Some bikes, I think children’s bikes or a certain type do. Usually the pedals will just spin backwards and make a neat sound, it won’t actually pedal in reverse. Bikes usually have brake levers on the handle bars that control brake pads on the front and back tires; right lever for back tire, left for front, in my experience.
The only bikes I can think of that will actually go backwards from pedaling backwards are toddler bikes like a tricycle or toy bikes. That might be why the image has him sitting backwards, because generally it’d either stop the bike or just spin the pedals doing nothing.
The title makes it sound like intrusive product ads when it’s just pictures of bundles for skins and other cosmetics that are currently available. Not nearly as bad as it could be ¯\_(ツ)_/¯
