Steve I.wrote a review of Wahoo Fitness ELEMNT BOLT GPS Bike Computer Bundle on May 9, 2019
I've used the bundle for 14 months so that's a little over 10,000 miles.
HR monitor works as expected and so does the BlueTooth cadence sensor.
Unfortunately, 2 months after the warranty period expired.......so did the Speed Sensor. Fresh battery. Never been ridden in the rain. Impossible to receive impact damage because it's mounted on the hub body interior to the spokes. It just died. In 14 months.
The replacement is pretty pricey for what it does so I may go without.
