Rider Profile

Best For	Suitable for both newer riders and experienced commuters, thanks to instant, clutchless electric power delivery that removes gear-shifting complexity.
Purpose	Best suited as an urban and suburban commuter that also rewards spirited backroad riding with strong low-end torque.
Rider Fit	A manageable mid-weight naked bike with a moderate seat height, making it accessible to a wide range of rider statures.
Character	Quiet, torquey, and instantly responsive, offering a modern, minimalist riding experience without engine vibration or noise.
Not Ideal For	Not the right choice for long-distance touring riders or off-road enthusiasts due to its limited range and street-oriented setup.

Units

Calculated in your browser only - your height/inseam are never sent to our servers.

Feet:

At 807mm, a rider of 68.9" with a 31" (estimated) inseam will reach the ground with both feet flat on the 2021 Zero S, with a relaxed knee angle of around 120 degrees and a forward-leaning riding position.

Data quality: measured. Assumes about 30mm of suspension sag once seated (a typical street-bike rule of thumb - stiffer or softer suspension will vary). This is an approximation from category-typical geometry and generic body proportions, not a measurement of this specific bike or you - sit on it before you buy.
