1Up USA Super Duty Single

Start here if you have one heavy e-bike and want room to grow. 100 lb bike capacity in a 37 lb aluminum package, expandable to three bikes with add-ons. Tilt-away for trunk access, carbon-frame-safe, lifetime warranty. The trade-off is no integrated bike lock — you will want to add one separately. I recommend this to solo e-bike riders who want the strongest single-bike platform available and might add a second bike later.
