A closer look at the model

The bike in detail.

Marlin 4 is an extremely versatile bike. Perfect for trails, it is also ideal for everyday travel and weekend adventures. It is equipped with a stable frame with cushioned fork able to smooth the roughness of the rugged paths, a Shimano ESPA gearbox at 8 speed and coupling points for luggage carriers and stands. Whether you're going to class, work or start a trail, Marlin 4 combines the comfort and safety of a bike to commute with the strength of a real mountain bike.

Will my bike have a curved horizontal tube? - The smaller frames have a horizontal tube that curved approaching the saddle tube. This design offers a lower standover height, which is great for less-high cyclists because it allows them to get on the saddle more easily. The larger frames are equipped with a straight horizontal tube, since the taller riders have longer legs and usually do not have the same problems related to the height of the standover.

Questions before you ride?

How do I check availability in my size?
The size table distinguishes in-stock items, online orders and sold-out items. For sizes available on request, use the contacts in that row to confirm availability and lead times with our team. Only variants available for online purchase can be added to your basket.
Can I test a bike before deciding?
The Doctorbike Bike Test is available by category, rather than for every individual model. Our team will confirm the category, size and test availability with you.
Can I get help with size and riding position?
Yes. Talk to our team and explore bike fitting with Velosystem® technology, with dedicated measurements and adjustments.
Who should I contact for servicing?
Contact our certified workshop in Magenta. Arrange the work and an appointment with us: our service continues after purchase.
