I replace the first chain after about 1200 miles using chain lube. Then I started waxing the chain and the chain lasted almost 2 times longer and after about 4000 miles the chain ring and cassette are still in good shape. I make my own chain wax out of wax and cooking oil.
My ep8 motor would turn it self off , I found a loose wire from the motor to the display at the motor being loose. I plug it back in with a little silcone sealant around it to hold it in ln place. After about 4 hours ( to let the silcone set ) I went for a 11 mile ride with no problems. Hope...
