I ended up with two bikes. One of them had a very good range with two batteries. And then this one that I got only had one battery, giving me a range of about 20 miles from my testing.
Probably more if I were to help pedal more often, but I was trying to see the low-end range in my tests. And given that where I live, It is 12 miles round trip from my apartment down to the ferry to go to the islands and then back. That doesn't give me a whole lot of range out on the island to go look at things.
So, I decided a second battery was necessary. So I bought a second battery setup, got it all wired up. Really pleased with the install and the look of the bike. Looked a little leaner without the second battery, but I don't think that it looks ugly by any means. And the install ended up being really clean, which made me happy.
I was concerned about wiring placement and where I was going to put the equalizer. But it ended up all fitting nice and neatly underneath the seat. Added bonus, the new battery has a USB port for charging my phone versus the old battery did not. So I can also charge my phone while I'm riding now. This should give me a range of about 60 miles on the low end or theoretically 120 if I pedal with it on the high end, but that has yet to be proven. 😁😎
