Bradford South Neighbourhood Police Officers, together with an Operational Support Team, used specialist thermal cutting equipment to gain entry to the premises yesterday.
Once inside, in addition to the two trials bikes, they found two high value mountain bikes, lawn mowers, strimmers and a range of other power tools. A police spokesman said the value of the goods was estimated to be in the region of £50,000.
Officers want to speak to three males in connection with the discovery of the property, and are now trying to trace all the rightful owners of the goods seized.
Anyone with any information should contact West Yorkshire Police on 101 or via e-mail at firstname.lastname@example.org.
