With the Heinzmann Direct Drive 500 watt hub motor using my own parameters for the programmed controller & a 1/2 kw hour battery on a bike weighing 60# including motor & battery along with a 200# rider in slightly better than average condition for a total of 118 Kg:
Minimal assist is about 166 watts of assistance & using mostly that I was able to ride more than 40 miles over varried terrain & over 50 miles of slight mostly uphill, my legs gave out before the bike & battery.
Medium assistance is a little more than 1/2 the power of the motor & with some regeneration on the downhills I found I can get about 30 miles out of the battery using mostly medium assist & some regeneration.
I expect that tomorrow I will get 20 miles using maximum assistance & little to no regeneration.
The next big test is up & down a mountain that is generally more than a 12% grade. The procyclist record is climbing it in less than 40 minutes but, no one has done the 6.6 miles in under 30, even in my car driving it every day for work I don't think I ever made the bottom to the top in under 20 minutes.
The ride totals for today include:
2.18 Kw generated by me to the 500 w provided by the motor
30.5 miles at an average of nearly 18 mph & top speed of 31
The ride took 1:42:49
I believe my total regeneration into the battery may have equaled 1/6 the battery.
Sometime this Autumn I hope to make 100 miles on flat land at the beach... we shall see, I will be in far better condition by then & another 15# lighter with as much weight as I can stripped off the bike.
