If you return the bike late, additional charges may apply. Most rental companies have a grace period, but exceeding that may result in an extra hourly or daily fee. It's important to check the rental agreement for specific policies.

In the event of a breakdown or accident, you should contact the rental company immediately for assistance. They will provide guidance on what to do next, including whether to repair the bike or arrange for a replacement. Always ensure you have their emergency contact information on hand.
