    If conservation of energy is the point of this quoted comment, why be concerned about the difference between bike and ebike riders (50#x16mph=800) and suggest the solution is to mix e-bikers up with...

    Here's my vote for the next Tyson's project: Fix it so the nice bridge over the toll road doesn't end at a really poorly implemented trail around the hotel to Spring Hill road. This path is...

    I should add that to get to 25 mph on the flats requires a lot more power--almost twice that at 20mph. One can reduce the load by reducing wind resistance via tucking, drafting and reducing rolling...

    It isn't fair to post a video in youtube with false information (e.g. that the ELF's top speed is 35mph when it is actual 20-25mph) and when corrective information is pointed out in the comments the...

    What consensus is there for limits on visibility markings? I run lights during the day and some cyclists cover their eyes in some sort of "your blinding me" pantomime. When I stopped using lights...

    Can you explain your reasoning? If I pass someone who is biking aggressively in my lane and there is a small amount of contact I would focus on maintaining direction and control. Looking back isn't...

    That's what I'd do as well. Round every geo-point to 1 decimal place. Most of the metro area riders would be in the 36 geo blocks between (38.6,-78.4) and 39.2,-76.8). Each of the blocks would be...

    "Considerate of others" is so corrupted by bias that it can't be a rational rule. Do we have to be considerate of people who hate purple and not buy a purple vehicle? The only rules that matter are...

    One point rarely discussed is the stopping distance. E-bikes are heavier but generally have front and rear disk brakes. On the downhill they go about the same speed as a traditional commuter bike. ...

    Average speed and level cruising speed are not the same.
    A 28mph level cruising speed is an average speed of about 19mph.
    The rest of your point isn't valid because your data is bogus.
