'Page has horizontal scroll which I can't get rid of

Please see https://simplybikestuff-staging-com.stackstaging.com/ I've gone through front page and removed code snippets to try get to the issue, but still no - I cannot get rid of the horizontal scrollbar.

The theme is using Sydney theme, with Bootstrap.

wordpress bootstrap-4

I'm very sure there is something wrong with the footer section (see the attachment below).

These images are also problematic because of undefined height or width.

You have to take a closer look and spend time on the footer to get your problem resolved.
