• Distance (per trip and lifetime in miles or kilometers)
• Ride Timer (elapsed time in hours, minutes, and seconds)
• Compass (indicates N, NE, E, SW, S, SW, W, NW)
• Altimeter (indicates current altitude, total climb, and net altitude gain in feet or meters)
• Humidity (indicates 0 - 99%)
• Temperature (current temperature in degrees Fahrenheit or Celsius)
• Time & Date
• Cadence (the number of pedal strokes per minute)
• Total Calories Burned

6 easy-to-replace Energizer® Lithium AA batteries

Cables & Wiring:

All cables and wiring are internally routed for weather protection and to provide a sleeker, more elegant appearance

Lighting:*

Bright, high-efficiency LEDs are microprocessor controlled. Lighting system includes:

• Headlight - bright, white LEDs turn on automatically based on ambient lighting conditions to provide low or high lighting, lights also turn off automatically in bright conditions or after a period of inactivity (no bike motion)
• Taillight - red tinted taillight illuminates automatically along with the headlight and under braking (just like a car's brake lights)
• Turn Signals - Front (amber) and back (red) turn signals are activated by a handlebar mounted switch, integration with the Bigha's compass means the turn signals automatically turn off after a change of direction

Security:*

Upon activation, system emits a warning beep if bike is moved (the security system detects motion in any direction, the bike does not have to be rolling for the system to activate) — if movement persists, a 100-decibel alarm is emitted until the motion stops. Alarm is armed and disarmed using a small, cylindrical key included with the bike (each key carries a unique code).
