The Avro Mobile had low seating and, to begin with, was fully enclosed. It was fitted with a 349cc Barr and Stroud engine, three-speed Albion gearbox and all-chain drive. The frame was made of sheet steel formed into a channel section, with sprung front and rear suspension. It had hub-centre steering, 12-inch disc wheels and drum brakes. Although the machine started out with a completely enclosed body, this was soon revised to resemble a scooter-type with bonnet and front screen and a seat and tail behind.
