Kona Minute midtail cargo bike w/ dual 350W MAC kits, 36V/15Ah Headway battery kit, and CA V3 - heavy but very stable, eats hills. GT Timberline MTB w/ integrated torque-sensor motor, sine-wave controller, and LCD display - nice, smooth, quiet ride. Ultra Motor Europa pre-built - good range, but noisy brushed Heinzmann motor struggles up hills.
