The Urban Assault Bungee is a 3 ply latex bungee that is anchored at one end, and has a ride handle on the other. A rider and a friend stretch out the bungee, then release it. Once released the Bungee will recoil launching a rider in any direction up to 20 mph. You won't ever need to build another roll-in ramp again.
The Urban Assault is ideal for riding in urban settings where space is limited and massive speeds aren’t warranted or for lighter riders generally up to 120lbs.
Remember, you can control the speed depending on how far you stretch it.
