I think the only way I can really describe the ’09 Motoczysz E1pc is with the word “exquisite”.
The bike is one of the highest evolutions of race-bike frame and chassis design, and Michael Czysz is no stranger to building competitive machines. It represents what looked like on paper, back in 2009, the best possible, conceivable, powertrain – a triple Agni 95r configuration. Hell, everything fast was running two Agnis, why wouldn’t three be better? In their “Design Briefs”, Michael outlines the goals for 2009: “…build an electric bike… and we barely accomplished that. Although we had the most energy and torque, we had the least knowledge.” Michael isn’t a big advocate of KISS design principles, but no one can say he doesn’t dive into the deep end.
What I’ve always loved about the Motoczysz bikes was the battery pack. Of course, I love it because it was conceived as a “hot-swap” modular design, right? But it’s also a really sweet hot-swap design. Who can look at that bike and not think “shark”?
Also, the frame. Purpose-built for an electric drivetrain, and 3 Agnis to boot. Here:
This was the CAD rendering for the frame, and the specs on the Motoczysz page say it’s a “frameless Carbon Fiber” design. Not sure what that exactly means… but here are the rest of the specs:

Here’s an actual shot of the bike:
Strangely, there aren’t a lot of photos of the bike out there… just a few on the Motoczysz website, here.
But yeah. This bike was a point in time when this stuff was just starting. A lot of talented people were running a lot of interesting numbers and models, and some of them worked, and some didn’t. This was sort of a shining moment in electric motorcycles when there were exciting ideas waiting to see what worked in the real world.
From there, Motoczysz went on to, this summer (2013) kick some serious ass at the Isle of Man. Here’s the rundown on their progress from then, in 09, to now, from a blog entry:
In 2009 the goal was simple- build an electric bike… and we barely accomplished that. Although we had the most energy and torque, we had the least knowledge.
In 2010 we focused on an integrated electric drive system; we debuted the MotoCzysz D1g1tal Dr1ve.
In 2011 we focused on better handling dynamics and very purposefully, suspension; we debuted a twin spar CF frame (with flex), CF oval front forks and a F1 style push rod suspension.
For 2012 we focused on overall vehicle and system efficiency; we will debut possibly the most aerodynamic road racing motorcycle to date.
In 2009, the bike didn’t finish the Isle of Man TTXGP IOMTT race. The multiple Agni idea has been dumped by just about everybody serious about going fast, mostly because of issues controlling more than one Agni motor. I seem to remember reading an entry somewhere about Cedric Lynch (the guy who designed the motor) not even being able to time and sync the motors, and almost every race-motor fire you’ll see on YouTube is an Agni, and the brushes burning up.
But I’ll always look back at the 2009 E1pc as a remarkable first step that set the stage for what was to come…
