I'm the dad of a bike loving toddler in Portland, Oregon. I ride a Tern GSD and my toddler is 3.5 and right at the limit for the Yepp seat so I'm looking at other options as he's a little squirrely for just cushions. He rides a 14" Guardian bike but we are looking at the next size up. We ride a bit for fun but also just to run errands around town. I'll usually strap his bike to mine and if he feels like riding on some of the paths I'll let him do that till he's had his fill.
