What do you think about the Felt Outfitter? It's running the Bosch Performance eDrive with 250 watt output and a 500 watt hour battery. The outfitter comes in 3 sizes: Small (16), Medium (18), and Large (21). No suspension here, because you can adjust the pressure in those fat tires for some extra comfort. Instead, you get the: Felt fat tire rigid fork, oversized hollow crown, hydroformed 6061 aluminum blades, aluminum tapered steerer, 150x15mm maxle style dropouts, disc-brakes, and eyelets for accessories.
More detailed technical specs can be found directly on the Felt website linked HERE.
If you haven't tried an eBike, and especially a FAT eBike, please don't hesitate to call me here at Small planet eBikes to schedule a ride. I have a few different models to choose from so please try them all.
