Through the extensive use of hydroforming on the down tube and the precise laser cutting of the tube opening for the battery, as well as the perfectly matching two-component plastic cover, we were able to integrate the battery seamlessly into the lower part of the down tube. This is consistent throughout the various frame sizes. Charging is easily possible through the nicely integrated charging port at the motor bracket. Also, the battery is perfectly integrated into the down tube, yet it is possible to remove it for charging or when in transport. A further advantage of the battery being integrated into the down tube is the perfect protection from an impact which can occur when the bike falls over or is involved in a crash.
With the additional hole in the down tube, the battery can be turned on from deep sleep mode. That’s necessary when the bike is not used for longer than 6 months, or when the battery of the on/off switch is empty (this battery is normally charged by the main battery). To wake up the battery, just push a 4 mm Allen key (best to use the MERIDA EXPERT TR axle) through the hole, pressing the hidden button underneath.
