I am in the same boat, and am considering a significant commute. The trains in NY have been brutal, and I am considering biking 3-4 days a week (35 miles each way). I can handle the ride without assist, but this gives me a margin of safety and maybe cut 20-30 minutes on the trip.
Here's an odd question: How do these e-bikes work in crappy weather, such as rain? I considering some of the bikes above, as well as a Specialized Turbo or Stormer ST1 - looking for a "factory" bike, rather than a kit.
(I put this in e-bikes, but it might be better in the Commuter forum)
Any advice would be welcome. I've been testing with a CAAD 10/4 and a mountain bike with slick tires, but the electric would make a difference.
