Your bike's front wheel may be squeaking due to lack of lubrication, worn out bearings, or misalignment. Regular maintenance and proper care can help prevent squeaking.
Front wheel drive bikes offer better traction and stability, especially in wet or slippery conditions. They also provide a more efficient power transfer from the pedals to the wheels, making them easier to ride uphill. Additionally, front wheel drive bikes tend to be lighter and more maneuverable than rear wheel drive bikes.
so that you can see which speed your going

Most likely either your brake pads are worn or you have a wheel bearing going out. Hard to tell without knowing more specific details of the squeaking, conditions it occurs under, etc.

The pro Senior has 12" front wheel and 10" rear wheel and the Pro Junior has 10" front wheel and 10" rear.
It could worn out wheel bearing.
They came in different sizes, but the radius of the wheel had to be less than the inseam measurement of the rider.
Some bikes have disc brakes on both wheels, but the front brake is more important. During braking you'll encounter something called dynamic weight transfer, which basically means that more of the bikes weight will be supported by thr front wheel and less by the rear. As the front wheel gets heavier the friction against the surface increases and it'll be to brake even harder, causing even more of the bike's weight to rest on the front wheel. All this heavy braking means that the front brake needs to be better at dispersing heat and it needs to be more easily modulated, as it's very hard to recover if the front wheel would lock up.
Your rear wheel may be squeaking when turning due to worn out wheel bearings or lack of lubrication. It is important to have it checked by a mechanic to prevent further damage.
Front suspension bikes have suspension only in the front fork, providing cushioning and shock absorption for the front wheel. Full suspension bikes have suspension in both the front fork and the rear frame, offering cushioning and shock absorption for both wheels. This allows for a smoother ride over rough terrain and better traction, but full suspension bikes are typically heavier and more expensive than front suspension bikes.
Don't know any penny bikes, but there were penny-farthing bikes. These had really big front wheels, with the pedals attached directly to the wheel axle, and a quite small rear wheel.
