Without also requiring bikes to come with speedometers* I think this is absurd. The whole reason speed limits for motor vehicles is a reasonable concept (regardless of the speed limit itself being reasonable) is that all motor vehicles made since about 1910 have had them a speedometer. Of course you can tell if you're moving 30 MPH versus 15 MPH, but speeds marginally faster than 15 MPH just don't feel significantly faster. Without the ability to see your speed, and more importantly, the expectation that everyone on the trail can know their own speed accurately, this smells of an easy cash grab by law enforcement. I'm not even saying I think speeding on a bike on a mountain trail is safe or a good idea. I just think it's unfair to enforce something like this if your average person isn't going to be able to make sure they're complying like your average driver of a car can. If no one mountain bikes without a speedometer then I suppose my point is moot, but I'm not a mountain biker so I wouldn't know. *A quick search on Amazon reveals many for less than $20, but I've never seen a bike sold with one attached.

Smartphones with GPS can also help in ascertaining groundspeed. I would imagine it would make sense to only ticket those coming down bends and turns recklessly where they could easily barrel into a ped.

The whole reason speed limits for motor vehicles is a reasonable concept is that the majority of them weigh more than a ton. Applying similar logic to bicycles is asinine.

  People routinely break their own bones when mountain bike riding. There is plenty of momentum available to do serious damage. It's a shared trail. Would it be safe for hikers if someone rode a bike at 100mph? Of course not. To paraphrase Churchill, we've established the need for a speed limit, so the only thing left to discuss is which speed to set the limit at.

There are weight limits on many bridges yet pickup trucks are sold without a built in scale. Basically, if you think you might be breaking the law, it's up to you to figure it out. I ride very causally, and use an App to measure my ride. From that, I know I average around 10mph when riding with my spouse. It's not hard to extrapolate and figure out where the limit is.
