My e-MTB(s) don't have throttles either, and in fact all of the e-bikes produced by the major manufacturers (Specialized, Trek etc) are pedal-assist only. Some have a 3-6 mph "walk mode" which is disabled by pedaling AFAIK. The e-haters like to consider this a throttle even though it's for walking up extremely steep terrain, stairs or whatever.
