Rider Profile

Best ForNote: the listed wheel sizes, spoked wheels and dual rear shocks suggest this Century variant leans toward a classic scrambler-style small-capacity bike rather than a pure sport machine despite the 'Sport' category label, and it suits beginners or riders
PurposeBuilt as a light, low-displacement machine intended for learner-friendly street use, short commutes, and casual weekend rides rather than outright performance.
Rider FitThe 790mm seat height and 135kg dry weight make it very approachable for shorter or less physically strong riders to handle at a stop and in low-speed maneuvers.
CharacterIt has a simple, honest, retro-tinged personality with modest power delivery that rewards smooth, relaxed riding rather than aggressive throttle use.
Not Ideal ForThis is not the right bike for riders wanting high-speed touring, motorway overtaking confidence, or serious off-road capability.

2025 Rieju Century Rider Ergonomics Assessment

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

Feet:

At 790mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2025 Rieju Century, with a cramped knee angle of around 70 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.
