2011 MotoCzysz E1pc in action

Our buddy Jamie Robinson snapped these pictures for us as Michael Rutter turned a wheel on the 2011 MotoCysz E1pc for the first time. Jamie reports that Rutter was “steady” at the test on the Isle of Man’s Jurby Airfield, likely taking it easy ahead of today’s practice session on the Mountain Course. Not only do these pictures give us a better look at the new bike, but they reveal one fascinating detail: inboard suspension for the front and rear.

Update: Michael Uhlarik explains the suspension.

Update 2: Michael Rutter averaged 90mph in his first practice lap this morning and hit 142mph through the Sulby speed trap.

Czysz locates the 200bhp electric motor in the space where the rear shock traditionally mounts. Relocating it under the tank helps centralize mass and make room for that motor. If you’re sitting on the bike, the left shock controls the rear suspension, the right shock the front.

The 2011 E1PC uses a simple pushrod and bell crank system to articulate the rear shock, which is mounted on the “tank.” The large diameter carbon fiber rod (pictured above, it’s wearing a yellow Race Tech sticker) on the left side of the rear tire is pushed directly by the rising rear swing arm, which gets translated from vertical to horizontal movement by a bell crank (which is basically a triangular pivot).

We tried this on the first full scale design mock up of the Amarok P1 (below), for the front end. See picture below. We ditched it in favor of using the space for electronics.

MotoCzysz hasn’t yet released full specs, but over the 2010 MotoCzysz E1pc it has these improvements:

50mm shorter wheelbase for quicker steering
better/ideal weight distribution
more rear wheel torque (up nearly 30% over 2010)
60% improvement in horsepower (nearly 200hp)
improved/extended torque curve (redline over 10,000rpm)
more energy on board (amount undisclosed)
reduced overall weight by over 25lbs  (under 500lbs)
improved aerodynamics
significantly overall higher efficiency (near 20% at 100 mph)

Michael expects that the bike will be more than capable of completing a 100mph average lap of the 36.6-mile road course. Something it could do as soon as today’s practice.

    Interesting to see early stages of electric bikes changing form factors…

    I wanna see that suspension up close…

  • Esteban

    First of all thank you HFL for posting this..
    this one of the most exiting bikes being born now, keep it coming! is segway a team sponsor only or has some tech behind it also? maybe both.. the suspension design is very interesting
    I WANTA RIDE

      Segway’s a sponsor. We’ll have more pics and more info later today.

    The bike looks, goes and even sounds fantastic! Rutter was obviously holding back throughout the lap but gave it bean through the Sulby speed trap and across the line. Here’s a video of the bike being wheeled out (after all the other bikes had left!) into the pit before it went on to overtake everything else! http://www.youtube.com/watch?v=qzaL9HkFtNY

    Picture 16 would suggest that only bike #2 has the shocks where the fuel tank would reside. While bike #1 uses traditional placement, at least in the rear.

      Read back a few articles and you’ll see the team is running two bikes. This new one and an updated ’10 model.

    Tony Foale used to work for Segway for a while – any connection with this?

  • Gene

    Hope this works better than the battery powered lawnmower & tools I’ve used. For me, “battery powered” == “crap that lasts 3 charge cycles and dies”

    I sure wouldn’t trust it for something as important as my transportation.

    • Mule

      I don’t think this is intended for your transportation and I would guess the battery, motor and controlers are a couple clicks above a Black and Decker lawn anything. Every component related to the electronics on this rig are probably in the tens of thousands cost wise and further, electronics have advanced quite a bit since introduced over a hundred years ago. For instance satelites, television, stereos, auto electrics etc seem to me to be as relaiable as hell in the 21st century. That is, everything except electronic implements intended for yard maintenance.

  • Terry

    With this arrangement, would it be possible for the rider to make suspension adjustments on the fly?

    Around 2003 we started with our Morlaco concept the first concept had a twin shock layout:

    Offcourse with and ICE engine the task was a lot more difficult; fueltank, airbox, etc. so in the end we ditched the concept but still wanted to use it for an electric engine motorcycle (here’s the sketch: http://s3images.coroflot.com/user_files/individual_files/134713_bQBhV_tdtb9sOWCSYbbe6uAjj.jpg )
    so I was very surprised to see the pictures of the Czysz so is Mr.Czysz a reader of our blog ;)

      You guys do such neat stuff Hugo. How’s that Buell coming?

        I think David will show something new in the next two weeks, going forward and looking good:)

    Where do you hold the pizza boxes though? j/k
