And then I can completely let off the throttle to put my legs back to work on the flats, downhills, and lesser hills. Today was my first 14 mile commute to work, with 800' of ascent, I still showed up a sweaty mess, but my knees weren't blown out from the hills, what a great feeling. Now I'm just hoping there's enough left in the battery to get me home. On a test ride this weekend I was able to maintain 21.5 mph on the flats going directly into a 15 mph stiff headwind, and that's with me putting in a lot effort. I also find the throttle handy when starting off from a dead stop at a crosswalk, I think that's where I was putting in too much power to get moving quickly, and sometimes in too high of a gear, now the Hilltopper handles that for me. I was reluctant, but I'm so glad I made the purchase.
