About us

At KWS Seuren we focus entirely on testing, repairing, re-celling and developing e-bike batteries. We do this for private users, but above all for bike shops, insurers, care institutions and other business partners. Below we explain exactly what we do and how we work.

Every battery that comes in is tested thoroughly first. Among other things, we check:

• Capacity and cell balance

• Communication with the bike

• Whether the BMS works as it should

• Error codes and faults

For this we use test rigs set up for the brand, the type and the software version of the battery. Based on the diagnosis we draw up a concrete proposal for a repair or a cell replacement.

Is the battery worn out but technically still in good condition? Then we re-cell it. We replace the old cells with new A-grade lithium-ion cells that perform as well or better. The whole process follows the correct specifications for that battery.

• Complete replacement of the cell pack

• Original BMS retained (if it works properly)

• New thermal and mechanical protection

• Quality check with a final report

Sometimes it is not only the cell pack that is faulty, but the circuit board or BMS as well. For many battery types we can replace or repair these electronics. In other cases we develop our own circuit boards, which are 100% compatible with the original bike.

• A fix for error codes and indicators that no longer work

• Support for older battery types for which parts are no longer available

• Flexible solutions

For customers who need a replacement quickly, we also supply re-celled batteries from stock. They have been re-celled and tested, and come with new cells and a warranty.

• Available straight away

• Ready to use

• Sensibly priced

Our services are built around the day-to-day practice of bike shops and business clients. We help you work out:

• Lead time and capacity

• Service processes in the shop

• Insurance claim handling (as we do with ENRA)

• Custom solutions for mobility partners

Since 2025 we have been working from our new premises at Transportcentrum in Beugen. We have more space here and a modern workshop, plus safe storage for lithium batteries. It means we can keep re-celling, repairing and collecting (e-bike) batteries safely, to a higher standard and for years to come.

The basic facilities are finished and the workshop is now fully in use. Our team already works from the new building, while the fitting-out and furnishing of the offices and reception areas is still in full swing.

• A workshop with modern equipment for cell replacement and diagnosis

• More space and a better overview in logistics and assembly

• The rest of the building is being fitted out step by step

After months of development, KWS Seuren introduces these circuit boards, designed entirely in-house. Among other things, these electronics make it possible to repair and re-cell Van Raam batteries again, with the original functions intact.

In a new video recorded by Eric Peters, we take customers and partners through our whole process, from the moment a battery arrives to its final check. We show how we work, what we test for, and how safety and quality come first at every step.

KWS Seuren becomes preferred supplier for ENRA, one of the largest bicycle insurers in the Netherlands. Since then we have handled the repair and cell replacement of batteries that are reported through bike shops as damaged or faulty.

The building takes on its final shape.

Groundwork has started for the first phase

2024 is the year in which we rebuild our premises completely. The drawings are finished and the calculations are getting their final touches. We are ready to start.

Our service van lets us visit both existing and new customers, so we can extend our service and be more visible at the same time.

Many well-known brands and new e-bikes on show, with a test track for the various e-bikes at the fair. Good to see that the e-bike market is still growing strongly.

Presentation for Domino's Pizza

We were invited to give a presentation to a large group of franchisees of Domino's Pizza Netherlands about (faulty) delivery bike batteries, covering both the opportunities and the risks.

Trade fair for the two-wheeler sector in Gorinchem. Many of our business customers were at this fair.

MT/Sprout

MT/Sprout named KWS Seuren one of the 25 most promising under-25s of 2021.

A year later we were using the whole building.

At the start of 2020 we moved to a warehouse of more than 1,100 square metres in Beugen (municipality of Boxmeer). About 25 employees work together here every day from Monday to Saturday, on everything from battery repairs to complete cell replacements and diagnosis, mainly of e-bike batteries.

In 2019 we took on our first employee for repair and cell replacement work, because requests kept increasing and we already had a regular customer base by then. In the same year we became a recognised training company, so that we can offer work placements as well.

This year, alongside our studies, we were busy expanding our customer base for e-bike batteries, from business customers to consumers all over the Netherlands.

In 2017 we started actively repairing and re-celling all kinds of batteries. This was back when all three brothers were still studying. The workshop was in the attic at the back of the house.

With years of experience and our own development department, we have a solution for almost every e-bike battery, from well-known brands to specialist models. We re-cell, repair and test batteries from Giant, Bosch, Bafang, Flyer, Batavus, Sparta and Trek, among others, as well as less common systems and older types.

We also build custom batteries for use in mobility, care and industry: from adapted bikes and scooters to batteries for boats, lifting equipment, household appliances and tools. Even for batteries that others say are beyond saving, we often still find a solution.

Whatever is wrong with your battery, we will look at it with you and get you moving again.

KWS Seuren specialises in testing, repairing, re-celling and developing batteries for e-bikes, mobility aids and scooters, among other things. Our policy statement sets out how we deal with quality, customer satisfaction and continuous improvement in line with the ISO 9001 guidelines.
