Three bikes worth £12,000 altogether were stolen from a house near Innerleithen yesterday.
The cycles were stolen at about 12.10am from the driveway of a property on the B709 near Traquair Kirk.
They were taken from the rear of a vehicle parked in the driveway, put in another vehicle and driven away.
The most expensive of the bikes stolen, valued at £7,000, was a custom-built men’s Evil Insurgent, with full suspension, a black carbon 20in frame and Burgtec and Hope accessories.
The other two bikes taken, valued at £2,500 apiece, were boys’ Rocky Mountain Thunderbolts with black 14in frames with white details, full suspension and upgraded Shimano SLX components.
Both the boys’ bikes are registered with Peebles-based cycle security company Veloeye, potentially making them easier for police to trace.
Inspector Robbie Noble, of Melrose police station, said: “These thefts occurred at an address that is in a remote location and not directly accessible to the public.
“I’m urging members of the public to be aware of any suspicious activity in their area, including noting any vehicles, especially larger ones that could be used to carry stolen bikes.
“If anyone has information that could assist police in their investigation, please do not hesitate to get in touch as soon as possible.

Anyone with information on the whereabouts of the bikes is asked to call Police Scotland on 101 or Crimestoppers anonymously on 0800 555111.
This is the latest in a spate of bike thefts in the Borders in recent weeks, nine having been stolen in Peebles alone during a three-day spell starting on Thursday, March 16.
One of those was taken from an address in Ballantyne Place, another from Grossland Crescent, two from Edinburgh Road and five – together worth about £6,000 from Crossburn Farm Road.
All nine of those bikes were stolen from locked sheds or garages.
