Video quality is very good; other videos should be this good. I don't like choice of music; it is not my taste.
But riding engined bicycles on a public path designated for only people and people-powered-bicycles is illegal in all states. You're not stealthy, you are flaunting your presence to everyone who has a cell phone about to call the police with a complaint. Then the police are forced (against their will) to crack down on these engined bicycles, regardless of who is riding. Everyone gets upset.
Ride only the streets and at least obey street laws. There is no way you are stealthy when breaking posted laws.
Your concern is duly noted, and appreciated. Other than thinking I was braking the law, did you see anything else in this video that looked objectionable?
In Texas MBs are only subject to the same laws as any bicycle. No laws were broken in the making of this video, because in Texas MBs aren't considered motor vehicles.
All the bicycles I saw were going faster than I was. Some people don't even like that any bicycles are allowed on the trails, and think they should only be for walking and jogging.
The way I see it is if my tax $$ paid for the trail. I have a right to ride if I do so responsibly.
