Brake too tight generally appears in the electric bicycle equipped with large-capacity batteries.
Because of the configuration of large-capacity batteries, natural electric bicycle themselves have to become heavy. Therefore, when the electric bike manufacturer leaves the vehicle at the factory, in order to ensure the reliable and safe braking when the vehicle is running, the brake is closed tightly, which results in the vehicle's current is large when no load is idling, and the self-consumption power increases.
The effective solution is to detect the no-load current after the vehicle is assembled and adjust the brake to the proper position.
In addition, EZ Bike reminds everyone that when using electric vehicles on a daily basis, it is best to perform brake calibrating every two weeks or so.
