Rider Profile

Best ForNote: the specifications provided are for a Zontes ZT125-G1 Scrambler, not the named Zero Engineering Type 5, so this profile reflects that small-displacement commuter bike rather than the custom Zero Engineering machine; it is best suited to beginners an
PurposeThis is a lightweight, low-powered commuter-scrambler intended for short urban trips and light leisure riding rather than performance or serious off-road use.
Rider FitAt 160 kg with a 770 mm seat height, it is easy to handle for riders of most heights and physical strength, including smaller or less experienced riders.
CharacterIt has a friendly, approachable, low-stress character with modest power delivery, forgiving handling, and simple non-adjustable suspension suited to relaxed riding.
Not Ideal ForIt is not for riders seeking high-speed touring, aggressive cornering performance, serious off-road capability, or comfortable two-up long-distance travel.

2023 Zero Engineering Type 5 Rider Ergonomics Assessment

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

Feet:

At 770mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2023 Zero Engineering Type 5, with a cramped knee angle of around 65 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.
