What our Fenix customers say about the BC21R:

Mr DM Nelson “The Fenix BC20R is a  super bright light, simple on and off light. As much light as I could anticipate needing cycling the roads. Works for lighting up tracks, too.”

Mr L Glover  “This is hands down the Greatest light on the market. I have tried many. The Dual Distance Beam actually works with a beam focused out at about 15-20 feet for when you’re on point and another beam centred flawlessly on the front wheel for when you are in the pace line. Remarkably created. This is a very high-quality product just as you would expect from Fenix!!!”
