Description The Project Flock Bike Rack Mount allows you to fit your biomotion Flock Light to your bike’s rear carrier rack. Because the Flock Light is a popular solution for the commuter cyclist, Project Flock have made a rack mount. While your Flock Light won’t light up as much of your legs, it’s still a bright rear light! And of course it will light up your pannier bags and their reflectors if they have them (like Ortlieb’s do) Project Flock Bike Rack Mount Features & Specs Compatible with both 50mm bolt spacing & 80mm Supplied with nuts & bolts for installation Not keen on the idea of fitting your light to your rack? You will also be able to fit it to your saddle rail using this mount. Meaning it will illuminate from down on to your legs & your rear rack.
