Smooth adjustment of the seat
Even as far back as 2000, we 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, which had both the angle and the pedal distance 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
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.
F2F U - Fold to flat ultra
In addition to folding the front part, you can also rotate the rear fork which is designed to fit neatly just below the rear of the frame. The will turn the tricycle into an incredibly small package which you can easily fit into the boot of a small car or into our carry case should you wish to take the trike for example on a plane. And the whole manoeuvre will take you no more than 5 minutes without the need for any tools.
To enable this feature, the rack and mudguards must be removed. Only the Lowrider rack can be folded along with the rear fork. In this case, you will need some basic bike tools and folding the trike may take a little longer.
In 2015, we introduced a new folding mechanism we are really proud of. We wanted to create a folding tricycle that would be adequately stiff and whose folding mechanism would be smooth and easy to operate. The feedback from hundreds of AZUB riders has confirmed that we have definitely accomplished what we had planned.
The folding mechanism has a large ergonomic lever. By large, we really mean large. It is located on the top of the frame so that it would be easily accessible without having to stick your fingers in hard to reach places. This lever makes folding our
The large diameter of the folding mechanism and the long axle placed in maintenance-free sleeve bearings increase the overall stiffness of the entire folding frame.
Foldable or separable
You can choose whether you want a folding tricycle for easy transport or parking, or a separable one. Our folding mechanism is not integrated into the frame, it is a separate part that is screwed into the frame. It
There is only very little need for adjustments, but now and again, you should adjust the clamping force of the mechanism. It’s easy to do and all you need is an Allen key.
Made with precision
The entire folding mechanism is completely made on a CNC machine. Therefore all the parts fit together perfectly and there is no friction. Precision was a requirement we were not prepared to compromise on at all.
Precision with anodising
Since the machines do so well to produce parts with such high precision, it would be a shame to dip them in
Both halves of the folding mechanism are made of 7075 aluminium which has significantly better properties than any other weldable aluminium.
Both halves of the folding mechanism have precisely shaped lugs which lock into each other and increase the torsional stiffness of the whole frame. And the stainless steel lock which holds both halves together is machined to a high precision as well.
The fluidity with which the two halves of the frame move during the actual folding is truly exceptional, courtesy of the sleeve bearings made by the world renowned manufacturer, IGUS. We just love these small grey pieces of durable plastic. Their functionality is absolutely incredible.
It took us hours and hours of thinking and discussions before we thought up and then designed probably the most sophisticated folding handlebars in the world of recumbent tricycles. We would rather not mention the number of prototypes we have made...
Feel the groove
The principle of the concept lies in the grooves that fit together exactly. The ones in the central part of the stem are made of stainless steel and those on the individual halves of the handlebars are made of chromium-molybdenum steel and are painted.
Always the same position
Thanks to the fact that the grooves are large enough, you will always be able to place the handlebars in the same position as they were before folding whilst keeping them symmetrical.
Ye shall not budge
It does not matter at all how much force you will put on the handlebars when getting on or when braking suddenly. The handlebars will not move, not forwards, nor backwards. They will hold their position like a stubborn mule.
The handlebars are made of chromium-molybdenum steel that makes them very stiff and almost impossible to bend.
In order to get the position for the shifters and brake levers ergonomically perfect, we use internal cable
The seat is crucial not only for the comfort when riding a trike, but it will also determine how fast you will be able to corner, whether you and your trike will become true friends and whether you will get the right response from the road that will be running under your wheels. That is why we have devoted so much time to its development as well.
Design is everything
The shape of the tricycle seat is based on the shape of a human back and on the position that the rider adopts. We have spared no expense in getting the bends just right. The seat cushion is long enough to prevent slipping, in the lower back part it copies the proportions of the body, and the curve at the top makes the shoulders and neck bend just right to allow
One size fits all
Our seats compensate for the differences in people’s heights by the mesh cover which can be stretched with straps located at the back. The cover
Setting the tightness
In production, the seat cover is set really tight, though it will loosen a little after several trips. Only then will you experience the feel of its correct side steering, so important during fast cornering. However, the cover should not be loosened too much so that you would slouch, and not too tight since in some places it could uncomfortable for your back. You can adjust the tightness of individual sections with the straps at the back of the seat.
If you are looking for maximum comfort and excellent ventilation, then we highly recommend you get additional padding for your seat, the
For the rear forks of our suspension tricycles with 26" wheels, we have opted to use interchangeable dropouts, common in touring and bikepacking bicycles. This way we can optimize some selected components according to your requirements and take into account the conditions you will be riding in.
The 157 mm wide rear hub and the through axle greatly increase the stiffness of the rear wheel and thus also the riding properties of the tricycle when cornering. The hub was the main reason we have opted for the interchangeable dropouts.
Motors and gearing
We are aware that there are riders who prefer hub gears or hub motors, so we have kept the option to have a standard 135mm wide rear hub fitted as well. Depending on your shifting system or motor, we will choose the correct rear dropouts. And if you decide to change your mind in the future, no worries, it can all be changed, both the rear wheel and the dropouts.
Anodising for precision
We just love it when two things fit perfectly, so we also love CNC machining and aluminium anodising. That goes for the interchangeable dropouts as well. And what is more, we have them anodised in beautiful red so that their uniqueness just shines.
Rohloff OEM dropouts
There is none other professional solution to fit the Rohloff hub gear than the so-called OEM dropouts. They feature an extended left groove for the hub to which the torque bar is attached. So there no Rohloff Torque Arm or Speedbone gets in the way. Rohloff OEM dropouts are fitted as standard on all our bikes.
Short rear fork
The extremely short rear fork is the secret weapon of our tricycles. It not only improves the grip on poor surfaces, but also the riding properties when cornering and the suspension.
Crown in one piece
At the heart of our rear suspension fork concept is the crown, made of one piece of aluminium milled on a CNC machine. It is attached to the trike frame with a large diameter axle, which allows it to be narrow and at the same time to provide sufficient lateral stability.
Not only the crown itself, but also the fork legs made from a D-shaped section ensure the rigidity of our tricycles in the rear. It is a feature greatly admired by many recumbent riders as well as experts. It also played a key role in us getting the Tricycle of the Year 2015 award for our TRIcon 26. Hence, you can enjoy very fast cornering on a trike which will keep its grip perfectly without any flexing whatsoever.
Between the rear fork and the frame there is not only a robust axle but also two large industrial bearings. They ensure smooth operation of the rear fork and long life of the whole assembly. On top of that, you can purchase them anywhere in the world and replace them if necessary.
If your trike is equipped with a standard size rear hub, that is 135 mm (all tricycles with 20" rear wheel and tricycles with hub motors or hub gears in 26" versions), the rear fork will have a Specialized D17 derailleur hanger. This option will make it easier to get a replacement should you need to as it is one of the most commonly used derailleur hangers in the world.
Syntace X-12 through axle
Poor lateral stiffness of rear forks is a problem for most tricycles with a 26" rear wheel, especially those with suspension. This has a negative effect on the riding properties. When cornering, the rider can feel his bottom gliding a bit. This is due not only to the lesser stiffness of the rear wheel (compared to 20" wheel) but also due to the longer rear fork. We have eliminated this weakness by coming up with several design solutions, including a very short rear fork and a wider hub in combination with a through axle. The result has amazed not just us, but also many professionals.
Wider and stiffer
By its very nature, a bicycle is unable to withstand high lateral load. Cyclists usually lean to the sides which means their bikes get affected more or less by vertical force. However, it is different in tricycles. One way to help is to use a wider rear hub to achieve better angle of the spokes. That is why we use 157mm rear hubs that are commonly mounted on downhill bikes whose load is quite extreme indeed.
Unlike a conventional quick release you know from most classic bikes, here the wheel is attached to the fork by a large diameter through axle which is itself screwed into the thread on the right side of the fork. The bearings and the rotating hub are then mounted directly on it. On the left side of the fork you will find a precisely machined cone. Together with the axle, the fork forms a very stiff whole. The German Syntace brand is a tried and tested solution and in our opinion, it is extremely effective. That is why we have chosen it for our tricycles as well.
It is as simple and easy to remove the rear wheel with the trough axle as it is with a quick-release, all you need is an Allen key. And wonder of wonders – it’s hidden inside the axle itself. You will therefore never forget it at home and you will never have to remember what size key you actually need.
Through axles are pretty standard in the world of mountain bikes. Nowadays, any good quality mountain bike has a through axle at least in the front suspension fork and most also have them in the rear as well. Hence, the effectiveness of such a solution has been confirmed by millions of satisfied bikers. We have therefore drawn on this knowledge and experiences. After all, it is a world that develops a bit faster than our recumbent one.
Even though downhill is a minor part of cycling, the parts you need for it are commonly available not only on the Internet but also in specialized stores. So it’s not a problem to get a 157mm wide rear hub with a through axle as a spare part. And if you cannot find it, contact one of our dealers or us directly.
