Electric unicycle

There are now dozens of different battery cells being made by the big manufacturers LG, Samsung, Panasonic, & Sony. For use in an application like an Electric Unicycle, the two qualities that make a particular cell more suitable over another are it’s power output (Amps) & energy density (Ah). Until fairly recently there was an inevitable trade-off between either high-powered cells (e.g. Sony VC3/A123) and energy dense cells—there’s the example of the Panasonic NCR18650B, which had capacity, but could only deliver 2-3 sustained Amps. What has been one of the key drivers in powering the Personal Electric Vehicle revolution, is...

One of the many attractions of an Electric Unicycle, is its inherent simplicity, what could possibly be more efficient than a gyroscopically guided direct-drive hub motor & fitted with a big battery pack? While these machine do not, yet, have suspension, the inflatable tire does a reasonably effective job at giving you a comfortable ride experience. Finding the Right Pressure: The correct pressure is a matter of finding a balance between an optimized efficiency & your preferred level of ride comfort. If the air pressure is too high, then it will not absorb any of the bumps or irregularity of...
