Is that round-trip or one way? A short commute is <10 mi. r/t. Anything longer is a moderate commute and IMO would benefit from more than 7sp. I'm shopping for a commuter myself for a 30mi r/t 3x/wk. It will either be a factory OEM e-bike or an e-assist kit added to (short list): Raleigh Redux 1; Salsa Journeyman 650; Breezer Midtown 1.5. I've set up many a flat-bar hybrid bike with the usual commuting amenities (Planet Bike Rack/Fenders/Lights or Bontrager Rack/Fenders/Lights) and buying them myself is better than getting a factory specific commute bike for twice the price with ho-hum parts.
