Hall said all the frame numbers of the stolen bikes have been logged and that any IBDs being offered bikes for sale in the next few days should be wary.
The stolen bikes include Specialized Epics, Enduro, Stumpjumpers, Rockhoppers and Hardrocks, as well as many Trek hard-tails.
BMX bikes stolen include models from Hoffman, Nirve, Felt, and Mongoose.
A police rad on a house in Manchester today recovered five of the bikes, but the rest remain missing.
