It is a simple problem with simple solutions. You have the back wheel and you must somehow transfer some torque to this back wheel. You can use a chain, or gears or a shaft. Oh, we do like the motors that have shafts.

My first real motorcycle had one of those. It was a Yamaha Virago 535 and it was a great motorcycle. The shaft is sometimes also called the "cardan shaft" and is just a rod attached on one and to the motor and on the other end to the wheel. Of course, there are a couple of gear wheels involved and it is also possible to have a number of rods, but at the end, the principle is the same.
Would this robot move faster or move slower.
Fast and slow is only relative to the previous robot in the course. What you should do is try to construct the robot and inspect the shaft that is transferring torque to the back wheel. See how it works. Before even starting the robot try to guess if this robot will move faster than the previous.
What is the question?
Again the question is about balance, Is the robot falling on one side? When? Can you turn with the robot without the robot falling to its side? How to make the robot turn?
It's fast. It's on two wheels. It's a motorcycle. And this one is built from LEGO Mindstorms EV3 sets with the use of one additional Medium Motor. If you have two medium motors, great. If you don't have you can build the Handlebar - Chopper Motorcycle built with LEGO Mindstorms EV3, because it uses one large and one medium motor that are available in any EV3 set.
Currently, the motorcycle has no sensors. It's more of an exercise in construction, but if you attach sensors and think of a way to attach them send us a picture.
Join the course A robot a "day" keeps the questions awake where we will further discuss the motors, how to build them and what tasks to accomplish with them.
