I rode Trek hybrids for years - until we bought a place smack dab in the middle of some big rolling hills, just 5 miles from a 46 mile bike trail. They didn't seem that daunting when driven in a car, but on a bike, the wife and I were wiped out by time we got to the trail! No choice but to turn around and head home. We lost interest in biking because of those hills. Too much! Then somebody mentioned e-bikes, and I was like a dog seeing a squirrel..... Prior to that mention, I hadn't even considered one. Just didn't occur to me! Things haven't been the same since....
I sold the his and hers Trek hybrids because they were just collecting dust. Fun seeing the big grins on the buyers. They we really happy to find a pair that had been well maintained. Felt good selling them to somebody that would enjoy them...
IMHO, with a good PAS system in play, weight is not an issue (within reason). You're going to choose a PAS level that let's you pedal at a level of effort that you choose. From there, the motor is handling the weight. If you are talking about the big tires FEELING heavy, it might have been they were not inflated properly for your tastes. Messing with the pressure in those big tires is important as the "feel" will change quite a bit with just 5 psi difference. Makes it hard to really get a good feel on a demo ride....
Best of luck on your hunt. Keep asking questions! -Al
