The FAT mania can be seen everywhere in the world of bicycles. Not only bikes are FAT, but also carriers, roof racks, mudguards, travel cases and many other sometimes useful or sometimes completely weird things. In some cases you almost do not believe it is possible. Imagine a fat folding electric bike. Why anyone would need it? But, yep, it exists.

The AZUB FAT trike story
We loved the look and idea of the first real fat trike when it appeared back at the end of 2013, but we didn`t really plan to introduce one as we had had way enough orders to deal with. Then our friend Honza Ždánský came with an idea of crossing the frozen Siberian Baikal lake in March 2015. It did not take too much time to realize it would be great to try it on a FAT trike. So we built one. Not only a working prototype, but also beautiful to our eyes. With red frame, red anodized rims, with Tubus carrier etc. Honza unfortunately did not manage to cross the lake as the weather was too warm, and there was too much of open water and even an earthquake, but the fat AZUB trike was born, and couple of months later we decided to start the production.

AZUB FAT trike
We built it based on our non-suspended either separable or folding T-Tris recumbent trike and made the frame wide enough in the rear to accommodate a 26x4,8" rear tire. We added higher handlebars and chosen components - not only functional but also great looking. The AZUB FAT trike has no suspension and therefore belongs among representatives of the classical fat bikes. As well as other AZUB trikes, it has a very good weight distribution with the rider sitting as close to the rear wheel as possible, which significantly improves the grip of the rear wheel in difficult terrain. Also the seat bottom height is low, which decreases the ground clearance a bit but improves the stability. 

Basically, all AZUB bikes and trikes are custom built, and the FAT trike is no exception. You can order it with different colors, drive train components including the Rohloff hub or the the amazing 18 speed Pinion drive (for the first time in standard AZUB price list), and many accessories. However, the red rims and Schwalbe Jumbo Jim tires will always be the same. We just love them and we are pretty sure so do you.

Note: The photos and video is showing a prototype of the FAT trike.

Features of the Azub FAT include:

IPS system of AZUB recumbent trikes IPS - Ideal Position System
This system has made AZUB famous since the brand’s foundation in 2000. It allows riders to find the right position on their AZUB recumbent through a wide range of adjustable seat positions, through the possibility of adjustment their under-seat or upper-seat steering and last but not least, through the possibility of setting the ideal frame length.

sliding seat bracket as a standard on all AZUB recumbents and trikes

Sliding seat bracket
Our new system of saddle
sliding immediately on a frame tube, which is used in all our bikes and trikes represents a further development of our IPS and we are really excited about it. It is really accurate in operation, fast and allows you to adjust your seating position with millimeter accuracy.

In order to facilitate handling, we have placed a guide rail on the frame, which prevents the sleeve from spinning and the angular offset of the seat to the seating plane and pedaling position. The entire bracket is then controlled by two quick releases. The upper one releases the seat, the lower one allows for moving the seat on the frame.

The bracket is made of heavy-duty plastic reinforced with glass fiber and we have been testing it in full operation for many months. The technology we use within its production also guarantees that the frame will remain free of major scratches even in frequent shifting.

> F2F - folding trike 
The TRIcon is a folding trike with a folding hinge allowing you to fold the trike into a flat package within about a minute, or even less. The hinge we use is solid, easy to use and quick in operation. 

The trike can be folded in half for transport in a car trunk. You can get a much smaller package by dismounting the rear wheel and folding the rear fork using just one quick release.

If you need to have the trike folded as much as possible, you can also quickly remove the front wheels and you get an amazingly small item. 

For serious travels with your TRIcon trike, we offer a transport bag. This soft suitcase can also be used together with a special trailer for carrying baggage during your journeys. 

New folding hinge (and a separable frame)
After three years of building folding trikes we decided to improve the folding mechanism. We have redesigned it completely to make it more user friendly, durable, and to offer more precise operation, easy maintenance, and last but not least, the possibility to replace the whole hinge easily in case of need.

The hinge itself is not an inseparable part of the frame, it is a single unit which is inserted between the front and rear part of the frame.

This offers many advantages.

It is possible to manufacture the folding hinge from 7075 aluminium alloy, which is stronger than any weldable material.

It is possible to use hard anodizing instead of powder coating. All parts can be manufactured with extreme precision. This surface treatment is well know for improving mechanical resistance, but we went a step further and decided to have all parts teflon (PTFE) hardcoat anodized. This method, usually used in armament industry, offers ultimate surface protection and also minimizes friction, which is exactly what we needed.

Thanks to presisely matching jags and sags, the frame resists torsional strain much better.

Larger diameter, longer hinge axle, which rests in maintenance free sliding bearings, improves the overal strength.

The hinge has an ergonomic XXL quick release lever which is positioned on the upper side of the frame. This makes both folding and unfolding extremely easy and smooth.

The hinge is easily adjustable with an Allen key.

And it is, of course, possible to remove the hinge and screw both parts of the trike frame together for hard core (ab)use.

Please note that the folding hinge has been optional from beginning of 2015.

ergonomic position of controlers on AZUB recumbents

The ergonomic positions of shifting systems and brakes

Other manufacturers’ recumbents with under-seat steering are equipped with “bar end” or “grip” shifting systems. From our viewpoint, none of them is satisfactory. Especially in combination with non-ergonomic position of brakes as they don’t allow for a simultaneous use of shifting and braking functions. Furthermore, the grip shifts are being positioned on the little-finger side of a rider’s palm. Riders often complain about having difficulties turning the shifts and not having enough stopping power. It becomes almost “mission impossible” to shift when it is raining.

That is also why we focus so much on the ergonomics of our bikes’ components and on their safe and enjoyable usage. When you are riding AZUB recumbent, your brakes are readily available and your gears where you expect them to be. Also, you can choose for a wide array of components that you’ve been used to on classical MTBs or trekking bikes.

At the end the Dura Ace bar end shifters are a standard in recumbent world and many riders like them and require them. That is why we have them in the offer as well.


high seat adapter for recumbent trikes - seat riser  High seat adapter and adaptive accessories for disabled riders
Seat height of the TRIcon is 31cm/12,5", but we also offer High seat adapter which increases the height by 6cm/2". It makes getting on and off the trike much easier. However, you should be aware of the fact that higher seat decreases the level of stability when going fast through curves. 

We also offer adaptations for disabled riders, such as brake levers and shifters that can be operated by one hand, or our famous push brakes allowing braking to people who cannot operate standard brake levers.  

For those who have hard time to operate even shifters, we offer Di2 electronic shifting from Shimano as a solution.

Wide range of options and accessories
We offer an unbelivable range of options and accessories. You can choose from basic Shimano Alivio components through Deore, or XT till Rohloff 14 speed hub. Also SRAM Dual Drive gearing or Alfine gear hubs are available. Not talking about a possibility of electronic shifting or even 18 speed Pinion hubs we build upon special request. Almost everything is possible. Then you can choose from endless list of brake options, cranks, forks, shocks, tyres etc. Also BionX electric motors are available. Not talking about all the accessories we offer you and which can be assembled on your bike. If you need help, please, read our Buyer`s guide or contact AZUB dealer or directly us.

production of recumbents in The Czech Republic Production in Czech
At AZUB, we are very proud that an overwhelming majority of production process and assembly of our recumbents take place in the Czech Republic. The rest is done in the neighbouring Slovakia. From the first sketch, continuing with bending of tubes, welding until the last screw screwed up, we produce everything in the heart of Europe!

The production process of all parts of our frames is computerized using the CNC technology, be it for welding of parts for the seat fixation or bending of the frame tube itself. You can appreciate human craftsmanship when looking at the visual aspect of welding on AZUB bikes. Their quality and aesthetics are incomparably better than the ones of frames produced in Taiwan or in mainland China.

The assembly of our recumbents takes place at the AZUB headquarters. It is undertaken by experienced mechanics who’ve been building up recumbents for almost a decade. Each bike  is carefully set up according to the height and weight of its future owner and tested prior to shipping. Therefore, when ordering an AZUB bike you can be sure that the bike you’re getting is perfect.
