The Walkthrough

Top curved tube

Top curved tube

Smaller tyres in sizes XS and S have a top tube that lowers down towards the seat tube. And this geometry provides a lower standing height. This feature is suitable for short riders as it allows them to align their bike professionally. Tires in sizes M and L have a straight top tube, as taller riders don't have the same issues with standing height.

 
Suitable for every cyclist

Suitable for every cyclist

Trek releases the Marlin 4 bike in seven sizes to fit riders of different heights. The size of this bike enables you to go at high speeds. The Marlin bikes with small sizes come with shorter brake levers and a narrower steering wheel to help riders cruise in comfort and control.

 
Technology and high value

Technology and high value
