No problem. Went back and watched the Race 2 video. Looks like you're back shifting twice going into turn 1 and then immediately over-rev'ing out of it. I would try sticking with 5th and see how that feels. Also looks like you ran 6th through the final corner and onto the front straight - which may actually be the advantage you had over Pete down the front straight. Does that sound right? If so, I would feel even more strongly that you could run that full course in 5th and 6th. Maybe even give you the option of running up a tooth on the rear if you wanted to play with something else.You're right on in all, Brian. I was in 6 before I came out of the last turn and that helped me to gain going in the straight. I shifted up as we were in the corner before the straight. I was going to try 5 throughout next time and maintain corner speed better. I'll be racing against ICE bikes this next time. I don't think there will be another eBike with me in the two races I have scheduled...so it'll be a little different race. Thanks again for your thoughts.
Yes - peak power occurs around 5k, and then you enter into a "field weakening" zone that attempts to maintain power up to about 8k. The power does start to taper off after the peak, but not so significantly as to say that it is always necessary to shift in a race condition. At a track, you often find (even on a gas bike) that you will run higher revs than you would otherwise run in order to not shift at an inopportune time on corner exit. Having the ability to "hang a gear" a bit longer with little penalty is what four-stroke, inline-four Japanese bikes do very well. The other option you have is to run a higher gear into the corner, trying to maintain corner speed and drive out with plenty of rpm window to work with.Thanks for weighing in Brian. Appreciate the insight. I have some more races and practice at Roebling in two weeks with WERA along with the big bike. I'll try some turns at a higher gear on a couple of corners to see how that feels during practice. If it doesn't mess my rhythm up, I'll incorporate during the race.
Given his result, Bob probably got it pretty close to right to find the correct compromise - in this case, letting the motor over-run peak power a bit on the exits. An area where it might be possible to improve is on the straight, where you're really just trying to maximize your acceleration rate in a straight line. In this case, targeting a shift at 5-6k will ensure that you're getting the most of the power available.
Interesting to see how the fairing allowed you to take the other Empulse every time in the straights.I never looked at it during the race. The video is the first time I saw it.
I was wondering why you spent so much time above 6000 RPM with all the warning lights on. Were you maxed out in 6th gear during those times?
too much fun!Glad to share and enjoyed hanging with the eGang. Looking forward to the next one at RA.
and your first time at this track, great job :
thanks for sharing
I really, really hope it doesn't look like either of those bikes. Call me conservative, but that is such just too much of a leap for mainstream acceptance, no matter how many advantages it has. And considering that right now, electric motorcycles make the most sense in a crowded urban setting, a streamliner fairing just makes no sense. A nice half-fairing like this gentleman?That's my bike! I like the sport fairing look. Naked is fine as well.
Sure. But some recumbent weirdness is a sure way to kill your electric brand (imho).
Thanks for the recommendation. That's a good price! I'm on the right track and going to shop little bit to see what's on the market, reviews, etc.Sounds good. Good luck hunting!
