Rear seat for kids electric bike above battery I have a bicycle as in the picture. Are there any child seats that can be fixed in the rear of this bicycle?
ANy suggestion is appreciated.
In the Netherlands, where most parents cycle with their kids, kids seats are now routinely attached to the seatpost or the part of the frame where the seat post drops into.
The kid will be above the rack but much of the weight will be on the middle of the frame.
There is no contact between the seat and the rack with battery. Many e-bikes are sold with both front and rear kid seats.
I did not find any 'non commercial' pictures so far, but if you google -bobike rear kid seat-  you will find several or many of that brand (other brands are also likely to have them, but I do not know their names, I am not connected to the brand in any way, I just see them used often.)
Do not worry about the weight of the child, many Dutch ride with adults on the rear rack, with no problems. (The racks may not like it, the weight spread over the bike works.) Just keep an eye on how you handle the bike with the weight there.
And do not forget the child when you get on or off when you are used to a diamond frame, see this video fragment.
