Best bike helmets for folding bikes in 2026

For a folding bike, everything revolves around portability and protection during transport. A good carry cover or transport bag like the Brompton B-Bag or Vincita Sightseer keeps your clothes clean while carrying on the train and protects the bike from scratches. Because your folding bike often travels with you, a lighter lock such as the Hiplok Z LOK or ABUS Bordo Lite 6055 will do — heavy hardware slows folding and makes the bike awkward. A small multitool with a few Allen keys is handy on the go, as is a mini pump. Compact LED battery lights (Knog Plus or Cateye Volt) are ideal because they are removable, reducing theft risk. A special folding-bike saddle cover helps with wet trains. For luggage, Brompton's front block system with an S-Bag or C-Bag is brilliantly designed: the bag does not turn with the steering. Tern owners are well served by the Tern HoldOn bungee or Ortlieb Fork-Pack. Finally, a pedal strap pouch or plastic bag to shield potentially oily pedals from your trouser leg.
