Thanks for the reply Nightdiver. Puerto Rico follows U.S. Federal law which allows a motor of up to 750 watts (1 h.p.), whose maximum speed on a paved level surface, when powered solely by such a motor while ridden by an operator who weighs 170 pounds, is less than 20 mph.” The federal law permits e-bikes to be powered by the motor alone (a “throttle-assist” e-bike), or by a combination of motor and human power (a “pedal-assist” e-bike).

I plan to focus on hub motors which are suitable for my limited budget. I am retired and have a limited income.
