Rider Profile

Best ForThis bike suits newer to intermediate riders thanks to its modest power output and manageable, predictable delivery.
PurposeIt is best described as a road-biased adventure-styled machine, more suited to touring and commuting than genuine offroad work despite its enduro-inspired looks.
Rider FitA tall-ish seat height combined with a fairly heavy dry weight for its class means shorter or less experienced riders may find low-speed maneuvers and paddling around a bit demanding.
CharacterIt has a relaxed, practical, go-anywhere character with a windscreen and luggage options that lean it towards easy-going touring rather than aggressive performance.
Not Ideal ForIt is not the right choice for riders seeking high-speed thrills, track-day performance, or serious technical offroad capability.

2021 Sinnis Terrain T380 Rider Ergonomics Assessment

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

Feet:

At 820mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with balls of both feet on the 2021 Sinnis Terrain T380, with a cramped knee angle of around 70 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.
