This is our most versatile Moped / Motorbike rack. It has the ability to safely transport Surfboards, Wakeboards, and Longboards, and also Larger SUP Stand Up Paddleboards. It includes 2 sets of arms (one for bigger boards, one for smaller - which have roughly 4" and 6" gaps respectively where the boards sit.) that use a stable quick release system for swapping out or removing. Changing these out takes mere seconds and can be mounted on a scooter, moped, motorcycle, or even quad. Once you have one of these attached to your ride surf checks and finding parking at the beach will be so easy! This mobile system is compatible with a variety of mopeds, motorcycles, and other motorized vehicles using it's ultra-compatible mounting hardware. This rack mounts via versatile clamps that can mount on a variety of areas on the bike. A luggage rack is usually recommended, but because of the rack's versatility, they're compatible with a large variety of bikes. You can securely mount it to the frame, piping, or an existing rack on your vehicle. This rack fits perfectly on the Honda Ruckus, but can easily fit onto a variety of other bikes too. When you just want to go for a ride without the boards, the hooks easily come out, and lock back into place in a flash, using it's patented quick-release system. They're also covered in a high-quality rubber, helping to prevent dings, and include holes in case you want to attach a bungie (sold separately) which keeps the board locked down when driving down winding or bumpee roads. Saving time and gas while riding eco-friendly is in style! Having to find parking when you get to the local beach break or reef is not. Get rock star parking every time! You'll be stoked on this rack, just as much as we are. *It is recommended to mount the arms further apart (closer to the front and back of the vehicle) if you're planning on using boards over 10' for added stability. * The mounting pipes (sleeves) that actually mount up to the moped or luggage rack are 10" in length. Disclaimer Ride responsibly and within your skill level at all times. When transporting a board with the rack installed, be mindful of the additional width of your vehicle or bike. Use extra caution in windy conditions, follow all applicable traffic laws, and always wear a properly fitted helmet—it's your best protection.
