After purchasing the G660s model, e10 error occurred occasionally in the instrument panel for about 2 years. At first, it was only a short while, but after 3-4 years, the error did not disappear. After self-inspection, the cable was disconnected. If you pay $7, you will buy the cable, and if you add $7 for the damaged battery contact, you will send it, so I paid with the shipping fee and received the product a few days ago. Now, I'm riding well without any problems. When I bought a bicycle in 18, I worried a lot about as and purchased it, but since you care about self-repairing so cheaply, I think you did a good job of buying a bicycle here. Thank you again for giving

The part separated from the old one is different, but I am very satisfied. I am 3 years old, so it seems like it is old and new, but it seems like it has been upgraded. And I like it even more because the delivery is fast. I will ask for other parts in the future. Thank you.
