The Chain, the Pothole and the Helmet
A 16-year-old rides a 45 km/h AM moped to a sports club 6 km away. He wears a legal helmet but has fastened the chin strap loosely, and he wears a thin hoodie, shorts and trainers. It is dry but the road has a patched section with loose gravel near a junction, and there is a pothole on his line about 30 m ahead. His rear tyre pressure is low, which he has not checked for weeks, and the chain is slack and dry. He plans to brake late for the junction and cut across the gravel to save time. He has never practised an emergency stop.
1. Assess his protective equipment and riding preparation, and explain the specific risks.

The helmet only protects if it stays on: a loose chin strap lets the helmet shift or come off in a fall, so it must be fastened snugly under the chin. A thin hoodie, shorts and trainers give almost no abrasion or impact protection; at 45 km/h a slide on asphalt causes serious skin loss, and the hands and feet are exposed. Low rear tyre pressure affects stability, grip, and handling, and a slack, dry chain can jump or snap, which can lock the rear wheel or leave him without drive. Never having practised an emergency stop means he does not know how his brakes and tyres behave at the limit. The judgement is that protective gear and basic machine checks are not optional extras; they decide how badly a mistake ends.
2. He reaches the pothole and gravel. What should he do, and what should he have done before leaving?

On the pothole, the safe response is to reduce speed early, keep the bars straight, rise slightly off the seat and grip the bars firmly so the bike can absorb the bump, and avoid braking hard over the hole or the gravel. On loose gravel, brake gently and upright, avoid sudden steering or throttle, and keep a steady line; cutting across the gravel to save time is exactly the wrong choice. Before leaving he should have checked tyre pressures, chain tension and lubrication, fastened the helmet strap, and worn proper jacket, gloves, trousers and boots. He should also have practised emergency braking in a safe place. The core lesson is that preparation and smooth inputs prevent the situation from becoming an emergency at all.
