I still find the concept of the Magnic interesting! The ability to get power from the wheel without touching it means that there is no wear on the wheel or tire, no noise, and no worry about loss of power if things get wet or messy. I also like having the dynamo and light integrated into one package, not unlike the block dynamos of a few decades ago.

Everything has disadvantages, and the method of getting power from the wheel means that you aren't going to get a lot of power at low weight. To be fair, though, I don't know what the numbers for the Magnic are. I still have my old Jos block dynamo....



It delivers 3 watts (I think) and weighs 300 grams. It mounted to the fork blade.
The optical performance doesn't compare to modern tech. The incandescent bulb and rotten optics resulted in light that was only marginally functional. Modern optics and LEDs would be a huge upgrade. The drag was still significant compared to a hub dynamo, which I still think is the best solution for general purpose riding.
