The hub motor I have on one of my bikes will literally flip the bike over from a dead stop, even if I'm leaning on the handlebars, if I'm not gentle on the throttle.
The one on my trike will beat most sports cars to 30mph, also from a dead stop.
@OP, be aware that if you don't plan to charge the hybrid batteries, the periods where the motor is dragging on the car to charge the batteries needs to be just as frequent as when you're adding power, or your batteries will run flat and never get charged again. You can't just cruise along on the highway adding electric assist forever, without ever charging the batteries. That energy has to come from somewhere. You also don't want to charge the batteries while simultaneously draining them... it's like pressing the gas and brake pedals at the same time.
Most manufacturers choose to assist when you accelerate, recapture energy when you decelerate, and very occasionally sap power when cruising if there's a deficit. Sometimes when idling, they'll also apply some load to the engine to slowly top up the batteries. But, again, that energy all ultimately comes from gasoline, it's just a matter of figuring out the best times to give and take.
