Recommended for Ages 5 and up (though completely and totally socially acceptable for use by grownups), the FUZE Bike Bubbler operates on three AA batteries, and can be mounted under standard bike seats - in most cases just with a philips screwdriver, though you may need a wrench if the seat itself needs adjusting.
After just 10 minutes for installation, I had this ready to roll here in THE ROCK FATHER's state-of-the-art Toy Testing Facility (our house) and ready to be filled with bubbles.
The quick-release latch allows the Bike Bubbler to be easily removed from the bike for a fill-up or for hand-held play. A little bit of the included bubble solution is touted to "create a continuous bubble stream for up to twenty-five minutes," and that number seems accurate. While our video-documented test was under abnormally windy conditions, the FUZE Bike Bubbler still performed just fine, falling into that "immediate hit" category with my girls.
While we shared a quick look thanks to the immediacy of Instagram, I've got some better quality video to share with you below...
