Review on 🚴 SHANREN Raptor II Pro: Wireless Bike Computer with Front Light, Odometer, Speed and Cadence Sensor – Rechargeable Cycling Companion for Most Bikes by Chris Peck

Cadence and speed sensor not working. The indicator light does not light up when held for the required 6 seconds, causing pairing to fail. The clock and wheel circumference are working, but because of this error you are not sure about anything else. I'll call support in the morning. Somewhat easy to attach parts to the bike. I didn't bother too much with the instructions in the manual, but Youtube came to the rescue. The headlight is very bright and has three settings. CONTINUED: I noticed that there was a clear acetate film between the battery and the sensor, so once removed the cadence/speed sensor works great. The instructions didn't mention removing this, so they should be updated. The sensor is accurate, but of course it is based on correctly entering the wheel circumference into the device. In terms of accuracy, it paired well with my Strava GPS. The display can also be read in sunlight and is well illuminated in the dark. So I am changing my rating to 5.
