Your email is critical to us so we can contact you in case of a problem, and simply to make sure that you are who you say you are. Please make sure that this is set to the best way to reach you.
We use your postal code to help give your relevant missing bike notifications, but it isn't required.
You may want to include your phone number on your missing bike poster, if your bike is ever stolen, as an additional way for others to contact you. Phone number is not required.
