We offer a Mahle X35+ range extender battery for $700, increasing your range by up to 70%.
How it Works
The range extender works like a secondary battery for the main battery installed on your ebike. On our ebikes, only the main battery provides power to the motor, while the range extender charges the main battery. The battery is charged regardless of whether the motor is demanding power (speed greater than 20 mph, bicycle stationery, or no pedaling). So, the range extender may not provide power to the motor independently without passing through the main battery. It is recommended to always connect the range extender to the main battery to ensure that the main battery stays charged.
In cases of intensive use of the bike in maximum assistance, and for long periods of time, the main battery may drain quicker than the range extender can charge. In this instance, wait for the range extender to charge the main battery to a sufficient level before riding again.
Functionality
Turning on:
Once connected to the charging point (Prolog & Dutch), click the IWOC button on top of the range extender. The iWOC button on the bicycle’s top tube will start to flash with the color indicating the bike's charge level, just like it does when the battery is being charged with the standard charger. The bicycle operates normally and assistance levels can be changed as if the range extender were not connected.
Turning off:
Press and hold the button on top of the device for 3 seconds.
Charging
The Range Extender can be charged independently or collectively with your ebike. To charge it independently, simply connect the X35 charger to the charging port on the top of the device.
To charge both the main battery and range extender, connect the range extender to the bike through the charging point and then connect the charger to the range extender at its charging point. The charging level is displayed by the iWOC color on the top of the battery.
