2 types of steering

You can choose from two different styles of steering. It is either the ASS – above seat steering (also called over seat steering) or the USS – under seat.

Asymetrical rear fork

The design of our asymmetric rear fork we presented at the SPEZI 2007 astonished not only recumbent bike riders but also professionals. It is not a gadget for a mere showing off! You can experience the functionality of its original shape and of its unique fit into AZUB frames on the Mini, SIX and MAX models.

Pogo effect

The radius of the placement of this asymmetric rear fork provides plenty of space for the movable chain pulley which eliminates the so-called pogo effect (lateral swinging of a recumbent bike when pedalling rhythmically or using force) and makes the chain run much smoother. The equilibrium and qualities of the whole construction are ensured by the radius of the rear shock placement in the opposite direction.

Stiffness and extremely light weight

The whole rear fork is made of specially designed thin-wall tubes AL 7020. This gives it two essential qualities that you are looking for: stiffness and extremely light weight. The interchangeable rear derailleur hanger of the gear system has become a standard feature on all AZUB models.

IPS - Ideal Position System

We firmly believe that a bike should adapt to the rider and not the other way round. Therefore, when Aleš designed his first recumbent bike back in 2000, he already tried to make it as adjustable as possible. And today, all our bikes and trikes are like that too. Adjustable features greatly help when learning to ride recumbent. Because when you buy your first recumbent bike, you have no idea if you will prefer sitting more upright or more reclined, you will only be able to decide after many hundreds of miles. With our bikes, adjusting your seating position couldn’t be easier.

Millimetre by millimetre

Two struts with special threads allow you to tilt your seat exactly to the position you want. No matter if you need it set extremely upright or truly reclined. The stability of the whole setup is ensured by two ergonomic locknuts with rubber inserts, and the laser etched markings on each strut make the adjustment very easy.

Smooth adjustment of distance from pedals

The distance between the pedals and the seat can be set not only with the so-called boom, which we usually do according to your height when the bike is built, but also by moving the seat itself. Therefore, when there are two of you taking turns with the bike or when you want to get your friend to try the amazing feeling of reclined riding, you can adjust the seating position on the bike very easily.

Fantastic range of positions for handlebars

The handlebars can be set to an extremely wide range of positions. The way they are set in the stem is the same like in a classic bike. In recumbents with ASS, it is also possible to set the tilt of the stem and the distance of the handlebars from the body, in short, to create the most comfortable seating ever.

Sliding sleeve for the seat

The sliding sleeve is made of glass fibre reinforced plastic. You can set your seat with millimetre precision and it will only take a few seconds as everything is controlled by two red anodized quick releases. Easy, fast, functional.

Movable idler

We’ve eliminated the “pogo effect” by placing a chain pulley on the Top Line models. What is more, it is positioned on an axis made of high quality stainless steel, which allows the chain to swing smoothly from the left to the right according to the set gear. This technical solution improves the chain’s lifetime and lower the resistance that occurs when the axis is in a fixed position.

Smooth adjustment of the seat

Ever since we started back in 2000, we have always thought that a bike should adapt to the rider and not the other way round. That’s why we used an adjustable seat for our first bike, in which both the angle and the pedal distance were adjustable. With each further development stage, we introduced a more accurate adjustment, until 2013, when we reached a stage of adjusting without positions. This concept is based on a sliding sleeve, which we produce in a straight version for our tricycles and some bicycles, as well as in a curved version for recumbents.

Reinforced with glass fibre

The sleeve is made of durable, glass fibre reinforced plastic which we opted for in order to prevent scratching of the paint even during frequent use.

Perfect fit

It is extremely important for the seat to be secure whilst riding, which is why there are two small hard-anodised aluminium parts attached to the lower part of the seat. They fit onto a three-part stainless steel insert that is fitted within the sleeve itself. When you tighten the quick release, everything slots together nice and tight.

Speed and simplicity

Adjusting the seat is very easy. The upper quick release is used to secure the seat and when you release the lower one, the grip around the frame loosens and the seat can be moved. If you are a heavy rider, the lower quick release must be tightened really firmly.

Super-oversized main frame tube

AZUB frames are recognisable by their central frame tube to which all the major elements are fixed, be it the head tube with the front fork, the seat, the rear fork bracket or the luggage racks. This solution not only gives our bikes maximal stiffness and solidity, hence providing stable riding performance, but also an important carriage capacity in the form of its back carrier. You will especially appreciate our technical solution when fully loaded with several bags behind you, as their weight will not influence the riding performance of your recumbent at all.
