Cateye’s 5.6-ounce HL-EL625RC Nano Shot feels incredibly light when mounted on your helmet or handlebars, and casts a strong 600-lumen beam that extends way out in front of your mountain bike. This one-piece unit from Japan conveniently charges from any device with a USB plug. It’s not the brightest in the bunch, and takes longer to charge than the other selections (an eight-hour powerup), but its $120 price tag delivers the best value.
