Altis Sigma Electric Dirt Bike
Off-road performance is never about a single headline number. It comes from a motor, battery, controller, frame, suspension, brakes, and tires working together. When riders compare an Altis electric dirt bike, understanding those parts makes the spec sheet far easier to read. At Wyrd Ryds, we carry the Sigma, so this listicle walks through eight components using the details on its product page, and it flags the places where you should confirm specifics with us. An FAQ follows at the end.
1. The 25kW Hairpin Motor
The listing describes a 25kW peak hairpin motor, shown as 27 to 34 horsepower, and the manufacturer's quote cites 34 HP at peak. Hairpin windings pack copper tightly, which is generally associated with efficient power delivery. This is the core of the bike's acceleration and its ability to pull up steep, loose climbs.
2. The Samsung-Cell Battery Pack
Power is only useful if the battery can supply it. The listing names the ALTIS PowerPack, a lithium-ion pack rated at 35Ah, and the description says it uses Samsung cells. Charging is listed as 80% in 2 hours and 100% in 3 hours. The listed range is 50 miles, measured with a 160 lb rider at a constant 18 mph, so expect less if you ride hard, climb often, or weigh more.
3. The 450A Controller
If the motor is the muscle, the controller is the brain. The listing shows a 450A controller, which governs how much current flows to the motor and therefore how hard the bike can accelerate.
4. The Forged Aluminum Alloy Frame
The frame is listed as forged aluminum alloy. Aluminum keeps weight down while adding stiffness. The bike's listed net weight is 198 lbs, with a maximum load of 300 lbs, which gives you a sense of how it is built to be ridden.
5. Adjustable Air Spring Suspension
Suspension is one of the biggest factors in off-road control. The listing shows adjustable air spring suspension, which lets you tune the setup to your weight and terrain rather than accepting one fixed feel.
6. Hydraulic Brakes And Adjustable Regeneration
Stopping a bike with this much power requires serious brakes. The listing shows heavy-duty four-piston hydraulic brakes. It also notes adjustable regenerative braking, which provides different deceleration settings when you roll off the throttle.
7. Off-Road Tires On The Wheel Setup
Tires are the only contact with the ground. The listing names CST tires and mentions an off-road wheel setup. Tire choice affects grip in loose dirt, mud, and sand, and it is one of the easiest components to tune over time. Because the page says configurations vary by model year, confirm the supplied wheel and tire setup before ordering.
8. The TFT Display And Lighting
The 3.5 inch TFT display includes NFC access, and the lighting package lists a headlight, tail light, brake light, and turn signals. These are rider-technology details rather than performance parts, but a clear display and proper lighting make a powerful bike easier to manage and to use responsibly.
Why The Combination Matters
Compared with many other Electric Bikes, an Altis electric dirt bike like this one is defined by how its parts are matched. A big motor with a weak brake, or a strong frame with a poor suspension, would be a poor package. Looking at the components together, as the listing does, gives a clearer picture than any single figure.
Things To Confirm Before You Buy
The listing is candid about a few points, and they are worth taking seriously:
Model year differences: ALTIS publishes separate configurations, so confirm the supplied year and wheel setup. Year-specific headlight, axle, and suspension upgrades are not described as standard across every Sigma.
Speed and use: The bike is sold for off-road or track use only and is described as speed and power limited. The listing asks buyers not to bypass this restriction.
Ordering terms: A 5% cancellation fee applies, returns are not accepted once an item has shipped, and discount codes cannot be used.
Eligibility: You must be 18 or older, and ID verification is required.
Price And Availability
The listed price is $5,899. Stock changes quickly, so check the listing for current availability and delivery options.
Final Thoughts
The Sigma's off-road capability comes from eight components working together: a hairpin motor, a Samsung-cell battery, a 450A controller, a forged aluminum frame, air suspension, hydraulic brakes, off-road tires, and rider technology. If you are considering an Altis electric dirt bike, read the spec sheet this way, and confirm the model year before you order. Wyrd Ryds is happy to answer questions and help you choose.
