This is a recent electric bicycle conversion on one of our Shorthaul Cargo Bikes for a customer in Sydney. 36V LiFE PO4 battery pack and controller mounted under the seat inside the cargo box. This keeps the weight nice and low and the cabling nice and tidy. The battery pack has a locking carrier so the pack is secure but can be removed for charging off the bike if required. An LCD screen mounted on the handlebars allows the rider to choose how much assist they need.
