IDbike patent used by Giant
The first Giant bicycles with automatic chain tensioner can be found in the shops.
The tensioner was developed and patented by IDbike and now is used by Giant in several electric bike models.
The chain tensioner will compensate for all wear during the complete life of the chain.
The chain does not have to be adjusted anymore and can stay on the bike for the complete lifetime of the bike.
