I have been shopping for a few weeks now and have test-driven Trek Verve, Electra Townie, Momentum LaFree, Liv Amiti, and my favorite: Aventon Pace 500. I love the Pace for its price, zip, display, weight, hydraulic brakes, and throttle... but I don't like its speed at take-off and the lurching. The others, are okay, a little more than I want to spend, and don't have throttles or nice displays. However, I've seen several well-reviewed bikes online that have the features I want, particularly the throttle and the lower price. I'm particularly interested in the Espin Flow. My question is: Should I buy the Espin (or something else, like a Blix) and hope that a local bike shop will be able to help me with assembly (if necessary) and future service, or should I stick with one of the "safer" choices from an LBS?
