In Autumn 2024, Ridley revolutionised the gravel bike market with the ASTR RS — a bike that quickly set the benchmark for off-road performance. Now, that benchmark is being raised again with the launch of the E-ASTR — Ridley’s second e-bike and the first electric evolution of the acclaimed ASTR platform.

The E-ASTR: Power Meets Purity

The E-ASTR is powered by the compact TQ HPR40 drive unit. Weighing just 1.2 kg for the motor and 1.42 kg for the battery, it offers the highest torque-to-weight ratio in its class. The result? A near-silent, natural-feeling ride that blends seamlessly into the classic gravel bike experience.

  • Up to 40 Nm of torque
  • 200W of additional power
  • 290Wh battery (with optional 160Wh range extender)
  • No drag, no awkward transitions — just smooth, natural assistance

True Gravel Geometry

Despite its electric heart, the E-ASTR remains 100% gravel:

  • 71.5° head angle for sharp, responsive handling
  • 74° seat angle for efficient power delivery
  • 75mm bottom bracket drop for high-speed stability
  • 425mm chainstays for a playful ride feel
  • Tire clearance up to 52mm for enhanced grip and comfort

This is a bike built for performance, not compromise.

E-Bikes Done Right

Ridley’s entry into the e-bike world is a deliberate move — driven by demand from riders who want a bit of support without losing the feeling of riding a traditional bike. The E-ASTR offers just that: subtle, balanced assistance that’s there when you need it and invisible when you don’t.

Following the success of the allroad E-GRIFN, the E-ASTR brings this electric philosophy to the pure gravel category. It’s built for those who want a ride that’s lighter, faster, and closer to the terrain.

What’s Next for Ridley?

Ridley confirms that other platforms will follow with electric variants — but choosing the ASTR as the first was no accident. It’s a performance icon, now electrified. The E-ASTR isn’t just an e-bike; it’s a benchmark built on a benchmark.
