BOGOF - That's right, Buy One Get One Free. What's better than One, of course, TWO! - while riding with your best mate in style.

You can mix and match any size of these 2 selected EUNORAU models. The Defender S and Fat-HS.

Get two of the same bike or one of each. You cover any terrain in style!

Meet the new Eunorau Defender-S—an electric mountain bike built for those who demand resilience, versatility, and performance. Whether you’re navigating rugged trails, commuting through town, or simply looking for an ebike that won’t back down from any challenge, this is the ride for you.

The Defender-S combines a sturdy, ready-for-action build with 2 motors front/Back that you can independently switch between them or both with intuitive handling and modern styling. From the moment you hop on, it delivers a confident, balanced ride. Its design invites you to push further—long weekends away from paved paths, spontaneous off-road escapes, or daily rides with extra gear in tow.

Everything about the Defender-S is geared toward reliability and freedom. It’s designed to let you focus on the ride—enjoying the trail, exploring the city, or simply cruising with peace of mind—without worrying about what comes next.

Ready to take on the road less traveled? The Defender-S is your dependable partner in adventure.
