BURGLARS smashed their way into a home and stole three bikes worth £8,000.
One of the bikes taken in the raid is a Yeti 4X Special Projects – one of only 100 ever made.
Dave Blanchard, 47, said: "I couldn't believe it when I found out it had been taken.
"I thought, 'surely not'. It took the best part of about ten years to lay my hands on one.
"I got it about 14 months ago after a friend of mine, who is into mountain biking and works in a hotel in France, found it."
The porch of Mr Blanchard's property in Ripley Close, off Greenwood Avenue, north Hull, was smashed during the raid, which happening sometime on Thursday.
Mr Blanchard, who was out when the break-in happened, said the bikes were stored out of view in a spare room.
One of the bikes was found on the grass outside the house, but a Whyte 146 S, Gary Fisher Rig and the Yeti were all stolen.
Mr Blanchard has urged anyone who finds the bikes to contact police.
"It would mean everything to get the bikes back," he said.
"I've spent a long time working hard for them and it hasn't come easy to get them.
"Cycling is my main hobby and that has been taken away with the bikes taken."
Following the burglary, Mr Blanchard turned to Facebook in an effort to get his bikes back.
He said: "I have been putting messages out on social media and I have had a huge response, with people sharing my appeal.
"I don't think the people who have taken them have any idea of the Yeti's rarity.
"There seems to have been quite a few high-end bikes stolen in the Humberside Police area and this seems to be something that is increasing.
"There are another five bikes taken that I know of in the past week."
Anyone with information on any of the bikes' whereabouts should call the police on 101.
