If you ride a bike, you need to have an Orp Smart Horn on your handlebar, plain and simple. This tiny device combines both a visual and audible alert that is so necessary to protect yourself from the usual obstacles of pedestrians in a polite manner to the unexpected inattentive driver in a more firm way. This ingenious invention has saved me more than once from potentially hazardous situations I’ve encountered in many miles of cycling. It is thoughtfully designed to protect you while you ride. Having used one for the past two years, I would feel uncomfortable not having my Smart Horn at the ready under my thumb!
