  1. How about using hub motors with a couple of 1 F supercapacitors (e.g. ones designed for car audio use)? With good enough ESC that should be able to do pretty good regen and instant power output with very little mechanical losses. For example, 3 F worth of capasitors and 50 V voltage, your power storage is about 3700 J which should be enough to stop and re-accelerate a bicycle. Supercapacitors should be a lot lighter than Li-ion battery pack so it should improve the overall handling a lot.

  2.  @vennox1598  As I wrote, "it should be enough to stop and re-accelerate a bicycle". I totally agree that supercapacitors are not energy storage method in general but for stop and go solutions that could be exactly what you're looking for if you are willing to get the energy for continuing continous movement from somewhere else.
