This scrubber is intended for areas without electricity, pressurized water, or personnel and must be affordable, simple to operate, and easy to maintain at trailheads. The current design is essentially a trough of tough bristles through which the rider walks their bike. The motion of the bike provides all the power.
In preliminary tests 75% of the adhered sediment is removed from the tire tread. Comparison with a competing design is discussed and recommendations for installation at trailheads are made. This scrubber is suggested as part of an overall system of reducing invasive species transport by humans.
