Why a second-hand folding bike?

• Ideal for public transport commuters. A folding bike counts as hand luggage and may be taken on the train for free, provided it is folded — even during rush hour.
• Compact storage. Perfect for small apartments, hallways, or under your desk at the office.
• Flexible use. Useful as a second bike alongside your main bike, for example, for vacations or in a camper van.

Taking a folding bike on the train: the rules

According to the official NS terms and conditions, a folded bike may be taken on the train for free at any time of day — including rush hour. However, conditions apply: the bike must remain compactly folded for the entire journey (maximum 45 x 86 x 80 cm, width x length x height) and must not obstruct the flow of passengers. The same rules as for hand luggage apply on buses and trams. You can find more details at the Cyclists' Union (Fietsersbond).

What should you look for in a second-hand folding bike?

• Folding mechanism. Test whether the hinge locks smoothly and securely — this is the part that wears out the most and is the most important for your safety.
• Wheel size. Folding bikes often have smaller wheels (16-20 inches), which makes the riding experience different from a regular bike. This is normal and you will get used to it quickly.
• Weight. If you need to carry the bike often (stairs, train), pay attention to the weight — aluminum models are lighter than steel ones.
• Gears. Some folding bikes have only 1 gear, others have several — choose what suits the terrain where you cycle.
• Frame number. When buying from a private seller, always check if the bike is registered as stolen via Stop Heling or the RDW Bicycle Theft Register.
