I am a senior and I want to buy my first ebike. I live in a hilly area and need help getting up the hills but I don't want a bike that is so powerful it will have me zooming too fast on the flat bits. I prefer a foldable step thru bike as I live in the city and want to be able to take it on the train. As it is my first, I don't want to go crazy with price. I was hoping to find something acceptable under $1000 but I am afraid that the companies in this price point won't offer good customer service if there is a problem. I would love to hear from others who may have experienced customer service in this price point. Thank you for your time.
