This is for grown ups! Don't put it on the kids bike for them to haul their friends around. It adds virtually no weight to the bike and 55 pounds rating is plenty for a pick nick, quick trip to the store or lightly packed camping trip. Being able to bend the steel mounts to accommodate many bike architectures makes the install easy.
This bike rack is a great value for the money. I mounted it on a schwinn cruiser. The only thing I had to modify was the bolt head that mounts near the rear gear, when in 7nth gear the chain rubbed against the head of the bolt.
A solid rack. The aluminum finish is matte giving it a rather modern look. The rack did tack some finagling to get attached, but after it was on it's been a treat.
