True! On the way home (about 7KM/5M), I am biking mostly uphill which is sometime very steep. When you are taking that kind of path, and dropping speed can be even deadlier! :-)

Thanks for all the suggestions. I checked ebikes.ca. They seem to now only sell nine continent and Ezee motors now, although many of their info still is based on crystalyte! They have great prices on 2806 and 2807 models. Are these 400W-500W motors? Do you think is worth it to upgrade their 25A controller to a 40A one?
Their batteries also seems to be out of my range. I also cannot figure out how much Ah I need! Would 36V/48V, 8Ah run this motor for a decent range? Would I better off trying to buy a cheaper battery from ebay, etc? I know the danger with it, but I have read good things about ping batteries, and they seem to be cheaper (there are of course much cheaper LiFePO4 out there, but I guess you get what you pay for!)
