Swan was an electric tricycle produced by them in 1909.
The design for the drive system appeared as a patent in 1908, under the name of C. Lassen. The machine had a single front wheel with the motor mounted above it, with the drive by shaft to bevels. The wheel was supported by semi-elliptic springs attached to a strengthened mudguard and steering was by tiller. The bodywork was constructed with a seat to take two passengers, under the seat was stored the batteries. There was also the option of a small van body. As the maximum speed was around 15mph/24kmh, it would have been intented for town use.
