8kW Segmented Motor
The Delta S uses an 8kW peak segmented motor rated at 10.7HP peak output. Because electric torque arrives instantly, the bike feels responsive from low speed and helps riders build confidence without managing gears or a clutch.

The Delta S pairs off-road spring-air suspension with a 17/14 wheel setup, 10.8 inches of ground clearance, and a compact 46.8 inch wheelbase. The result is a bike that stays approachable while still giving riders room to explore rougher terrain.
The 72V30Ah LG Power-Pack battery gives the Delta S a 2160Wh energy capacity for repeatable off-road sessions. Charging from 20% to 80% takes about 3 hours, helping riders get back out without a long wait.
A color display keeps important ride data visible at a glance, including speed-level information riders can use to match the bike to the riding area, skill level, and conditions.
Off-road disc braking gives the Delta S the control needed for quick electric acceleration, tight practice areas, and technical sections where predictable speed management matters.
The forged aluminum alloy frame helps keep the Delta S tough without making it feel oversized. With a 31.8 inch seat height, the bike is positioned for riders who want a smaller electric platform with serious capability.
The Altis Delta S is made for riders who want electric performance in a smaller, confidence-building package. It keeps the ride simple: instant power, no shifting, no fuel, and three selectable speed levels that let riders match the bike to the space, terrain, and comfort level.
With a 72V30Ah LG Power-Pack battery, an 8kW peak segmented motor, 273 Nm of rear-wheel torque, and a forged aluminum alloy frame, the Delta S is more than a beginner-friendly electric pit bike. It is a capable off-road machine designed for weekend sessions, practice laps, and riders who want less noise with more seat time.
The 17/14 wheel setup, 10.8 inches of ground clearance, spring-air suspension, color display, and off-road disc brake help the Delta S feel controlled and ready on dirt. Whether the goal is learning the basics or pushing harder on familiar trails, this bike keeps the focus on riding.

Battery life varies depending on usage, terrain, and riding style. Most sigma performance bikes are designed to last several hours on a full charge under normal conditions.
The professional cycling bike design of the Sigma includes advanced engineering, durable materials, and high-performance components that support long rides and challenging terrains.
While the Sigma can handle smooth road surfaces, it is not designed as a sigma road bike or a speed road bike. It is primarily built for off-road performance, featuring thick tires, strong suspension, and a durable frame for rough terrain.
The Altis Sigma bike typically includes:
- High-performance motor
- Long-lasting battery
- Durable frame design
- Advanced braking system
Electric dirt bikes exceed gas bike performance in most metrics. Instant torque delivery from 0 RPM provides superior acceleration. Consistent power delivery eliminates powerband limitations. Lower center of gravity improves handling. Only very high-performance gas bikes exceed our top speeds.
The Altis Sigma bike is a high-performance electric and off-road capable bike designed for riders who want power, speed, and durability. It is built for both adventure and performance riding.
