Yepp Mini Bicycle Child Seat Blue

Will this fit on my Rad Runner ebike?

It says that it's suitable for children up to 33 lbs., but is there also a height limit? Our daughter is below 33 lbs, but she's unusually tall.

I know the material is "croc-like" material. Does it get unbearably hot if it sits in the sun for a bit?

On the black one, is the footrest really gray? I saw a picture that it shows it all black and beautiful
