Cant see having this on my race bike, but seems like a no brainer on a commuter bike.
It’s a little generator with a removable battery pack with its own USB port that you can charge a device anywhere. Then plug the battery back into the bike’s generator system and charge the battery pack.
You can also charge a device on the fly while cycling. Like the article’s accompanied video says, the product’s not revolutionary and going to end the world’s energy needs, but it’s a nice little step forward.
