I am dumb so I need help with this

Say I have an electric motor that can put out 1492 watts of power (about 2 hp). If I put it on a small bicycle, how can I use this info to determine force, acceleration, velocity, etc..? Say the bike with a person on it weighs 150lbs ( about 68kg of mass)

I know Power = Force x Velocity but then what?

I've tried picking an arbitrary velocity to find Force, but I am unsure what this result represents.

Say friction is negligible and velocity is at 9 m/s. So 1492 Watts = Force (N) * 9 m/s

which leads to Force = 165.7 Newtons.

Is it appropriate to move onto F=ma with this result? That would lead to acceleration = 2.44 m/s^2 but I am unsure of these calculations.

Thanks
