Rider Profile

Best ForBest suited to riders with some trials or technical off-road experience, given its specialized low-speed, obstacle-focused nature.
PurposeBuilt purely for technical trials-style enduro riding over rough, tight terrain rather than any road use.
Rider FitIts light, slim build and tall ground clearance favor agile, physically active riders who stand and shift weight frequently.
CharacterA nimble, momentum-light trials-enduro machine that rewards precision and control over outright speed.
Not Ideal ForNot suitable for riders wanting highway speeds, long-distance comfort, or passenger carrying capability.

2016 FX Bikes FX5 Steel Rider Ergonomics Assessment

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

Feet:

At 812mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2016 FX Bikes FX5 Steel, with a cramped knee angle of around 70 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.
