The Altis vs Ventus adults comparison examines two emerging mid-range electric dirt bikes through verified power specifications and measured performance data. Data-driven comparison of two emerging mid-range electric dirt bikes for adults
The mid-range segment of electric dirt bikes for adults has become increasingly competitive, with manufacturers targeting the gap between entry-level lightweight bikes and premium full-power motocross machines. The Altis Sigma and Ventus One represent two distinct engineering approaches to this market segment: the Altis prioritizes voltage efficiency and smooth power delivery through a 98V electrical architecture, while the Ventus emphasizes raw peak power and lightweight agility with a 72V system capable of 28kW bursts. Both bikes occupy similar price points around $5,500-$5,800, but their performance characteristics, component choices, and real-world behavior differ measurably.
This comparison examines the quantifiable differences between these two electric dirt bikes for adults. Weight, power output, battery capacity, suspension design, and chassis geometry are not marketing claims—they are measurable specifications that determine how each bike performs on trails, tracks, and urban terrain. The Altis Sigma weighs approximately 190 lbs (86 kg) with a 3.4kWh battery pack, while the Ventus One weighs 152 lbs (69 kg) with a 3.6kWh battery. This 38-lb weight differential influences acceleration, handling, and rider fatigue. The analysis that follows is based on manufacturer specifications, third-party reviews, and documented performance testing.
Key considerations for altis vs ventus adults buyers and enthusiasts.
Direct specification comparison reveals the fundamental engineering differences between these two mid-range electric dirt bikes for adults. The Altis Sigma employs a higher voltage architecture (97.2V nominal) with a hairpin motor design rated for 20-22.5kW peak output. The Ventus One uses a 72V system with a Permanent Magnet Synchronous Motor (PMSM) capable of 20kW in mid-performance mode and 28kW in high-performance mode. These electrical system differences create distinct power delivery characteristics that affect rider experience.
| Specification | Altis Sigma | Ventus One (Plus) |
|---|---|---|
| Peak Power | 20-22.5 kW (27-30 hp) | 20-28 kW (27-38 hp) |
| Voltage System | 97.2V (98V class) | 72V |
| Battery Capacity | 35Ah Samsung 50S (3.4 kWh) | 50Ah Samsung 27100 (3.6 kWh) |
| Peak Torque | 533-601 Nm (sprocket dependent) | 390 Nm |
| Weight (with battery) | 185-194 lbs (84-88 kg) | 152 lbs (69 kg) |
| Top Speed | 70-80 mph (ideal conditions) | 80 mph (130 km/h) |

The specification table reveals that both bikes target similar performance envelopes but achieve them through different engineering paths. The Altis achieves higher torque figures through gearing and voltage, while the Ventus achieves higher peak power through amperage. The 38-lb weight difference represents approximately 25% more mass on the Altis, which affects every aspect of dynamic performance.
The fundamental electrical architecture difference between these bikes determines their power delivery characteristics. The Altis Sigma's 98V system operates at higher voltage with lower current draw to achieve its rated power output. Higher voltage systems generally offer improved efficiency and reduced heat generation under sustained load, as power losses in electrical systems are proportional to current squared (I²R losses). This means the Altis can theoretically maintain consistent power output for longer periods without thermal throttling.
The Ventus One's 72V system achieves its 28kW peak power through higher amperage draw. This approach delivers more aggressive initial acceleration and higher peak torque at the motor shaft, but generates more heat during sustained high-power operation. Reviews consistently describe the Ventus power delivery as "raw" and "aggressive," while the Altis is characterized as "smooth" and "controllable." These are not subjective preferences—they reflect measurable differences in power curve shape and throttle response mapping.
The Altis Sigma's claimed torque figures of 533-601 Nm are exceptionally high for this class, achieved through aggressive gearing ratios. The standard model uses a 39-tooth rear sprocket, while the MX variant uses a 44-tooth sprocket to maximize low-end torque multiplication. This gearing strategy prioritizes acceleration and hill-climbing ability over top speed. The Ventus One's 390 Nm torque rating is lower at the motor, but the bike's 38-lb weight advantage means the torque-to-weight ratio remains competitive.
In practical terms, the Altis will feel stronger pulling away from stops and climbing steep grades. The Ventus will feel lighter and more responsive to throttle inputs, particularly in technical terrain where quick direction changes are required. For riders prioritizing smooth power for trail riding, the Altis has an advantage. For riders seeking maximum agility and playfulness, the Ventus offers superior power-to-weight dynamics. This analysis helps riders narrow their altis vs ventus adults choices based on real-world data.
Battery capacity determines theoretical range, but real-world range depends on power consumption, which is influenced by weight, aerodynamics, and riding style. The Altis Sigma's 3.4kWh Samsung 50S battery pack is slightly smaller than the Ventus One's 3.6kWh Samsung 27100 pack—a difference of approximately 6%. However, the Altis's higher voltage architecture may extract energy more efficiently under moderate load conditions.
Claimed range figures show the Ventus One achieving up to 70 miles under WLTP testing conditions (40 km/h constant speed), compared to the Altis Sigma's 40-50 mile typical range with potential for 100 miles in ideal conditions. These manufacturer claims must be contextualized: WLTP testing at 40 km/h represents unrealistically gentle riding for most electric dirt bike for adults use cases. Real-world aggressive trail riding typically yields 30-50% of claimed range figures.
Based on third-party testing and user reports, realistic range expectations are:
The Ventus One's lighter weight and slightly larger battery provide a measurable range advantage in real-world conditions, particularly when ridden at moderate power levels.
The Altis Sigma offers a significant advantage in charge time: 3 hours for a full charge, with 20-80% charging achievable in approximately 2 hours. The Ventus One requires 4.2 hours for a full charge. This 1.2-hour difference becomes meaningful for riders who need to recharge between sessions or those with limited charging windows. For riders who charge overnight, the difference is negligible. For riders who want to ride multiple sessions in a single day, the Altis's faster charging is a practical advantage.
The 38-lb weight difference between the Altis Sigma (190 lbs) and Ventus One (152 lbs) represents the single most significant performance differentiator between these bikes. Weight affects acceleration, braking, cornering, and rider fatigue. A 25% weight penalty requires 25% more energy to accelerate to the same speed, assuming identical power outputs. It also increases braking distances and requires more physical effort to maneuver at low speeds.
The Ventus One's lightweight construction makes it significantly more agile in tight technical terrain. Riders can flick the bike through switchbacks, lift the front wheel over obstacles, and make quick direction corrections with minimal effort. The Altis Sigma's additional weight provides stability at speed and better traction on loose surfaces (more weight on the rear tire improves grip), but requires more deliberate inputs and planning in technical sections.
For context on how weight affects handling across different bike categories, see our detailed analysis of lightweight vs heavy-duty electric dirt bikes. These performance characteristics directly impact the altis vs ventus adults experience on the trail.
Both bikes use centrally-mounted battery packs to optimize weight distribution, but the Altis's heavier overall mass raises its effective center of gravity. This affects how quickly the bike transitions from side to side and how much effort is required to hold the bike upright when stopped on uneven terrain. Shorter riders (under 5'9") may find the Ventus One easier to manage when dabbing feet or recovering from off-balance situations.
Suspension design represents one of the most controversial aspects of the Altis Sigma. The bike uses adjustable air spring suspension with 200mm of front travel and 85mm of rear travel amplified through a linkage system. Air suspension offers the advantage of easy preload adjustment without changing springs, but reviews consistently note that the Altis suspension feels soft and bottoms easily on aggressive jumps and rough terrain. This is a documented limitation, not a subjective complaint.
The Ventus One, particularly the Plus model, uses FastAce front forks and RFloxa rear suspension. These oil-damped units receive consistent praise for their tunability and performance. The RFloxa suspension on the Plus model is specifically highlighted in reviews as providing excellent control and a smooth ride even at high speeds. For riders who prioritize suspension performance and plan to ride aggressively, the Ventus One Plus offers a measurable advantage.
| Suspension Metric | Altis Sigma | Ventus One Plus |
|---|---|---|
| Front Suspension | Adjustable air spring (200mm) | FastAce/RFloxa oil-damped |
| Rear Suspension | 85mm + linkage amplification | RFloxa oil-damped (Plus) |
| Adjustability | Air pressure (preload) | Compression, rebound, preload |
| Bottoming Resistance | Moderate (noted limitation) | High (praised in reviews) |
| Best Use Case | Trail riding, moderate terrain | Aggressive riding, jumps, rough terrain |
The suspension difference becomes critical for riders who plan to jump their bikes or ride aggressive motocross-style terrain. The Altis Sigma's suspension is adequate for trail riding and moderate off-road use but shows its limitations when pushed hard. The Ventus One Plus's suspension can handle more aggressive riding styles without compromising control or safety.
Both bikes feature hydraulic disc brakes with regenerative braking systems offering five adjustable modes. The Altis Sigma uses 4-piston calipers with heavy-duty DOT-spec rotors. The Ventus One standard model initially received criticism for brake performance, but newer models (particularly the Plus variant) have upgraded to DOT fluid brakes that receive high praise for stopping power.
Regenerative braking effectiveness depends on battery state of charge and motor controller programming. Both bikes can recover energy during deceleration, but the actual energy recovery percentage varies based on riding conditions. Descending long grades can recover 8-12% of battery capacity on either bike, providing a modest range extension. The primary benefit of regenerative braking is reduced wear on mechanical brakes rather than significant range improvement. Understanding these metrics is fundamental to making an informed altis vs ventus adults decision.
Reviews indicate that the Altis Sigma's brakes offer consistent, progressive feel with good modulation. The Ventus One Plus's upgraded brakes are described as having excellent stopping power with strong initial bite. For riders prioritizing maximum braking force (aggressive downhill riding, high-speed trail riding), the Ventus One Plus has an edge. For riders who prefer smoother, more progressive braking (technical terrain, novice riders), the Altis Sigma's setup may feel more confidence-inspiring.

The optimal choice between the Altis Sigma and Ventus One depends on intended use case, rider priorities, and physical characteristics. This section provides data-driven recommendations based on specific rider profiles.
Rider height and weight affect bike choice. Shorter riders (under 5'9") may find the Ventus One's lighter weight easier to manage when stopped or maneuvering at low speeds. Taller, heavier riders (over 200 lbs) may appreciate the Altis Sigma's more substantial chassis and higher weight capacity. Both bikes can accommodate a range of rider sizes, but the weight difference affects the physical effort required to control the bike.
The Altis Sigma and Ventus One represent two valid engineering approaches to the mid-range electric dirt bike for adults segment. Neither is objectively superior—they optimize for different priorities. The Altis Sigma prioritizes smooth power delivery, higher voltage efficiency, faster charging, and stability. The Ventus One prioritizes lightweight agility, raw peak power, superior suspension (Plus model), and maneuverability.
The 38-lb weight difference is the most significant performance differentiator. This weight penalty on the Altis provides stability and traction advantages but sacrifices agility and ease of handling. The Ventus One's lighter weight makes it more playful and responsive but less planted at high speeds. The suspension difference is equally important: the Altis's air suspension is adequate for moderate riding but shows limitations when pushed hard, while the Ventus One Plus's RFloxa suspension handles aggressive riding with confidence.
For riders who cannot decide between these two bikes, the decision often comes down to a test ride. The power delivery difference (smooth vs aggressive) and weight difference (stable vs agile) are immediately apparent within the first five minutes of riding. Trust the data, but verify with personal experience when possible.
