there seems to be a new Mid Motor for weight weenies:

somewhere it says 2.5 kg which is quite good for a retrofit Mid Motor. No torque sensing however.
Gospade is Cadence pas drive and about 2.6kg.
Here in UK Woosh bikes have said they have a 100nm custom option on order for Autumn delivery, unsure whether it is 36 or 48v though will be marked 250w to compy with UK/EU law.
