Weeride looks nice. The child can see where they're going.
25 years ago my dad, an engineer, rigged up something similar for my little brother to take him to nursery: a miniature saddle, some steel foot rests and some miniature handlebars, all secured to the top tube. Dad could see the little one in his peripheral vision and toddler could see where he was going.
There's a story that shows how much he loved it. Little'un enjoyed listening to the story of The Snowman which we had on LP. He wasn't allowed to play records but he was able to load a cassette into a tape player so we made him a tape recording. Unfortunately, said LP had a scratch at the pont in the story where the snowman is about to to take off with the little boy in his arms. The line went 'running along through the snower, faster and faster, until they were flying' and then Aled Jones would come in with his little song. The scratch was just after the words 'faster and faster' and it made the needle jump to the beginning of this phrase so that in our version of the story the snowman went faster and fatser, faster and faster, faster and faster, 23 times in all, before the stylus rode through the scratch and the track continued. Little'un just assumed this was how the story was meant to go. It was some while before we discovered this accidental extension to the story.
One morning on the commute as my dad was accelerating along the road, Little'un was heard speaking under his breath repeating the words "faster and faster, faster and faster, faster and faster..."
On his dad's bike he was flying.
