"There will also be an optional Level 2 charger module available to fill the negative space left in the front of the frame. That would allow riders to charge at public charging stations, likely offering an even faster charge. Other accessories that will be available to fill that cavity include a storage compartment or a 3,000Wh auxiliary battery to extend the bike’s range. Riders can of course leave the space empty to retain that futuristic look." Source: https://electrek.co/2021/11/19/exclusive-first-look-at-the-production-ready-sondors-metacycle-electric-motorcycle/
