In the latest YouTube video on the Enduro Ren channel, the Grundig Pedelec GCB-1 is presented in detail. The tester provides detailed insights into the unboxing, assembly, as well as his first riding tests and experiences with the e-bike.

Unboxing and Packaging

First impression

The e-bike is delivered in an oversized box, the condition of which already raises some concerns upon arrival. The tester notices that the packaging is damaged and the bike was partially unprotected inside the box. These circumstances raise questions about quality assurance and transportation.

Contents of the package

• E-Bike itself: Equipped with a Bafang M410 mid-drive motor.
• Accessories: Charger, mounting tool, and an instruction manual.
• Extras: A sprung saddle and a hydraulic disc brake from Tektro.

Assembly process

Step-by-step guide

The assembly of the Grundig Pedelec GCB-1 is described as simple, but requires attention:

1. Handlebars and Pedals: The handlebars must be adjusted and the pedals attached. It is noted that one pedal has a left-handed thread, which should be taken into account during assembly.
2. Brake lines: The tester discovers that the brake line for the rear wheel is damaged and the front brake line is too long. This is considered a potential safety risk.
3. Fender and lighting: The installation of the fender and the lamp is also mentioned, with the latter seeming somewhat cumbersome.

processing

The processing of the frame is described as high-quality, but the problems with the brake lines raise questions. The tester suspects that the damage is due to transport, as the box was already torn and had no carrying handles.

Technical Specifications

• Battery: 36 volts with 500 Wh, enabling a range of up to 100 km.
• Motor: Bafang M410 mid-drive motor, known for its reliability and performance.
• Brakes: Hydraulic disc brakes (Tektro) with a 180 mm disc at the front and a 160 mm disc at the rear.
• Gear system: Shimano Altus with 9 speeds, which initially needs some adjustment.
• Frame height: 52 cm, which also allows taller riders to ride comfortably.

Driving experience

After assembly, the tester performs an initial test run. Several problems occur during this process:

• Steering behavior: The steering feels resistant and imprecise, which indicates a possibly faulty assembly. The tester notes that the bearing is set too tight, making handling difficult.
• Chain: During another test ride, the chain unexpectedly breaks. The tester suspects that this is due to a poorly installed chain lock, which is very dangerous.
• Motor power: The Bafang motor runs smoothly and powerfully, making riding enjoyable.
• Brakes and Gears: The hydraulic disc brakes and the Shimano gear system work reliably and without problems.

Conclusion

The Grundig Pedelec GCB-1 has both strengths and weaknesses. While the second bike shows that the product has potential, serious problems were found with the first bike, which could be due to poor workmanship or transport conditions.

Recommendations for buyers

• Check packaging: Buyers should pay attention to the integrity of the packaging to avoid transport damage.
• Spare parts: It is recommended to carry a spare chain, as chain breaks during use cannot be ruled out.
• Initial check: Before the first ride, all parts, especially brakes and gears, should be thoroughly checked and adjusted if necessary.

Overall, the Grundig Pedelec GCB-1 is considered a good choice for e-bike riders, provided the mentioned points are taken into account. The potential for a pleasant riding experience is there, and with proper care and maintenance, it could be a worthwhile investment.
