Freshpark street parks set up anywhere in minutes, fold up for easy moving and storage. Ramps and rails interlock into myriad configurations for the ultimate ride with bike or board. Weatherproof construction ensures that units will not warp or rot like wooden ramps. Four-foot Quarterpipe (shown) has a 10-ft. radius and measures 47 ins. wide and 33 ins. high. Connects side by side or back to back, and can be used with other Freshpark ramps and rails. Wheels detach and unit folds to 20- by 20- by 47-in. triangle for storage.
