I'm looking for the sort of bike seat that attaches to the back pannier rack for 5 - 10 year old kids. I.e. NOT a toddler seat. I had my bike stolen and now replacing all the bits is getting expensive, so would be great to get a second hand one of these if possible, as I think my daughter is now too old for the toddler type seat, but will still want to hop on the back of my bike occasionally.
Or even better, one of those expensive attachments where you can attach a child bike to an adult bike quickly and easily like a "follow me tandem".
Thanks
