I have a 10 speed (2x5) road bike, a French motobecane from the late 80s or the early 90s. I just got it and the first thing I did was replace the rear rim, tire, and tube. It is all greased up. When I am in the two highest gears the chain likes to skip/slip/jump, especially when I am pushing as hard as I can. If I try to pedal softly and evenly it will be fine, just when I press hard. What are some things that could be causing this? This has a freewheel and not a cassette.

I would guess you have a derailleur problem, freewheel or cassette it doesn't matter or make a difference.
The 1st thing to address would be make sure your tension bolt is adjusted to the proper tension.
If this doesn't work you may have to adjust your high and low adjustment screws which will adjust your pulleys with your top and low gear.
This is done by shifting to the lowest gear and turning the low adjustment screw or bolt so that the guide pulley moves to a position directly below the low gear and then repeat the process again using the high end adjustment bolt with your highest gear.
After that try adjusting the adjustment bolt, it's on the back of the derailleur the one the cable runs through.
1st put your bike on a stand and put your chain on the second smallest gear and turn the crank slowly, if your chain is touching 3rd gear turn the adjustment bolt clockwise until the chain noise is gone.
If it's touching 1st gear then turn it counterclockwise until the noise is gone.
Following the procedure should solve your problem.

The teeth wear naturally over time. You may need to take it into the shop for some new parts .. or don't pedal so hard for now ... but in time even the least bit of pressure will cause skipping on the gear that's most used.

its most likely a worn freewheel or chain. i have had this same problem in the past, i no how you feel.
replace the freewheel, you can get a good quality shimano for around $30. a new chain will cost around $25 for a descent one. i would replace both just for safety and to save time.

common problems: chain worn, teeth on gears worn, deraileur out of adjustment.
it can be a bit of a pain, but check all these things. if too much work for you, don't be embarrased and just take it to your local bike shop. good luck and ride safe!

his roblem could be caused by, the derailleur being not alligned or the teeth of the gears to be dull and worn down.
