Pre-Ride Safety Inspection

For your safety, always inspect the bicycle before riding. Pay special attention to the following points, as problems with these can cause accidents.

◆ Saddle height
(The seat post must extend at least 12 cm into the frame. A maximum height line is marked on the post — never raise the saddle above it.)

◆ Brakes
(Squeeze each brake lever — it should stay at least 3 cm from the handlebar when fully gripped.)

◆ Tires
(Check that neither tire is flat.)

Our team regularly patrols and repairs bicycles, but previous users may occasionally return them with the saddle too high or a tire punctured. Please check the above before every ride and choose a different bicycle if you notice any issues.
(*You will not be charged if you return the bicycle to the same port within 5 minutes of unlocking.)

Thank you for your understanding and cooperation in keeping our service safe for everyone.
