This is a bladder system rinse kit for washing road bikes only. the velocity of the water spray is not suitable for mountain bike. Good for beach goers and outdoors /campers just fill up and load in car to the beach to wash off sand of feet and your pets. Note this system depends heavily on the water velocity in your bathroom preferably your bib tap to store water and spray is weaker as it runs out of water. this is a not an electricity system no need power source like mobi wash from crc.
When viewing pls notify me in advance ,i will fill up with water for testing.
RFS : gotten a kracher instead, if your common bath has no bib tap installed, this is very convenient to use.
