How many wh of battery do you burn in an hour?

Amber Valley Guy said:

Try doing 30 miles/ 48km and 1400m/ 4400ft circuits regularly and you'll understand why we have Eco. Refusing to use eco, is a fools game unless you're only doing short sub 2hr rides.

For me eco feels just like riding my acoustic bike. I have to put in about as much power, and the ebike motor also react weirdly on that mode., so I actually prefer my amish bike over my emtb on eco. (I know I can adjust power curves in the app, but havent bothered). I even feel tour is too slow.

I mostly use emtb or turbo or I don't see the point. Occasionally tour if i wanted a longer ride.
Im also a 105kg phatass, so even at emtb, i get around 800m of elevation and 25km and my 750wh battery is done for.
If I "had to run eco" id sell my emtb and run acoustic mtb instead.

I'm on the fence of getting an avinox power bike, probably would only get an hour of riding if i used its capabiliy. I do ride for the descent mostly, and tech trails.

I really wish we could get new battery tech that could give me about 4 times more capacity (*:

We should share your weight, bike weight.
Your E bike motor type /battery size and travel.

I'm running

Bosch CX Gen5
400wh and 600wh batteries
Bike weight 21.8kg with 400wh and 22.8kg with 600wh.
Bike travel 180mm
I'm 77kg

I've come to the conclusion that I range between 130wh and 260 wh/hr.

130 wh being mostly tour + milking my 400wh battery as long as i can without going into too much Tour +
260 wh being a full boost Enduro race smashing full pace/full turbo the entire time.

PS, I refuse to ride in eco for any distance. I will ride my mtb's before i go Eco on the E.

What ya got team.

Hi!
Power consumption is a linear function if you take power consumption on Y and the ratio (distance/elevation) on X.
NOTE: for "samish" average speed.

I did several TURBO rides, meaning values will equate to maximum battery consumption.



I'll edit this post later today, with my powerconsumption equation.

400-600wh/h if I'm lapping enduro trails at full power. My lowest has been 130wh/h, on a 55 mile, 5.5 hour loop with 720wh battery (last couple miles without power).

110kg, CYC X1 Stealth

If there was a good Avinox bike with removable battery, we could just swap batteries at the van every couple of hours, allowing us to ride all day. But there isn't (apart from the Crestline, which has other issues), so we have to choose another motor or only do short rides. Hopefully someone (not Amflow) will come out with a proper long-travel enduro bike with removable battery, for us self-shuttlers, but I don't think there's anything coming in the next couple of months. The Megamo Ryal is the closest, but you can only run full 29. If the Velduro Rogue, Whyte Karve Evo, Forbidden Druid, or Atherton S170E had a swappable battery we'd be sorted. Such a wasted opportunity.

Generally I'll get 35-40 miles and 3000-4000 feet of climbing out of my 800wh Avinox/Amflow, but I'm hammering pretty hard on a mix of flowy singletrack and technical root/rock terrain (average speeds around 15mph on terrain that I ride at about 9-10 mph on my regular bike). I'm sure I could milk more out of the battery, but that wouldn't be as much fun.

So to your original question, about 300wh per hour. And I weight 170 lbs.

Mate just ordered Amflow with an internal and external battery he's looking for 100 miles out of that.

Looking forward to that equation...

I have limited time on my CXR motor due to injury, but I'm using more than I thought that I would. Elevation isn't that much around here, best I can get is about 125'/ mile, however it's extremely rough and rocky. Weight is 82 kgs & bike is 22kgs (yes, I know I used both STD & Metric, that's where us Americans are now). I seem to use right at 250wh/ hour of ride time.

I gather some informatiin and placed into tables to produce graphs.
Basically, you need to record Battery Consumption, Distance and Elevation --> basic data.

So that you have consistency, I would use always the same mode, and putting as much effort as possible.

*********************************
[EDIT]

You can also verify the power consumption using other modes, you can do like 3...4...5 rides, with different elevations and distance (basically you want to have as much elevation/distance ratios). Plot that data into the graphs, and check the slope of the linear equation. You can do shorter rides, but preferbly on the same Ratio. Eg: set a ride with a ratio of 15m elevation for each km ridden. Do like 10km and store battery consumption. Then do another ride with 25m/km...then 30..40...50... and easily you'll get the power consumption and can determine range on any type of terrain.
This is very useful if you do races (without battery swap), or have a ride in unknown location
]
*******************************


Battery consumption: I used Flowapp to determine the % of power consumed. I've used a 750Wh for all these tests.
Distance: I measured in Kms - you can apply miles, no issue.
Elevation: I measured in meters - you can apply ft.

The ratio between Distance and Elevation is done by using meters and kms --> I didn't converted to the same units.
Afterwards it's just a matter of finding the line that passes through most points (or closest) - you can use Trendline in Excel.
And then, just use the y=mx+b and find slope --> look at google.

As a thumb rule, just use:

15 to 20 meters of elevation per km = ~ 9W/km --> Range: Battery Size / 9W/km = 750Wh/9 (W/km) = 83,3km & ~ 1250m elevation
20 to 25 meters of elevation per km = ~ 11W/km
30 to 35 meters of elevation per km = ~ 15W/km
35 to 40 meters of elevation per km = ~ 17W/km
40 to 45 meters of elevation per km = ~ 19W/km
45 to 50 meters of elevation per km = ~ 21W/km --> Range: 750Wh/21W/km = 35,7Km & ~ 1600m

It may seem complicated, but it's not and really helps on determining the routes to ride, on places I don't know.

NOTE:
This data, is for a rider weighting around 88kg naked, a ebike with CX4 and restricted to 25km/h, and all rides were performed using Turbo and really forcing pace.
The main goal, was to determine real maximum power consumption, and from there determine routes on unknown areas to elaborate GPX and following with GPS.

Using other modes, such as Tour or Eco, will lead to greater range.


hope it helps. Cheers!

Gen 4 840 WH battery. Used 90-95% of it. I weigh 215 or so kitted up to ride. Turbo the whole way.

The newly released / to-be-released Amflow PR does have it. Pretty sure I saw another bike brand also. But yeah agree. WOuld make it very nice to have an extra battery charging at the "camp site": Should be able to charge to almost full capacity before you spent the other.

The PR is not an enduro/DH bike and won't be available for at least a month or two anyway. The Crestline has a long seat tube relative to reach so wouldn't fit me, and is sold out anyway. The Rotwild is super expensive and gets mediocre reviews. The Megamo Ryal is 29er only and not available (or even formally announced) yet, and only 160 travel both ends. I think there is an Italian company that makes one but the geo is bad. That's all the options for removable Avinox batteries, as far as I know. Hopefully there are more on the way, but it seems unlikely in the next month or two.

1400Wh (both batteries down to 0%) in about 4hours of riding last week

So about 350Wh per hour with Bosch gen 5 in emtb+ 80kg rider.

I put myself on a waitinglist for the amflow PX, but i feel the same as you about enduro, I have an Orbea Wild and i love it. ...if I could get it with the avinox, id be perfectly happy.

And with removable battery, which my Orbea WIld dont have, and its the most PITA bike to work on ever. ROuted headset also whcih is a trend that should die.

Not sure if ill actually pull the trigger for the Amflow PX, its prolly more than enough bike for me. I just like the extra safety/margin of error provided by a burly Fox38/Zeb

You'll feel the lack of safety margin.
My trail bike has a PIKE. @150mm/140mm rear, and when I ride the Enduro (170/160) is like night and day! The only thing I really appreciate on the Trail Bike, is how light it is!

On ebikes, I'm really not into Trail type.
