TriVelox had an interesting range of addresses. In their 1937 catalogue they list addresses in Coventry, Liverpool and Highbury in London. In their 1948 advert in The Bicycle they show an address in Manchester Square in London, but by this advert, a year later, they are supposedly residing in Spennymoor in County Durham. Even for the bicycle business, that is a bad case of itchy feet.
