How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built for punchy, silent urban and back-road riding where instant torque and light weight make for playful, quick acceleration off the line.
- Built for
- A quiet, torquey electric sportbike that trades a traditional engine note and long range for instant, linear acceleration and low maintenance.
- Not ideal for
- Not ideal for riders planning long highway touring days or off-road adventures, given the limited range and street-focused chassis.
