I am beginning to think there is an Indian collage that has set their students a design task more then likely without the build element as a hybrid kart isn't very practical.
Your not going to get anything lighter than using a clutch to connect between the two drive units - BUT engineering wise this isn't going to be easy.
I worry that you skill set is such that you don't already know about this.
When I design something I spend weeks thinking, reading and drawing to come up with some kind of working design. I look at what others have done, I look at commercial examples, I look at theory. Then I try to select out those ideas that might fit what I want to do.
Asking general, open questions here isn't getting you down that road.
We don't know your skill set, we don't know your budget,
We don't know how far you have already got.
We don't know what materials or workshop facilities you may have access to - All these things makes a huge difference.
You could magnetically link the 2 motors to the drive shaft so 1 could disconnect allowing the other to run on. Connecting both would allow the motor to charge any battery you have.
You could use a hydraulic motor and drive 2 pumps from the 2 motors - simple valves would allow changing drive from one to another.
You could build 2 large gyroscopes. each driven by one of the 2 motors. Arrange them so that the gyro can precess freely in the forward direction but at the front limit they couch a track. This cause the shaft to run backwards along the track imparting a forward motion to the vehicle.
At the rear end the track lifts up so that the gyro goes into precession again moving forwards to repeat the process.
Now Valid or not, your not actually going to do any of these because they are complex, heavy and expensive. So start reading, drawing and thinking.
PS as a generality this isn't worth the effort any hybrid system that can be driven by a 125 cc motor is going to be so heavy it will outstrip the value of the hybrid system better look at -
Someone with the exact same question didn't even know his cost budget, what is yours ?
In your hybrid I would use an electric motor whose shaft is actually the wheel axle.
This allows simply disconnecting the motor wire to uncouple the electric motor and if you chose the right one it can also be made to generate electrical power for the battery and maybe regenerate when braking That means you can convert vehicle inertia back into stored electrical power.
Now you can use a manual belt pulley clutch or a centrifugal clutch as the engaging mechanism for the IC engine. Very simple, I hope I get best answer from you for this design.
Weight consideration will probably make this a nonsense. Small engines and electric power need very light weight to be effective.
It's all in the transmission. Most hybrids will run off the motor on start up then after a certain speed the engine starts and the transmission switches over to the engine. Not a viable option for something as small as a go kart. Id say it would be best to run the kart off the motor only and use the engile to charge the batteies on the go.
