  • WD – 219: The Intelligent Companion of Shared E-Bikes

Short Description:

WD-219 is a terminal product within the shared two-wheeled electric bike industry. It is the latest ninth-generation IOT offering from TBIT. Its positioning capabilities and accuracy have been fully upgraded, supporting positioning modes such as dual-mode single-frequency single-point, dual-mode dual-frequency single-point, and dual-mode dual-frequency RTK positioning technology. The highest precision can reach sub-meter positioning accuracy, thereby resolving numerous issues caused by positioning drift during user return, operation and maintenance, and vehicle search. Simultaneously, the power consumption of the entire machine has been optimized, and the standby time is twice that of the previous generation of products. This significantly prolongs the standby time of the equipment after the E-bike battery is removed, further enhancing the safety of assets.


Product Manual

Product Detail

The development of shared e-bikes has brought great convenience to our travel, and WD - 219 is the intelligent companion of shared e-bikes, providing strong IoT support.

WD - 219 has a sub-meter level positioning function that can accurately locate the vehicle position and solve the problem of positioning drift. It also supports inertial navigation algorithms, enhancing the positioning ability in areas with weak signals. At the same time, its ultra-low power consumption feature significantly extends the standby time.

In addition, this product supports dual-channel 485 communication, and the peripheral accessory expansion is stronger. It can support high-flow data return such as AI camera pictures without affecting the data interaction of the battery and the controller. It also supports industrial-grade surface mount technology with stronger anti-interference ability.

Choosing WD - 219 means choosing intelligence, convenience, and reliability, making the operation of shared e-bikes more efficient and the user experience better.
