The most of bicycles with 26” or 28” wheels are suitable for mounting kits with gas engines.
We don’t recommend lower class bicycles for power assist

  • We recommend male type of frame due to higher durability
  • The frame should have hard tail
    The engine is placed between saddle and rear wheel, in practice it leaves no space for wheel travel.

  • Mountain bikes
  • Cross bikes 
  • Trekking bikes
