Hey Johnny, I have a bit more data now that I've done the commute a few more times (starting this week I'm at 4 days a week, 2 days using the train and 2 days going the full 14 miles).
So far, my average MPH is trending upwards. I'm starting to hover around 20mph for the whole trip. If I hit the lights right I can get the commute done in sub 40minutes. I've done that now twice, and I wasn't overly tired afterword.
The bike has been stellar so far, had an issue with the front brake pads rubbing on the rotor, so I took it in to the shop and they adjusted the rotors under warrantee. I can do the whole commute in a single charge if I wanted, but only on either Tour or Eco settings. If I leave it on turbo I definitely can't make it on one charge.
