Enviolo hub gears
Shifting gears is part of cycling. But Enviolo can do more - and better. Enviolo Automatic offers a new way of shifting: intelligent, efficient, completely seamless and simply fun.
Perfect pedaling - always ride in the optimum gear
Feel like you're flying or gliding smoothly. Be the first at the traffic lights or enjoy a relaxed ride at a constant speed - whether commuter or cargo e-bike.
No distractions - free your attention
Enviolo Automatic is a "set it once and forget it" system that adapts to you - choose your preferred speed and off you go. Focus on your ride in busy cities, relaxed tours in the countryside or riding with children.
Less maintenance - fewer workshop visits
Enviolo Automatic is completely enclosed and ready for any weather. It requires no oil changes and ensures less effort and maintenance, especially in combination with a belt drive.
Connected
Easy to configure and update with the Enviolo Automatic app.
Versatile
310-380 % gear ratio range - ideal for any ride and environment.
Efficient
Riding in the optimum gear means less stress for you and your engine.
Safe
Your attention remains free for balance and surroundings.
Modern
Stylish and innovative, for fewer cables and minimalist frames.
The CVP technology
Continuously variable planetary CVP technology is at the heart of Enviolo's bicycle gears. The hub contains rotating balls that allow an unlimited number of gear ratios across its gear range. Between the input power from the pedals via the ring on the right. And output power from the ring on the left to the wheel.
A specially developed oil in the hub shell ensures effortless shifting from one gear ratio to the next. This makes shifting under load and pedaling child's play. The whole thing is controlled by a manual or automatic twist grip, which tilts the rotating balls and thus changes the gear ratio. All Enviolo hubs offer the same advantages: simplicity, resilience, no maintenance and low noise.
