How It All Began Principal

The Unlimited team is based on friendships that go back 20 years. A group of engineers with complementary skillsets and a share passion for technology, outdoors life and changing the world in a big way! In this blog post, we tell our story, read on and enjoy!

Unlimited started in 2015 as a personal project looking to solve a real problem. After graduating from MIT, Carlos was living in San Francisco and facing the classic “last mile problem” in his daily commute to Palo Alto. That awkward distance that’s too long to walk but too short to make another bus or metro ride worth it.

Carlos has always been into skiing, mountain biking, surfing, skateboarding, so he thought it would be fun to build a DIY electric skateboard that would serve this purpose. A bit over-powered and under-engineered, this first prototype still proved the point! It was insane! The commute turned amazing and it was suddenly super cool to pickup groceries or go to the pharmacy!


Carlos knew Juan Pablo (JP) from way back in college,  and after this first prototype they started working more seriously on a new motor design. The goal was to make a stealth in-wheel motor and reduce rolling resistance making the ride feel just like a normal longboard.

They built several prototypes more, both in California and Europe, as JP was doing his PhD in Valencia at the time. The rides were so great that they started thinking about making an actual product out of these designs. From that moment it was clear that such a project would call for an electronics ninja, and it turned out that they knew just the guy.

JP knew Alejandro also from way back in college too, and more recently they had met again in Valencia, where they co-founded the Formula Student team at Universitat Politecnica de Valencia: now a top 3 team worldwide!

It wasn’t hard to talk Alejandro into this project: What? Challenges? Lots of chips and testing/breaking things up? That is almost as cool for him as chocolate is, although not quite!

Unlimited was then officially founded in 2016 by Carlos, Juan Pablo and Alejandro, and Andres and Nicolas came aboard shortly thereafter. Along the way, the team has grown and we’ve worked with all kinds of awesome people, but this solid and relentless team of 5 has always been at the core of Unlimited making the magic happen!

Developing our tech

Shortly after founding the company, we launched our first Kickstarter campaign, and it was a great success! We were joined by an amazing community of backers who loved the product we proposed and provided great feedback we used to improve on. We then faced the challenge of moving from perfectly functioning prototypes to a product that could be mass-produced, was reliable, performing, etc.

The goal was not only to make it through production of those skateboards, but to actually support a company based on a cutting-edge technological stack that could then be a platform to build on. Unlimited’s vision has always been about powering and connecting a full network of all kinds of light electric vehicles. To accomplish this fast and successfully, we had to build and integrate the whole system, from the powertrain through the cloud.

How It All Began Unlimited Eskate Parts Signals

How It All Began SignalsWe spent months completely dedicated to carefully building the best light electric vehicle technology.


All together, this meant the team had to go through a huge tech development process full of challenges in battery management, motor control, Bluetooth communication, Android and iOS, just to name a few.

We spent days on the motor dyno, burnt stuff, broke stuff and went through countless prototypes and iterations, but it was worth it. The team learned, our suppliers learned together with us and the technology evolved into a neatly integrated modular system. Tech development never ends, but accomplishing this first step definitely felt like a win for our team!


The skateboard chapter

We packaged this tech as a product in the form of an Electric Skateboard Kit that gives users options in terms of weight, range and power. An unparalleled, easy to install kit offering the smoothest ride and upgradeable over time. Customers decide how their ride will feel by combining the system’s modularity to their choice of board. We started shipping out of our first pilot run in 2018.

Later in 2019 we met the amazing team at Loaded Boards and it was very clear that putting Unlimited powertrains on the sweet decks built by Loaded was something people would love. Since then, Unlimited and Loaded have worked together to redefine what’s possible in electric skateboarding and just having fun out in the city.

We improved the system, included sweet Orangatang wheels in all products and launched a totally new board with them, with customers now in over 80 countries!


The ebike chapter

Bikes have always been on our minds. You can even see a very early prototype in our Kickstarter video from way back in 2016:

How It All Began Early Ebike KitOne of the very first ebike prototypes we ever put together.


Not only do we love mountain biking, but we are also huge believers in bikes as a great way to move and one of the clearest paths towards sustainability. With a full tech stack already in our pockets, we had the flexibility and opportunity to then apply it to all kinds of vehicles. So after the skateboard was out in the market we embarked on the development of our 2nd generation powertrain and completed it first for bikes.

How It All Began Prototype Ebike KitAnother ebike prototype, this time built out of production skateboard batteries and controllers.


Our second product, an eBike Conversion Kit, allows customers to convert any bike to electric in minutes. We set out to design a product that really simplified how people perceive an electric conversion kit. No messy wires, no complicated matching of parts. Just one wire going from the powerpack to the motor, while pedaling is detected by our smart wireless pedal sensor. This sensor was an industry-first and after key validation steps we were ready to bring it to market.

How It All Began Big Plus CreamThe prototypes we built for the Indiegogo Unlimited eBike Kit product launch.


We launched the product on Indiegogo in the middle of the COVID-19 pandemic. Putting the campaign together was a challenge and getting the product manufactured and shipped was 10x more challenging. We’re very proud of that achievement and continue working day and night to improve the product in its early days!

While launching to market with Loaded Boards in 2019, we got into Techstars, one of the best startup accelerators in the world, with a 1% admission rate! Techstars has different programs around the world to fit all kinds of startups. We went through Techstars Mobility Detroit, at the very heart of the place that saw the first mobility revolution back in the Henry Ford days. The program was managed by Ted Serbinski who has been not only a great mentor but a good friend too.

This was a mind blowing experience for our team, 3 months of intense mentorship, coaching, pitching all whilst still running a business. It’s like going to business school in 3 months with your own business running live. We learnt tons about our own company, about our strengths and weaknesses and developed a clearer vision on how to build a solid, world-class business.


The future ahead

It's estimated that 3.5 billion micromobility vehicles will be on the road by 2035, and we believe most of them will be owned and affordable.

There’s massive value to be captured from connecting these vehicles and creating an ecosystem that also includes accessories, apps, software and services. Unlimited aims to unlock this value by building a platform that includes powertrains (batteries, inverters, motors and everything that moves the vehicle), connectivity, software and the necessary APIs so that 3rd parties play a part.

Exponential growth will come from the Platform giving 3rd party OEMs, retailers, developers and service providers the hardware and software that will enable them to easily be part of this ecosystem.

COVID-19 has presented a unique opportunity to grow further as micromobility skyrockets. The team has a clear vision of this future and we will work tirelessly to see that vision through!

Join us for the ride!
