Range vs speed.

We know it is related but has anyone tested the diff between 80, 75, 65, 55 MPH? I generally just assume 80 miles at 80. But I haven't really tested. Going on a 500-600 mile weekend trip. Trying to see what to test to figure it out. Not like going 55 I5 is an option. But might go back the slow way.

The stupid Livewire app actually estimates like 130 miles on a trip using the interstate. That is just nuts to tell people that will work.

At an average 185 km/hr on the Autobahn between Frankfurt and Munich, no luggage, tucked down, minimal profile - I got exactly 93 miles / 148 km before I had to pull over with 2% charge... on a rental LW.

And I got passed by two Teslas and a Porsche. :mad:

But no-one else ;)

OMG How could you average 185kph when that is the top speed? That's just insane. You should have taken it to the Nordschleife :)

Weird. That is way better then I did. I am big and heavy. But you would think at speed? Maybe the big wind screen isn't great for efficiency.

You are of course completely correct, I miswrote :) that was my maximum speed. I got onto the Autobahn a few k's south of Frankfurt, from memory via the Neu-Isenburg on-ramp early on a spring dawn day, and cranked the throttle to the absolute maximum. Because, why not. It was legal, and I was alive.

The average left-lane speed was registered on my GPS, = I was too busy watching in front of me and beside me to look at the realtime speedo on the LiveWire. So yeah, the 185 km/hr is from my GPS and not a real-time average.

I denounce myself and will report for re-education :)

Right on. I haven't had the opportunity yet to try a top speed run as I have only had mine since December. Wish we had an autobahn around here. According to the Harley app the top speed I have hit while out on a ride is 739kph! Lol.
I did not feel it cut out but I did see 110mph for a second on a high speed run recently. Closed course of course etc etc.

My speedo overstates actual speed by 2 MPH at 60. So, I set my cruise control to 62 mph (displayed) and do 90 miles at a stretch and that's consistently the break even point where 1% of battery capacity = 1 mile of travel. If I go to 70 displayed, it's about 0.8 miles per percent of battery. Overall I was quite happy to consistently hit 100 miles of range at true albeit in the right lane nominally at 10 mph under the posted speed.

Sorry, my omission as I saw it mentioned in a subsequent post. I have a Puig windscreen installed. Without it, the result would be lower miles per percent charge.

This aligns with what I saw but didn't measure.

So the range is something like:
50 mph =
60 mph = 100 mile range = 1 x % left
70 mph = 80 mile range = .8 x % left
80 mph = 70 mile range = .7 x % left
90 mph =
Discounting head winds, wind screens, rider size, tire pressure.
The more I think about it the right way to fix this up is via some sore of gps tooling and access to the battery state.

I do notice that the one screen does show a kW per mile rate but it seems to update over a large average rather then being the current run rate.

What we really need is the instantaneous kW per mile and a more detailed battery level. Also has anyone else noticed that the percentage of pack usage isn't super linear? It might be in my head but I notice some pretty quick jumps in the 20's and 10's of percent. How is the computer calculating battery percent anyway? I am not familiar with how that work.

I have nothing amazing to reveal here. My longest ride starting out with 100% was 103 mi (166 km), with 14% remaining. If I had taken it down to 2% like Oldun, I believe that would have been 117 mi (188 km).
This was riding on non freeway, two lane roads, riding with traffic, mostly +/- 50 mph (80 kph) only accelerating a couple times to pass cars, not all of it was on flat ground, there were some hills.
And like Oldun, no luggage. I tuck down a lot, at anything over 40 mph (65 km), not only when I’m going for speed (I’m usually going for distance, DC chargers are few and far between where I usually ride, and L1 chargers are almost useless when your trying to compete a longer ride in one day). Don’t get me wrong, I like the esthetics of the Livewire, but somebody has to do something about the drag coefficient, because the Livewire is about as aerodynamic as a brick, so I do what I can with my body regarding frontal area.

I started to Write about battery temperature and range, because it drops off noticeably in cooler weather. but I think I will try to start another thread, unless someone beats me to it.

I keep a spreadsheet of all my charging, service, and other bike-related expenses, so I can document this post fairly well. I rarely ride the Interstates unless I really need to -- they're generally too boring and frankly, I usually have the time to take more scenic, if slower, routes. The one time (October, 2021) I did take a longish ride at speed was 66 miles from Portland, ME to North Hampton, NH. I left ME with a SOC of 100% and an estimated range of 110 miles. I had to stop in NH to charge because the bike showed an SOC of 18% and an estimated range of 18 miles, and I was ~22 miles from home -- extreme range anxiety had set in as I had only had the bike for three months and was still getting to know it. I tried to keep a steady speed of 75 MPH on this trip, however there were a couple of burst to 85 MPH to pass semis, and a couple of dips to as low as 55 MPH for traffic and tolls.

This was before I had installed the Puig windscreen; I'm 5'8"tall and weigh ~260 lbs. in my usual riding gear. I'll be reversing this trip once the weather gets warmer and I bring the ELW to our summer home in ME (there are some awesome riding roads in the midcoast region of ME!), and I'll be interested in seeing the impact of the Puig. So far it's added about 10 miles to both estimated (by the bike) and actual range achieved at my usual back roads "donking around" average speed of ~35 MPH.

I have found that if I keep off the superslabs the stated and achieved ranges line up quite well; I'd guessimate the variance to be <2%, which is close enough for jazz.

I guess this all just proves the (in)famous phrase, "Your mileage may vary."

Yeah I think my riding has too much variation where I find the estimate would be very sketchy to consider accurate. Often suggesting I have way more range than my current rate would suggest. In the city my range is irrelevant as I have never needed a charge on my normal usage pattern. It only becomes and issue on the highway. I suppose if I didn't have a garage and had to use high speed charging more regularly it might start to add up. Where as now typically I wait till I break 50% on a couple rides then plug in over night and am done. Would love to get a good understanding of the temp effect.

Thank you for the above commentary and analytics.

With only a couple of exceptions I've never been that detailed and analytical in my LW rides, but I know where I can get to in back on a "tank". But I'm lucky because I have a old-fashioned touring motorcycle for the really long trips (a Dyna with custom saddlebag tanks).

That said, riding to a nearby city I plug it in on level I and that gives me just enough extra juice to get back without going below 10%. On some days I am faster and some days I'm slow and it's too much of a headache to 'ride to the battery level', so I just top it up when it suits me.

Would level 2 change my riding pattern on the LiveWire? For sure. But it doesn't have it, so I don't fret about it. I think Level 2 is the singlest most smartest thing that the H-D monolith could do to sell more EVBs, but they haven't been asking my opinion on anything lo! all these many years :)

It was a weird choice. One could argue plain l2 would have been plenty. But I think the assumption is that l3 will be every where. I certainly would not have taken that last road trip on a level 2 only bike.

I have to say it's surprising that HD hasn't asked for input given the relatively small but mostly loyal owner base. So many companies these days are sending out satisfaction surveys for movies, products, services and even food all in an effort to find out what their customers like and don't like. If they stuck their head in these forums once in awhile, not only would the owners probably get some good tips they might feel like their concerns were being heard and possibly considered in regard to changes that could potentially increase sales. There's nothing like a satisfied customer to promote a brand!

I think it is very odd there isn't any effort to connect with the online communities. It is suspiciously absent. Even so much that they must be actively prohibiting employee present in these forums and groups.

I agree, if H-D / Livewire or who ever, is supposedly trying to build an E-motorcycle that is marketable, than they would want to improve upon their existing E-motorcycle. And one would logically think that they would be actively looking for input from those who have real world experience using their existing E-motorcycle.

I can see no evidence of such inquiries.
Which suggests to me that the agenda they are projecting, is a little different than the agenda they are hiding.

It seems they should be collecting information on the existing product so that they can improve on their next generation of E-motorcycles, which would afford their hyping the next gen as “new and improved.”

But with all the data they are able to collect from the H-D / Livewire app, maybe they have figured out that it’s more reliable and way less complicated than eliciting info from a living, breathing life form. Like Joe Friday used to say on the old Dragnet series: “just the facts, Ma’am”, I realize, I need to remember that saying, because my post are way too long.

If their agenda includes keeping everyone in the dark, then they have at least accomplished this portion of their agenda.

The app has never worked in New Zealand on my ELW, and indeed it cannot even be downloaded onto a New Zealand smartphone.

When I rented an EWL in Europe, the app was not available unless I purchased. So, no.

When I rented another one in the US, I could can download the app but couldn't use it unless I owned the motorcycle. So, no.

That said, I don't miss it the app-screen interface because (a) basic philosophy about don't wanting what I can't have and (b) I assume it consumes some battery life and I already have too many fat cells that leach battery life as they are ferried around and (c) on all forms of fast transportation, I don't want my eyes off the road and other road users. I would absolutely pay top dollar for a line-of-sight heads-up display (for speed and gear, but of course wouldn't need a gear indicator for the LiveWire) such as the HUD I briefly experienced when test-driving a Jaguar iPace a while back, but I've never found one that works well on a motorcycle.

I've never wanted to listen to music while riding. For me it's about the ride not the soundtrack unless I have to supply an occasional soundtrack of profanities, phews, damns, yikes and assorted other event markers.
