Grandex were motorcycles produced from 1910 to 1916 by a company based in Gray's Inn Road, London.

1910 The first model was offered for sale. Of sleek appearance, it had a 2.5hp JAP engine, belt drive and Druid forks.

For the next few years other models appeared, fitted with JAP and Precision engines.

1913 Only Precision engines were used, except for a short period when a Green water-cooled unit was fitted.

1915 A 225cc Peco two-stroke model with two-speeds was added.

1916 Was the last year. For some time prior to this they had also been listed as Grandex-Precision.
