Pros and cons
Protectly GPS Tracker Extreme
Pros
- Ten years of data service included — no hidden monthly charges
- Standby battery up to 2,160 hours (90 days) — far longer than the Vodafone Curve
- Real 4G GPS across 150 countries — works in rural Netherlands and on holiday in Italy
- No anti-stalking limitation like the AirTag — thieves are not warned
Cons
- Larger and heavier than an AirTag or Chipolo — stealth mounting takes more creativity
- No Kiwa SCM certification — ENRA/Kingpolis will not grant premium discounts
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
