LEIF Technologies developed an electric version of the freeboard design to offer the feel of snowboarding downhill while on city streets, even if the roads were flat or uphill.
Tandem 360-degree rotatable powered casters are mounted next to each truck assembly and deliver about 5.5HP into the wheels.
The current controller is an off-the-shelf radio remote, which is used to throttle power into the 2000W brushless motors.
18 lithium-ion cells deliver power to the two motors underneath. These batteries are similar to the ones used in Formula One electric cars and even some modern hybrids.
The next phase in LEIF's controller design is slimmed down and simplified.
The LEIF gives you more than the basic powerslide. It has a set of raised center wheels that allow the rider to glide when lifting weight off of the four outer wheels.
3D components are great for mocking up designs and solving missing cabinet handle quandaries, but on a hot day of heavy riding, that plastic tends to get compromised. Luckily, the motorized casters and wheel design are simple enough to swap out parts on this prototype model when needed.
This is where all the magic happens. Various motors and components are tested in order to find the optimal design.
In order to allow for full 360-degree rotation, the prototype's current design has a base made up of flat copper channels.
Power is delivered to the motor through small conductive pads that ride in the base plate's copper channels like the needle on a record. Future designs plan to use bearings instead of these channels to provide smooth rotation as well as conducting the necessary electricity to the motors.
The LEIF board settles in after a hard day on the streets.
