Keep Riding the Bike You Already Love
Stop shopping for a new e-bike. Duo installs on your existing disc brake road or gravel bike, so you keep the fit, feel, handling and ride quality you already trust. No bulky conversion kits. No compromise on what makes your bike yours.
Lightweight Carbon Construction That Still Rides Like a Real Bike
At approximately 2.5 to 3 kg for the motor system, Duo delivers electric assistance in a lighter, more refined format than traditional e-bike setups. The matching front and rear carbon wheels are a premium wheelset, not an obvious conversion kit, so your bike stays responsive, balanced, and beautiful.
Assistance That Feels Natural
The integrated torque sensor reads how hard you're pedalling and delivers support that feels natural, never abrupt. Stay with faster friends, conquer hills, push through headwinds and extend your rides without the clunky feel of a heavy e-bike.
Electric When You Want It. Your Bike When You Don't
Duo installs and removes much like a standard wheelset. Use it for hill rides, longer weekends, group rides, commuting, or recovery days, then swap back to your regular setup whenever you want a fully unpowered ride.
