The Altis Sigma 2026 is built for riders who want electric motocross intensity without the weight, noise, or maintenance routine of a gas-powered race bike. Its 98V hairpin motor, 25 kW peak output, 601 Nm of torque, 19/19 Trail wheel setup, and claimed 80+ mph top speed place it firmly in high-performance electric motorcycle territory.
This is not a casual commuter e-bike. The Sigma is an aggressive off-road machine for experienced riders, private-property owners, closed-course racers, and trail enthusiasts who want instant response from a compact 90 kg platform. The aluminum alloy forging frame, 13-inch ground clearance, 220 mm front travel, and 200 mm rear-wheel travel support a chassis designed to attack terrain rather than simply cross it.
If you are searching for an altis sigma electric dirt bike, comparing the altis sigma vs e-ride pro sr, or asking whether the altis sigma 80 mph claim is real, the answer depends on configuration and conditions. The official 2026 specification lists an 80+ mph reference with the Trail’s 19/19 wheels and 39T sprocket, but actual speed depends on rider weight, battery charge, gearing, terrain, temperature, and setup.

98V Electric Dirt Bike Power and Samsung Battery Architecture
The 98v electric dirt bike platform uses a 25 kW peak hairpin motor paired with a 97.2V/35Ah Samsung 50S battery pack in the 2026 Performance Pack reference. The official Altis page rounds the system to 98V and lists 3.402 kWh of energy content, giving the Sigma a high-voltage character with sharp throttle response and strong sustained acceleration.
The listed maximum torque is 601 Nm, or approximately 443 ft-lb, with the 39T sprocket. That figure helps explain why the Sigma feels more like an electric motorcycle than a conventional e-bike. Power arrives immediately, so riders should learn the controls and choose the correct riding environment before exploring the upper performance range.
The official charge reference is approximately 120 minutes from 20% to 80% and 180 minutes from 20% to 100% using the listed AC 110V/112V 12.5A input. Charging times can change with battery temperature, state of charge, charger output, and power supply conditions.
Altis Sigma 80 MPH Performance and Trail Control
The altis sigma 80 mph claim is listed for the 2026 Trail setup with 19-inch front and 19-inch rear wheels and a 39T sprocket. The larger, balanced wheel configuration is designed to carry momentum across rough terrain while maintaining predictable handling at speed.
Real-world top speed is never a guarantee. Wind, tire pressure, rider position, battery voltage, gearing, terrain, temperature, and controller settings all affect the result. Riders should treat 80+ mph as an ideal-condition performance reference and use protective equipment, proper riding technique, and a controlled private or closed-course environment.
The Sigma is air-cooled, which keeps the system straightforward and avoids the added complexity of liquid cooling. That simplicity benefits owners who value serviceability, but sustained high-load riding still requires attention to battery temperature, charging procedure, belt or chain condition, brakes, tires, and suspension settings.
Altis Sigma Trail vs MX: Choosing the Right Wheel Package
The Altis Sigma Trail vs MX decision comes down to terrain, handling preference, and riding style. The Trail specification uses a 19-inch front and 19-inch rear wheel setup with a 39T sprocket and an 80 mph top-speed reference. This configuration is well suited to riders who prioritize rollover ability, stability, and fast open-terrain control.
The displayed Sigma MX option uses a 19-inch front and 16-inch rear wheel setup. A smaller rear wheel can create a more compact, responsive feel for motocross-style riding, jumps, tight turns, and riders who prefer quicker chassis reactions. Exact MX gearing, suspension settings, and final specifications should be confirmed with the dealer.
Neither configuration is universally better. Choose Trail for open trails, rocks, ruts, and high-speed terrain. Choose MX when track-style handling, shorter rear-wheel response, and a more compact motocross stance matter more than maximum rollover stability.
E Bike Motocross Handling, Suspension, and Frame Strength
The e bike motocross buyer will appreciate the Sigma’s forged aluminum alloy frame and performance-oriented suspension numbers. The official 2026 specification lists 220 mm of front travel, 85 mm of rear suspension travel with linkage, and 200 mm of rear-wheel travel.
With a 35-inch seat height, 13-inch ground clearance, 51-inch wheelbase, and 26-degree steering head angle, the Sigma offers a serious dirt-bike riding position. The 90 kg weight with battery is light enough for quick line changes while providing a stable platform when the terrain becomes fast and rough.
Large brake hardware supports the power level. The official specification lists a 260 mm front brake disc and 220 mm rear brake disc. Brake setup, pad condition, rotor alignment, tire grip, and rider technique remain critical when carrying high speed into a corner or downhill section.
Altis Sigma vs E-Ride Pro SR: Which High-Power E-Moto Fits Better?
The altis sigma vs e-ride pro sr comparison should begin with configuration rather than brand loyalty. The Sigma’s defining traits are its 98V electrical architecture, hairpin motor, 25 kW peak output, 601 Nm torque reference, 90 kg weight, and Trail or MX wheel choices.
An E-Ride Pro SR may offer a different battery capacity, motor calibration, controller strategy, suspension package, wheel configuration, and dealer support depending on the model year. Compare verified specifications for the exact units under consideration instead of relying on broad claims from social media or used listings.
The Sigma makes sense for riders who value high voltage, aggressive peak performance, the 19/19 Trail setup, and the distinctive response of a hairpin motor. A buyer prioritizing a different battery range, suspension tune, local service network, or price should evaluate the E-Ride Pro SR on those specific criteria.
Best Buy Dirt Bikes: Is the Altis Sigma Right for You?
Shoppers searching for the best buy dirt bikes are often balancing performance, reliability, range, upgrade potential, dealer support, and total ownership cost. The Altis Sigma is a strong candidate for experienced riders who want a high-output electric racing dirt bike, but it is not the best choice for every beginner or casual trail user.
The Sigma has an estimated US price reference of approximately $4,799 on the official page, although the 2026 version is currently shown as sold out online. Final pricing can change with MX or Trail configuration, freight, setup, taxes, warranty, dealer inventory, and shipping destination.
If you are searching for altis sigma for sale, buy altis sigma, altis sigma nearby, or altis sigma near me, confirm whether the listing is for the 2025 or 2026 version. Verify the battery pack, motor revision, wheel size, sprocket, display, suspension, charger, warranty, and included accessories before making a payment.
Altis Sigma USA Shipping and Dealer Availability
For altis sigma USA shipping, buyers should confirm whether the unit ships from a US warehouse or requires special freight handling. A complete quote should identify the motorcycle price, shipping or freight charge, setup or PDI fee, taxes, insurance, delivery estimate, included charger, battery, and warranty terms.
The official Altis page currently directs sold-out online shoppers to a local dealer. RONSTER BIKES can help buyers compare available Trail and MX configurations, verify model year, review the final invoice, and confirm delivery details before purchase. Shipping availability may vary by state and inventory location.
The Sigma is designed for off-road and closed-course use unless a specific configuration is legally approved for public-road operation. It is not a standard street-legal e-bike. Verify your local rules for title, registration, insurance, equipment, public-road use, trail access, helmet requirements, and riding locations.
