This page deals with choosing an additional bike.

What should you consider when buying a second bike?

There may be an argument for choosing an additional bike that’s totally different from the one you already have, on the grounds that duplication is a waste of storage space, and if you’re buying another bike, it may as well be set up for a different kind of journey, or a different style of cycling.

On the other hand, a good reason for owning a second bike is to have a spare so you’re not inconvenienced if your main bike breaks down. This might be particularly important if cycling is your primary means of transport.

In either case, there are some reasons to choose a bike with key components compatible. In practice, this means the same size wheels, the same number of gears on the rear wheel and the same type of innertube valve. When these parts match, the bikes can share gear parts, innertubes, pumps and tools.

All of this secondary to the fit of the bike, of course, which is in turn a product of frame size. There’s no point in buying a bike that doesn’t fit, however temptingly cheap it may be, unless you’re buying it just as a source of spare parts.

So when choosing a second bike, look for one that fits you. If there’s still a choice after that, consider matching the following:

  • Wheel size (BSD)
  • Over-locknut width (OLN)
  • Number of gears on rear wheel (cassette or freewheel)
  • Innertube valve type (Schrader/Presta)
