I don't see any place where they tell you the watt hours on the battery. That's really important as it will provide you a better sense of honest range. Figure about 20 wh per mile. also, it is 50 pounds. If you already have a bike you're riding you like, you might be able to come in at a lower weight with a simple add-on kit (check Leeds e bike kits and Dillinger kits for front 250w) for no more money, maybe less. If your hills are anything other than mild uphill slopes, a 250w motor on a 50 pound bike is going to heat up like crazy and maybe you will kill it. Bare minimum for hills is 350w, with 500w or better OR a mid-drive unit ideal. I had a 45 pound 250w e bike for a while and it was only capable of getting up very very short steep hills (equivalent to one city block) with me mashing in the highest gear like a crazy person. I would suggest getting a kit with more power rather than a heavy underpowered e-bike. Just my 2 cents.
Dillinger has this one on special - https://dillengerelectricbikes.com/e...dillenger.html - and even if you paid for bike shop install, you would come out ahead with more power and range.
