Have a BF NWT with Nexus hub, traveled a few thousand KM during the past five years. It is setup primarily as a commuter with the JTek shifter. Bike/rider/stuff load weight is around 120 kg. Echo another's comments about gearing, a ratio that tops out about 80 GI is quite adequate for utility riding. No problems with the hub, ride it year around and in some pretty grimy conditions - lot more durable than a dérailleur set up.
