The PowerTube 500 enables trekking and eMountain bikes to take long distances in their stride. Thanks to its compact size and minimalist design, the battery can be integrated within the eBike to ideal effect. The sophisticated technology of the lithium-ion batteries that can be integrated within the frame ensures carefree riding enjoyment, while a safety catch prevents the battery from falling out even on challenging terrain. Nevertheless, the batteries can be removed with ease.
