Meet the Salamander Cycle: a bicycle that can be converted into a stroller or cart quickly. Just pack your children in, go for a ride, and convert the Salamander into a stroller when you need to go into a store. As you can see in the below video, the conversion process is quite fast:
The Salamander cycle stroller can carry a payload of 100 lbs. It is suitable for riders 5’6″ to 6’6″. You get a 4130 alloy TIG welded frame, adjustable seat and bars, retracting waterproof canopy, folding pedals, and parking brakes. More information is available on Kickstarter.
