Have you seen some of the new E-Bikes? They are awesome! Have had one for over 7 years and need an upgrade. Look at kick starter and search e-bike. Also search e-bike with Google. These types of bikes are a blast to ride, get you outdoors and give you some exercise.
I live in Colorado and we have so many great bike paths. These are permitted on all of them as long as you are respectful of the other riders. What does respectful mean? Well, try not to pass sweaty folks in bike shorts and colorful jerseys riding carbon framed bikes while wearing blue jeans and flip flops (and not peddling)! ha ha.
