At the 1-mile timing location:



It's a pic on book of faces (group called Loring Timing Association).  I'll look for pics for those who can't see it.

Good job Brian - personally I would love to learn more about your pack design and any construction tips you might have.  Getting anything to survive and work well at those temps is an outstanding achievement.

Back to batteries: I like pouch cells and have never used anything else.  But in planning my next build I'm finding that it's hard to identify quality cells that are available to the average hobbyist.  There's all sorts of cylindrical cells out there that anyone can buy though.

Hub motors leave more rooms for batteries, controller, but are heavier so impact handling.  There's also an advantage not having to worry about motor mounting, chain run, etc.  I remember seeing a Buell Blast with an Enertrac and the guy was happy with it.  Re axle diameter, brakes, etc. - you'll have to figure all that out.  Maybe contact Enertrac for their advice?

It still looks like a bunch of design goals, specs and computer renderings to me.  It's great marketing (and I really hope they can deliver on some of their claims) but until there's some sort of independent verification...

If they really can deliver 200 HP/200 Nm torque in a 48# motor- kudos to them because I don't think anyone else has been able to do so.  But the numbers seem a bit convenient i.e. 200, 200, 200 HP, nm, MPH.  I haven't actually signed up for a test ride yet but I did confirm that they intend to market in both the US and Canada.  Once they actually start production I would love to try one out but I would expect them to focus on population centers and that's about the polar opposite of where I'm located.  Maybe I should sign up, just to let them know someone else might be interested in the eastern part of the continent.

There is not an infinite supply of fossil fuels and all the easily extractable oil is already being accessed.  How can we build any kind of future on energy technology that is not ultimately sustainable?

I suppose I have a unique perspective on, and a vested interest in, this project as I'm one of only a few people in the world to have ridden an electric sit-on motorcycle faster than 200 mph, and the only one (as far as I know and I do pay attention), to do so using OEM bodywork in a street-legal configuration.  Here's video of one of my runs at Loring (Limestone, Maine):



This bike (converted 2004 Suzuki Hayabusa) runs 94 mph at my local 1/8-mile drag strip with no changes.  Gearing is 17/42.  I have ridden (on the street) with a 65-tooth rear sprocket and had to limit torque to 50% to make it streetable: acceleration is pretty intense with that gearing.  A couple of years ago, Motorcyclist raced a Lightning LS218 against a Kawasaki H2 and the Lightning did 144 mph in the 1/4-mile with a 66-tooth rear sprocket.  Big sprockets make you accelerate quicker and with that much torque/power the Voxan should be a beast in standing start racing.

Voxan should be more forthcoming with how they took their measurements.  Perhaps they did use a parallel runway somehow to get more room to accelerate but they should be up-front about it (although I can't visualize how this could work).  I've been very involved in LSR for more than 10 years and have personally witnessed thousands of high-speed passes at Loring.  I don't know how they could do what they're claiming, in the distance they claim to have used and still accelerate to speed then stop safely.

The bike's never been crashed, but it's been dropped a couple of times - once at the track doing photo shoot maneuvers in the pit lane and another when it fell off the dyno when the front wheel chock failed.

I use polycarbonate for my packs; my only crash experience was one time my drag bike was parked in line and a guy on a bicycle ran into it (I kid you not).  I was talking to a friend by his car and heard the crash and thought "that sounds like someone's bike fell over" - turned around and it was mine.  The guy on the bicycle (I think he was drunk) stands and yells "I'm okay!  I'm okay!"  No damage but I wasn't that happy with him, lol.

You are correct about the motorcycle: Amarok.  I've tried to get in touch with them as our place in Nova Scotia is only about an hour from the Halifax area but no luck.  I don't think it was that quick, but it was quite some time ago - technology has advanced a bit since then.  They actually ran it at Pikes Peak.  The track scenes in the video are at Atlantic Motorsports Park, where I do track days.
