Classywalk s420 modified front shock

Only pick up no shipping.Front bar shaky because I modified with n7 front shock, it has 20amps battery so it can take you long distance. It has error 07 but still running 2 motors no problem even has error 07. The old front shock is broken you can fix it if you have welding machine. But I used n7 front shock so still usable still you can use it no problem.
