Taking the kids out for a walk no longer has to be a boring affair. This TrioBike is a bike with a two-seater stroller attached to the front, allowing you to get your bicycle-based exercise while taking the kids out for some fresh air. You'll appreciate being able to pedal around, and the children will love moving at a speedy clip.
Even better, the stroller can be detached from the bike, allowing you to drop your spawn off at daycare and then enjoy a normal bike ride, rather than being stuck pushing and empty stroller around like some kind of sucker.
