What Is The Vello Sub The Lightest E-Cargo Bike Ever Built?

The Vello Sub is acclaimed as the lightest full-sized e-cargo bike ever built, weighing as little as 24 kg in its titanium variant while supporting a total load of up to 210 kg. Its minimalist design, high-end components including a Bosch Cargo Performance Line motor, and folding capabilities make it a game-changer for urban cargo transport, combining exceptional portability, power, and versatility in a sleek package.

What materials and frame design make the Vello Sub the lightest e-cargo bike?

The Vello Sub achieves its ultralight status primarily through the use of premium titanium for its flagship model, weighing approximately 24 kg (53 lbs). The frame employs minimalist, stripped-down design principles, removing all excess weight while retaining structural integrity to bear heavy loads safely. A chromoly steel variant is also available at a slightly heavier 28 kg. The bike features a sturdy yet lightweight longtail frame optimized for cargo distribution, with a low center of gravity that enhances balance and handling.

How powerful is the Vello Sub’s motor, and what battery capacity supports it?

Equipped with the latest Bosch Cargo Performance Line motor rated at 600W (250W nominal), the Vello Sub delivers a robust 85 Nm of torque, effortlessly powering heavy loads and quick acceleration. Power is supplied by dual 545 Wh Bosch batteries, which combined provide an impressive range of up to 250 km (155 miles) on a single charge, making it suitable for long urban trips or extended errands. The system is intelligently managed via the Bosch Smart System interface with remote control and smartphone app integration.

What is the cargo capacity and load management of the Vello Sub?

The Vello Sub is engineered to carry up to 210 kg (463 lbs) of combined rider, cargo, and passengers. Its longtail frame supports two child seats or extensive cargo loads, enhanced by an ultra-stiff rear rack designed for stability under weight. The bike features wide 20” Schwalbe tires which maintain a low center of gravity and provide excellent grip and safety whether empty or loaded. Tool-free, quick-release accessory mounts via the MIK-HD safety system allow easy switching of cargo baskets and child seats.

How does the compact size and foldable features benefit urban riders?

Measuring a standard length of 180 cm (70.9 in), the Vello Sub offers the cargo space and riding stability expected of larger cargo bikes but in a much more compact footprint. Its handlebars collapse 90 degrees, pedals fold, and height-adjustable front stem and seat post permit storage width reduction to just 29 cm, ideal for apartment storage or fitting inside public transport and small car trunks. This design optimizes urban mobility and minimizes storage hassles.

Which drivetrain and braking technologies are integrated into the Vello Sub?

The drivetrain relies on a low-maintenance Gates Carbon belt drive paired with a smooth Enviolo internal variable gear hub offering a 380% gear range and stepless shifting, even under load. This combination ensures quiet operation with minimal upkeep. Stopping power comes from four-piston Magura MT-4 hydraulic disc brakes, reputed for strong, reliable performance under heavy cargo conditions, supplemented by integrated rear brake lights for enhanced visibility.

What user-centric features and accessory systems come standard or optional?

The Vello Sub is designed with rider convenience foremost, featuring an LCD cockpit with smartphone mount, Bosch remote control, GPS tracking, and customizable ride modes via the eBike Flow app. Accessories mount tool-free using the MIK and MIK-HD systems. Integrated Supernova front and rear lights, a sturdy double-leg kickstand, and weather-protected components enhance safety and practicality, alongside adjustable ergonomics for rider comfort.

How does the Vello Sub maintain strength and safety despite its light weight?

Despite shedding weight, the Vello Sub passes rigorous EFBE-TRI-Test® certifications and load tests to withstand everyday cargo stresses up to 210 kg safely. Titanium’s superior strength-to-weight ratio and precision engineering ensure frame resilience without bulk. A low center of gravity and wide tires contribute to exceptional balance on the road. The bike’s suspension fork and advanced brakes complement the structural safety, making the light build uncompromisingly robust.

What innovative engineering solutions contribute to its efficiency and versatility?

Innovation lies in the minimalist design ethos marrying ultralight materials with modularity. The MIK-HD system allows effortless accessory swaps without tools, while the dual-battery setup enables extensive range coverage without heavy single packs. Electronic integration through the Bosch Smart System and eBike Flow app allows over-the-air upgrades and personalized riding modes. Foldability and compactness address urban storage and transport challenges typically unmet by larger cargo bikes.

How customizable is the Vello Sub for diverse cargo and passenger needs?

The Vello Sub supports a wide array of child seats, cargo baskets, panniers, and footboards, all mountable via standardized MIK and MIK-HD interfaces. Adjustable handlebars and seat posts cater to rider size and style preferences. The app-controlled motor modes enable riders to dial in assistance levels based on cargo weight or terrain demands, enhancing usability across lifestyles—whether running errands, school runs, or weekend adventures.

What key considerations should potential buyers have before purchasing the Vello Sub?

Prospective buyers should assess their typical load requirements and commuting distances to ensure the dual Bosch batteries and 600W motor meet their needs. While the titanium model offers the weight advantage, the steel variant balances a lower price with slightly more weight. Consider storage constraints and transport method, as Vello Sub’s compact fold is highly advantageous. Evaluate accessory needs and app integration preferences, and confirm local regulations for e-cargo bike specifications. Warranty coverage and customer support should factor into the decision.
