Rider Profile

Best ForThis is an entry-level, low-power electric scooter suitable for complete beginners or those without a motorcycle license in many regions.
PurposeDesigned purely for short, slow urban commutes and errands rather than any kind of performance riding.
Rider FitIts light weight and low seat height make it very easy to manage for riders of small stature or limited strength.
CharacterA quiet, simple, no-frills electric runabout with modest torque and a top speed capped well below highway limits.
Not Ideal ForThis scooter is not suitable for highway travel, touring, passenger carrying, or anyone seeking speed or excitement.

2012 Giantco e-Dolphin I Rider Ergonomics Assessment

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

Feet:

At 780mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2012 Giantco e-Dolphin I, with a moderate knee angle of around 105 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.
