One: fenders, before anything else
Full-length guards if your frame has eyelets, clip-on guards if it does not. Clip-ons cover about half as much and they fit any frame.
The measurement that decides fit is tire clearance, not wheel size — the gap between your tire and the fork crown, and between the tire and the seatstay bridge.
Two: lights that live on the bike
Not lights you remember to bring. A ride that starts in daylight finishes in the dark for half the year.
Two rear lights if you can, because a rear lamp failing is the one you do not notice.
Three: a way to carry things
A rear rack and one pannier covers a laptop, lunch and a change of clothes. Look for a bag that comes on and off tool-free — you will do that twice a day, every day, and a bag that takes two minutes stops being used.
Check heel clearance: a long pannier on a short rack sits where your heel swings.
Four: a lock, and a plan for where the bike goes
Measure around the stand you will actually use — through the frame, the rear wheel and the post. That figure decides the lock length, not the lock’s own dimensions.
If your insurance names a certification scheme, read it before buying.
Five: a floor pump at home
A weekly pressure check takes ten seconds and prevents most punctures. A puncture on a commute is the failure that makes people drive the next day.
Six: a bell, and the local rules
In several European countries a bell is a legal requirement, and the rules are national.
Seven: ride the route on a day off
Once, without the pressure of being anywhere. You will change something.
The questions riders ask
Backpack or panniers?
Panniers, if the bike will take a rack. The weight sits low and over the axle where it barely affects handling, and your back stays dry — which is the difference between arriving presentable and arriving damp.
What is the single change that keeps people commuting?
Fenders. Most of the water on a rider comes off their own wheels rather than out of the sky, and a wet stripe up the back is what ends the habit in November.
