I am a new bicycle commuter, and would like to install something on my bike for my daughter to sit with me when I pick her up from school. So far she has sat sideways on the top tube (which is alright, but not very comfortable), we walk together, or I let her sit on the bike and I walk along side pushing it.
Basically, I want something from the "Multiple Riders on One Bicycle" section on this page:
Many of them look like the second person (even an adult!) is sitting on the rear bike rack, but some use a little extra seat with a backing. I don't know what to search for or where I would find something like that in the US. All of the bike racks I've seen on Amazon are only for cargo and are rated for 15 or 20 lbs. My daughter weights 60 lbs and is only getting bigger
I have a simple Huffy bike I bought at a garage sale (not a mountain bike, it has narrow tires). Thank you for any help or tips you can provide.
