E-Bike: How long does the battery of an electric bike last?

How long do the lithium batteries contained in our electric bikes last? Let's go and answer the question.

The life of a battery in an e-bike, a problem that for most users does not exist: if you use quality batteries and brands. Electric bicycles are equipped with lithium-ion batteries and, according to the manufacturers, there is talk of an average decline of 5% per year with a noticeable deterioration (around 50%) between 500 and 1000 complete charging cycles. A mileage estimate means between 20.000km and 30.000km. The range is so high because it depends a lot on the conditions in which the battery is held (and used): a battery used in Turbo mode deteriorates much sooner than a battery used in Eco. This should make you understand that the batteries, if they have no problems and are well maintained, have a very long life and let's go back to my first statement, namely “The life of a battery in an e-bike, a problem that doesn't exist”.

Often the average user worries too much about the life of a battery

Why do I say this? Let's say you do 2 rides a week where you consume 50% of the battery and recharge as soon as the ride is finished. So full charge cycles are 1 per week. In a year there are 52 weeks and therefore it means that in 5 years you will recharge your e-bike 260 times. In today's society, you will change 4 bikes before changing a battery because it is dead. Then if we go to evaluate the fact of a user who only goes out on Sunday we understand that it is a non-existent problem or, to be precise, non-existent if established brands are used and not batteries of dubious origin. All these speeches of mine concern a user who uses e-bikes for sporting / recreational use.

HOW TO CHARGE THE BATTERY OF AN E-BIKE

To understand how much a battery is “worn out”, especially on used bikes, contact the shopkeepers equipped with diagnostic tools for the specific brand of battery that we want to analyze.

ppgad@pucrs.br I am passionate about everything that has 2 wheels: in my youth I practiced competitive cycling on the road and on the track with good results. At the age of 18 I moved to cross country competing at national/international level as U23. Once I passed Elite, I made the choice to take things easier from the training point of view, and that's how my love for gravity disciplines was born, training as an FCI MTB instructor and guide. Now I have made my passion my profession by managing 3 MTB centers on the island of Elba (Elba MTB), creating the FANTAmtb and telling in an ironic but professional way, everything that revolves around MTB thanks to 365mountainbike and 365TV (YouTube 'PULITI dentro BIKER fuori').
