Review the insurance terms and conditions:
Theft: always report theft as soon as possible. You do not have to pay an own risk in case of theft. However, you are required to report it to the police and you must still have your bicycle key.
Damage: always report damage as soon as possible. You do not have to pay any own risk in case of damage. Even if you caused the damage yourself. With the exception of deliberate misuse of the bike and the dog trailer.
Costs: the Carefree Travel package is 10% of the total rental price. The package ends automatically when you return your bike.
Cancellation: you can cancel free of charge until 4 p.m. before the rental day starts. You will be refunded the total rental cost excluding the cost of the Carefree on the road package.
Not covered: damage you cause to others with the rented bike is not covered.
For this you need private liability insurance.
