A Saltaire-based cycle retailer is investing £1 million to open a second outlet – which will be the largest of its type in the North of England and is the firm’s biggest expansion in more than a century.

All Terrain Cycles, Yorkshire’s oldest cycling business, is planning a new 9,000sq ft unit near Wetherby that will create four new jobs and open in the run-up to the Tour de France Grand Depart in West Yorkshire this summer.

Originally established in 1907, the £3 million turnover business has a store at Salts Mill, Saltaire, as well as a thriving online business operating from a 12,000 sq ft warehouse there.

Managing director Tony Booth said: “With a heritage of over 100 years, this is our biggest ever expansion and a really exciting development for the business.

“It is particularly fitting that we are opening our second store just a month before the greatest cycle race in the world descends on Yorkshire.

“The region has an active and growing cycling fraternity which will get another boost from the Grand Depart and many enthusiasts will be delighted to find they now have one of the UK’s largest and best equipped bike stores within easy reach.”

The new store will stock more than 1,000 mountain, road and BMX bikes as well as clothing and accessories. It will also feature a workshop staffed by trained technicians able to carry out repairs and servicing.

Work is underway on the refurbishment of the unit with the first phase due for completion in May when the ground floor of the showroom and workshop will open.

Mr Booth said: “Enthusiasts want to be able to see the widest range of quality bikes before they buy, and our strategy is to invest in bricks and mortar retail units that can offer the widest choice and buying advice from expert staff as well as attractive finance options.

“Our Salts Mill superstore has proved extremely popular with customers from along the M62 corridor visiting us to see, touch and even try bikes before they purchase. With its close proximity to the A1, our new Wetherby store will increase our geographic reach and will be the largest bike store within 100-mile radius.

“We hope to replicate the success of our Saltaire unit by offering customers the same benefits of friendly, knowledgeable staff, a state-of-the-art bike fitting facility as well as a huge choice of bikes.”

All Terrain Cycles is a family business employing 20 staff. Originally trading as Riley Brothers Cycles, it operated from Crosshills until moving to Salts Mill in 2007.

The business was acquired from the Riley family by Mr Booth in 1996 and has grown from a turnover of £45,000 in 1995 to over £3m in 2013.
