Officers are linking four incidents, one of which was in Sherwood, where a vehicle has been used to gain entry to businesses.
It’s believed a silver transit van was used in all four incidents.
It rammed into a workshop in Mansfield Street, Sherwood at around 7.20pm on Sunday and a cross bike was taken.
Then at around 5.30am the following day, it reversed into three separate units in Park Road in Calverton. A motorhome and motorbikes were taken. One of the bikes is a distinctive specialist race bike.
Three men wearing dark clothing were seen in the van.
