pre war those autocycles were generically known as Wilfreds. Beloved of district nurses and vicars, if you get to ride it turn your collar back to front.
They all looked virtually the same. My very first 'powered' two wheeler was an Excelsior Autobyke. I never got it going but learnt a lot from it, like bikes won't run without sparks, or piston rings and on paraffin the tank.
It gave me and my brother some useful exercise pushing it up and down the garden in the hope it might start one day.
