Bike Rack for your longboard. Ride to the beach with your surfboard. Easily attaches to the seat post mount of your bicycle. Frame mounting with wide bar spread makes these racks far more stable than other racks on the market. Because of their strength we can recommend them for use with SUPs (Stand Up Paddle Boards) that weigh up to 11kg. All aluminum and stainless construction for coastal environments. Hardware is highly adaptable allowing the racks to work with just about any bike, and just about any board from short to long to SUP. Bars click in for use, or click out when they aren’t needed, with a simple push of a button. Comes with printed installation instructions.
