Scope of delivery and packaging

The ETB2800 is delivered in an impressively large box, which offers more space than many other e-bikes. The box is twice as large as usual and contains all the necessary parts for assembly. The contents include:

• Pre-assembled e-bike: The handlebar is rotated 90 degrees, the saddle and fenders are already installed.
• Accessories: Pedals, charger, assembly tool, and a detailed manual are included in the scope of delivery.
• Packaging material: The manufacturer uses little plastic, which is environmentally friendly. The majority of the packaging consists of cardboard and recyclable materials.

Assembly process

The assembly of the e-bike is simple and intuitive. The entire process should take about 5 to 10 minutes:

1. Attach pedals: The pedals only need to be screwed onto the threads with some grease.
2. Align handlebars: The handlebars must be positioned correctly and fixed with a screw.
3. Completion: After these steps, the bike is ready to ride.

The manual is well illustrated and covers all the necessary steps, which is especially beneficial for users without much experience in bicycle building.
