Protectly GPS Tracker Extreme

In a market where bike theft trackers cluster at two extremes — cheap Bluetooth tags without GPS and pricey subscription models at €4-8 per month — the Protectly GPS Tracker Extreme attempts a third path: buy once, use for ten years. The built-in multi-carrier SIM is pre-activated with a data package that transmits locations for a decade, with no subscription ever required. At €90, compared to the total cost of a Vodafone Curve over five years (€40 + 60 × €3 = €220), that is aggressively priced. The specs are serious. Real GPS with cell-tower fallback, 4G LTE-M data, coverage in 150 countries, and a standby battery of up to 2,160 hours (90 days) — in live-tracking mode that drops to a few days, but in a normal 'one update per hour' mode you easily hit weeks. That makes the Extreme great for e-bikes parked in a shed all winter, or holiday bikes that see little charging during a camping summer. Compared with the Invoxia Bike Tracker (another popular Dutch option): Invoxia uses LoRa and Sigfox, which shines in France but is patchier in the Netherlands — the Protectly falls back on standard 4G, which is more reliable in Flevoland or Drenthe.

The big downside is size. At 80 × 40 × 20 mm the Extreme is not an AirTag; it will not fit inside a bike bell. Stealth mounting takes creativity: taping it under a bottle cage, sliding it into a hollow carbon seat post, or hiding it in an R2B-style accessory. For cargo bikes and speed pedelecs that is fine since there is more hiding space; for a trim folding bike it is trickier. The weight (about 90 grams) is also felt on a lightweight road bike.

The honest caveat: despite its technical maturity, the Protectly Extreme, like most 4G competitors, lacks Kiwa SCM certification. If ENRA, Kingpolis, ANWB or Centraal Beheer requires an SCM-certified tracker for your e-bike (common for Stromer, Riese & Müller or premium Gazelle), you still need a Tracefy MH or Biketrac. For everything below that — city bikes, mid-range e-bikes, cargo bikes, and even holiday bikes on tour — this is one of the best value propositions on the Dutch market.
