Since may, I have the Engine X bike. Suddenly, the bike was not turning on, so I had no display neither pedal assist. Send an email to the support team and they promptly answered me. They were happy to help me sort out the cause and, once we found out the issue thanks to a step-by-step guide they sent me through email, they sent me the replacement parts over the mail. Assembling things was quite easy, since each electrical cable has one size and socket - they probably made this in order to make the bike as easy to repair as possible, and now everything works as intended.
