Most bike problems don't appear overnight — they build up slowly until something fails at an inconvenient moment. A short check before longer rides catches nearly all of them early. Tyres: squeeze each tyre by hand before riding. It should feel firm, not squishy. Underinflated tyres wear faster, pedal harder, and are far more prone to pinch flats on potholes. Check the sidewall for the recommended pressure range. Brakes: squeeze each brake lever. It should engage firmly well before the lever reaches the handlebar, and the wheel shouldn't spin freely once a brake is fully applied. Spongy or delayed-feeling brakes need attention before, not during, a ride. Chain: a dry, rusty-looking chain wears out the chainrings and cassette far faster than the chain itself costs to maintain. A drop of bike-specific chain lubricant every couple of weeks of regular riding, wiped of excess afterward, goes a long way. Wheels: spin each wheel and watch it pass a fixed point, like the brake pad. A wheel that visibly wobbles side to side may have a loose or broken spoke and is worth having looked at before it gets worse. Bolts: a quick check that the seat, handlebar, and pedals are snug — nothing needs to be over-tightened, just not loose enough to shift under normal riding. None of this replaces a proper service, but catching a soft tyre or a dry chain early is the difference between a five-minute fix at home and a breakdown on the road.
