Good questions. I have the stock Amped bike front hub motor with the stock Li battery in their ad. The kit sells for something like $800. There are two buttons, one on the battery tube and the other on the handlebars. Both have to be on for the bike to go. When the bike stopped, the battery level lights went off and of course there was no power. I turned both buttons off, than at the top of the hill, I turned both back on, the lights came back on and everything was OK. There is nothing to read unless there is stuff on the controller inside a bag under the back of the seat....just the two buttons I mentioned, a thumb throttle, and 3 lights that show you it is on and the battery level...green amber, red. 750W, 36volt. Can you tell I didn't do the conversion? A bike shop did. The hill is steep, but I don't know the grade. My daughter who is 15 and weighs 110 lbs can ride any of the ebikes up it though with motor assist. I actually have ridden the two other ebikes up that hill myself but they don't sound too great. They do not have cutoffs on them though like the Amped bike apparently does. Anyway, I consider myself lucky I have not burned something up. I just walk the bikes up the hill now. It's all exercise anyway and that's why I ride the ebikes. If I want power and speed, I take my Zero S, Ninja 250, or Vespa 300. All three of those accelerate all the way up that hill. I didn't get any paperwork except some instr. about how to hook up the charger with the Amped Bike. It is a great system. The only thing is it goes so fast, that I find myself not pedaling much, hence no exercise, except for my hill of course. The other two bikes aren't as powerful and are slower, so I pedal more with those. Thanks for your replies.
