Im using a DiD chain now and it's performing well for me.  It's getting abuse too, not a lot of sunday only riding here and it's holding up very nicely so far.

Because speeding cops chasing speeding irresponsible teenagers ALWAYS fixes the problem !!

Queue the Benny Hill music, this should make some awesome pootoob videos.

Try to leave the thing plugged in overnight to balance on an AC charge, try this a few nights in a row.  It will charge up to what it can, balance, might drop a percent or two as the batteries do their thing and eventually balance out.  The battery will also, once charged, try to recharge on it's own every few hours I believe, to try to trickle up if it is still down below 99 percent.

If you have left the bike sit for a long while without a good balancing charge, or many cycles without a good balance, then yes it can give you errors at lower percentages due to the unbalance per battery / per arm, getting bigger as they discharge.

This is not ruling out the possibility that you got a bad battery, but on two bikes?  How long did whomever had them, have them sitting, and did they take care of them properly if they sat for months before being sold?  If they did not charge them properly or store them properly, which I can EASILY see happening with a dealer, then they will act up until finally charged up and balanced properly, for it to get a top reference point.

Ive gotten 75 mph on my Ribelle pushing from 9 to 11 kw to do so.  it was jumping around a bit, obviously but Id say 10 kw is about par for that speed.

Had my Experia updated a couple of months ago, I no longer get the "key not in range" issue and I actually get slightly better range than before the update. It has sorted a few niggles and the system seems a little less "clunky". I've not tried a DC fast charge since the update though.Smithy.

I got the "key not in range" message on my Experia on the ride home from just getting the 43 FW installed. The keyfob was in my right pocket.


Since the time of your post, have you also gotten the message?   I assume so.

v.43 is compatible with all bikes. I don't know why A&S is confused.

Wrong!!!


I took both my bikes in for the FW update. My Experia and my 2020 SS9-


Experia now has the V.43.


Here is what I have in writing from A&S (long story, but they had a cable to do the FW updates after all):


2020 Energica Esse Esse 9- (smaller battery only in year 2020 models):


"Firmware Update V.43:


Description: Customer would like us to attempt to update the firmware to Version 43.


"Resolution: Attempted software update previous SW version was .34, upgrade available was up to .42.


"Performed software update to 42 and checked to see if 43 would become available.  .43 is NOT applicable for this year. Confirmed via searching available technical bulletins linked to Vin." Tech 99 @ A&S @  Roseville, CA


I have no idea what the .42 does that the .34 did not, other than show the version number of "42" in the "About" screen.


I had to rush back to Reno and leave the bike there in Auburn, so I can check it better next time. But that bike did NOT have any bugs, unlike my Experia before the update,

You're in the right ballpark, considering an 11kW gas bike (the legal limit for A1 class 125s in Europe) will do 70-75mph and they have less efficient transmissions you could manage 60mph with less. The difficulty with this question is how does that power vary over the charge of the battery. You could in theory have a bike that can manage 11kW right up until the battery is dead if it's not using the battery to the full potential at a higher state of charge, but most aren't configured that way. And also the power output is generally only listed for a full charge.

If we do a little bit of rough math then a 33kW Zero is pulling roughly 285A from a freshly charged battery, if it can manage the same at 10% then it's down to about 27kW. If we multiply 11kW by that same 1.2x then we get just over 13kW at 100% and 11kW down at 10%. I don't know how realistic that is though, if it scales that way or if more voltage sag at a lower state of charge needs to be taken into account.

Looking at most of the sub-motorcycle scooters - 11kw minimum to get over 100km/h. I recall someone doing some testing on their energica, at 50% SOC I think they were down to 75-80% power output. Continuing this assumption I'd look at least something that delivers a nominal 15kw continuous power

I can't tell you what the minimum requirement would be, however one of the 7.2kW/h Zeros would easily do that and still get you there at a reasonable rate. I think I've had mine down to sub 20% and still been able to get up to 60mph.

I was considering getting a street legal electric motorcycle, but wondering, what all specs would one need if they want to make sure the bike will still hit 60 or 65mph with a battery that's half dead?  I'm like 5'7" 175lb
