iGPSport BiNavi

The iGPSport BiNavi is a cycling computer with mixed reviews. Users praise its hardware: large readable screen, responsive touch interface, fast GPS lock, and good battery life (around 20-35 hours). It's lightweight and has a user-friendly UI. However, significant software issues exist, particularly with ANT+ integration: 'sticky watts' (power readings persist after stopping pedaling), inability to show battery status for third-party ANT+ sensors, and poor compatibility with some devices like Magene lights. Other drawbacks include no Strava Live Segments, unreliable phone app connection, and limited Di2 integration. Many users feel it's not yet ready to compete with Garmin or Wahoo, despite its attractive form factor and lower price.

How does it work with bike radars?

Works well with radars but not configurable. Beeps when first car is detected, double beep for fast approaching cars, and beeps when no more cars are detected after a long period.

What is the battery life?

Claimed 35 hours (BiNavi) vs 50+ hours (IGS800). Real-world usage reports around 20+ hours depending on settings.

How is the Di2 integration?

Limited. Shows gear position but not ratio, no tones at gear range ends, and only shows system battery level (not individual shifter batteries).
