You may want to consider a bike that is approachable, easier to get on and off and easier for balance, like a step through or a bike with 20 tires. I have heard mid drives are smoother to pedal but they are out of my price range and most do not have a throttle. Someone posted info about Ariel C - mid drive, step through frame, nice specs. It was about $. 1700. I think the
ride1up 500 step through is nice ($1200)(hub motor). They also offer the slightly cheaper and lighter Core5 without a suspension fork. Another nice affordable step through is the Espin Flow. I have heard some older people like the Electric XP, easy to get on and off, sturdy, 4 inch tires, goes up to 28, throttle, shimano shifters, disk brakes. It folds. Decent battery. No suspension but some people add a suspension seat post. Comes assembled. It is only $ 899. I have heard that have a vet discount. I am sure some people will scoff that they are cheap bikes but the people that have them seem to like them. Speed seems easily controlled. Comes with rack, fenders and lights. The Rad runner is also a popular inexpensive 20 inch tire bike. Under $1000, and they also have discounts. I think it is heavy 60-65 lbs.
