Yes, yes, yes. The warranty is voided when you fit something like this. Isn't that kind of understood by all?
I'm working with Jum now to figure out what's best for my bike.
I rode it 23 miles home from work yesterday, at an average of 21.5 mph. I cleared 30 mph at least once, but mostly took it pretty easy to make sure the battery would last the whole way. The display still registered 2 miles of range left when I got home, despite a nasty headwind and 500' overall elevation gain. I left it on Sport mode until the last few miles, and then put it into Turbo once I knew I was really close to home.
