I have a Hydroshot, a larger battery and a 25 litre plastic vessel for water, lives in the boot and means I can clean the bikes off before putting them on the roof, and in this part of the year it means the bikes are cleaned in daylight (almost always dark by the time I get home) dry in the wind of the journey home and are always clean for the next time they are ridden. Takes five minutes to spray a bike down when the mud is fresh from the trails.
