A unique alternative to e-bikes. The Dog Powered Trike. As it says on the website:
-it gives the rider precision steering control, with great braking
-the ability to help by pedalling,
-can handle up to 4 dogs,
-and the thrill of dog mushing/pulling!
Since e-bikes never sell in Denmark and Scandinavia unless you're disabled or elderly, [the rest of us have normal leg muscles :-)] this is at least a cool twist on walking the dog.
Fascinating and not a little weird.
