E-Bike energy consumption: How much electricity does an e-bike consume per 100km? Surprising result.

Wie viel Strom braucht ein E-Bike für 100 Kilometer?

Habe mir das für mein E-Bike (ADO A20S) ausgerechnet und zwar unter Real-Bedingungen. Nicht die beworbenen Werte, sondern, was es tatsächlich im Betrieb, so wie ich es verwende, benötigt.

Fahre das E-Bike in der Stadt in der geringsten Assistenz-Stufe (Stufe 1) mit der maximalen Geschwindigkeit 25 km/h, so weit das möglich ist.

Damit komme ich bis zur Batterie-Warnung auf circa 60 gefahrene Kilometer. In Stufe 3 waren es ungefähr 50 Kilometer.

Der Akku ist mit 345.6 Wh (typical) angegeben. Das würde auf 100 km dann circa 0.6 KWh ausmachen, wobei der Akku allerdings nie ganz entladen wird. Andererseits muss man auch noch die Verlustleistung beim Laden berücksichtigen, was den realen Energiebedarf noch um 25-30% erhöht.

Komme so auf circa 0.75 KWh realen Verbrauch auf 100 km. Das ist erstaunlich wenig. Ein Elektroauto benötigt per 100 km zum Vergleich 20-30 KWh, circa das 30-fache eines E-Bikes.

Ein E-Bike benötigt real sogar weniger als 1 Kilowattstunde für 100 Kilometer. Angeblich sogar weniger Energie als wenn ein Mensch die 100 km mit reiner Muskelkraft fahren würde, da der E-Motor effizienter ist als die Beine eines Menschen. Allerdings muss man bei Pedal-Assist-E-Bikes nach wie vor selber treten. Richtig effizient wäre das Ganze, wenn man gar nicht treten müsste. Aber dann wäre der Workout-Faktor wiederum geringer.

Was sagt ihr dazu, dass E-Bikes so wenig Strom brauchen?

How much electricity does an e-bike need for 100 kilometers?

I calculated this for my e-bike (ADO A20S) under real conditions. Not the advertised values, but what it actually needs in operation, as I use it.

I ride the e-bike in the city at the lowest assistance level (level 1) at a maximum speed of 25 km/h, as far as that is possible.

This gets me to around 60 kilometers before the battery warning. In level 3, it was about 50 kilometers.

The battery is rated at 345.6 Wh (typical). That would equate to around 0.6 KWh per 100 km, although the battery is never fully discharged. On the other hand, you also have to take into account the power loss during charging, which increases the real energy requirement by another 25-30%.

This results in a real consumption of around 0.75 KWh per 100 km. That is surprisingly low. By comparison, an electric car requires 20-30 KWh per 100 km, around 30 times as much as an e-bike.

An e-bike actually requires less than 1 kilowatt hour for 100 kilometers. Allegedly even less energy than if a person were to ride the 100 km using pure muscle power, as the electric motor is more efficient than human legs. However, with pedal-assist e-bikes you still have to pedal yourself. The whole thing would be really efficient if you didn't have to pedal at all. But then again, the workout factor would be lower.

What do you think? Have you known that e-bikes need surprisingly little power?

War mir bekannt, aber je nachdem wie stark die Unterstützung ausfällt braucht es mehr oder weniger Strom.

I prefer using bike manually, without electric

Yes I knew that their power consumption was low but I really don't know how safe it is for kids.

Ich muss mehr über dein Bike schmunzeln, als über den Beitrag. Kannst du mit dem Bike richtig fahren, ich meine weite Strecken?

Ich habe immer noch mein gutes altes KTM Mountainbike, 21 Gang, Rapidfire Schaltsystem von Shimano usw. Fahre leider zu enig und bräuchte da mehr Antrieb meiner eigenen Batterien ...

... finde es grundsätzlich super, dass das Bike sowenig Energie benötigt :)

Das E-Bike ist besser als gedacht, eigentlich ziemlich bequem, und dank Motor kann man damit auch weitere Strecken fahren als mit einem normalen Bike. Bin positiv überrascht, dass es so wenig Strom benötigt :)

Electric bikes are fantastic for city riding, but for less rural places an electric bike can ruin the experience in my opinion

I think it's good to have the pedal factor still there, I mean health is a big concern nowadays and people really need to move their bodies more.

Don't say that about NOT pedaling hahaha, pedaling is exercising and I knew the energy of electric bicycles, but personally I prefer the conventional one.
I wish you a happy day

I didn’t realize e-bikes use so little energy. Makes me rethink my transportation options🤔🤔🤔, especially with such a low consumption rate too wow

I didn't know that an electric bike consumes so little energy. When I get tired of walking, I will buy myself an electric bike or electric scooter.

really? i didnt know that. it means e-bikes is really efficient.

0.00277270 BEE

The electric bike is not a bad idea though I'm still very fit and comfortable in walking with my two legs

I was thinking that electric bikes were going to consume so much electricity

But how do you recharge the electricity on the e-bike?

0.00275840 BEE

You can detach the battery and charge it at home.

Ehrlich gesagt hätte ich da auch keine Ahnung gehabt. Muss es bei meinem vielleicht auch mal messen.

0.00273280 BEE

hmmmm, that's way efficient! 🤔💪😎👊

Cooler Artikel. Ich wollt mir sogar n 3 wheeler electro bike hier in Thailand holen. Sowas gibts ohne Führerschein bei uns gar net. Muss ich ausprobieren und wenn es eventuell noch sparsamer und effizienter ist. Nice. Hatte mir auch eine solar power station bestellt. Wollt noch versuchen hier solar plus electro zu kombinieren. Dir einen schönen Tag mein Bester. Baba

Sowas kommt mir nicht ins haus, sonst bewege ich mich noch weniger. 😛

I expected them to take more power so I think it's nice to hear that they don't require alot of power.

Consuming that amount of energy, hope it is not really dangerous or what do you think?
