Italian bike and component brand 3T is appealing for help after its factory building was broken into earlier this week.
The break-in saw display and demo bikes, and a unique frame painted by the late Dario Pegoretti, stolen from the building in Italy.
A statement on the brand’s website said: “The thieves drilled a hole through a one metre thick wall to enter our warehouse.
“After that they moved quickly to break the warehouse door, cut the fence surrounding our office and move more than 20 bikes into their van.
“The police arrived within ten minutes, but they already had left.
“Saddest of all, one of the stolen bikes is an Exploro painted by our dear friend Dario Pegoretti, who died a few months ago.
“He painted this bike as a gift to us for launching our first bike ever.
“Everyone at 3T is in shock that this happened, and the level of professionalism of the thieves.
“If any of you see any of our bikes offered on the internet, at stores or in any other way, and it looks suspicious, please let us know.
“And keep a particularly eye on the Pegoretti bike. Your help is greatly appreciated!”
