KONA EL KAHUNA | A Practical E-MTB for "Everyday and Mountains"
A versatile E-MTB that seamlessly connects city riding, forest roads, and weekend trails, all with one bike.
The "EL KAHUNA" is an all-round E-MTB based on KONA's popular hardtail MTB "Kahuna," combined with a Shimano electric assist unit.
It's a bike that naturally integrates into your lifestyle, from daily commutes and city rides to weekend trail rides and outdoor adventures.
Equipped with a Shimano DU-E6180 drive unit and a large-capacity 504Wh battery, it provides comfortable riding even on steep hills and long distances. It combines the nimble ride of a hardtail with the added power of an E-BIKE.
The combination of a 100mm travel front suspension and 29-inch WTB wheels with Trail Boss tires ensures reliable off-road capability, from urban bumps to forest roads.
This versatile E-MTB perfectly answers the desire to "use it for commuting, but also go to the mountains on weekends."
Features
- Electric assist specification with Shimano DU-E6180 drive unit
- Built-in 504Wh large-capacity battery for long rides
- SC-E7000 display for easy viewing and operation
- 100mm travel suspension ensures comfortable off-road capability
- Shimano disc brakes provide stable braking performance
- 29-inch WTB rims and Trail Boss 2.25-inch tires for high grip and off-road capability
- Versatile design suitable for "all daily activities" such as commuting, shopping, and forest road riding
- Lightweight handling and ease of use characteristic of a hardtail

This E-MTB is incredibly practical, combining the nimble feel of a hardtail with the powerful assistance of an electric motor.
With the stability of 29-inch tires, you can ride through urban bumps and rough roads without worry, and it has the versatility to take you directly onto forest roads and trails on weekends.
The natural assist of the Shimano unit is also a highlight, allowing you to ride with a feeling that's "not too E-BIKE-like." I believe this model is an excellent match for those who primarily commute and use their bike for daily tasks but also want to enjoy mountain riding on weekends.
This is a bike we recommend for those who want to balance "easy transportation" with "freedom for play."
