Transforming kinetic energy to eletrical energy requires a dynamo (same as a generator). The very process of converting kinetic energy to another energy form be it mechanical (flywheel) or electrical (battery) always result in a resistance to rotation. A progressive coupling/decoupling transmission helps. The peak resistance will be proportional to the amount of energy salvaged.
