Why Campmajó?
We design and manufacture top-quality tandem bikes entirely in our own workshop in Tarragona, Spain. Every tandem is custom-built to fit your body, your riding style and your adventures. From the steepest mountain trails and climbs to a relaxed Sunday ride through the countryside with or without electric assistance.
We combine precision engineering, premium german aluminium and the best components on the market to create tandems that are smooth, stable and built to last. Unlike mass-produced options, our custom tandem bikes are made to measure, with geometry, paint and setup tailored to you. You’re not just buying a bike, you’re part of a unique creation process that results in a tandem like no other.

Custom components build
Campmajó tandem bikes stand out for their top-quality components, carefully selected and customised for each rider.
Here you’ll find the main brands we work with. On each model’s page, you’ll soon see the standard specs and upgrade options we recommend (work in progress). Meanwhile, this section includes the full list of trusted brands we partner with. Let us know if you have a preference for a specific brand or component — we’ll be happy to adapt your build
Custom paint
We offer a wide range of colors, effects, and finishes so you can give your tandem a unique, personal style. All our bikes are painted in-house at our workshop in Tarragona, ensuring top-quality finishes and complete attention to detail.
Custom geometry
Proper fit is essential on a tandem. We build made-to-measure frames to ensure both riders get optimal comfort, efficiency and control. For shared use cases like rentals or associations, we offer well-balanced geometries based on rider height ranges. In every case, we prioritise the best possible fit.
Once your order is in production, we will ask for your body measurements through this simple form:

The choice of colors can be made after the deposit payment. This is a process where, based on the first design, you can try different options until you select the one you like best. Other necessary information before production will be your body measurements, which you can send us through our body measurements form.
Step 4: manufacturing and delivery
Once your production date arrives, we’ll start crafting your unique tandem with all the agreed details. Unlike most brands, we share the full process with you with regular updates and photos from our workshop so you can follow the creation of your bike.
When it’s ready, you can pick it up in person or we’ll ship it to you anywhere in the world.

Frequently asked questions
Although tandems are becoming more popular, they remain unfamiliar to many. We’ve compiled common questions to help guide you in choosing the right tandem or to answer any doubts you may have. If your question isn’t covered, feel free to contact us anytime.
We offer a wide range of tandem bikes including mountain, road, gravel, touring, city, and track. Except for track, all the models are avaliable in electric-assist version. Whether you want an adventurous MTB tandem or a comfortable city cruiser, we have the perfect option tailored to your riding style and needs.
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.
In conventional tandems both riders must be pedaling at the same time and with the same cadence as the whole drivetrain system is connected. It s possible to make both chains independent but it requires a more complex system that it is only built if asked by the costumer.
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.
Custom tandems ensure the perfect fit for two riders, enhancing comfort, performance, and safety. Unlike off-the-shelf tandems, our bikes are designed from your exact body measurements to guarantee an exceptional riding experience.
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.
Once the manufacturing date of your custom tandem arrives, building it from 0 usually takes between 6 to 10 days. Throughout production, we provide regular updates so you can follow your bike’s progress every step of the way.
We ship worldwide with careful packaging to ensure your tandem arrives safely, no matter where you are.
Our tandem frames have a 5 year warranty against any manufacturing deffect. We also offer ongoing support from our Tarragona workshop, including repairs, maintenance, and technical advice to keep your tandem in perfect condition. Also support with providers from any component purchased with the bike
