BIKE review of the Kona El Kahuna
The 2026 Kona El Kahuna is a well-designed e-trekking hardtail with a distinct outdoor feel. The high-quality RockShox fork, dropper post and knobby tyres remain true to Kona’s MTB heritage. The Bosch Connect Module and the comprehensive range of travel features are real plus points. However, the price of 4,999 euros for a bike with a rather outdated e-system is rather steep. The US price of 3,499 dollars is a completely different ball game. – Adrian Kaether, Test & Technology Editor
The El Kahuna: A capable all-rounder
Kona clearly positions the El Kahuna as the one bike to rule them all: A hardtail frame made from Kona 6061 aluminium is combined with 29-inch wheels, 100 millimetres of front suspension travel and a full range of travel accessories, including a luggage rack with a 25-kilo load capacity, mudguards and lights. This concept is familiar from the European SUV e-bike and trekking segment – Kona is now giving the whole thing its own North American twist.
Four frame sizes (S to XL), each with tailored reach and stack values as well as different dropper post travel lengths (100 to 150 mm), point to a well-thought-out geometry.
Drive system and battery: Tried and tested, but no longer brand new
At the heart of the bike is the Bosch Performance Line motor – though it’s still the old version. Even before Eurobike 2025, Bosch had unveiled a successor, which is often combined with the lighter 600 and 800 battery packs. The older motor in the Kona still has to make do with the Bosch PowerTube 625 Wh battery, which is slightly heavier. The battery is neatly integrated into the down tube and can be removed using a key. A nice touch: for the EU market, a Bosch PowerMore 250 Wh range extender is also included – all frame sizes are said to be compatible with it.
The bike is operated via the Bosch Intuvia 100 Smart System display (though this is also still the old model) with a 2.5-inch screen, as well as a mini remote with a system controller mounted on the top tube and the Bosch Connect Module. With the Flow+ subscription (available at an additional cost), you can access GPS tracking, motion alerts and mobile data connectivity.
Chassis and equipment
The RockShox Recon Gold RL suspension fork is a real highlight: with 100 mm of travel and a Debonair air spring, it’s a delightfully high-quality choice for this class of bike, on a par with the better Suntour forks or Fox’s AWL forks. This sets the El Kahuna apart from the majority of trekking e-bikes. The TranzX dropper post is also noteworthy – by no means a given on an e-trekking bike and a clear nod to off-road-minded buyers. However, the dropper post must be activated manually whilst seated, rather than via an ergonomic remote lever.
The Schwalbe G-One Allround TLE 29×2.25" in a tubeless-ready version with Double Defense insert and Raceguard fits in with the all-round concept. According to Kona, a maximum size of 29×2.4" would be possible, albeit with some compromises, provided no mudguards are fitted. However, corners have been cut with the MicroShift Advent X 10-speed rear derailleur and 11–48T cassette. Whilst functional and good value for money, this feels below par on a bike costing just under 5,000 euros. The same applies to the Tektro Gemini brakes. They’re solid, but the competition often offers better value for money here. The Kona also lacks a chain guard. The Lezyne lights at the front and rear, on the other hand, are top-notch.
