Rider Profile

Best For	This is a purpose-built youth trainer bike intended for young children just learning to ride off-road, not for teens or adults of any skill level.
Purpose	It exists to introduce small children to genuine enduro riding technique on a scaled-down, low-power machine in safe off-road settings.
Rider Fit	Its tiny 665mm seat height, 42kg weight, and low-power 2-speed 50cc engine are sized specifically for a young child's small stature and limited strength.
Character	Playful, forgiving, and confidence-building, mimicking full-size enduro bike looks and feel in a scaled-down, easily manageable package.
Not Ideal For	This bike is completely unsuitable for any adult or teenage rider, road use, or anyone seeking real speed or long-distance travel.

Inseam (optional)

Units

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

Feet:

At 665mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2004 GAS GAS EC Boy 50, with a cramped knee angle of around 55 degrees and an upright 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.
