An email sent out to customers by Embark Dundee said: “We have noticed some of our GPS have not been reporting properly, and in order to ensure a safe and secure experience for all users, we have decided to recall all the bikes to our workshop and reconfigure the entire fleet.
“We aim to have the service up and running again as soon as possible.
“We will pause any pending payments and plans, and once we re-open the service your plans will be reactivated again. If you have any queries, please email our team at support@rideondundee.com.
“We sincerely apologise for any inconvenience this may cause and wish you a happy and safe festive season.”
