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.

If you want to make your bike faster - pedal faster.

It worked for Chris Froome and Bradley Wiggins.

Use a Contact adhesive to stick it back on the switch.

Change out the gears with a higher ratio that turns the wheels faster for the same motor RPM. Another method is find a motor that has a higher rpm capability.

the plastic cover is what holds the batterie pack and prevent it from sliding out.
yur pretty lucky the pack stayed in place, dont try that again.

i had the same problem and after a while i discovered that it was overheat! inside the frame is the batery and beneath of it is the power system. i beleive that its possition is wrong! ok , it must be sealed so it can be protected from water but dont forhet that it is aircooled!!! when i opened it and tried to remove it was burning hot! that must damaged something inside there...but after a while it started again like nothing happend! i left the bottoms plastic open and i pushed it to its limits! as long as the overheat safety was on the open air ihad no problem! when i closoed it up it started not working again!

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......
