Product Reviews

Of all the e-folders featured here, the Vektron Q9 is the one that brings the most full-size e-bike qualities to the table. It is the only one with a mid-drive, in this case courtesy of Bosch, making it the most powerful e-folder here.

Ebiketips

While it weighs less than 50 pounds and folds up to roughly the size of a skinny end table in seconds, the Tern Vektron Q9 is versatile enough to carry riders up to 6 feet 3 inches with everything you need to get to work.

Elektrobike
