Well, I guess I want a robust EV, from what I see with a Bosch electric motor, probably a belt drive. Commuter bike, low frame, disk brakes. Transmission, dunno, Bosch or from what I see, maybe Pinion? I think Shimano doesn't make belt drives.
I have an e-bike like that, belt driven commuter bike, removable battery in the frame (you want this, as it lowers the center of gravity compared to a battery under the cargo rack), disc brakes, 7 speed transmission, from a A-brand, etc. Basically this bike: https://www.batavus.nl/elektrische-fietsen/finez-e-go-power-... (although this is the 2023 model and mine is a few years old now)
The listed price (€3699) is about the same as what I paid for it back then. I made one upgrade to it, by replacing the standard display with a Nyon (which includes satnav among other things) which added €400 to the price.
Awesome bike, absolutely the best bike I’ve ever owned. Rock solid, nothing rattles even on rough terrain or going over speed bumps. I highly recommend the satnav if you plan on touring around. You can pre-plan routes on your PC and upload them to the display (it has wifi). And with the belt drive it’s completely silent, which is nice if you like to tour through nature like me.
Those requirements will make the bike expensive. Belt drive you don't really see on bikes below €1000. A pinion gearbox is €1000 by itself.
So what you're saying is you want a S class for the price of a VW golf.
