Currently it is difficult to find a quality tandem, especially if it is electric, that is resistant to all types of terrain and weather conditions and that also offers the best technological features.

At Campmajó we have extensive experience in this sector and we want to take it to the next level. After many years of development we have managed not only to find the best designs for each discipline, but also to have the flexibility to change and adapt them to the tastes and needs of each client.

Our tandems are the best option for great rides in company, be it a pleasant ride, a training or even a competition.


We are a completely independent bicycle manufacturer and our bicycles are 100% manufactured in Catalonia.

We shape the tubes, design and manufacture the machined parts of the bicycles and weld the frames one by one. The fact that we produce bicycles by hand means that we can adapt each bicycle to the customer’s taste, but it also adds value to our product, since each bicycle is unique and has been carefully created, taking care of even the smallest detail.

In addition, the creation process becomes a unique experience for the customer, since he participates in the design of every detail of his bicycle, as well as being able to track and see all the steps we take during the manufacturing process.


One of the most important things to keep in mind when riding a tandem is to make sure you are pedaling in the correct position. Making a custom tandem allows us to make the frame and fork adapted to the body and pedaling style of each pair of riders, considerably improving the experience of the cyclists and ensuring a constant improvement in health and well-being in the long term.

Our artisanal manufacturing method is what allows us to have total flexibility in the design and gives us the possibility to adapt the dimensions of both the frame and the components to the needs of each of our clients.


Bike fitting is a quick and simple option with which, through a form of main measurements, a fairly approximate geometry can be extracted that adapts to the body proportions of each cyclist.

From the measurements of the form, the configuration of the tandem and its geometry are analyzed and adapted to the physical and biomechanical characteristics of each one of the riders. The main goal is to achieve an optimal position on the tandem that maximizes comfort, efficiency and injury prevention.

You can take the measurements yourself from home. Once inside the form, you will see the exact measurements needed.


The possibility to customize the paint and design of your tandem allows you to express your individuality and personality by standing out from the crowd. You can choose from a wide range of colors, patterns, and finishes to create a tandem that reflects your unique style. Whether you prefer bold colors or a more elegant design, paint customization lets you turn your tandem into a unique, personal work of art.

Two colors are included in the price of the frame (one for the whole frame and another for the logos). If you want more colors or a more elaborate design, contact us and explain your idea! Take a look at the catalog and choose the colors that you like the most.


The RAL color range is a range of opaque and standardized colors, coded through a four-digit number. In the following link you can see the entire range of colors, choose the ones you like best and indicate them in the form.


We also offer a wide range of colors with special effects and textures which give endless combinations and possibilities. In this document you will find all the different special effects with their code and characteristics.


In addition to the frame, the components of our tandem bikes can also be tailored to your individual preferences. In the customization form, you can tell us exactly what components you want your bike to have and we will take care of ordering and assembling them.

If you are not sure, on the product page we suggest a pack of standard components that we usually assemble with the best price-quality ratio.


Information about tandem bikes

Although they are becoming more common, two-seater bicycles or tandem bicycles are still quite unknown to most people. Over the years, we’ve received many questions related to tandems that we think can answer any questions you may have and help guide you if you’re still not sure what type of tandem you’re looking for, or if you’re just wondering reporting In case none of the questions solve your doubt, do not hesitate to contact us.

A tandem is a bicycle for two people, they are placed in front of each other. Both participate in its movement through pedaling and each of them has pedals, a seat and a handlebar.

In tandem bicycles, the two cyclists participate in the pedaling movement to transmit force to the wheel of the rudder, generate traction and move forward. Two chains are used, one that connects the chainrings of the two riders and another that transmits the moment of force of the rider to the rear axle of the bike. Instead, the steering, brakes and gear shifting are controlled only by the rider in front. The radere rider only participates by pedaling and accompanying the turns and movement of the tandem with his body.

The force that is transmitted to the wheel is always the sum of the two pedals, therefore, if one of the two does not pedal, nothing happens, simply all the effort will be done by the other.

The size between the axles of the tandems is not fixed. Since they are custom-made tandems and of different types, the length between axles can vary. Even so, so that you can get a rough idea, a road tandem is usually around 1700mm while a mountain one is closer to 1800mm.

Although tandems can be made with all kinds of wheels, the ones we make are always with a 29″ wheel. It is the size that allows cyclists greater comfort, allows them to go faster and is less affected by the irregularities of the terrain.

They are fast! In this type of bicycle, the pedaling effort is divided between two people, so much more power is generated to move forward. In addition, on flats and downhills you can notice even more since the aerodynamics are the same as that of a normal bike.

They are efficient! The weight of a tandem is less than that of two conventional bicycles together, which means that less weight must be moved for the same generated power.

They are ideal for doing sports with another person, a certain level of coordination is needed between the two cyclists and this makes every outing a pleasant adventure as a couple.

No need to stop to wait for the other person. Tandems are ideal for outings between two people with different physical abilities and always going at a good pace! It is not necessary for both people to exert the same effort on the climbs.

The co-pilot has his hands available. In tandems, only the pilot in front controls the handlebars, so the second pilot has his hands free to access the water or the luggage without the need to stop.

They are one of the best cycling activities that can be done with blind people, people with reduced mobility or any other disability that allows them to pedal. Going with a tandem allows them to rediscover sensations such as speed, the physical effort of the climbs, to feel the air again on the flats and descents and to live great experiences with their friends and acquaintances.

They are also a great tool for all those parents who want to introduce their young children to cycling but want to do it in a safe and controlled environment

The design of each of our tandems is the result of many years of trial and error, of constant product improvement in order to offer the best possible experience to our customers. Our intention is to be able to take the tandem sector to the next level and that lovers of two-wheeled bicycles can find the same quality and features that they find when they buy a conventional bicycle. That is why our tandems offer great quality in materials, structure and design, they are designed to be able to mount the latest technology in components.

In addition, we offer the possibility of total customization of every aspect of the tandem; color, geometry and components. We believe that, both with bicycles and tandems, the experience is better when you make it your own, you know that your tandem is unique in the world, it is made to your size and you participated in its design.

In tandems, the part that suffers the most are the wheels, especially the rear wheel. They are wheels that have to support twice the weight of a normal bicycle wheel and, especially in mountain tandems, where the roads are more irregular, the wheels suffer a lot. This is why we recommend always using a double suspension tandem for the mountains, since apart from absorbing the irregularities of the terrain saving work on the rear wheel, it also greatly improves the comfort and experience of the second rider.
