Anyone recall the two-speed automatic transmission Honda 750 and 450 motorcycles of the late 1970's?  I think Moto Guzzi also had a model with a two-speed automatic.  None of those models made the companies rich and they didn't stay on the market very long.  ;)  But a two-speed, clutch-less, transmission might be just the thing for an EV, if it can be made compact enough and perhaps integrated into one end of the drive motor. Of course it didn't work out very well for Tesla, but might survive on a motorcycle motor with less torque than Tesla had.
Re Moto Guzzi, you're probably thinking of the V1000 Convert. It  had a clutch for the 2-speed gearbox, and a torque converter. The 2 speeds were basically to provide the equivalent of a 4x4 vehicle's Lo/Hi ranges; IIRC, Guzzi launched the model as some police department wanted a bike that convenient for slow-speed convoy duties.
I think the Honda CB750A was similar, i.e., also had a clutch.

The 2-stroke 50cc scooter I had as a teenager in the early 1980s, a Garelli VIP/2, had a 2-speed automatic transmission without a clutch. No torque converter of course, but the 2 speeds made it accelerate better than the 1-speed mopeds (-; Any moderately fit bicyclist could still overtake me, though...

Speaking of Garelli's I owned one too. A 1969 125.  Photo attached. Honda Super 90s would blow right by me, unfortunately.  :'(

Cool, it had a front wheel hub motor.    ;)

That is a nice looking little bike though.  So simple by today's standards.

Here's what Jonny, oh and some car company named Porsche, thinks is the best way to get high torque off the line and high top speed over and over again. 

Skip to the 9:20 mark for the answer.    ;)                                                   But watch the whole video for fun.
