We are one of the largest producers of sidecars in Europe with healthy worldwide sales. The company is a unique amalgamation of the oldest and best-known sidecar manufacturer, Watsonian, and Squire, the most successful of modern producers . We place great emphasis on personal service, giving advice on both technical and practical aspects of sidecar ownership. Our depth of experience and commitment to sidecars since 1912 provides our customers with a choice of quality products that are second to none.

We make a wide range of sidecars, both classic and modern; whether you own a scooter, a tourer, a cruiser or a classic bike, we have the sidecar to match. Sidecar bodywork was originally wicker or aluminium, mounted on an ash wood frame. Today high quality glass fibre (GRP) is used, which is available in a wide range of gel-coat colours.  Alternatively we can paint the sidecar body to match your machine.

The body is mounted onto a welded, powder-coated tubular steel chassis, which carries the suspension and fittings that attach it to the motorcycle. Each frame is made to -specifications for your bike.  In some instances, a bike may require an additional sub-frame at an additional cost.
