Please clarify my UNCONCIOUS doubts

I want to make a two-wheeler with a rated voltage of 48V and 1.4KW BLDC motor.

Two main variants I need:

I need one variant with high torque and the other with the high speed.

Can someone give me a solution How it can be done ??

My question is for making the vehicle to run in two modes ( An two wheeler)
1) High speed ( approx 60kmph).
2) High torque for load carrying without any top speed.

Making what changes can I achieve that two modes.

By making this does my mileage affects ??

Use 2 sets of chains and sprockets.

1 set with a high gear ratio for the torque.

1 set with a low gear ratio for the high speed.

This looks good but Can I make something without using that.

Example: using a controller can I use this mode...

I'll be happy if you can clarify me!!!
