You might fall and get run over, or you might not be spotted and run over, you might slip on an oil slick, road debris, grating or whatever and get hurt.
Something on th bike might fail and cause you to go off the road, hit something or just take a tumble.
If you are thinking of cycling then never cycle on the path. Average bicycles will travel at about 20mp/h, and if you are travelling at such a speed on a pedestrians pathway and you hit one of them then they could get seriously injured and so could you. So cycling on the road is actually far safer. Unless the people driving around you are idiots.
You can fall off and hurt yourself that way. You can fall off and be run over by other riders or cars, if you're riding in traffic. If you ride in an improper manner, or ramp up your training too fast you can hurt yourself through overexertion. If your bike is't set up properly you can in extreme cases cause yourself nerve damage. If you ride in traffic other vehicles can simply collide with you.
You might fall, either from simply not being skilled enough for the kind of riding you do, or because of some unforeseen obstacle like a slippery patch.
Or another road user might bump into you. Either because you do something unpredictable, or because the other guy isn't paying attention.
Or you might hit another road user, either by wobbling or failing to brake soon enough.
If the weather is warm, you might dehydrate and/or suffer a heatstroke.
If the weather and/or your clothing is poor, you might suffer hypothermia, maybe even frostbite.
Important parts of your bike might fail. Either by poor upkeep, user error or random failures.
You could get knocked over, ride into a bollard, run someone else over.

The person who is riding the bike dies...if you hit him/her hard enough.
Not after riding a bike, but rather during riding a bike. Your muscles convert chemical energy (a form of potential energy) into mechanical energy to do work.
Muscles are what makes your body move, whatever you do. So you need them for bike riding too.
Riding a horse can be compared to riding a bike. if you do not have balance, you can throw the horse (or bike) off balance and/or slide off to one side.

Obesity will not only be stopped by riding a bike, but will be stopped by exercising in general and watching calorie intake.
Well, it'd really depend on how hard, for long and how often you ride. But bike riding can help shape and strengthen your legs.
