Founded in 1903, Zenith Motors Ltd manufactured from a premises at 101a Stroud Green Road and had a showroom at 119. They focussed on motor cycles but for a two year period between 1905 and 1906 also made cars.

Their "Gradua" variable-ratio belt drive transmission was among the first attempts to provide multiple drive ratios for a motorcycle. It proved to offer such a significant advantage to riders  in competitive racing that Zeniths with Gradua gears, like the model pictured above,  were banned from many competitions. Zenith capitalised on this ban, adding the word "Barred" to their advertising and logo.

The company's first model was the unusual Bi-car was launched in 1903.

Google Maps satellite view suggests that at least some of the workshop may still survive today.
