Between ground and tires and between brake pads and moving surface.
It is helpful when you stop it helps you from falling if we didn't have friction we would keep going and if you wanted to stop you couldn't,explain, we'll say your riding you bike and there is a car backing up and you can't stop well that's why we need friction so we can stop fast and quick
i think you need the most friction in your feet and handsIt's hard to say where you'd need the mostfriction, as riding a bike requires several thingsto work together. And in each of those places you need enough friction.-you can't ride if tires will slip too badly on the ride surface-you can't ride if tires will slip too badly on the rims-you can't ride if wheels won't stay in the frame/fork-you can't ride if you can't stay on the bike
Muscles are what makes your body move, whatever you do. So you need them for bike riding too.
Friction can be both harmful and helpful. Without friction the tires of the bike could not push against the ground to move forward, and the brakes would not stop the bike. However, friction can cause parts of the bike and the tires to wear down. Also, to overcome the friction between the tires and the road you need to pedal harder to go faster.friction is helpful to stop the bike when you put on the brakes but it may be harmful by slowing your speed down. and if you hit the brakes hard at a sudden moment, you could tumble or flip

Most likely you would need to get a note from your Doctor excusing you from bike riding. Check with your specific school policy for the current rules.
We Increase Friction when we are stopping a car, bike or when slowing down to a way up.
Well yes, I you're riding a motorcycle. You even need a bike helmet when riding a bike. Seatbelts in cars, etc.
I am riding on bike since 1996.
Exercise as a rule is good, and bike riding is a fairly mild exercise form - but you need to consult your doctor.
well its the same question as why would you need balance to ride a bike. because if you dont have balance you wont get very far.
when you are riding it lol, jk, when you dont need it
