MotoTec dirt bike has 3 setting for speed but each setting is under powered.. On high the bike might hit 10mph with 50 pound rider on asphalt.. Batteries are good and run forever on a charge. Fix?

You get what you pay for.
The setting for speed are 5,10,16 mph.
You want anything faster you would have to do major rewire of the bike to over volt and current on the motor and additional batteries - cheaper to buy a faster bike.

What size batteries would i need to go farther? can i put a bigger hub motor in it

Depends on the watt of the motor to use a bigger battery, or it may damage the motor. and a bigger hub motor can damage the battery and the motor itself......
