I'm actually not a fan of integrated batteries on e-bikes. Sure, visually they are (usually) an advantage, but the disadvantages outweigh the advantages. Such bikes are heavier and more cumbersome. And now this: I'm surfing down the test trail for the third time and can't get the grin off my face. The E-Zesty weaves nimbly through the terrain. On drop edges, a slight pull on the handlebars is enough to lift the front end. Quick changes of direction are a breeze. Again and again I push off waves and let the bike fly a few metres. Pure agility and riding fun - with an integrated battery! Brave new world?
