It must be excellent for you to live in the "land of liberty" where someone has to tell you what you should enjoy legally riding. At least in British Columbia, ebikes are fully legal on MUPs. With a speed limit of 20mph. A 250lb lycra doing 25mph on a MUP isn't very courteous either. I see them every day. What's the point of legislating all this if it simply up to a judge to determine that the rider wasn't riding in a safe and respectful manner. Its just common sense.

By the way, you are incorrect. Where did you get your information? This from the California Dept of Highways.
V C Section 21209 Motor Vehicles and Motorized Bicycles in Bicycle Lanes

Motor Vehicles and Motorized Bicycles in Bicycle Lanes

21209. (a) No person shall drive a motor vehicle in a bicycle lane established on a roadway pursuant to Section 21207 except as follows:
(1) To park where parking is permitted.
(2) To enter or leave the roadway.
(3) To prepare for a turn within a distance of 200 feet from the intersection.
(b) This section does not prohibit the use of a motorized bicycle in a bicycle lane, pursuant to Section 21207.5, at a speed no greater than is reasonable or prudent, having due regard for visibility, traffic conditions, and the condition of the roadway surface of the bicycle lane, and in a manner which does not endanger the safety of bicyclists.

Amended Ch. 262, Stats. 1988. Effective January 1, 1989.

This is an excellent piece of legislation, leaving it to the discretion of the judge and the rider.

I suppose a trike isn't a bike either though, no doubt the Handicapper General will report me.
