After 48 years in business the Colin Collins chain of bike dealers has gone into administration.
The firm has closed two of its four dealers – in Kenton and Watford – while the other two, in Harrow and Letchworth, are still open for business.
The administrator, Vantis Plc, is hoping to sell these two as going concerns.
The stock from the two closed branches has been moved to the remaining shops, and bikes owned by the company are being sold with a 15 percent discount.
Customers can still contact The Harrow dealership on 020 8861 1666 or Letchworth on 01462 483399.
Anyone interested in becoming the new owner of either one or both of the stores should contact the administrator, Vantis.
