Navigation for deaf / Navigation for deaf

This product is designed for hearing-impaired people to have a chance to ride a bicycle. We sometimes can see these people at any kind of place. They are not able to ride a bicycle mainly because they cannot notice any sounds around them. There is no doubt they will be more likely having an accident especially when anything comes from behind. Using this navigation, they can notice sounds around them so it will be a lot easier for them to ride a bicycle without worrying about an accident.
