Great little trailer that fits children until the time they're old enough to ride a bike. Sturdy build for neighborhood rides. Wheels are metal, not plastic... Which is the reason I purchased this over other bike trailers in this price range. If you're looking to ride beyond gravel roads, this isn't the trailer for you. Until they build trailers with shocks... the little ones probably souldn't be exposed to that much bouncing. 5/5 Will update if anything changes.
