Yes. Using the lock is a condition of your rental.
During your ride
When you start a ride, unlock the bike from the public bike stand using the combination lock code shown in the app.
If you stop for a break, you must use the lock to secure the bike to a public bike stand.
Ending your ride
At the end of your journey, you must:
Secure the bike to a public bike stand using the combination lock
Lock the bike with the same code provided in the app
Submit an end-ride photo clearly showing the bike tethered and locked to the stand
Pedal bikes
Pedal bikes use a cable lock instead of a combination code. The bike must still be securely locked to a public bike stand in the same way.
Why this matters
Locking bikes to public bike stands is a local council requirement and helps keep bikes available, accessible, and correctly parked.
Failure to lock the bike correctly at the end of your ride may result in a parking fine.
