Roberts Cycles is a custom bicycle frame building business, originally located in Selhurst near Croydon, South London, now located in East Sussex, England.

Beginning soon after World War II, Charles (Charlie) Benjamin Roberts was a frame-builder for Holdsworth, Claud Butler and Freddie Grubb. In the 1960s, he founded Roberts Cycles at the family home in Sydenham - he was joined in the workshop by his oldest son Charles, and then by his youngest son Geoff. In 1979, Charlie Roberts died unexpectedly and Charles, began managing the business (which by then had moved from Sydenham to Anerley, South London) with his brother, Geoff and Derek Bailey continuing to build frames.

The shop at Gloucester Road, Croydon was closed at the end of May 2015. Charles Roberts (Chas, the oldest son) then left the business. Roberts Cycles, relocated to the Sussex coast, where Geoff Roberts continues the family business, Roberts Cycles, building and repairing frames

Production was limited by capacity to 100 steel frames per year, and they were made in a bespoke manner to the dimensions, mass and equipment specification requirements of the customer. A mixture of Reynolds and Columbus tubing was used in construction, which was all completed in-house. Painting was originally done in house, but was then outsourced and completed to a high standart.

The range includes bicycles built specifically for competition (road race,track) recreational (tandems, tricycles, mountain bikes, touring). Bicycles bearing the name Roberts, are all hand made in Sussex, by Geoff Roberts, using steel tube sets. Complete bicycles, or frames, can be built to customer specifications, can be built to the exact specific requirements of the customer.
