Electric Bike UMotion UM33X urban Mover just stopped working. Fine one day would not work the next. Battery is charged and therefore likely to be the Controller. However Urban Mover are no longer trading and therefore I am trying to find a supplier for the controller. Can anyone help? There is no name on the controller just the following; Product Number JDW29-1 X1004010886 CE=G3M20211-1592-16
