1Up USA Heavy Duty Double

The workhorse of the 1Up lineup — 46 lbs, 100 lb total capacity, and the modular system lets you expand with single-bike add-ons. Aluminum construction means no rust and the fold-flat design keeps things tidy when not in use. Carbon-frame-safe and tilt-away round out a feature set that covers most riders. The 50 lb per-bike limit means standard bikes, not heavy e-bikes — for those, look at the Super Duty. Start here, upgrade later if your bikes get heavier.
