Grandex Motorcycles

Grandex were 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 2½ hp JAP engine, belt drive and Druid forks.
  • 1910 Stanley Show Report
    Grandex Cycle Co., Ltd.
    28 Gray's Inn Road, London, W.C. Stand No. 46.
    This is a new firm to exhibit motor-cycles. The Grandex lightweight has a H.P. Jap or Precision engine, Druid spring forks, Lycett saddle and rubber belt, and Amac or Brown and Barlow carburetter. The B.S.A. free-wheel hub is fitted, Bowden brake on the front wheel, and pulley brake on the back. The retail price is 33 guinea,s, including carrier and stand. The 4 H.P. model has a Jap motor and costs the rider 8 guineas more. One town, one agent, is the Grandex simple policy.

  • 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.

2¼ h.p. GRANDEX-PUP.

AN exceedingly handy little lightweight is the 1915 Grandex-Pup, which we recently had an opportunity of inspecting at the Grandex Co.'s showrooms at 86, Gray's Inn Road, W.C. The machine is fitted with the new 2¼ h.p. Precision engine, the valves of which are mechanically operated and vertical instead of horizontal as formerly, while it may be remembered that the dog clutch two-speed gear is incorporated in the crank case, the change being operated by means of a pedal.

The machine we saw was not the final model, and the next batch will be altered in various details; for example, instead of a U.H. magneto the Splitdorf will be fitted. The machine will be provided with aluminium footboards, and an improved heel-operated brake with transverse pedal will form part of the equipment. The silencer is large, and fitted with a long exit pipe so that the little machine should be fairly silent. Either Druid or Saxon Spring forks may be had to order.

The frame possesses a dropped top tube, while an excellent piece of work is the bottom bracket, which is in one piece and brazed directly on to the chain stays. A Bowden handle-bar is fitted complete with levers and wires, the latter running inside the bar and presenting a very neat appearance. The carburetter is the well-known B. and B. The machine, which is sold at quite a moderate figure, is well equipped and turned out with 2in. tyres, luggage carrier, and metal cased tool-bag.
