Schlumpf Drive: The Perfect Addition to Your VELLO Bike

You’ve probably come across the term “Schlumpf Drive” while searching for your perfect VELLO Bike. Don’t worry, it has nothing to do with those little blue cartoon characters! Instead, it’s an innovative solution from Haberstock Mobility that significantly enhances your riding experience on a VELLO Bike.

The Schlumpf Drive is an ultra-flat planetary gear system located directly between the bottom bracket and chainring. Depending on the model, it offers either overdrive (Speeddrive) or reduction gearing (Mountaindrive). This means you can choose your Schlumpf Drive based on your preference—whether you want to ride faster or tackle hills with ease.

Why the Schlumpf Drive is Perfect for Your VELLO Bike:

• Compact and Invisible: It works quietly in the background, delivering outstanding performance.
• Low Maintenance and Wireless: Once installed, the Schlumpf Drive requires minimal upkeep. Thanks to its clever mechanics, there are no cables involved.
• Durable and High-Quality: Each part is hand-assembled and undergoes strict quality control to ensure a long lifespan.

Variants of the Schlumpf Drive on Our VELLO Bikes:

Speeddrive:

With a gear ratio of 1:1.65 or 1:1, the Speeddrive doubles the number of gears available to you. It can replace a double chainring in derailleur systems and is also compatible with belt drives. Whether you need more speed or flexibility on various terrains, the Speeddrive offers the perfect support.

Mountaindrive:

The Mountaindrive is ideal if you often face steep climbs or carry heavy loads. It reduces the gear ratio to 2.5:1, providing significantly more power with the same effort. Additionally, you have the standard 1:1 gear ratio available.

Your VELLO Bike with Schlumpf Drive

• On the VELLO Bike+ AUTOMATIC, the Schlumpf Drive provides a simple two-speed shifting system.
• On the VELLO Bike+ GEARS, it even doubles the number of gears from three to six—making your VELLO Bike even more versatile.

Thanks to the clever pedaling motion, you can easily shift gears, even while riding.
