Orbea Gain battery usage

[Dadam]

I was bored so I made this table of my battery use on some of my rides. The column for assist turned off is the percentage of the time not distance. It's also not very scientific as it doesn't show what level the assist was at when it was on, but representing average assist level across a ride where it changes could get quite complicated.

Bike is a 2023 Orbea Gain D40 XL frame weighing approximately 14.3kg, I weigh approx 90kg.
Battery capacity is 248 Wh

Distance (km)	Ascent (m)	Assist turned off (rough)	Battery usage	Wh/km
84	1812	33%	80%	2.36
102	479	86%	22%	0.53
101	479	78%	22%	0.54
73	1523	79%	45%	1.53
58	1378	4.3%	78%	3.34
51	1248	33%	50%	2.43
50	1157	20%	75%	3.72
47	587	22%	51%	2.69
47	601	24%	44%	2.32
14	152	0	10%	1.77
14	150	0	11%	1.95

One thing I found interesting when looking at the battery stats my Garmin recorded from the bike, was a steady 1-2% drain per hour roughly, while the assist was off. This must be from the lights and the bike circuitry running the internal data capture and the ANT+ connectivity.

Good morning,

That seems to be similar to my experience when using the bike in the rain and it then won't turn off.

It would get through something like a third or half of the charge between Friday evening and first thing Monday morning.

I can't be more precise as I wasn't tracking power levels, but 60 hours at 1-2 watts (best guess) would account for it.

Bye

Added last Saturday's ride, and also a new column of watt-hours per kilometre (Wh/km), because I love data

I have had an Orbea Gain d40i for almost two years. for a variety of reasons i have not used it since December 2024.

I am still a little bit on clear on how it calculates the range. Having fully charged the battery yesterday it was showing on the app 54 KM range. I reprogrammed the custom settings to provide level one at 40% level two at 70% and level three 100%.

Went out for a 46 KM fairly hilly local route today and set it on level one with the plan, not to change that at any point and see how much battery I had left at the end. The last three significant Hills I gave in and went into full power mode using 100% battery assistance for approximately eight or nine minutes in total

Got home and had still got 78% battery and showing a range of 43 KM left. This suggests to me that when they give the range it's based on using full battery power. Certainly the assistance I got with level one being 40% was not noticeable at all in that if you're pedalling on a gentle hill once the speed dropped to 25.5 KMH, it should kick in with battery assistance, which previously was quite noticeable and now it's almost completely imperceptible. Certainly the overall level of assistance men in the Bike felt like a normal non-battery powered bike.

Tomorrow morning, I have a 20 KM ride to a meeting where I want to sit and not be dripping with sweat, so will probably put it on maximum power the whole way!

Is the motor system a Mahle x35? If so...

Level 1 has maximum of 100W, so at 40% you get 40W.
Level 2 has maximum of 175W, so at 70% you get 122.5W.
Level 3 has maximum of 250W.

If you went out and continuously stayed under 15.5mph, constantly using your level 1, you should get over six hours assistance out of a healthy, fully charged 248Wh battery.

But the chances are, on every ride you have periods above the 15.5mph motor cutoff, where battery drain should be minimal and so you get more distance per battery cycle charge.

My Bolt's battery was charged to 97% a few days ago and I had assistance set at 75/80/100% (75/140/250W) for what was a 42min ride last night, where I used level 2 except for ~2mins in turbo. Short downhills without me going mad could easily have got me riding above the motor for 3mins, hence there's still 76% battery charge remaining today and not closer to 70% remaining.
When I head up into the South Downs hills for ~2+ hours, I can easily be above the motor cutoff for ~30mins+, just recently I've surprisingly had a few rides averaging ~16mph, just above the motor assistance cutoff.

Good afternoon,

I have an X35 powered bike and can confirm @N0bodyOfTheGoat 's statement that 40% of level 1 is 40% of 100watts not 40% of 250watts which I first assumed when I played with the settings.

I have mine set up for 50/100/175 watts and the lowest setting is also almost unnoticeable to me as well.

When my battery was in a decent condition it would report a range of around 80km when fully charged, this is more than 1/.78*43 = 55.

I have always found the range to be based on the miles already done and the % of charge required to do those miles with some sort of averaging going beyond a single ride being maintained to give a range when fully charged.

Don't forget that the X35 tapers off power as it approaches the cut off speed, so it probably won't have been even 40 watts of assistance for a lot of the ride.

Bye
