Cyclists lack affordable, reliable bike computers with long battery life and open-source customization

Cyclists are forced to choose between expensive proprietary bike computers with limited features or smartphones that drain battery quickly and lack durability in outdoor conditions. Existing solutions either lock users into closed ecosystems with vendor lock-in, lack integration with open sensor protocols like ANT+, or require constant charging. Open-source alternatives with eInk displays that solve battery life and weather resistance remain inaccessible to most riders due to complexity and lack of commercial availability.
