The GRUNDIG GCB-1 is the company's first e-bike and marks GRUNDIG's entry into the e-bike industry. Although GRUNDIG is primarily known for its products in the radio and television industry, the company now also wants to gain a foothold in the e-bike sector. The GRUNDIG GCB-1 is presented as a promising means of transport for everyday urban life and is ideal for shorter journeys such as going to work or shopping.
GRUNDIG has made the GCB-1 available free of charge for a test period of one week. In this test, the e-bike is examined in detail for its performance and properties. The following aspects are covered in the test report:
The GRUNDIG GCB-1 is a unisex bike and is offered in a single frame size. The aluminum frame of the city bike is of high quality and has an integrated guide for shift and brake lines, which results in a clean look. The e-bike is available in three colors: lava gray, light gray and ice blue.
The GRUNDIG GCB-1 is powered by a powerful 80 Nm Bafang motor. The motor is powered by a 540 Wh Li-ion battery with LG cells, which can be removed from the frame. This makes it possible to charge the battery separately or replace it if necessary. In the test, the almost empty battery was fully charged in just over 7 hours using the included charger.
