    Coventry. Stand No. 39.
    The Excelsior motor-bicycle has done much to uphold the old name during last season, and the new models may be expected to add to its fame. The standard pattern has a variable pulley giving gear variations between about 4 to 1 and 6 to 1, while a new model is introduced having a two speed gear in the back hub. The gear is of a convenient type, allowing of starting without jacking up the rear wheel, and is therefore particularly well adapted for side car work. Special attention has been paid to the mud-guarding of the front wheel, which latter is mounted in a Druid spring fork. The petrol tank has a capacity of well over a gallon, so the rider need not run dry before he can take in an even two quarts when refilling on the road. In all there are four models - the Tourist, without pedals, the cone clutch free engine type, with pedals, the 3 H.P. two-speed model, and the 24 HT. light twin Autolite, with two-speed gear, free engine and footboards. The Autolite reflectors must not be missed.

Bayliss Thomas ?

I have a Villiers engined motorcycle called a Bayliss Thomas, looks very much like an Excelsior, I think about 150 cc 2 stroke . I have never seen anything about this bike --how many were made -etc do you have any info?

  • The machine is most likely an Excelsior as their parent company is Bayliss-Thomas. Have you images, and perhaps engine and frame numbers?

Thanks for the reply .The bike is packed in the rear of my shed and is probably my next rebuild ,so i cant send any pics or numbers at this stage. I bought it as a non runner in the late 70s .Of course did the stupid thing young guys do -take the engine apart ,and never reassemble .I did store the parts properly and it will be a easy rebuild seems to be a 1955 ish model . I have not found any reference to it on the internet ,and also looking up company that used the Villiers engine .it is maroon in color and is exactly like the small Excelsior. Will make contact again when i can supply some pics and numbers .
Kind regards,
Mick Skelly
