Published

Gear guide by the Mobile Bike Mechanic team, with input from Barney Swinnerton

How we chose

We chose locks that make sense for daily carrying while still being meaningfully better than a thin cable.

  • Does it solve the rider problem without adding faff?
  • Will it fit the bikes and riders most likely to need it?
  • Is the price sensible for a commuter or family rider?
  • Are the weak points clear before you click through?

What not to buy

Avoid using a cable lock as your only lock for a bike you care about. Cables are best as secondary wheel protection.

FAQs

Is a D-lock better than a cable lock?

For most commuter use, yes. A D-lock is much harder to cut than a thin cable.

Should I use two locks?

If the bike is valuable or parked for long periods, two different lock types can make theft less convenient.
