I think when the bike has constant speed the net force is 0 so it doesn't accelerate. If I cycle at constant speed and then stop cycling the bike will deaccelerate because of friction. If I want to keep it at constant speed I need to put in a force such that the horizontal net force is 0. If...

I don't understand how there can be no friction at constant speed. Must there not be a force that counteracts the friction that tries to stop the bike. If there is no friction then a bike at constant speed can go forever no?

So I have difficulty understanding this https://physics.stackexchange.com/questions/331173/why-is-friction-only-on-the-back-wheel With constant speed cycling uphill the front wheel has no friction. But if that would be the case how does the wheel even spin?
