Kattfix Battery Lock — Riese & Müller Multicharger2

£169.00 GBP

Made to order in Münster, Germany, the Kattfix is laser-cut from hardened stainless steel around an ABUS locking core, and anchors the battery housing to the frame — once closed, the lock cannot be shifted. You can still remove the battery as normal to charge it. This one is made for the Riese & Müller Multicharger2.
Key specifications
  • Hardened stainless steel with an ABUS locking core, made in Münster, Germany
  • Lightweight — around 268g
  • Fitted with included adhesive strips; cannot be shifted once locked
  • The battery can still be removed as normal for charging
  • Slim 100mm profile; neoprene and foam-rubber linings protect battery and frame
  • Two keys included; repairable, recyclable construction
Compatibility

Made for the Riese & Müller Multicharger2 with the 750 Wh battery. The earlier Multicharger takes a different version, so the model name on the frame matters.

What's included

Kattfix lock made for this frame, with its adhesive strips included and two keys. A hidden compartment for an Apple AirTag is available on request.
Security rating

No Sold Secure rating — this is a deterrent layer for the battery itself, working alongside your main lock rather than replacing it. Your bike still needs a Sold Secure rated lock; the Kattfix protects the component a frame lock leaves exposed.

Worth knowing: some insurers now surcharge or exclude e-bike batteries from cover, which is exactly the gap a battery lock closes.
