I love having big wheels on a skateboard because they allow you to go faster without compromising the smoothness of the ride. However, the problem with having big wheels on a regular skateboard is that it raises its center of gravity producing a higher risk of tipping over while making sharp turns. This makes big wheels particularly not suitable for downhill. I wanted to create a skateboard that offers a ride similar to a snowboard but with the power and the control on turns experienced in roller-coasters. So I designed a system of parallelogram linkage trucks that move jointly at specific angles, allowing the wheels, for the first time ever, to lean into the turns.

Testing prototype at 35 MPH ~ 56 KPH
Steering is also enhanced with a simple four-bar linkage system which is attached to the board, giving every joint two rotational degrees of freedom. The freedom to do 35 mph, and the freedom to not shed any skin while doing so. - hiconsumption
Comprised of a system of parallelogram linkage trucks that move jointly at specific angles, the truck allows the wheels, to lean into the turns. Take a peek at the video for a demonstration - longboardism

There’s nothing better than bombing down a steep hill on your longboard, but let’s be honest – we’ve all dreaded that potential wipeout. Enzo Prathamesh felt the same way, and decided to create the Lean Skateboard, a long board that’s better adapted to high speeds. - DESIGNYOUTRUST
Well today we introduce you to The Lean Skateboard a new way to enjoy the warm weather, while ripping up the streets in the process - stupiddope

Why and how Leaning is better and let you you go faster?
The same reason as motorcycles or bicycles lean into turns. Roller coaster tracks are designed in such way that ride always lean into turns. NASCAR tracks are inclined on corners.
How does it lean into turns?
Whenever the rider leans his/her body into a turn, the Lean Board’s wheels lean into the same direction. The steering mechanism is a simple four-bar linkage system which is attached to the board. Every joint is designed in such a way that it has two rotational degrees of freedom (Red and Blue arrows). In the XYZ coordinate system, the origin is at the center of the steering. The parallelogram linkage system's center part is perpendicular to the board. When the board is pushed down towards the direction of the turn then the wheels rotate in XY (Blue) and XZ (Red) plane. The Lean Board’s steering is designed in a such a way that all joints rotate in both XY’ and XZ’. These planes rotate at the same time causing the wheels to turn in one plane and lean into another plane. The center axis of the wheels is the intersecting line of XY’ and XZ’ planes. Each wheel has an individual axis which moves in a Conical shape, making them turn in 3 dimensions. The lean board's spherical wheels let it lean and rotate at the same time in a smooth manner. Moreover, they are big enough to go over any moderate crack making the ride smoother.

How will the funding be used?
Our patented design has been built and tested on several prototypes making a product that we believe meets our demand for highest quality and performance standards. Now the project is ready for production and with your backing, we can take it to the next step so that the whole world can enjoy it. Your contribution will be used to cover the initial manufacturing and tooling activities. These activities includes the fabrication of a molding tool for the wheels, obtaining all raw materials, the custom machining for each part, warehouse fees and product packaging. Join us and be one of the first to experience this new one of a kind skateboard technology!
All design are Patented.
Risks and challenges
Since this project involved doing something that had never been done before, I had to incorporate a lot of unorthodox design solutions in order to achieve my goal. Every obstacle that I faced throughout the iteration process carried a lot of weight on my shoulders. However, it was with great enthusiasm that I was able to overcome these preliminary challenges and I will continue should any further issues arise.
We will keep everyone posted if any hurdles come across the way and we will do our best to come up with a great solution in a timely manner.
Lean Board's trucks top plate dimension is exact same as regular skateboard trucks.
so if you have regular skateboard then you can replace its trucks with Lean trucks.
Please read 'How it leans into turns' on the Kickstater post.
Back in 2002 BMW introduced the $500.00 “Street Carver”.
There is a big difference between both technologies.
Lean Board's wheels move on a conical surface, wheels move individually.
Our design makes ONLY the WHEEL lean and turn but on the BMW the whole truck system moves (two arms).
Also BMW trucks didn't have any damping system to push you back up but our design has that.
BMW skateboard didn't have low center of gravity (lower ground clearance).
Our design was not derived from the BMW skateboard.
Read my story that explains how I came up with this skateboard.
We have designed this trucks so that they are fully customized.
Our wheels will have different durometer (hardness) and the bearing are standard size so you can replace them with one you like.
