I've been commuting by bike since 2009. I enjoy road cycling and occasional mountain biking.

comment Why would a bike computer calculate distance accurately but average speed inaccurately?
This answer does a fantastic job of explaining the limitations of processing in a bike computer. But I think there might be just a bit more to the average thing because the bike computer shows average speeds changing in 0.1 mph increments but the error is much higher than this. Is there maybe some way that it's using a lookup table to find the average speed in discrete time intervals and then it has some way of "cheating" to combine these?

@imel96 I've edited to mention that it's a non-GPS bike computer.

It does stop accumulating time at stops, but it also stops updating the average speed at stops. So as far as I can tell, the "trip time" and "avg speed" are supposed to be moving time and average moving speed.

comment Safe saddles for men's health
In general, requests for a list of products aren't a good fit for the site's format. Would you consider rephrasing to be more about what to look for in saddles?
