Revel turns to software to keep its e-moped fleet powered without straining NYC’s grid Revel is turning to an app that gamifies energy use to keep its fleet of more than 3,000 electric mopeds charged without putting a strain on New York City’s power grid. Electricity is the key ingredient for the Brooklyn-based startup, which has more recently expanded beyond shared electric mopeds and into e-bike subscriptions, fast-charging infrastructure and even an all EV ride-hailing service. It’s not just about accessing power; managing when that power is tapped will be essential for Revel to keep its operational costs as low as possible.
