Thron² 6.9

Geometry Specification

More than just trails

  • Super powerful and dynamic e-motor with record-breaking integrated range

    The efficient Bosch Performance CX e-drive (Gen. 4) supports your ride up to 25 km/h with powerful 85 Nm. The strongest e-motor of Bosch is perfectly integrated, the THRON² rides well-balanced. In eMTB mode, the motor support adjusts automatically to your riding power. The new 750 Wh battery (smart system) delivers endless tail fun. The battery is integrated into the down tube, yet removable for charging. On top, you get the new Kiox 300 display with the new LED remote.

  • Optimized kinematics for strong progression

    With the upgrade of our well-known F.O.L.D. kinematics, your THRON² 6.9 is ready for even more fun on your tours. We kept the well-liked sensitivity of the F.O.L.D. but changed the positioning of our kinematics within the frame for strong bottom-out resistance. The characteristics are completely progressive which results in a chassis that offers a lot of stability making you feel safe on any terrain. Especially e-mountain bikes with their additional weight of motor and battery benefit from more progression. This allows you to handle any trail while the chassis still provides comfort for long laps. Furthermore, the lower standover of the THRON² 6.9 gives you more space to play on the trail.

  • Diverse usage

    From trail tours through alpine terrain to your daily commute and bikepacking: anything is possible with the THRON². With certain changes to the build, you can add various features to your THRON² – depending on where your e-MTB tour is going. Furthermore, the specially developed C.I.S. (Cockpit Integration Solution) design ensures a clean cockpit and constantly seamless shifting and braking. All cables run from the handlebar into the stem and through the headset into the frame. Additionally, a USB C port on the top tube gives you the opportunity to charge your devices.
