Joyful adventure
the best adventures never end; thereâs always something exciting just around the corner or over the next hill.

Rc tune: full torque and balanced power
rider synergy (rs gen2) is central to denna's go-anywhere capabilities. Weight, power and simplicity plus a best-in-class battery range means you can rewrite your idea of what is possible.

50c tire clearance
denna has clearance for up to 50c tires, so you can even fit many mountain bike tires for maximum grip and comfort.

420 wh battery
our 420 wh battery offers more power in a lighter, smaller package. Thanks to the energy savings from our rs gen2 rc firmware, the average rider will get up to 3500m of climbing from this battery.

Frame absorption points
specifically shaping the frame at key points allows controlled vertical flex to absorb bumps and chatter coming from rougher paths. The tube shapes here resist lateral flex, meaning we don't compromise denna's pedalling efficiency or handling.
