What is a prototype?

A prototype is a preliminary model of something. Projects that offer physical products need to show backers documentation of a working prototype. This gallery features photos, videos, and other visual documentation that will give backers a sense of what’s been accomplished so far and what’s left to do. Though the development process can vary for each project, these are the stages we typically see:

Proof of Concept

Explorations that test ideas and functionality.

Functional Prototype

Demonstrates the functionality of the final product, but looks different.

Appearance Prototype

Looks like the final product, but is not functional.

Design Prototype

Appearance and function match the final product, but is made with different manufacturing methods.

Production Prototype

Appearance, function, and manufacturing methods match the final product.

SideBuddy is the cargo trailer that provides new solutions to bicycle transportation needs. It attaches to the side of the bike to allow easy viewing of children or pets riding along + is convertible into a Stroller.

Quick Facts:

  • Created in Sweden - a leading country in bicycle transportation
  • Easily detaches from the bike in under a minute
  • Eco-friendly by supporting sustainable transportation 
  • Carries up to 120 kg
  • Only weighs 20 kg
  • Collapsible 50cm


 Sidebuddy can be disconected and connected to the bike in under 2 minutes. Due to a patent pending application we can not disclose the technical details regarding the connectors.



SideBuddy is more than just a cargo trailer for bicycles - it's a multifunctional tool that easily detaches and transforms into different products.




  Today the biggest Cities in the World, have air pollution, we propose a new transportation solution to reduce the use of Cars and make you stay healthy.

 We propose an alternative way to move in urban areas. Making it easy and convenient.



When we were filming promotional videos for the SideBuddy one thing was clear: kids love this thing! Those aren't fake smiles in the photos... we literally couldn't pry them out of the cargo trailer. When it was time to end filming we would often hear, "one more time!"


Kids have a better experience while moving because the transparent body will give them an extraordinary sensation while having full view of their surroundings.


Glow in the night with the super cool LED light feature! Available in 12 different colors (only with transparent body).



  Possible to select different patterns for the body parts. More than 50  different available. This service will be provide by our partner Hydrodip.


 Choose from 10 different colors and customize the look of the Dampers and mudguards (above rear wheels). (Colors: dark blue, light blue, dark green, light green, transparent/white, red, orange, yellow, pink, violet, white, black)




Steering and making turns is very smooth. The small front wheel follows the motion of the bicycle and glides with ease - there is no heavy friction weighing the bike down.

180° TURN ✓. Easy

 90° TURN ✓ very easy


We added sliding doors located on the left and right side to allow easy access when loading children or cargo.



The SideBuddy can carry all type of things, boards. You name it, is up to you. With a max load of 120 kg.





Most other bicycle cargo trailers come in one size - but not the SideBuddy! 

Available in two different positions: extended and collapsed. It collapses 50 cm (19.6 in) and can be used as a stroller to carry kids or shopping bags.

 The walking handle is under development by our engineers and producers.


The SideBuddy can be joined to the rear of the bike in the case of narrow bike lanes. A connector located at the front of the cargo trailer attaches to the back wheels of most standard bicycles.


The product is designed around safety and ergonomics, selecting the right components for he good function and the safe ride with your passenger,pet or cargo.

There are multiple additions to the cargo trailer to ensure you have a safe ride.     



  • The product and each of its main components have been developed by or mechanical engineers and designers to ensure the product is ready for the production stage.
    Made of extra light materials:
  • ABS Plastic Structure
  • Fiber Glass Body
  • Aluminium Composite Flooring
  • Carbon Steel Rear Chassis
  • Stainless Steel Front Chassis
  • Magnesium Alloy Wheels
  • Dual Brake Disk System







Note: We will contact buyers after the campaign is completed to choose colors.

Here is how we will invest backers money into the SideBuddy project:


The SideBuddy was born from an idea that the inventor Jordi Hans had when he was left wondering how to improve bicycle transportation. He saw that most cargo bikes on the market had limited features .

Jordi shared his ideas with interested colleagues and in 2013 our team formed. We began work on a project that we believed could transform bicycle transportation in urban areas.  Allowing to transport multiple combinations with your bicycle or e-bike. Throughout the concept development and  technical development phase more creative features were added as new ideas flooded in. In 2014 a  physical prototype was built   within the first year new partners got interested in the project and we got a little funding from the European Union   in 2015 for  50% of cost for a pre production prototype    in summer 2016 the pre -Dog prototype was ready and after performing technical tests we felt ready to launch our product to the market. 

We believe in our product because it was created to help others looking for an upgrade in how they use bicycle transportation. We have personally tested the product in our own lives, listened to the cargo bike community and worked hard to provide the features they want to see.

Risks and challenges

We've already successfully developed the second prototype in Sweden based on high quality products with our engineering and production team in Scandinavian countries who have extensive manufacturing experience.

Risks are often prone to the unknown. A more relevant risk to the project is of a shipping delay (especially to U.S.A.) caused by quality issues and manufacturing. In order to commit to high quality products, we give quality control a higher priority than delivery schedule. Moreover, we need to get components from suppliers. The more units we order, the more bargaining power we will have. Suppliers usually give priority to bigger customers if there is a limitation to its capacity. To prevent this, we will be sourcing from multiple places. However, we already have 90% of the material all the way through the production process.

Every company faces these challenges, but rarely do consumers see these challenges. Our biggest tool for battling these risks is having previous experience bringing prototypes from concept to full production, including working with contract manufacturers and shipping internationally. We know that building physical goods is a dynamic process with lots of room for hiccups along the way. We will keep an open dialogue with all of our backers through frequent, transparent, and thorough updates.
