I really like this style of crashbars, they're connected to the grab bar and the floor. It looks and feel secure. I was expecting something lighter but was surprised at their sturdiness and weight. Nice.. First I tried to install the front wheel one bar without taking the wheel off, forgetaboutit!. That tiny little screw that secure both haves of the rear bars really gave me a hard time. It would not fit in the hole. Had I paid more attention I would have seen the second hole next to it that was drilled for that screw. I wonder why two drilled holes. That's the trouble getting old, just can't see without reading glasses. Anyway I like them. Bought them from Scooterpartsco, came nicely packaged.Free shipping can't beat that.
