If you are into riding classic or old school style bikes with solo seat, you probably have adopted (and adapted) a springs seat type suspension system. Not necessarily the most comfortable ride… Obsessed with the idea of improving his ride and after making a total of 356 seats with hinge in the front and springs in the rear, Ryan Devine got the light. One day, while removing with a tweezer a splinter from his finger, his attention turned to these tweezers and realized that the design just might work for a fully suspended, level riding suspension seat! After building the first “Tweezer Action” suspension seat and riding it proved to be a success. With his system, Ryan claims that he can ride comfortably 1,000+ miles a day!
How does it work? the lower spring holds the seat from the middle and allows the whole seat, front to rear, to ride fully suspended. The upper and lower spring resemble a pair of tweezers. The seat suspension can be mounted several and set up to fit just about any application. A universal quick disconnect handles removing seat assembly when needed. Note, spring assembly mounts on frame, at the rear of tank. (on pictures, leather was used to cover frame and electrical, held in by dash and by two retainers.)
