I mean pedaling would recharge the battery. So you could go for a longer ride (say cross country) and alternate between charging and depleting the battery, just like in a hybrid car.

Not sure if any exist. Recharging by pedal would require adding resistance to the pedaling. The added resistance is fine in a car because they’re so heavy and fast that it’s barely noticeable downhill. But it’d be very noticeable to someone on a bike.
