Why isn't it worth it? It seems like free energy. Or is the weight a problem?

- jeffbee 5y agoMost of the energy is being lost to wind resistance and rolling resistance and parasitic friction. The fraction you can regain by recovering potential energy down hills, multiplied by the round-trip generator-motor efficiency, just isn’t relevant to the overall experience.
- wolverine876 5y agoThanks. A couple thoughts: I read somewhere that rolling resistance didn't add up to much, but maybe I need to recheck that. Also, I wonder if it's different for city riding, where riders need to stop every block or two and start again.
