I don't think the recently passed law regarding the Mickelson Trail distinguished between E-bikes and E-trikes.  At least in my reading of the legislation, I couldn't find any difference. 
As long as your bike meets Class 1 restrictions, I think you'd be okay.
Class 1 is:
1. Maximum assisted speed 20 mph
2. Maximum motor power 750 watts, or less
3. Throttle not permitted
Class 2 and Class 3 e-bikes are not allowed since the new law was passed.
If I'm wrong about that, I hope someone will correct me.  Thanks.
