Peak Power and Motor Performance
When comparing powertrains, electric motorcycle battery voltage plays a crucial role in sustained performance, and the biggest difference between the two platforms is the Sigma’s higher-voltage architecture. The 2026 Altis Sigma high-output configuration is advertised with peak power up to 25.0 kW (34 HP), while some earlier versions or different configurations have been listed around 22.0 kW.
Altis markets the Sigma’s motor as using a high-efficiency, hairpin-style stator design. This design replaces traditional round copper wire windings with flat, rectangular copper bars. This design can improve copper fill density and reduce electrical resistance compared with traditional round-wire windings, potentially improving efficiency and thermal performance during sustained high-load riding. Under prolonged high-load riding conditions such as steep climbs or loose terrain, the Sigma’s higher-voltage architecture is designed to reduce current demand and maintain consistent performance.
The E Ride Pro SS 3.0 uses a highly refined, conventional 72V motor layout delivering approximately 15.8kW peak power. While 15.8kW is incredibly punchy for a lightweight machine, it lacks the top-end pull of the Sigma. In sustained high-load conditions, the higher-voltage Altis platform can offer efficiency advantages because it requires less current to deliver similar power output.
Top Speed Comparison: Speedometer vs. GPS Velocity
On flat, dry pavement, the E Ride Pro SS 3.0 typically reaches around 60–62 mph depending on rider weight, terrain, battery condition, and setup. While speedometers on the SS 3.0 may read slightly higher due to factory tire diameter calculations, GPS-tested speeds are generally around the 60–62 mph range depending on rider weight, battery condition, and riding conditions.
Standard 19-inch wheel versions of the Sigma have been reported to reach 70–80+ mph on the speedometer, with GPS-tested speeds around 64–70 mph depending on configuration. Because the high-voltage system runs cooler and maintains performance during sustained high-load riding, according to owner reports, the Sigma offers comfortable performance headroom for high-speed off-road transits or high-speed fire roads.
Torque Delivery and Throttle Modulation
Raw power is only as good as its control, and this is where these two bikes ride differently.
Some riders report that the SS 3.0’s factory throttle mapping can feel aggressive for beginners, especially in Sport mode. However, the bike’s throttle response is adjustable via the manufacturer’s app, allowing riders to customize the power curve to their preference. The bike is exceptionally snappy and responsive, which experienced riders appreciate, but it requires highly disciplined wrist control on slippery singletracks.
The Altis Sigma delivers its torque through a smooth, well-controlled power curve that balances accessibility with high-performance output. According to owner reports, the 2026 model’s 450 phase amp controller provides a linear throttle response that helps maintain traction on slippery surfaces while still delivering aggressive acceleration when needed.
Additionally, the Sigma standard edition features four distinct speed modes (Eco, Normal, Sport, and Race) and a dedicated reverse button. The reverse button is a massive convenience when maneuvering the bike out of deep mud or a tight ditch on a machine that weighs nearly 200 pounds.
Drivetrain Battle: Belt Drive Simplicity vs. Chain Drive Performance
The choice of drivetrain heavily dictates routine electric motorcycle maintenance, long-term running costs, and the acoustic footprint of each bike.

E Ride Pro SS 3.0 Hybrid Belt/Chain Drive System
The E Ride Pro SS 3.0 uses a belt-driven primary stage (from motor to intermediate sprocket) combined with a final chain drive (from sprocket to rear wheel). This hybrid design offers partial maintenance benefits:
- Partial Maintenance Reduction: The belt-driven primary stage reduces some drivetrain wear compared with traditional chain-only systems. However, the final chain drive still requires regular cleaning, lubrication, and tension adjustments after wet rides.
- Acoustic Benefits: The belt-driven primary stage operates significantly quieter than traditional chain-only systems, reducing mechanical noise during operation. (Note: A belt system may experience more limitations under extreme shock loads (such as heavy jumps with pinned throttle) compared with a heavy-duty chain, though stock belt drives are rated for extended use on the 15.8 kW SS 3.0 platform.)
Altis Sigma Heavy-Duty Chain Drive
The Altis Sigma standard edition uses a traditional 428H chain drive, while the 2026 Trail configuration comes equipped with a heavy-duty 520H chain to handle extreme shock loads. While a chain drive requires regular maintenance and produces a noticeable mechanical whine at speed, it is a deliberate engineering choice to match the bike’s raw output:
- Handling Extreme Torque: A heavy steel chain is engineered to handle the high torque output of the Sigma’s peak motor, though proper chain tension and maintenance are critical for durability under extreme conditions.
- Gearing Modifications: If you want to increase low-end climbing torque or boost top speed, changing your gear ratio is as simple as swapping out a rear metal sprocket, which is cheap and widely available.
Weight, Ergonomics, and Cockpit Comfort
The physical size and overall electric motorcycle weight directly affect rider fatigue and steering dynamics during long trail rides.

Weight and Maneuverability: The Weight Penalty
At 167 lbs, the E Ride Pro SS 3.0 is 18 to 31 lbs lighter than the 185–198 lbs Altis Sigma (depending on configuration, with 2026 high-power models weighing up to 198 lbs). This weight difference is immediately noticeable on the trail:
- The Agility Advantage (SS 3.0): The SS 3.0 feels closer to a lightweight mountain bike than a traditional dirt bike. The SS 3.0 is incredibly easy to whip through tight singletracks, hop over fallen logs, and recover from slow-speed tipping. Loading the bike into the back of a truck or putting it on a maintenance stand is significantly easier.
- The Stability Advantage (Sigma): The 185–198 lbs Sigma behaves like a genuine, lightweight dirt bike. While it requires more physical effort to steer through tight forest singletracks or heavy mud, its extra weight serves as a natural stabilizer at speeds over 50 mph. It remains planted and straight on rough roads where lighter e-motos tend to bounce.
The Ergonomic Gap: Why Tall Riders Prefer the Sigma
Many lightweight electric dirt bikes – including popular options like the E Ride Pro SS 3.0 featured in our guide to the top 10 best electric motorcycles for tall riders – are built on a compact, scaled-down frame that can feel small for taller adults. The Altis Sigma is designed with true, full-sized adult proportions, featuring a 51-inch wheelbase and a 35-inch seat height on the 2026 Trail configuration.
- Grip and Control: The Sigma features wide, motocross-style side panels. When standing on the footpegs, a tall rider can grip the chassis with their knees. This provides superior body control during jumps and corners, whereas the narrow, compact ergonomics of the SS 3.0 offer very little surface area to grip.
- Open Riding Triangle: Taller riders (especially those 6’0″ to 6’3″+) will find the handlebar-to-footpeg distance on the Sigma far more comfortable. Their knees are bent at a comfortable, natural angle on the Sigma, which prevents joint fatigue.
Suspension Performance and Linkage Progressivity
Suspension is the bridge that determines whether a bike’s power can translate into effective traction on rough dirt.

FastAce Coil vs. Progressive Linkage Air
The E Ride Pro SS 3.0 is equipped with a FastAce front fork and a FastAce rear coil shock with adjustable settings. This coil-spring setup is highly responsive and performs well on technical trails. However, the SS 3.0 uses a direct-mount rear shock without a linkage system, making its compression curve linear. Heavier or more aggressive riders may experience a harsh bottom-out on hard impacts.
The Altis Sigma features an adjustable front air suspension and a progressive rear linkage air shock. The progressive design allows the suspension to remain soft and plush over small trail chatter (rocks, tree roots) while progressively becoming firmer near the end of the stroke. However, early reviewers noted that the 2025 model’s suspension was tuned soft, with some riders experiencing bottoming out on heavy landings. The 2026 model may feature updated tuning, though official specifications remain unchanged.
Handling on Different Terrain
- Technical Trails & Woods (SS 3.0 Wins): The SS 3.0’s 167 lbs weight and short 49.6-inch wheelbase make it highly agile. It changes direction with minimal rider input, allowing you to flick the bike around tight trees with ease.
- Motocross Tracks & Jumping (Sigma Wins): The progressive linkage air suspension and longer 51-inch wheelbase are designed to better handle motocross-style riding and larger impacts. It stays composed over rolling whoops where the lighter SS 3.0 can feel jittery. (Note: Due to the soft stock suspension tune noted by reviewers, riders planning on heavy motocross use may need to adjust air pressure or seek stiffer aftermarket tuning.)
Battery Capacity, Charging, and Range
To understand how far these high-voltage machines can travel on a single charge, evaluating the true electric motorcycle battery capacity is essential, rather than relying on optimistic marketing claims.
Calculating True Energy Capacity (Watt-hours)
Watt-hours (Wh) is the only true measure of total electrical energy storage, calculated by multiplying system voltage (V) by capacity (Ah):
Watt-hours (Wh) = Voltage (V) × Amp-hours (Ah)
- E Ride Pro SS 3.0: 72V × 50Ah = 3,600 Wh of total energy.
- Altis Sigma: 97.2V × 35Ah = 3,402 Wh of total energy (utilizing Samsung 50S cells built by Greenway).
Despite the Altis running a highly efficient 97.2V system, the E-Ride carries 198 Wh of extra raw energy capacity on board.
Real-World Range Scenarios
Because the SS 3.0 carries slightly more battery capacity and weighs less, it is the better choice for riders maximizing their electric motorcycle range. Actual distance varies significantly depending on rider weight, terrain, speed, temperature, and riding mode.
- Casual Trail Riding: When cruising trails at a moderate 25–30 mph, the E-Ride SS 3.0 pulls ahead. Under very conservative riding conditions (around 15 mph), the SS 3.0 can achieve ranges of 100+ miles (officially rated at 116+ miles @ 15 mph), while typical mixed riding (25 mph) yields 64+ miles. Under favorable riding conditions, the Altis Sigma typically delivers 40-50+ miles of range, with aggressive riding (Race mode) reducing this significantly.
- Aggressive / Race Mode Riding: If you ride the Altis Sigma hard in Race mode, its high power draw will exhaust its battery quickly. Under aggressive race-style riding with constant high throttle, range can drop dramatically compared with casual trail riding, with some riders reporting significantly reduced ride times under extreme conditions. Running the E-Ride Pro SS 3.0 under similar aggressive trail conditions yields a range of 45 to 50 miles.
Charging Speed and Convenience
- Altis Sigma: Using its standard electric motorcycle charger, the Altis Sigma replenishes its 3,402 Wh pack from 20% to 80% in 2 hours, with a full 0-100% charge cycle taking approximately 3 hours (officially rated at 180 minutes for 20%-100%).
- E Ride Pro SS 3.0: The E Ride Pro SS 3.0 takes approximately 3.5 hours for a 20%-90% charge cycle, with a full 0-100% charge requiring slightly longer.
Build Quality, Reliability, and Long-Term Ownership
Understanding these ownership dynamics helps clarify which bike delivers better long-term value for different types of riders.
Real Owner Feedback and Common Issues
Neither electric dirt bike is completely free from potential issues. Based on publicly available owner discussions, enthusiast communities, and long-term user feedback, both platforms have received positive comments as well as occasional criticism.
E Ride Pro SS 3.0 Common Feedback:
Most SS 3.0 owners praise the bike’s lightweight handling, strong performance, and low-maintenance belt drive system. However, some riders have reported minor ownership issues, including brake adjustments after delivery, throttle response tuning preferences, or setup inconsistencies that may require dealer assistance. These reports appear to be isolated rather than widespread, but they highlight the importance of purchasing through a reliable dealer with proper after-sales support.
Altis Sigma Common Feedback:
The Altis Sigma’s high-voltage powertrain and premium hardware have attracted attention from performance-focused riders. Owner discussions generally highlight its strong acceleration, stable chassis, and motorcycle-style ergonomics. However, some owners have reported isolated issues including front axle bolt failures under excessive torque, display cable routing problems, and suspension tuning concerns (particularly on the 2025 model). Additionally, as a newer platform, some riders have raised questions regarding long-term parts availability and service accessibility compared with more established electric dirt bike brands.
The Sigma’s keyless RFID system is another feature frequently discussed by owners. Since the bike relies on an electronic key fob rather than a traditional ignition key, riders need to keep the fob secure during aggressive off-road riding. Additionally, because the Sigma uses advanced electronics and a high-resolution display system, certain repairs may require specialized parts or factory support.
Aftermarket Ecosystem and Upgrade Potential
For many electric dirt bike riders, customization is an important part of ownership. Both platforms offer different advantages depending on whether riders prefer modification flexibility or factory performance.
E Ride Pro SS 3.0: Stronger Aftermarket Ecosystem
The E Ride Pro SS 3.0 benefits from a broader aftermarket ecosystem. Owners have access to a wide range of aftermarket options, including:
- Handlebars and cockpit upgrades
- Brake components
- Suspension improvements
- Footpeg and protection upgrades
- Battery and controller upgrades
For riders who enjoy gradually modifying and personalizing their bike, the SS 3.0 provides more flexibility.
Altis Sigma: Factory-Built Performance Platform
The Altis Sigma takes a different approach by delivering a high-performance package directly from the factory. With a 97.2V electrical system, Samsung 50S battery cells, high-output motor technology, and progressive suspension design, the Sigma already includes many upgrades that riders typically add to other platforms.
However, because the Sigma uses a more unique frame design and high-voltage architecture, third-party aftermarket options are currently more limited compared with the E Ride Pro ecosystem.
For riders who want maximum factory performance without extensive modification, the Sigma’s out-of-the-box specification is its biggest advantage.
Price and Value: Is the Altis Sigma Worth the Extra Money?
At first glance, the pricing seems incredibly close, with the E-Ride Pro SS 3.0 listed at $4,999 and the Altis Sigma typically listed at $5,299–$5,899 (MSRP at $4,799 but actual market prices vary due to regional dealer fees and setup).
The E-Ride SS 3.0 provides excellent value through its low-maintenance belt drive system. Chain systems require constant chain lubricant, specialized cleaning solvents, and eventual sprocket replacements under high-torque abuse. By choosing the SS 3.0, you eliminate these ongoing drivetrain maintenance costs and save prep time in the garage before every weekend ride.
However, if you plan on upgrading an E-Ride SS 3.0 to hit 70 mph and have a true dirt-bike geometry, you will easily spend thousands of dollars on a custom frame extension, a progressive linkage kit, a high-voltage battery, and a new controller. In that scenario, the Altis Sigma represents incredible factory-direct value, saving you the time and expense of building a hyper-ebike from scratch.
