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.
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 lowersthe 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.
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.
