I’ve been riding a bike for exercise for several years, since I had to taper down on my running (which I had done for 45 yrs). I received my pair of Trieyes last March as a bday present, from a non-bike rider. I had never heard of them. But after using them, I found them to be invaluable. I wouldn’t consider riding without them. This past holiday season, I purchased a pair for my brother & another pair for a close friend. I want us all to be safer when we ride & you should too!
