Helabike / Communication and Service


To prevent head injuries , the need of bicycle helmet is very important.
We don’t know when we want or need to use the public bike for sure. So if the helmet can be rent with the bike , the safety of riders will increase.
With our system , Riders need to rent the helmet first to unlock the bike . And the helmet can be separate to two parts. The inflatable liner pad can be attached to the helmet or removed for cleaning . The air-filled bladder inflates through air-pump technology to support your head with a customized size.
