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.
