Pros and cons
Invoxia Bike Tracker
Pros
- Genuine GPS plus 4G LTE-M network — works anywhere in Europe without iPhone density
- Three years of subscription included in the purchase price (saves around €120)
- Motion alert when the bike moves unexpectedly — no tip-off to the thief
- Up to six months of battery life with normal use, USB-C rechargeable
Cons
- Visible as a reflector — savvy thieves eventually recognise the form factor
- After three years you must renew a subscription (€3 to €5 per month)
Harbor Bikefinder AirTag Houder
Pros
- True stealth: unreachable without removing the bottle cage — ideal as a secondary line of defence
- Fits under virtually any bottle cage with standard M5 screw holes
- Black fibreglass-reinforced plastic — corrosion-resistant against Dutch rain
- No measurable interference with the AirTag signal in real-world tests
Cons
- If your bike has no bottle cage bosses (some classic city bikes), it will not fit
- AirTag sold separately — total investment around €50
