1. Practise
Like any skill, safe cycling requires practice. You need to feel balanced and confident on your bike. You also need to know how to turn and/or stop suddenly, if required. Practising in a safe place, away from traffic, is the best way to improve your skills.
2. Get the seat height right
Adjusting your bicycle seat correctly not only makes cycling more comfortable but you'll be able to go faster, for longer. You might need a parent or bike shop staff to help you get your seat right.
Start by making sure the seat is horizontal or very close to it. Then stand your bike against a fence or wall and hop on to the seat.
Apply the brakes so you don't roll away and then put your heels on the pedals. When the lower pedal is at the very bottom position, the leg pushing that pedal should be almost, but not quite straight. Get your helper to check for you and then tighten the seat into position. (Don’t pedal with your heels when riding. Pedal with the balls of your feet.)
If you're new to cycling you may want your seat slightly lower, so you can start more easily and get your feet on the ground quickly.
3. Wear safety gear
Always wear a helmet when riding. Cycling gloves are good for protecting your hands in case you fall. If you want to try long rides, sunglasses and padded shorts will make your cycling more comfortable.
If you're riding home after dark, make sure you have bright lights on the front and rear of your bike. A reflective safety vest is also a good idea.
4. Check your bike
Your bike won't handle properly if the tyres are worn out or going flat. Check your tyres and brakes before you ride.
