Between those two models, I'd go with the CrossRip for the better riding position and ergonomics during those "motor off" periods. But who are you purchasing the bike from? Is your local Trek dealer Bosch Certified (or whatever Trek requires their ebike dealers to be)? I'd only be willing to purchase from a store that was setup to assist with all aspects of after service support. Any Trek shop can fix a brake issue, but ebikes require different equipment and support networks.
