I managed this, but then you're fighting the motor on many bikes: so it's not only adding to the weight, it's acting as a brake: I borrowed the company Bakfiets for a shopping trip once and my goodness my legs hurt afterwards: I used my bike with panniers after that.
The worst bit about that trip was I'd forgotten to get bog roll and that was the whole point of borrowing the bike in the first place...
It very much sounds like you don't NEED an e-bike, you are young enough to/ fit enough to use a "normal" bike. However, we (myself and Mrs
@BoldonLad) are 77/78 years old, after age 75, we found we needed a bit of assistance, so, e-bikes kept us cycling.
More recently, Mrs
@BoldonLad has been diagnosed with Alzheimers, she can no longer safely ride a bicycle (even an e-bike), it has nothing to do with her fitness level, which is upto the task, but, to do with dealing with traffic, gears, brakes etc. Even that has been solved by purchasing a Hase Pino Steps semi-recumbent tandem. So, we are still enjoying our cycling outings, and, keeping relatively fit.
I think the term "horses for course" may be appropriate.
Perhaps, more on. topic, when we rode our e-bikes (Specialised Vado 4 SL) we did get the very occasional "cheaters" comment, whilst riding the Pino, we have had only smiles, cheers and the occasional shout of "awesome", or "amazing" 😂
