Easy to use Great product
Worked perfectly to put my cruiser bike on the car rack. Without it was a struggle. If you have a beach cruiser bike it’s worth the money. So easy to use too

Simple Fix for Carrying Step-Through or Cruiser Bikes — Works, But Feels Basic
Simple Fix for Carrying Step-Through or Cruiser Bikes — Works, But Feels Basic The Allen Sports Crossbar Adapter does exactly what it’s supposed to: it adds a temporary top tube to bikes that don’t have one — like step-through, women’s, or full-suspension frames — so they can mount securely on standard hanging-style bike racks. It attaches between the seat post and handlebar stem using spring-loaded hooks, which makes setup fast and tool-free. Once in place, it provides a stable connection for transport. The internal spring holds tension well, and the plastic-coated hooks prevent paint scratches. It fits most adult bikes comfortably, though the bar has a somewhat utilitarian feel — it’s more functional than refined. The spring mechanism can feel stiff at first, and smaller riders may need both hands to stretch it into place. Still, for the price, it’s hard to beat. It solves the fit problem perfectly for beach cruisers and step-through bikes, and it holds up fine for occasional use or road trips. Bottom line: A basic but reliable adapter that makes nontraditional frames rack-compatible. Not fancy, but practical and affordable.

Economy bike cross bar adaptor that works
I have a hitch type bike rack that is not compatible with ladies/commuter bikes. Tough luck for me I didn't realize this fact before ordering my bike rack as they're mostly commuter bikes without the "traditional" triangular frame with crossbars. In order to make my bike rack useful, I ordered this product with some doubt initially about whether this "bare-bone" product would be heavy duty enough to withstand all the vibration using my bike rack on a sports coupe. Per receiving the product I find it be very well-built and works just as described without all the bells-and-whistles like other products on the market that work the same but look just prettier. Functionality is what I was looking for and I needed these adapters at a good price(I had to buy 4 of them for all the step over frames that I have) so I went ahead and ordered these. I feel that this is a great product and it has all the contributes to make it a great product (functionality, durability, ease-of-use). Definitely recommend to anyone looking for a crossbar adapter but want to stay away from the high price, sugar-coated name brand ones. I didn't find application to be of any difficulties and haven't snapped my finger/hand once. Pay attention when using it you won't have to worry about the tension bar design hurting you at all.
