Electrically-assisted bicycles (EABs) have become commonplace, and it’s the battery that often accounts for the lion’s share of their value. Its importance is paramount, as it determines the performance and lifespan of your bike.

A VAE battery can last from 1 to over 5 years. That’s why it’s essential to choose the right battery for your needs and budget. Here are the two main approaches to purchasing a VAE.

Often sold for between €1,000 and €2,000, these bikes are an excellent option for beginners. Most models use 36 V batteries, with capacities ranging from 250 to 750 Wh (not kWh, which is a much larger unit). The watt-hour (Wh) is the most important value to consider, as it determines your bike’s autonomy.

On these models, the weak point is often the battery, which generally lasts 2 to 3 years. The good news is that it can be reconditioned! This involves replacing worn cells with new ones. It’s a more economical and environmentally-friendly solution than buying a new battery. The cost varies from €250 to €450, depending on the power and quality of the cells. To prolong the life of your battery, opt for better-quality cells during reconditioning.

These bikes, which sell for between €3,000 and €5,000, are often equipped with motors and batteries from well-known brands such as Bosch, renowned for their quality and reliability. Top-of-the-range batteries are designed to last longer.

However, a major drawback is that they are generally sealed for safety and warranty reasons. This makes them difficult, if not impossible, to repair. In the event of failure, they have to be completely replaced. The cost is considerably higher than that of a generic battery.

The choice of an electric bike depends on your budget and your needs. The lithium battery will inevitably need to be replaced or reconditioned over time. Plan on a budget of €400 to €700 for maintenance or replacement.

To repair, exchange or recycle your battery, you can call on specialized services. Here are your options:

• Repair/reconditioning: a cost-effective solution for extending the life of your battery.
• Standard exchange: you receive a reconditioned battery in exchange for your own.
• Recycling: a responsible option if your battery is out of use.
