eBike Battery Security in 2025: Smarter, Safer, More Connected
eBike technology continues to evolve, and nowhere is that more evident than in how we protect the most expensive component on an eBike—the battery.
Bosch has set a new standard in battery security with the introduction of Battery Lock – a digital feature that disables a battery if it's removed from its original eBike, dramatically reducing its resale value and long-term appeal to thieves. When paired with physical solutions like Katt’Fix, riders benefit from smarter, more secure protection—without compromising on convenience or ride quality.
Introducing Battery Lock – Digital Protection, Built In
Battery Lock is Bosch’s latest innovation in battery protection, available via the Bosch eBike Flow app with a Flow+ subscription. It digitally pairs your battery to your eBike, meaning if it’s ever removed, it won’t work on any other Bosch bike.
It’s simple, seamless, and gives you another layer of reassurance when locking up in public.
Critically, if you own a Bosch Smart System eBike, this will be able to be retro-added to your bike.
How It Works
- Digital pairing – Battery is electronically linked to your eBike
- Auto-locking – Engages when you turn off your bike or remove the display
- Multiple key options – Use the Flow app, or Bosch Kiox 300/500 displays
- Battery sharing – Can be temporarily disabled via the app if needed
- Works with DualBattery systems – Protection for all configurations
- Future-proofed – Remote battery locking is coming soon
Battery Lock joins eBike Lock and eBike Alarm in Bosch’s smart security ecosystem, offering a robust, connected approach to eBike protection.
Battery Safety: Bosch Leads by Example
In recent years, battery fires linked to poorly manufactured eBikes and non-certified chargers have made headlines—but it’s important to separate the facts.
Bosch eBike batteries are among the safest on the market, meeting the UL 2849 certification for electrical safety and adhering to the EN 15194 European standard for eBike systems. Each battery undergoes rigorous testing for impact resistance, overcharging, deep discharge, and extreme temperatures.
Bosch also offers full traceability, serialised battery data, and comprehensive diagnostics—something many lower-cost or grey market battery brands simply cannot match.
When it comes to safety, Bosch doesn’t cut corners—and neither do we.

Full Protection with Bosch Flow+
Battery Lock is part of Bosch’s expanding Flow+ suite, which includes:
- eBike Lock – Prevents motor activation without your app or paired display
- eBike Alarm – Sends alerts and enables GPS tracking if your eBike is moved or tampered with
- Battery Lock – Deactivates your battery if removed from your bike
Together, they offer smart, layered protection that works quietly in the background—so you can ride with confidence.
Launching Summer 2025
Battery Lock will officially roll out following its debut at CES 2025, and will be available via the Bosch eBike Flow app from summer 2025. It’s included in the Flow+ subscription, priced at £4.99/month or £39.99/year.
Extra Peace of Mind with Katt’Fix
To add a physical layer of defence, we recommend Katt’Fix—a stainless steel clamp that reinforces your battery’s connection to the frame. It's a discreet, tamper-resistant add-on that works hand-in-hand with Bosch’s digital features, especially useful in high-footfall or high-risk areas.
Final Word: Smarter Security, Safer Riding
Battery Lock marks a significant step forward in eBike ownership—giving riders the confidence to park up, knowing their battery is digitally protected.
Combine Bosch’s smart system with certified safety standards and physical deterrents like Katt’Fix, and you’ve got one of the most secure eBike setups available today.
