Kattfix Battery Lock — Tern HSD

Kattfix Battery Lock — Tern HSD

£169.00 GBP
Battery

Made to order in Münster, Germany, the Kattfix is laser-cut from hardened stainless steel around an ABUS locking core, and secures the battery to the frame while leaving normal battery removal available to you, so charging carries on as usual. The Tern version is built differently from the rest of the range: it clamps between frame and battery rather than fixing to the frame. This one is made for the Tern HSD.
Key specifications
  • Hardened stainless steel with an ABUS locking core, made in Münster, Germany
  • Clamp fitting developed specifically for the Tern — sits between frame and battery
  • The battery can still be removed as normal for charging
  • Slim 100mm profile; foam-rubber lining protects battery and frame
  • Two keys included; repairable, recyclable construction
  • The lock itself can be unlocked and removed by the owner — useful at the end of a lease
Compatibility

Made for the Tern HSD, in versions matched to the battery fitted — including the 545 Wh and 800 Wh smart batteries and the 400/500 Wh PowerPack. We confirm which battery your HSD carries and order the correct one.

What's included

Kattfix lock made for your HSD's battery, with 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.
