If you want to ride with a bitless bridle, you can opt for a Hackamore. Your horse will not have a bit in the mouth, but due to the leverage of the Hackamore you exert pressure on the nose, chin and behind the ears of the horse. Also with a Hackamore applies; the longer the cheeks, the sharper the effect. It is also very important to fix the noseband at the correct height when you are going to ride a Hackemore.
