The Tern Vektron Q9 is an evolution of the original Vektron. The folks at Tern have kept an open mind when digesting user feedback from their debut Vektron. The result has been the subtle optimization of an already competent folding electric bike. Not everyone needs the extra power found in the Vektron S10; a bike that is far better suited for San Fransisco and it's many hills.

The Bosch Active Line packs enough punch to keep the Vektron purring right up a steep incline under a full load of cargo. The frame has also been redesigned to have the battery lay more flat under the rack, allowing you to maximize the longer carrier rack.

The last notable upgrade in the model is the Atlas Rack itself. Not only does it have a higher weight capacity, but they've adapted the design from their GSD model, allowing you to stow the Vektron upright to save space.
