CYCLING PLUS - JAN 2018 ISSUE
The Kinesis 4S frameset has a positive ride feel that’s lively but with great solidity, making it a strong contender for anyone in need of a Swiss Army knife of a training bike that doesn’t lack performance.

Cycling Weekly
For a bike to be ridden through the vagaries of British weather, the 4S Disc frame and its build kit make a lot of sense. There’s enough clearance to use wider tyres and still fit mudguards.

Bikes Etc
The aim of the 4S is to provide a bike that will be worthy of use throughout the four seasons and it has undeniably succeeded.
The frame feels responsive, agile, punchy, when it needs to be, but these qualities are offset with equal amounts of comfort - enhancing characteristics and that is a difficult marriage to make.
A winter bike must be comfortable and hard wearing, but it mustn't let you forget you're a road cyclist, and the Kinesis 4S treads this line admirably.
London Cyclist

it’s fair to say it not only looks the part with its sleek finish and super neat cable routing, it’s also really responsive, quick off the mark (great for interval training) and stable at speed.
