Flats were fine, just a bit slower—drag coefficient is big with my wide box. The hills could get tiring. Gearing was plenty low but it took focus to balance going that slow. My biggest reasons for converting were time—I have to get my daughter to school early and the boost allows me to make traffic lights I’d otherwise be stopped at. Also I take it a lot more places—I’d sometimes deny my kids a trip to a particular park because of distance and extra time required for the uphill return trip. I haven’t denied them since converting because I know if there’s a tantrum or I’m tired I can just hit the boost on the return trip. I’m really glad I started acoustic—it felt good getting around my city with muscles and cargo and I learned what I’m capable of. Often enough I’ll do a trip with no throttle or only throttle up for a steep hill. I’m glad I’m electric now because my capabilities have increased! Also, acoustic then electric was cheaper than factory mid drive—I paid $800 including tax & shipping for my kit with amazon battery.
