Hi @lightning , What chain model are you using? Did you de-grease the chain before it's first use? I've been using squirt wax lube on my recent ebike chains and have got a maximum of 1500 miles before passing 0.5% wear. Keep posting your updates!l bang through the gears without getting off the gas, tbh when accelerating on the road it's difficult not to because the E8000 runs on for a second after you back off pedalling
l've never had a rusty chain using GT-85 and l've ridden in torrential rain. l am getting towards 0.5 on my chain now, and will keep on with the test to see what happens.
