Why Choose Gemstone™ Bike?
Unrivalled 6-Year Power Lifecycle
Protect your ride for up to 6 full years on a single power cycle (based on 1 position per day) without charging cables or routine maintenance. When the battery eventually runs low, you can easily swap the pack yourself at home. Note: Higher tracking frequencies will consume battery faster.
Global 4G Coverage & Lifetime SIM
Includes a pre-activated, lifetime SIM card operating on 4G LTE-M and NB-IoT networks. Track your e-bike, cargo bike, or road bike across 150+ countries right out of the box with zero monthly fees.
Intelligent Hybrid Positioning
Bicycles are frequently targeted in underground parking, communal bike sheds, or apartment basements where satellite signals struggle. Gemstone™ Bike uses WiFi-sniffing to scan nearby access points and pinpoint your bike's location indoors. Note: Indoor tracking requires an optional Premium subscription.
