As far as committing offences for which points can be added to your licence or a driving ban issued is concerned, the vehicle in question needs to be either a motor vehicle or a mechanically propelled vehicle.
A motor vehicle is defined as a mechanically propelled vehicle which is intended or adapted for use on a road.
A mechanically propelled vehicle is a vehicle which can be propelled by mechanical means. It can include both electrically and steam powered vehicles.
Electric bikes will escape both definitions and be treated as a pedal cycle for the purpose of drink drive laws if the bike is legal, eg weight/power/max assist speed limits. If the bike is not legal, for example if the motor is too powerful, it will treated as one of the above, probably a mechanically propelled vehicle.
A R/C car on it's own wouldn't fall into either category. If it was modified in some way to carry a person or load by putting a seat on it, or towing a trailer on which a person could ride, then it would become a mechanically propelled vehicle.
