Buying a second-hand bicycle

A second-hand bicycle can save you a lot of money, but buying one is not as easy as it looks. Many people go to the shop, fall in love with a colour and hand over the cash. A few simple checks will help you avoid a bad deal. This guide is for people who want a bike for getting to work or school, not for racing.

First, decide on your budget and the size you need. When you sit on the saddle, your feet should touch the ground, and you should be able to reach the handlebars without stretching. A bike that is too big or too small will hurt your back, however cheap it is. If you can, take a friend who knows bikes with you.

Next, look carefully at the frame. Small scratches on the paint are fine, but cracks near the joints are a serious warning sign, so walk away if you see one. Then check the wheels. Lift each one off the ground and spin it. It should turn smoothly without hitting the brakes, and it should not wobble from side to side. Squeeze the tyres too; soft ones may just need air, but cracked ones will need replacing.

Brakes and chain are the next priority. Pull the brake levers hard. If they touch the handlebar, the cables are loose. A rusty chain is not a disaster, because a little oil can fix it, but a chain that jumps when you pedal needs to be replaced. Replacement parts are usually cheap, so you can use problems like these to bargain for a lower price.

Finally, always take the bike for a short ride before you pay. Listen for strange noises and check that the gears change easily. Ask the seller where the bike came from and whether they have a receipt, as stolen bikes are sold more often than you think. If something feels wrong, trust your instinct and move on. There will always be another bike.
