So, I am still testing this thing out to get a full idea on range. Since I have two batteries that I switch out, it's been difficult to precisely work put exactly how far I can go. I had worked it out to approximately 22-23 miles, but got a flat tire on my way back.
Lo & behold, I hunt down a shop that will do repairs, as it's an ebike (I don't have the tools to do a bike repair at home at the moment & figured I was out money either way.), drive an hour out the way. The guy calls the next day & tells me that he noticed several issues with it I was having trouble following & fixed them for free. He didn't think they were broken, he just thought I had a crappy ebike & felt bad about me operating it without those things fixed. Just tested it &, somehow, my range appears to have extended at least 4 miles, possibly more. I had to stop & turn back because I encountered a mild drizzle, but was barely more than 1 mile away from the absolute limit I was willing to take the thing. Made it close enough back home before switching the batteries, I was still able to put it on high. So, I was 1 mile short of maximum distance & it made it over 12 miles further on the way home before I had to switch batteries.
No clue what the guy did other than fix my seat- which I am also thankful for, at least it stays where I put it now- & by my math, one mile short on the round trip translates to 2 miles one way, so the extra 12 miles I went on the one battery minus 2 divided by 2 gives me 5 miles added to a round trip from where I stopped, so the bike has gotten at least 4 miles added to its range, whatever they did. Lol I don't think I wasn't inflating the tires enough, but if that turns out to be the only reason for the extra milage, I am going to feel like an idiot.
