Blur the lines between road and trail with the Amperio Velocity GRX-E, a high-performance electric gravel bike for the dedicated rider.

The Velocity was born from a love of the long ride. Its creators were road cyclists who felt the magnetic pull of the unpaved path, the bridleway that branched off the main road, the forest track that promised adventure. They wanted the speed and efficiency of a road bike but with the versatility to leave the tarmac behind. The problem was that existing electric systems were often heavy and obtrusive, dulling the ride feel. They wanted assistance that felt like a natural extension of their own power, not a crude push.

Their search led them to the Fazua Evation system, a revolutionary motor and battery combination that is lightweight, compact, and can be completely removed from the bike, allowing you to ride it as a conventional, non-electric gravel bike. The power delivery is subtle and smooth, rewarding your effort rather than replacing it. We paired this groundbreaking system with a meticulously crafted carbon fibre frame, engineered for compliance on rough surfaces and stiffness for power transfer. To complete the masterpiece, we specified Shimano's electronic GRX Di2 groupset, offering flawless, lightning-fast shifting in any conditions.

This bike is the result of a relentless pursuit of perfection. It’s for the rider who loves the feeling of spinning along a quiet country lane as much as they love the crunch of gravel under their tyres. It’s a tool for exploration, a machine for epic all-day adventures, and a beautiful example of cutting-edge cycling technology.

Why It Matters

• A True 'Two-in-One' Bike: The entire Fazua motor and battery unit can be removed, transforming the Velocity into a lightweight, high-performance acoustic gravel bike.
• Featherlight Assistance: The Fazua system is one of the lightest on the market, preserving the nimble and responsive handling you expect from a premium gravel bike.
• Flawless Electronic Shifting: Shimano's GRX Di2 groupset provides perfect, reliable gear changes at the touch of a button, no matter the terrain.
• Engineered for Adventure: The full carbon frame and fork provide a comfortable, responsive ride with ample clearance for wide, grippy gravel tyres.

Imagine cresting a tough climb, the subtle assistance of the motor making it feel heroic. As you hit the rolling tarmac, you glide along with incredible efficiency. Then, you spot a promising track leading into the woods and dive in with total confidence, your bike handling the transition seamlessly. This is the boundless freedom the Velocity offers.
