Adjustable seat, appropriate for riders around 2 to 8. Two saddles bags, a large mesh pocket behind the seat, cup holders and safety flag. We loved the WeeHoo compared to some other bike trailers we’ve owned because the pedals help them feel more involved and really contribute. Since it’s narrower than most it’s also more maneuverable and easier to pull, especially on windier days. Two quick-release clips make it easy to pack into most car trunks, and it only takes about 30 seconds to set up once you get to the bike trail. We paid $400 at REI when we bought it, and it’s been worth every penny. As you can see in the photo, our 10yo is really pushing its limits, but younger or smaller kids and toddlers will have a blast for years since the seat slides forwards and backwards from the pedals with an adjusting hand-screw.
