
- Release the front brake. This is the main general advice, because a rolling wheel can generally grip and steer again. Release smoothly but promptly.
- Keep the bars straight. If the front wheel regains grip while turned sharply, the bike may be thrown sideways.
- Look where you want to go and stay relaxed.
- Re-apply gently only when the wheel is rolling again.
Once the front wheel has gone, there may not be time to recover. This is why the habits before a skid matter so much. The differences between front vs rear brake use are covered elsewhere, and the main point is that the front brake has more stopping power but also more risk of a lockup if it is grabbed.
Sideways skids and cornering
Skids in a corner are often the front or rear wheel sliding outwards because the bike was leaning, braking or accelerating too much for the surface. The usual advice is similar:
- Ease off the brake. Braking in a corner takes grip away from turning.
- Reduce any pedalling force if the rear wheel is spinning.
- Resist the urge to steer harder into the slide. Look along the line you want to take.
Many cornering mistakes come from entering too fast, braking while leaning, or turning sharply on a wet or loose patch. Slow down before the corner, not in it.
Keep your eyes up and your body relaxed
When a wheel slides, the body tends to stiffen and the eyes fix on the hazard. Both make control harder. A relaxed upper body, light hands and a loose grip allow the bike to move beneath you. Looking at your intended path rather than the obstacle helps you steer smoothly. This is the same visual focus used for balance and steering at other times.
How to make skids less likely
Prevention is far more reliable than recovery.
- Brake early and smoothly. Squeeze rather than grab, and spread braking over a longer distance. This lets the load build gradually.
- Brake before turns. Slow down while the bike is upright, then release the brakes as you lean.
- Respect wet and loose surfaces. Slippery surface clues include shine on the road, leaves, painted markings, metal plates and loose gravel. Allow more room to stop. Wet road traction is generally lower than dry.
- Check your tyres. Worn or underinflated tyres reduce grip, and the maker’s instructions will give the right way to check pressure.
- Check your brakes. A quick brake test before riding catches problems early.
- Match speed to surface. Slower is usually safer on anything unfamiliar.
Practise safely
If you want to get a feel for traction limits, try gentle braking drills on a flat, quiet, dry surface away from traffic, wearing a helmet and gloves. Start at low speed, brake progressively and notice when the wheel feels as though it is about to give way. Do not practise deliberate skids on wet or slippery surfaces, and avoid experimenting with front-wheel lockups. A qualified instructor can offer better guidance than any article.
After a skid
If you skid and stay upright, take a moment to breathe, slow down and check the road around you. If you do fall, look for injuries first. A skid can also leave flat spots on the tyre or damage to the wheel, so a post-crash bike check is worthwhile after a heavy one.
Skids are a normal part of learning, and understanding them removes some of the fear. They remain a real cause of falls, and the safest approach is smooth control, appropriate speed and good judgement.
