The 2027 Atlis SIGMA MX in Black is a lightweight, electric off-road motorcycle built around a 97.2V 35Ah Samsung 50S battery (3.4 kWh) and an air-cooled powertrain with 25kW peak input (33.5 HP). With a listed top speed of 68 mph and 670Nm of torque (44T sprocket), it’s set up for quick acceleration and strong drive out of corners. A 3.5" display keeps key ride info in view, while 5 levels of adjustable regenerative braking let you tune deceleration feel. Suspension travel and ground clearance round out a purpose-built trail-and-track package.
25kW peak electric drive
The SIGMA MX pairs a 97.2V Samsung 50S battery (3.4 kWh) with a 450 phase-amp controller and an air-cooled system rated at 25kW peak input (33.5 HP). Atlis lists 670Nm of torque with a 44T sprocket and a top speed of 68 mph, giving this electric platform the kind of punch and speed that fits aggressive off-road riding.
Suspension travel and clearance
Built for uneven terrain, the chassis combines a 220 mm dual spring fork up front with an 85 mm adjustable rear suspension. Ground clearance is listed at 12.5", helping the bike manage ruts, rocks, and trail obstacles. A 51" wheelbase and 19" wheels complete a compact off-road stance designed around control and maneuverability.
Regenerative braking control
Dial in how the bike slows down with 5 levels of adjustable regenerative braking. For conventional braking, the SIGMA MX uses 4-piston hydraulic brakes with a 260 mm front rotor and 220 mm rear rotor. A 3.5" display provides at-a-glance visibility for ride information, keeping the cockpit simple and focused.
Electric powertrain and charging
At the core of the 2027 SIGMA MX is a 97.2V 35Ah Samsung 50S battery with a stated capacity of 3.4 kWh, feeding a 450 phase-amp controller. Atlis rates the air-cooled system at 25kW peak input (33.5 HP) and lists 670Nm of torque with a 44T sprocket, along with a listed top speed of 68 mph.
Charging time is listed as 80% in 2 hours and 100% in 3 hours, making it straightforward to top up between rides or sessions.
Chassis, suspension, and fit
The SIGMA MX is sized and set up for off-road use with a 34.5" seat height, 12.5" of ground clearance, and a 51" wheelbase. It rides on 19" wheels and has a listed weight of 195 lbs, supporting a nimble feel on tight trails and technical sections.
Suspension components include a 220 mm dual spring fork up front and an 85 mm adjustable rear suspension, giving you a baseline setup that can be adapted to terrain and preference.
Braking and rider controls
For stopping power, the SIGMA MX uses 4-piston hydraulic brakes with a 260 mm front rotor and 220 mm rear rotor. That mechanical braking is paired with adjustable regenerative braking, offering 5 levels to tune how much the bike slows when you roll off the throttle.
