is there any motor that have a traction on crankset ?

Hi,
I checked many 80cc motors for bicycles on aliexpress but all the models does have a "rear" wheel traction.
I don't like this design because it does not allow a rear disc brake.

is there a model where the motor chain is located on the crankset instead ?

Do you mean something like this?

Front and rear disc brakes, triple chainring shift kit, all shifting is done with the left hand.

Yes, you've done a good job
