I prefer the front motor build the best for balance reasons, with a 48Volt 15Ahr Ping battery strapped into a metal wire office tray which is ziptied to the top of the Revive Rack. Shoppper panniers can attach to the wire tray, which both protects the battery (in a Plano 1412 plastic marine box), from falling over sideways accidents, and widens the pannier attachments to keep them off the wheel. Arkel panniers work well. They are an awesome ride around town and longer distances up to 30 miles with this battery, cruising around 21-22 mph. Always use torque arms with the bikes. The front fork is steel according to the magnet test, which is ideal for hub motors, with a standard 100 mm spacing. The rear 9C is a little bit "back heavy", but quite rideable, with both the motor and battery behind the rider. I think they make excellent ebikes. I wasn't that fond of them as a regular bike though, preferring my Rebike recumbent and my Sun EZ-Sport CX recumbent as regular bikes, although I've electrified those too!
