    Dolphin Derailleur Hanger Replacement

    It seems like my derailleur hanger is bent. After a bit of research, it seems the Dolphin uses a Shimano Tourney Long Cage Rear Derailleur 6/7-speed or the model name is RD-TY300-SGS. I was wondering if anybody knew which derailleur hanger is compatible with it? Thanks!

    What happens when the battery dies?

    Question for Dolphin or Volador owners, what happens when the battery runs out on a ride? Can you still ride it like a bike or does it lock up? Also curious, does the Dolphin come in red? It seems like the one reviewed on YouTube by ElectricBikeReview but it doesn't seem like they sell it anymore.
