KELLYS Tygon RS90: A powerful hardtail with a big battery for long and demanding rides

The KELLYS Tygon RS90 is one of the top sport e-bikes in the hardtail MTB category. It combines high performance, modern frame construction and an extremely long range thanks to an extra-large battery. It is designed for riders who want maximum efficiency on climbs, confidence on the terrain and the ability to cover dozens of kilometres without compromise.

Powerful Panasonic motor with 105 Nm of torque

At the heart of the Tygon RS90 is a powerful Panasonic GXM MaxxPro mid-motor that delivers up to 105Nm of torque. This gives the e-bike the power it needs for steep exits, technical passages and fast off-asphalt crossings. The motor is known for its responsive response, quiet operation and high reliability, which will be especially appreciated by sport-oriented riders.

820 Wh battery - range up to 200 km

One of the RS90's biggest draws is its integrated 820 Wh battery, which offers a range of 140 to 200 km, depending on the terrain, rider weight and selected assist mode. This makes the Tygon RS90 an ideal choice for day or even multi-day trips without the need for charging.

Lightweight and strong frame with precision welding

The Al 6061-T6 series aluminium alloy frame is manufactured using robotic technology to ensure maximum rigidity and durability. Soldered and reinforced joints give the bike the stability it needs, even at higher speeds or on rougher terrain. Hardtail construction also means efficient power transfer to the pedals and lower overall weight.

Air fork and confidence on the trails

Comfort on the trail is ensured by an air fork with around 130 mm of travel. It gives the rider confidence on fast descents and on rocky or rooty sections. Thanks to its modern geometry, the Tygon RS90 is stable even at higher speeds, while retaining its natural handling.

12-speed shifting and reliable braking

The e-bike is equipped with a 12-speed drivetrain that provides a wide gear range suitable for steep climbs and flats. Hydraulic disc brakes provide reliable performance even on longer descents. The Schwalbe Wicked Will tyres, on the other hand, provide sure grip in a variety of conditions.

Comfort and handling thanks to the dropper seatpost

The Tygon RS90 uses a telescopic dropper seatpost, which allows you to quickly lower the saddle in steep passages. This increases both safety and bike control, especially on technical trail sections. The seatpost has enough travel for advanced sport riding.

Connection to the Kellys Connect app

The e-bike supports the Kellys Connect smart app for system updates, ride data tracking and customized motor support options. This opens up room for further personalization based on riding style or fitness level.

Who is the KELLYS Tygon RS90 ideal for?

• sporty MTB riders who want a powerful hardtail without compromise
• bikers looking for long range and a reliable motor
• riders who prefer a lighter weight than full suspension models
• those who want a fast, efficient and versatile e-bike for off-road and forest trails

The KELLYS Tygon RS90 is a modern mountain e-bike for demanding riders who care about performance, long range and low weight. Thanks to a powerful Panasonic motor, a huge 820Wh battery and a solid frame, it offers great value for money. It's the perfect partner for long mountain tours, sports training and adrenaline-fuelled trails.

KELLYS BICYCLES s.r.o. now offers an extended warranty of 5 years. This extended warranty covers the frame of the e-bike and its claim when a manufacturing or material defect is proven to be the cause.
