Ofo's Debt Crisis and the Technical Architecture of Shared Bike Services

In late 2022, the Chinese bike‑sharing company ofo faced massive debt issues, with Zhejiang Tianmao Technology suing its affiliates for over 5.38 billion yuan and users still waiting for refunds of deposits.

The court documents reveal that ofo’s related companies are being asked to pay the principal and interest, while the founder Dai Wei faces multiple consumption‑restriction orders.

Ofo attempted self‑rescue schemes such as “shopping to refund deposit”, “invite friends to help refund”, and “10‑yuan special recharge”, which effectively required users to spend far more than the original deposit.

Beyond the financial troubles, the article explains the technical architecture of shared‑bike services as a typical “IoT + Internet” application built on cloud computing platforms.

The cloud‑based system consists of a cloud computing foundation, data assets (bike data and user data), platform services (PaaS), and integrated applications that handle payment, QR codes, and mapping.

The smart lock hardware includes control chips, modem, Bluetooth, GPS, sensors, actuators, buzzer, and power modules, enabling remote unlocking and management via the cloud.

Overall, the piece combines a case study of ofo’s financial collapse with an overview of the cloud and IoT technologies that underpin modern shared‑bike services.
