Frame Design 

All three bikes are equipped with an aluminum bike frame, which makes the bike lightweight. These frames are also not vulnerable to rust. This makes them quite easy to maintain and a top choice among riders who ride in wet weather conditions.

Aluminum frames are also stiff. But this stiffness provides the bike with stability when climbing and sprinting. However, this stiffness may create some unease and you may experience an overall uncomfortable ride.  

Wheels and Tire

The three bikes have wide tires. With 29”, the Marlin 5 bike tires are the widest. Wider tires come with plenty of advantages. They are not only faster but also provide increased comfort and traction. Such tires also improve handling and cornering.

Wider tires also decrease braking distances and are generally safer. For a mountain bike, it is better bikes are wider so that they can easily roll over rough terrain.

This means that every person will be able to find the right fit for them. In addition to this, the bikes with smaller frame sizes also have short-reach brake levers and narrower handlebars that provide riders with smaller hands better control and increased comfort.

In addition to this, the bike has several features that you will find in high-priced bikes. It has a stylish frame with brake hose routing and internal shift cable that help protect your cable from external elements. Its kickstand and rack mounts make it easy for riders to accessorize it.
