Thanks Zeacon and Brad. I have checked out the Zen Bikes. They seem to have only two models, Samurai (too expensive for me) and the Saral. The specs left me a bit confused, when I try to compare the bikes to other brands, such as, the Rize Leisure, for example. The main drawback for me is the pedal assist only motor, as I am 78 with bad knees who is looking at throttle biking. Thanks for your input
