Thanks BA. I consider this advise very valuable. Nothing you've said disagrees with my very limited experience so far.I'm no ebike expert & this is pretty basic stuff so you're prolly familiar, but I've both a basic commuter & a "busy" 21sp hybrid & it seems to me the most effective method of extending maximum range is twofold, being never exceed about 3/4 throttle & consistency - pick a speed & stick to it w/as little throttle movement as possible.
It's admittedly a safety issue so I can't actually recommend it, but I've found that setting the digital cruise control to 75-80% of my max potential speed (flat ground) on my ebike commuter and just leaving it alone works wonders, you'll not have this issue but when my speed drops to my available pedal speed range I just begin assisting to maintain - thereby reducing the maximum amp draw from my packs. I'm not as good without the CC but I'm learning to fake it pretty well w/the hybrid, I can sympathize with the busy gear thing on that'un... on the other hand it's great for maximizing efficiency in assorted conditions (hills, textured terrain, headwind, etc).
It's the "spikes" in usage that seem to hurt reserve the most, not just off the line or hills but even just for a sec to to regain from deviated cruise speed after a shift or w/e, add all those little over-corrections up over the duration of the trip and they could be a couple few miles of easy cruisin'... pretty much any time you can take the edge off throttle application & it's amp spike helps a ton, soft easy shifting & smooth cruising seems to be the way to get the farthest, not dissimilar to trying to get mileage out of a V8 w/a four barrel, don't let those secondaries open lol
Only real problem is not geeking out the ebike stuff so much I end up in the ditch
Since the first second, my throttle application has been very clumsy, and continues to be. It's going to take practice to become consistently smooth with the throttle. I'm still in the process of figuring out the best gear shifting technique, but it seems like there's not much point going below 7th gear. I can't shift fast enough the keep up till about 7 th. Anything below 5 th is to low for powered riding. This gearbox feels very wide ratio to me. There's a big difference from 7th to 9th.
Knowing how bad I'm riding right now, I'm pretty sure if I master your advise I can get to 45 miles per charge and above.
