Rider Profile

Best For	Ideal for beginners or anyone who wants simple, stress-free automatic scooter riding without worrying about gears.
Purpose	Built for short urban commutes, errands, and easy daily transport rather than performance or distance riding.
Rider Fit	Very light and low, with a low seat height and small wheels, making it easy for shorter or less physically strong riders to manage.
Character	A practical, no-nonsense city scooter that prioritizes convenience, fuel efficiency, and manageability over excitement.
Not Ideal For	Not suitable for highway speeds, long-distance touring, carrying a heavy passenger, or any off-road use.

Units

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

Feet:

At 795mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2018 Hero Duet, with a moderate knee angle of around 100 degrees and a slightly forward 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.
