Folding bike 2026: comparison for multimodal commuting

Folding bike: the ideal multimodal companion

The folding bike is the solution for anyone combining bike + train, bike + metro, or bike + car. You fold, board the transport, unfold, ride. But not all folders are equal. This comparison helps you choose.

Why a folding bike?

  • Multimodal: allowed on trains, metros and buses (folded) at no extra charge
  • Anti-theft: keep it with you at the office or restaurant
  • Apartment: fits in a closet
  • Car: fits in any trunk

Key criteria

1. Weight

Weight is the #1 criterion. You'll carry this bike up metro stairs, on platforms, through corridors. Every kilogram matters.

  • Under 10 kg: premium (Brompton P Line, Tern Verge)
  • 10-12 kg: standard (Brompton C Line, Tern BYB, Dahon)
  • 12-14 kg: heavy (Decathlon, budget folders)
  • Over 14 kg: too heavy for daily use

2. Folded size

Brompton is unbeatable: 58 × 56 × 27 cm, about the size of a large backpack. The Tern Verge (20" wheels) is 30% larger folded.

3. Ride quality

Small wheels (16") roll less smoothly than large ones (20"). But Brompton compensates with refined geometry. In the city over 5-10 km, the difference is minimal.

20" (Tern, Dahon)Very goodVery goodOK

4. Fold/unfold speed

  • Brompton: 15-20 seconds, very intuitive after 2-3 tries
  • Tern: 10-15 seconds, different mechanism (frame halves)
  • Dahon: 15-20 seconds, classic system
  • Decathlon Tilt: 20-30 seconds, less refined

Train rules

  • Folding bike in a bag: free, considered luggage (most European rail operators)
  • Bag often required on high-speed trains (TGV, ICE, Eurostar)
  • Brompton fits in the official Brompton bag → free on most trains
