Q: How does the DIDI.BIKE Sensor measure aerodynamics?

The sensor calculates real-time CdA (coefficient of drag area) through 6-axis IMU integration at 100Hz. It continuously monitors torso angle (0°-45° range), pelvic rocking, and seated vs. standing position. According to cycling aerodynamics research (Blocken et al., 2018), optimizing riding position can save 15-20 watts at 40km/h — equivalent to a 30-second advantage over a 40km time trial.

Q: What platforms does the DIDI.BIKE Sensor integrate with?

The sensor broadcasts via ANT+ and Bluetooth LE 5.0, connecting directly to all major cycling computers and platforms — including Garmin, Wahoo, and Hammerhead head units, as well as Strava, TrainingPeaks, WKO5, Golden Cheetah, Wahoo SYSTM, and Intervals.icu. No proprietary app is required. A Developer API provides WebSocket streaming at 100Hz, REST endpoints, and SDK libraries for Python, JavaScript, and Java.

Q: How accurate is the DIDI.BIKE Sensor compared to motion capture?

The DIDI.BIKE Sensor achieves ±0.1° angular accuracy with 99.9% data retention and <5ms timing jitter. Setup takes under 30 seconds vs. 30-45 minutes for optical systems. It captures 600 data points per second (6-axis at 100Hz) compared to 240 points from 4-camera systems at 60fps. The key advantage is full outdoor support — traditional motion capture is limited to indoor labs only.

Q: How much does the DIDI.BIKE Sensor cost?

The DIDI.BIKE Sensor retails at $299 USD for individual riders. For bike fitting professionals, the Pro license is $499 and supports up to 8 simultaneous sensors with ±2mm accuracy. OEM bulk licensing for manufacturers starts at $180/unit for 1000+ units with $15-25/unit BOM cost, custom firmware integration, and 24/7 enterprise SLA. Enterprise API access is available at $299/month with unlimited data retention and 99.99% uptime SLA.

Question 1

What is the DIDI.BIKE Sensor?

Accepted Answer

The DIDI.BIKE Sensor is a 14-gram professional cycling telemetry device that measures aerodynamic drag (CdA), pedaling dynamics, and posture in real-time at 100Hz. It uses a 6-axis IMU (gyroscope ±2000°/s, accelerometer ±16g) with ±0.1° angular accuracy and <10ms latency. Priced at $299, it replaces traditional optical motion capture systems costing $15,000+ while supporting full outdoor use.
