Rider Profile

Best ForThis bike suits beginners and new riders, including those on a learner license, thanks to its small engine and low, easy-going power delivery.
PurposeIt's built as a stylish, low-cost cruiser-styled commuter for short urban trips rather than performance riding.
Rider FitThe low seat height and light dry weight make it very manageable for shorter or less experienced riders to handle and balance.
CharacterIt has a relaxed, cruiser-inspired attitude with retro styling, favoring easy cruising over sharp handling or outright speed.
Not Ideal ForThis is not the right bike for highway touring, high-speed riding, or anyone wanting strong acceleration and long-distance comfort.

2021 Keeway Superlight 125 Limited E4 Rider Ergonomics Assessment

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

Feet:

At 730mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2021 Keeway Superlight 125 Limited E4, with a cramped knee angle of around 80 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.
