“After a few months of problem solving I awoke one particular morning somewhat bleary-eyed after a night of irregular dreams filled with tumbling geometric forms: triangles, double diamonds, a few circles, and—more importantly—arches!

Reaching for the nearest note pad, I quickly scribbled two circles connected at either end by an arch. The patented and proprietary radius frame, “the arc” became the answer.”
Fast-forward nearly a decade to 2007 and the introduction of Pi. This multi-year intensive engineering effort incorporated multiple prototypes, extensive aluminum spar analysis, radius length, shape and battery form analysis, tooling, manufacturing, hybrid propulsion system development and much more.
My original dreamy concept of the world's simplest bike eventually evolved into Pi, the true alternative to internal combustion powered transportation.” —Marcus Hays, Founder and CEO

Is it possible that Pi is the world’s most important electric bicycle? This is not for us to judge but what we can say with certainty is that Pi incorporates the most advanced technology available.

From the light weight, high power LiION batteries discretely located within the aluminum monocoque arch, to a nearly silent multi-voltage 24V/400 Watt, 36V/500 Watt, or 48V/750 Watt brushless flywheel linked to an 8-speed semi-automatic transmission, a suspension seat system  that can easily fit people ranging in heights between 5’2” to 6’8” and providing seated comfort unlike any bike before.
