I only see 7 But there is another version floating around the internet where someone has Photoshopped a baby in the bucket.
Room for 8.
I want to take my son as a passenger and he is 13. The two problems are that I'm not comfortable myself on the bike yet, and his attention span is so short I'm afraid he would try to do something stupid while on the bike.
But I'm looking forward to the day when he can ride with me.
