BMZ e-bike battery repair

BMZ Logo

Is your BMZ battery losing power? We'll get it back on track.

The battery manufacturer BMZ produced the batteries for the Go SwissDrive system. Many well-known brands such as Bulls GreenMover, Tour de Suisse, Radrezept , and Santos used these batteries.

They are known for their longevity, but even here the cells deteriorate after a few years.

Cell replacement & capacity increase

We replace the old cell packs. We often use more modern cells to increase the range of your e-bike.

Solving BMZ battery problems

We repair electronic faults and replace defective components.

Diagnostics & Software

We read the system data and perform capacity tests under real load conditions.

Dead battery fix

If your battery no longer charges after winter, we will try to reactivate the system.

E-bike battery repair: How we get your bike back on the road

1. Describe the problem

Simply fill out our form and describe what is wrong with your battery.

You don't have to decide on a service yet—we'll take a look at it.

You will receive a confirmation with all further information.

2. Bring or send the battery to us

Since batteries are considered hazardous goods, you have two options:
In person: Bring your battery (and charger!) directly to us in Rapperswil. This is the safest option and does not cost you any postage.
Shipping: Swiss Post does not transport used lithium batteries. Please use a private logistics service provider and pack the battery well-padded in a sturdy cardboard box.

3. Diagnosis & Repair

Our specialists will thoroughly examine your battery.

Only after the diagnosis do we decide together which repair (e.g., cell replacement or electronics check) really makes sense.

4. Full speed ahead

Once everything has been checked and tested, you can pick up your battery from us again or we can arrange for it to be returned to you by a specialist shipping company.
