BOXX electric bike: two wheels, four corners, all-electric transport for one — Engadget

Has bicycle design reached its pinnacle? Or are electric bike manufacturers just not trying hard enough? The YikeBike begs to differ, and here joining it is BOXX Corporation’s diminutive BOXX. Coming in at just under a meter (or 36-inch inches) long, the 120 pound aluminum “bike” has a top speed of 35 miles per hour and can even haul up to 300 pounds of heft. Yet, despite that compact footprint, the company hasn’t skimped on tech, as it boasts traction control, anti-lock brakes and yes, even LED lights. Available in one of ten colors, $3,995 nets you a base 40-mile range model, which can optionally be doubled to 80 by ticking the $599 CORE 2 box.

So this is was my senior project.  It was a 1974 Suzuki 750 GT.  It is now an all electric motorcycle.  We built it for around $2100 as proof that a cheap and efficient electric motorcycle is possible.  Just because its not at the bleeding edge of the tech does not mean its crap.  We researched and found that the average person’s commute was around 20 miles so that was our goal to hit.  We got the bike for cheap ($200) and motor and controller and batteries made up the rest of the cost.  Its got a top speed of 50 mph so it can be driven off-highway to an office or place of work.  Its got an extension cord built into the gas tank along with a charger that charges the 50Ah lead acid batteries in around 8 hours (overnight or during work).  This is a perfect example of engineering; its multi-disciplined covering mechanical and electrical and it was all about time and money (we had very little of both).

If you would like more information its available at the website I set up for it at Sae.wvutech.edu/projects/electricbike

Its got videos, photos, and a lot of documentation.

Yep that would be me in the billabong shirt and riding the bike.  I started another blog about engineering in general.  This covered both so I posted it there first since I have posted about it before on here when I started this.  Enjoy!
