Before I made this run several times Collin did a evaluation on my motor compared to a Scott motor that Eric used on his bike.
In real world use I'm sure the figures Ciollin came up with are 5 to 10 % off but close!
I did make it all the way up on three 12 volt 33ah rated Evercel batteries.(the same power density as NIMH batteries) but after a 20 minute rest 1/8 mile from the top of the summit.Cilins guesstimate was 2.6 hours if I made it at all.That was about exactly right.My total time all the way up was 3 hours.= 48 watt hours per hour on the UP hill climb of 36 miles. The trip down hill at 35 mph+ speeds was already paid for comming out to a 20 mph avrage speed on the round trip at 24 watt hours per mile for the 72 mile trip in the most extream conditions.I still doubt it that the Scott motor would have made it 1/3 of the way up without over heating and sucking the life out of the batteries.
