I am 6'6" tall and weigh 225 lbs and I am looking for a powerful e-bike in the $2000 range. It must have enough power to get me up hills, a big enough battery to allow me to go at least 20-25 miles and the battery must be low, preferably built into the frame. I have narrowed my search to the three mentioned in the title based on research and looking at specs. I have never owned an e-bike so I don't know anything about the manufacturers and their reputation and reliability. Couldn't find any reviews on these yet. Can anyone give me some advice on the best way to select the one to buy or suggest a better alternative?
