Clarification Board Ask a Question

  • Asad C.

    1/ Could you clarify how the marketplace should work from the rider's perspective, including searching for bikes, viewing availability, selecting a bike and completing a booking? Should users be able to choose a specific e-bike, or should the system automatically assign an available bike based on location, type or fleet rules?

    2/ What information should fleet operators be able to manage for each e-bike, such as battery level, GPS location, maintenance status, mileage, availability and ownership?

    3/ How frequently should the e-bike GPS location update while a ride is active, and should tracking continue when the ride is paused or completed?

    4/ Which payment methods and currencies need to be supported, and should payments be processed through Stripe or another existing payment provider?

  • VCONN P.

    Hi Sam,

    Before moving ahead, could you share the current stage of the project, including whether there’s an existing codebase/design, and if the blockchain network and CO₂ token requirements have already been defined?

    Looking forward to your reply.

    Best,
    VConn Pvt Ltd

    Hi Sam, Do you already have an existing platform/codebase, or is this being built from scratch?
