The short version

The first five purchases
Check that every item fits the bicycle before relying on it. Mount lights where luggage and clothing cannot cover them.
- Lights suitable for the roads you use
- A lock matched to the risk and bicycle value
- A small pump and compatible spare tube
- Full-length mudguards for year-round commuting
- A pannier, basket or comfortable bag

Legal kit is only the starting point
For UK riding between sunset and sunrise, check the current lighting and reflector rules for the bicycle being used. A legal minimum does not guarantee that a light is bright enough for an unlit route or positioned where luggage cannot obscure it.
Test lights from the front and rear after loading the bike. Rechargeable lights also need a charging routine or a backup that will last the journey.
Carry only repairs you can use
A compatible tube, tyre levers and pump solve many ordinary punctures, but only if the wheel can be removed and the pump fits the valve. Practise at home before depending on the kit beside a road.
For a repair that involves brakes, steering, wheel retention or structural damage, arrange recovery or professional help rather than improvising a safety-critical fix.
