Concept: Chaparral A1 e-Racer by Oberdan Bezzi

08/03/2010 @ 7:52 am, by Jensen Beeler19 COMMENTS

Italian designer Oberdan Bezzi (view our coverage here) is at it again with his pen and paper, and this time he’s set his mind to imagining a battery-powered electric motorcycle. Based off the now defunked Chaparral brand, Bezzi sees the Texan company reinventing itself and entering the electric motorcycle racing scene. The bike has a full carbon chassis, a liquid cooled motor, and great attention to aerodynamics, according to Obiboi. We can also see five removable battery packs on each side of the motorcycle, and single shock suspension used not only on the rear, but also on the front fork assembly.

Wait…we feel like we’ve seen this before…Yes, it seems Bezzi has ripped-off every detail found on the MotoCzysz E1pc, right down to the motor and controller mounting points. Of course the A1 e-Racer looks like the E1pc 1.0, with its square battery packs. Oberdan must have missed our article on the eDD where we explained that the E1pc’s chevron shaped batteries allowed for more front wheel clearance. Imitation is the highest form of flattery, right Michael?

We do like those winglets though…

    Those ‘removeable’ battery packs don’t look like a quick change- looks like every major piece of body work would have to come off first!

    The nose looks suspiciously like that on the new Kawasaki shown a few weeks ago:

  • Not even a mention of the e1pc in his post. Has Oberdan always ripped off designs like this?

    The e1pc looks better.

  • In defense of Obiboi, it’s not like he’s actually an engineer/designer working on a real chassis design/packaging. He does fancy drawings of cool looking motorcycles so his main job is to focus on the asthetics and he does that well enough.

  • Aj

    Does this guy actually have a job designing bikes or does he just do a bunch of hopeful concepts? I see his concepts all over the internet but none of them are even remotely official.

  • Sen Heng, don’t get me wrong, I’ve always loved seeing Obiboi work. Not sure how you can defend him having such a similar design to the e1pc without the mention of Michael Czysz.

    I left a comment on his post. Maybe he has a legitimate reason.

    I’m not sure how you can call it a ripoff of another bike. If the design has any basis on the technology being used to build an actual bike, then the design is within the constraints of possibility provided. The only real similarity I see is the arrangement of batteries, and that’s not really saying much. The frame is only similar in that it’s an obvious motorcycle design, and the body work is completely different.

    To say that the battery arrangement and design is what makes it a ripoff is to say that Suzuki rips off Kawasaki because of their inline 4 cylinder motorcycles. As more people get into the electric motorcycle arena, you’re going to see some designs that resemble others, mostly due to the technology being used.

  • @Nimdae (re: suzuki vs kawasaki) I guess your right in a way but it’s kind of a stretch considering where the development and design of electric motorcycles stands.

    Maybe Oberdan has not seen MotoCzysz’s bike. Maybe I am overly sensitive to giving credit to inspiration. Well see if he approves my comment and responds.

  • Motoczysz didn’t mention in his post.

    What is the problem? we take care to mention! :-P

    In my post I mentioned the EPC1. X-D

    Not escape!

  • @Motoelettriche

    Yes you did, and that’s Peter Lombardi’s photo of the E1pc (a photo he took for us) that you use in your header too. ;)

  • Have checked out the gorgeous E1pc at the TT2010 and make the following comments on the A1 eRacer. Dont understand the battery stacks so ‘high’ in the frame, put the smarts up high (light weight) and the batteries as low as practicable. Why have what appears to be a lay shaft for the output sprocket to chain, wasted space and energy, I reckon the motor needs to go ‘into’ the rear wheel, get rid of all the drive chains, sprockets etc., some Electric Scooters already have this, ultimately forsee motors in both wheels allowing switchable 1/2 wheel drive and regen on overrun/braking. Did I mention Fuel Cell tech….

  • I don’t know off the top of my head how heavy the D1-10 motor is, but I’d guess ~40lbs . That’s a lot of unsprung weight going on there.

    FYI: The word is, “defunct.”

    I would have to agree with Derek; the most logical path for motor development to go is to in-wheel mounting. Different configurations will allow for this, as will advanced structural/thermal analysis, allowing optimized and lighter designs. Really though Jensen, in a road bike (especially race, where the surface is smoother), I can’t see how unsprung weight makes that big of a difference. What’s the max travel of a wheel, 2.5-3 in.?? now rotational inertia, that makes all the difference…

    As to the sketch, though, looks pretty sick…ridiculously unrealistic, but who among us has never drooled over a concept car/bike @ IMS or IAS?

  • Yes, rotational mass is a much large concern, but I still think it makes a big difference when you consider that 40lbs is about 10% of the bike’s weight. Combined with the weight of the wheels, tires, and brake rotors, that’s a lot of mass that’s un-sprung.

  • buellracerx

    Very true. I’d just be interested to see what kind of traction difference it would make…

    Oh well, I guess we’ll just have to wait until somebody starts pouring $$ at the idea
