Rock Machine Rokk 30 Easy Entry 28 bike, black
Rock Machine Rokk 30 Easy Entry 28 bike
The Rokk 30 Easy Entry 28 bike is equipped with a Shimano transmission system with 3 chainrings and 7 sprockets, which offers the right gear for every situation and ensures long-term reliable operation with minimal maintenance. Reliable and sufficiently effective V-brakes guarantee safe riding. For maximum comfort and an excellent overview of what is happening around you, the bike is designed with an ergonomic riding position. The suspension fork helps reduce fatigue when riding on uneven surfaces, and the ergonomic handlebars, inspired by MTB models, are shortened for a more comfortable hand position.Basic model at an affordable price for a casual user looking for an alternative means of transport to get from place A to place B.
Aluminium frame
Lighter, relatively durable and stiff material that is affordable. The most widespread material for the production of bicycle frames.
V-brakes
The most widespread type of brakes for affordable bikes and children's bikes. Better transfer of force to the brake arms. Not very well protected against external forces. Loss of braking effect in mud or wet conditions.
Coil fork
Provides adequate comfort and is usually installed on bicycles for recreational and less demanding riding. The disadvantage is its relatively heavy weight.
28” wheels
Often marked as 700c. They usually have a narrower profile, lower weight and high stiffness. They are the standard, especially for road (CX, gravel), trekking, city and cross-country bikes.

All bicycles at the MTBIKER shop are new, not-ridden, from an official distributor and with a full warranty. Several brands even offer a lifetime warranty on the frame after registration. We perform all warranty services in MTBIKER stores after personal delivery or after sending the bike (or its part) by courier.
- The bicycle is taken out of the manufacturer's box
- The bicycle is assembled, inspected and adjusted (front and rear derailleur, shock, fork, wheels,...)
- The bicycle is carefully packaged back into a box and shipped
- If you order a bike for in-person pick-up or home delivery, the bike will be waiting for you assembled and checked
- If you order a bicycle via courier to your home address, the following must be done at home:
- Take the bike out of the box and carefully remove safety material and foils
- Mount handlebar to stem (1 minute, 4 or 5 mm hex hey is needed).
- Mount front wheel to fork (1 minute, without the need of any tools if the bike has a quick release).
- Loosen the screws in the headset, straighten the stem with the front wheel, tighten the upper screw on the fork and then tighten the headset (2 minutes, 4 or 5 mm hex key is needed).
- Mount the pedals to the cranks while lubricating the thread and carefully mounting it the right way (1 minute, 8 mm hex key or 15 mm wrench).
- Mount seat post to frame (10 seconds, without needing any tools if the frame has a quick link).
- Inflate the tires or fork and shock to desired pressure (2 minutes, pump needed).
- Check the tightening of hex keys and quick-releases (2 minutes, 4 and 5 mm hex key is needed).
- Go for a test drive! Handle your bicycle carefully until you get used to it. If the bike has disc brakes, their performance will be limited from now on - they will gain their full power after 4-5 strong brakes at higher speed.
