" According to the attached article, which was published in my newspaper yesterday, the U.S. EPA prefers ICE-powered vehicles and doesn't pay much attention to electric vehicles. Likely because ICE keeps them busy testing emissions and dreaming up new pollution rules, whereas EVs don't give them much to do. Not good for their full employment. "

" Literally just finishing up another one of these this evening - latest one had a Zeva BMS as part of the deal and I got some learning related to that along the way.
Worth noting that I've found the vectrix parts lad in Poland to be very reliable and would have no problem buying from them again - wouldn't be keen to rely on them for support though, so you need to go in knowing what you need and how to use it.
David Dugas has made all his stuff freely available, which makes programming and configuring a breeze once you have the Peak PCAN cable.

Might throw up a few pics of the process later if I get a minute, along with a couple of the salient learnings. "

" Hi,
as the kelly only releases full power after approx 15kmh actual 0-80 is not as spectacular as one would assume. Still real fun.
On the other hand it is an almost elastic feel with a smooth transition and is just awesome to ride like that.
from 15kmh on it pulls very nice. Not timed it so i guess comparable to a modern 400 or older 600 bike
Kelly is still on 90 % for bats not jet run in fully.
I already called a buddy so we can take timing and compare to his bike...probably some sunday morning..
greets "

" Hi all,
well the 500 km mark has fallen. No problems with the bike so far, only one minor upgrade had been necessary.
Well after the initial test rides done, i took the bike for some longer rides of course and thus charging times have gone up too.
This revealed the charger getting quite warm if not hot. Not to the point of overheating but i did not like the fact and it surely been a design flaw that i could have avoided if i had used my brain right from the start.
I had thought that the air around the charger and the aditional cutouts in its holder would provide enough cooling to the lower side mounted fan. Well, not the case.

So yesterday being a public holiday i took out the charger, and realised that the fan in it will draw air in centrally and spreading it out through the cooling fins. Which in my case lead to it sucking the warm air in again from the surrounding battery box.
So a few crude big holes were drilled into the plastic and now one can feel the charger sucking in the air below and pushing it out to the sides. Charger does not exceed abut 45 deg C.
Easy fix.
Attachment 8678

Taking the opportunity i had look around all bolts and such, but as using either self-locking or lock-tited nuts nothing had come loose in the meantime.

AS for Autonomy:
Today i took it for a long ride, near fully charged to 97 Volts going down to 84V (3,5V/cell) using 68 Amphrs. Quite sporty driving got me 108 Km/ some 65 miles with an estimated 20-25 km reserve. Which i did not use up for the rain coming in fast. Just made it home 2 mins before the storm hit.
At this voltage one should start to keep acceleration somewhat more easy as i have seen 79 volts ( 3,3 per cell) at full load a few times on the last 2, 3 km.
But still, a solid 100 km or 130-135 ish if one goes a little more easy. I could not be more happy with the autonomy.
Some WOT runs revealed 130 kmh (80 ish mph)on the odometer which, even if not accurate checks nicely against my calculations of around 128 kmh.

All in all i`d say mission fulfilled "
