I have the bolt and wouldn’t hesitate to recommend it. To answer your questions/points of interest directly:

1. If distance is the most important thing for you I’d recommend getting the speed sensor that goes on your rear hub as the package deal, which should only be a modest increase in price. While the head unit alone will do the trick, from my understanding of how GPS units work the head unit will measure your path, but occasionally check with the speed sensor to address any gps drift that may occur over time and therefore maintain the highest accuracy, especially in areas of poor gps coverage such as tunnels or forested areas. I might be very wrong on this though, and would happily be corrected.

2. Strava beacon doesn’t work with wahoo, however the wahoo app does provide a link which can be shared, so anyone you send it to can view your current location and track. You can choose to make it a permanent link so it never changes, or have it expire within a certain timeframe. It works very well.

3. I’ve never had the bolt drop a ride, however once (very soon after a firmware update) I did have the unit restart during a ride. I waited by the side of the road for it to restart, and it was able to recover and resume my ride without loss of data.

​​​​​​​Hope this helps
