I purchased the cheapest ebike for a friend who was visiting. Well, they did not use it and I was stuck with it. The frame is solid steel and heavy, the brakes were dismal and had to change pads and cables. The gearing is for flats and I'm in hill country. The wheels are wobbly under my 220lbs.The display is as reliable as a $2 watch, but....
I use it for simple commutes, It works and there is enough power and battery to keep me moving. I do not care if it gets stolen.
Of course I only use it for short distances.
