Orbea Denna M20I e-gravel bike review

Jul 2025

The Orbea Denna M20I is an awesome gravel bike, a gravel bike that just happens to be paired up with an intuitive, powerful, efficient, responsive and impressively smooth motor system. Yep… It’s a good ‘un, and its frugal battery usage means that range anxiety isn’t an issue. The only thing you’ll probably need to allow for is a tyre upgrade for anything other than the driest, smoothest trail.
