With the Performance Line SX motor - 55 Nm torque at 600 W maximum power - and the Compact Tube 400 battery, the Argon GX SWIFT not only uses by far the lightest system in the Bosch line-up, above all the new system impresses with a natural feel of its power delivery. The motors installed in most eMTB and touring e-bikes are significantly larger and heavier than the SX drive on the Argon GX SWIFT. These motors push you forward with ample torque as soon as a pedal stroke is registered. Once the maximum speed of 25 km/h is reached, these drives cut out in an instant, which subjectively feels like the bike is slowing down. With the exclusive sprint technology featured by the Bosch Performance Line SX drive, however, the power output of the Argon GX SWIFT is also dependent on the cadence, which makes for a much sportier and more natural riding experience. The full motor power of 600 W is only delivered at a high cadence. When the limit is reached, the power gently decreases towards the top. The Argon GX SWIFT can therefore be ridden at speeds well above the assisted 25 km/h threshold without any sensation of breaking.
Fast, powerful, efficient and with just the right amount of comfort, the Argon GX SWIFT takes gravel adventures to a whole new level. It gives riders the freedom to explore even further, ride faster, attack harder, experience a more dynamic ride for more fun and tackle long climbs with a smile.
Geometry
The Argon GX SWIFT largely adopts the proven, balanced geometry of our regular Argon GX gravel bike. A relatively long top tube and reach ensure sportiness, efficiency and speed. The height of the front, the stack, has been optimized for comfort to ensure long, fatigue-free riding and maximum bike control off-road. A slack steering angle and a longer rear end increase smoothness and riding stability on unpaved paths and trails. We have designed the Argon GX SWIFT with an adaptive geometry that takes into account weight and proportion factors for different body sizes. As the length and height of the main frame increases, the seat angle becomes slacker for larger frames, while the steering angle becomes steeper. This ensures that the character of the bike remains the same in every size. The Argon GX is available in 6 frame sizes, from XS to XXL, suitable for riders from 160 cm to 208 cm.
Frame design
Following NICOLAI tradition, the painstakingly crafted 7020 T6 aluminum frame is manufactured entirely in-house. With its hollow milled HMT yokes, rectangular rear end stays and thru-axle dropouts to Boost standard (UDH-ready), it boasts excellent stiffness for loss-free, direct propulsion and a highly precise handling. A rather short seat tube in relation to the frame size allows for a longer seatpost extension, which then reduces vibrations and increases comfort thanks to its flex. The Argon GX SWIFT is designed with a strong focus on durability and longevity. Certified according to ASTM category 2, the permissible total weight of rider and bike is an impressive 140 kg, with a manufacturer's warranty of 5 years.
Tire clearance
With the Argon GX SWIFT, tires up to a width of 47 mm on 28 inch wheels or 51 mm on 27.5 inch wheels can be fitted, putting it at the upper end of the gravel spectrum. Wide tires not only provide comfort dsuspension and damping on gravel and uneven ground, they are also an important factor for the bike's off-road capabilities. The wider the tires, the lower the air pressure that you can run, which ensures a larger contact surface on rough terrain and therefore more grip, traction and safety.
Verdict
The Argon GX SWIFT offers a well balanced, versatile geometry, low weight and a high level of comfort. One major strength is the natural riding feel thanks to a dynamic power delivery depending on the cadence. Whether for epic explorations on unknown trails, fast laps, KOM, bikepacking adventures or the daily commute through urban environments - the Argon GX SWIFT offers a vast range of uses and an outstanding riding experience that redefines the capabilities of a gravel bike. The Argon GX SWIFT is the ideal gravel e-bike for you if large motors are too heavy and unsporty for you - but a minimal-assist drive on the other hand provides too little power and range.
