Use them and huge fan, as no flats yet after a few hundred miles of city biking. San Francisco is leading city of car window smash and grab robberies so you literally ride on broken glass everywhere. Using 700X38C version so was concerned that I'd have flats everyday, but so far so good!
I like and use CygoLites because they are a good value and self contained where you don't need a separate battery. The Metro line is easy rubber band mount, USB chargeable and goes up to 800 lumens. I recently got the Cygolite 1300 for extra power at night but you can't charge is via USB...
Yeah I liked the Conduit which used the Shimano system but it rode harder because it didn't have the front suspension fork. Also noticed you could feel the Shimano kick in and wasn't smooth like the Bosch. Getting my wife the Lift+ though as the bigger tires smoothed out the ride.
Wanted to give everyone my impression after having purchased the Trek XM700+ and ridden it for over 200 miles on San Francisco hills as a daily commuter. Put a quick video on Youtube:
Cons First (cause there aren't many!):
1) One of the reasons I chose this bike was for brand and service...
