About this item

Geeko-Rear: A Cyclist’s Dream Come True! Whether for daily urban rides, epic long-distance treks, or tough mountain biking, it’s your perfect companion.

Fits any bike, be it 135/130MM quick-release or 148/142MM thru-axles. You can pick 250W, 350W, or 500W motors and match with 5.2-20AH batteries.

Smart drivetrain with a patented sensor tracks cadence and gears in real-time. High-efficiency motor provides adaptive power.

The 3-in-1 battery/controller/display, in a water-bottle shape, keeps your bike sleek. Modular design ensures mechanical performance, IP67 waterproofing, and data-based power management for reliable rides in all conditions.

Geeko Rear Motor

  • Lightweight & High-Torque: 2.8KG, 4.33 gear ratio, 40NM (350W) torque—quiet, durable power for tough rides.
  • Shimano HG Freehub: Excellent compatibility for 11-speed and lower cassettes. For 12-speed systems: Shimano MS or SRAM XD cassettes require replacement with a Shimano HG cassette.
  • Clutch-Enabled Free Pedaling: Built-in clutch eliminates magnetic resistance—pedal smoothly even when the battery runs out, just like a regular bike.
  • True 135MM Compatibility: 138MM dropout (250W/350W, 7-10S motor) truly fits standard 135MM frames—rivals claim 135MM but use 144MM.

Patented Cassette Sensor

The cassette sensor is integrated into the motor, eliminating the need for a bottom bracket cadence sensor(Such sensors are prone to failure).

The smart cassette sensor accurately captures real-time variations in pedal cadence and gear ratio. Combined with 100G’s proprietary, well-matched bionic power-assist algorithm, it enables real-time, precise motor control for a highly natural and seamless power delivery(The cadence sensor has no way to detect the gear ratio).

Bionic torque power, an electric power distribution and control system independently developed by 100G, closely approximates traditional torque-assist systems by offering cyclists a human-like, fluid riding experience that significantly enhances comfort and efficiency.

  • Linear, natural assist power ideal for multi-gear bikes
  • Each level achieves maximum speed
  • Levels differ by motor boost power (vs. speed in other systems)
  • Independent max speed/current settings per level
  • Auto uphill enhancement increases power on inclines
  • 50% longer range: 130km (10Ah) / 200km (15Ah)

Geeko Bottle

  • 6 Bottles x 4 Colors
  • IPX7 Waterproof Level
  • 3 Points Fixation: Battery firmly secured as a rock

*Mini and Solid do not have Part 02(PVC rubber band)

Intelligent Display

Featuring a bottle cap-integrated design with built-in Bluetooth 5.0, this display combines a 3-button interface and 1.25-inch digital screen for classic electric bicycle HMI, offering IPX7 waterproof protection (full battery bottle immersion resistance) and low-power operation (standby current ≤12mA).

Real-Time Monitoring

  • Battery level (1% precision)
  • Assist level
  • Controller connectivity (plug-and-play supported)
  • APP Bluetooth status (OTA updates enabled)
  • Flashing error code for fault Diagnosis

Operation Controls

APP

Key functions include:

  • Monitor speed, battery level, and ride stats in real time
  • Adjust assist levels (0-5) and modify settings
  • Fault diagnosis
  • OTA firmware updates

Controller

The controller is enclosed in an aluminum housing with integrated heat dissipation fins at the bracket base, ensuring efficient heat dissipation. Adaptive thermal management reduces power output incrementally under high-temperature conditions to prevent overheating.

  • Overheat Protection: Maintains safe operating temperatures for long-term performance
  • IPX7 Waterproofing: Fully potted with thermally conductive epoxy for submersible protection (1m depth, 30-minute immersion)
  • All-Weather Operation: Ensures reliable functionality in rain, mud, or extreme humidity
