Highlight 1
The integration of video display in a bike light offers a unique feature rarely found in conventional bike accessories, creating a standout product in the market.
Highlight 2
The use of an ESP32 for Wi-Fi connectivity allows for seamless streaming of video frames, making it user-friendly and versatile.
Highlight 3
The precise angular resolution and high number of LEDs provide a captivating visual effect that enhances visibility and safety during night rides.
Improvement 1
The reliance on a manual process to periodically spin up the device when it slows down could be automated for a more seamless user experience.
Improvement 2
The necessity for the video camera's shutter speed to be adjusted can limit usability; developing a broader compatibility could appeal to more users.
Improvement 3
A more detailed user manual or troubleshooting guide would assist customers in understanding setup and operation better.
Product Functionality
Consider implementing a feature that allows the bike light to automatically adjust its rotation speed or alert the user when it needs to be spun up.
UI & UX
Enhance the user interface for the control server with more intuitive icons and layouts that simplify navigation and setup processes.
SEO or Marketing
Develop a content marketing strategy that includes engaging video demonstrations of the product in use, which can be shared on social media to attract interest.
MultiLanguage Support
Introduce multi-language support to cater to a wider audience, ensuring the information is accessible to non-English speakers.
