Freegen ebike regenerative braking hub mechatronic discussion
The YouTube video discusses the "free genen" concept for electric bicycles, combining freewheeling and regenerative braking in a hub motor. Developed in Israel, this system enhances efficiency and control by adjusting regenerative force based on braking intensity.
Read original articleThe YouTube video delves into the innovative concept of "free genen" for electric bicycles, merging freewheeling and regenerative braking in a hub motor. Developed in Israel, this system incorporates a clutch mechanism to seamlessly integrate both functions within a single motor. By attaching the disc rotor to the planet carrier inside the hub, the design enables zero drag coasting and regenerative braking, enhancing efficiency and control. The braking system in the Insight by Wheel So Alon is distinctive as it adjusts regenerative force based on the rider's braking intensity, eliminating the need for extra sensors. This is achieved through a six-magnet wheel speed sensor in the geared hub motor, offering a sophisticated yet intuitive braking experience for electric bike users.

Show HN: I built a large JavaScript powered flipdisc display. Here's a guide
Flipdisc displays, or flip dots, use electromagnetic pulses to switch colors. A project details building a large interactive display for offices, covering construction, power, software, and design considerations. It aims to explore real-time visualizations and user interactions, hoping to make flipdisc technology more accessible.
Rolling and Wheels in the Natural World
Living organisms utilize rotation for movement, but wheels have not evolved due to genetic and structural constraints. Examples like pangolins and dung beetles demonstrate alternative rotation mechanisms in nature.
at least this adds a bit more granularity than the lame off/on ebike e-brake switches that are most popular right now -- but it sucks that it's at the loss of pad life rather than just sticking a dirt cheap hall sensor on a lever somewhere and leaving the pads for emergencies.
it is very clever, though.
So a big negative for me is the added complexity and dependency on bike shops for simple things as changing wheels.
