SeaSucker Hornet 1-Bike Rack

At 3 lbs this is the lightest bike rack in existence — a fork-mount suction cup system for one bike that you can literally carry in a backpack. The 45 lb bike limit covers standard road and mountain bikes. No locks, no e-bike support, and you need to remove your front wheel. The trade-offs are the price of admission for something this portable. I recommend this to travelers and minimalists who want zero permanent vehicle modifications.
