So if I understand this correctly, it uses the downwards force on the wheel when pushing down on the pedals and converts that into rotational force on the wheel.
Now, because of that annoying thing called conservation of energy, this means that you'll have to put this energy into the system by pushing down harder. I guess this translates to a feeling of sitting on a spring. That doesn't sound like very efficient pedalling.
- radu_floricica 6y agoI don't claim to understand the mechanics involved, but I think it's the equivalent of regenerative braking for suspensions. Instead of wasting the energy when you cross a bump, it stores it and converts it into forward motion. Pretty smart if it's so, and depending on road conditions I actually see it as having noticeable effect. Especially considering how crazy people are about upgrading their bikes.
- dclowd9901 6y agoNo. Not when pushing down on the pedals. Your natural weight would be all that would be needed to load the spring. At least that’s my understanding.
- lokedhs 6y agoSure, but when would the spring unload? You need to lift your body up do be able to load it again.
