Hub Drive Vs Mid-Drive:

  • Mid Drives feel like you are riding a bicycle, but you are Superman!
  • Mid Drives need to be shifted, like a bicycle.
  • Hub Drives do not stress your chain.
  • Hub Drives sometimes offer regenerative braking.
  • Hub Drives are weighted more to the rear, so they handle different.
  • Hub Drives feel like you are on a (possible underpowered) motorbike.
