| United States | No federal law; many states require helmets for children and teens, and some cities add rules | Varies by state or city |
| Australia | Helmets required for cyclists | Fines, set by each state and territory |
| South Korea | Helmet duty for riders and passengers since 28 Sep 2018 | None for bicycles |
Korea: a duty without a fine
Korea’s amended Road Traffic Act made helmets a duty for all bicycle riders and passengers from 28 September 2018, but there is no penalty for not wearing one on a bicycle. Electric kick scooters and throttle e-bikes are different: they count as personal mobility devices, and riding one without a helmet carries a 20,000 won fine. Pedal-assist e-bikes follow the bicycle rule (see pedal-assist vs throttle).
Reasons to wear one anyway
- Claims after a crash — insurers and courts may look at safety equipment. How much it matters depends on the case.
- Speed — even a 15–20 km/h commute means a fall from head height plus forward speed.
- Group rules — clubs, group rides and many events will not let you start without one.
Making it a habit
“It is only around the corner” is the most common reason riders skip it. Hang the helmet on the handlebars or by the door so you cannot leave without seeing it. Bike-share users can keep a folding helmet in their bag.
Only log helmet days
Make a personal rule: you only enter a ride in Daily Bike Log if you wore a helmet. Wanting to keep the streak going then pulls the helmet habit along with it. Streak and Best streak sit on the Log tab.
