It's the wheels that matter. The inductance loop creates a field in whatever is near - if there's enough surface area of metal close enough to the loop, it changes the inductance in the loop and a detector triggers. So it generally needs to be metal - the rim of a bike tire - and it needs to be right over the loop.
