It isn't really a clutch. This transmission design is most commonly found on motorcycles, with the addition of a clutch of some sort. An electric motor allows you to remove the clutch, simply due to the fact that the motor works from 0 rpm onward. An IC engine on the other hand, has an idle that would otherwise prohibit the vehicle from stopping completely without a nuetral position or a clutch. The starting and stoping are the primary needs for a clutch with an IC engine/motorcycle tranny. It is quite common to not use the clutch when shifting a motorcycle by simply easing off the throttle and engaging the next gear so long as you are already moving.

By clutchless, I meant lacking a means to engage or disengage the power coming from the motors feeding the output shaft.
