Thule Helium Platform XT 2

The Helium name tells the story — at 43 lbs with aluminum construction, this is built for people who remove their rack frequently. Tilt-away, fold-flat, integrated locks, carbon-frame-safe. The trade-off is the 37.5 lb per-bike limit, which rules out e-bikes and heavier mountain bikes. I recommend this to road cyclists and lighter-bike riders who want every convenience feature in the lightest possible package. Start here, upgrade later if your bikes get heavier.
