Project Brief

As the low-carbon lifestyle becomes increasingly popular, shared e-bikes have become an integral part of urban short-distance travel. However, battery replacement and maintenance are among the most time- and labor-intensive processes, increasing manpower requirements, resource waste, and overall operational costs. To address this, EB001 innovatively introduces a side-pull battery mechanism and a modular design to improve operational and maintenance efficiency, thus enhancing availability and fleet turnover rates. It also incorporates GNSS positioning and geo-fencing technology to facilitate precise dispatching for optimized regional e-bike distribution. EB001 helps turn the idea of green mobility into a sustainable everyday practice.

Project Innovation/Need

For managers:
- EB001 pioneers a side-pull battery mechanism, streamlining the battery replacement process by shifting from traditional vertical lifting to horizontal extraction—enabling one-handed battery replacement and boosting efficiency by 40%.

- With a modular design, core components can be replaced independently, cutting average maintenance time by 60% and reducing service costs.

- The application of high-precision GPS positioning and geo-fencing technology ensures accurate positioning and organized parking management.

- A smart system powered by AI and IoT monitors the e-bike’s real-time status and utilization rate to optimize dispatching and maintenance.

- The incorporation of urban transportation data enables smart collaboration between public transportation and EB001, helping create a green, efficient urban travel ecosystem.

For users:
- A low 420mm standover height and a wide step-through frame accommodate riders of varying heights, ensuring effortless mounting/dismounting and improved riding comfort.

- The reinforced L-shaped basket avoids debris accumulation for easy cleaning, enhanced by a coffee cup holder, further improving the user experience.

Design Challenge

Shared e-bikes often suffer from unattractive exposed cables that are prone to aging or damage, leading to higher failure rates and increased maintenance costs. To address this, EB001 employs an internal cable routing design to conceal all cables within the frame. This results in a clean and cohesive appearance for improved aesthetic appeal and enhances the vehicle’s safety and durability without compromising signal transmission and power delivery.

Sustainability

The frame of EB001, constructed from recyclable 6061 aluminum alloy, achieves exceptional impact resistance to ensure riding safety and structural durability, extending the vehicle’s lifespan and reducing resource waste from the outset. Benefiting from a modular design, the vehicle can be easily disassembled for efficient classification and recycling at the end of its lifecycle, contributing to a circular economy.

As a shared e-bike, EB001 encourages low-carbon mobility and alleviates urban traffic congestion. Integrated with a smart dispatching system, it significantly improves fleet turnover rates to minimize idle resources and operational input, supporting the development of a more efficient and sustainable urban transportation network.
