601 newton-metres.
The 2026 hairpin winding turns at 8,300 rpm instead of 7,800 and makes 601 Nm — 443 lb-ft — through a 450 phase-amp controller. That is the number that matters on a steep, loose climb, because torque is what gets you up it and rpm is what keeps you there. It comes with 20 mm more front suspension travel, over an inch more ground clearance at 13 inches, and a stronger 520H chain in the rear linkage to handle it.

Down to the last bolt.
A 25 kW hairpin, turning to 8,300 rpm.
Hairpin windings pack more copper into the same stator, which is why this makes 601 Nm rather than the 500-odd a conventional winding manages at the same size. The 2026 version spins to 8,300 rpm, up from 7,800, so the torque stays with you further up the range instead of tailing off exactly when a climb gets steep.
97.2 volts, and three hours to full.
A 97.2V 35Ah pack on Samsung 50S cells — 3,402 watt-hours. High voltage is what lets the controller push serious current without the losses that cook a lower-voltage system, and it is why this charges in three hours rather than most of a day. Fifty miles of real riding, or a hundred if the day is kind.
Adjustable air springs, triple-tree forks.
Air-spring suspension front and rear, adjustable for your weight and the ground you ride, on triple-tree forks that keep the front end where you put it at speed. The 2026 version adds 20 mm of front travel and lifts ground clearance to 13 inches, which is the difference between clearing a rut and finding it with the frame.
Four pistons, and five regen modes.
Four-piston discs at both ends, with five selectable regenerative braking modes behind them. Set regen high and the bike slows the moment you close the throttle, putting charge back into the pack on every descent; set it low when you want to carry speed and brake on your own terms. It changes how the bike rides more than any other setting on it.
A 3.5-inch TFT, unlocked by NFC.
Full-colour TFT with speed, battery, ride mode and regen level, and an NFC key instead of a barrel lock — tap and it wakes. It is a small thing until you are wearing gloves in the cold and there is no key to find.
Everything under your thumbs.
Ride mode, regen level, lights and the high beam on the bars, with a twist throttle on the right. Nothing that matters while you are moving is buried in a menu, which is the only sensible way to lay out a bike that makes this much torque.
A 35-inch seat, a 51-inch wheelbase.
Taller for 2026 — 35 inches at the seat, up from 33 — over a 51-inch wheelbase. That is real dirt-bike geometry rather than the compact stance of a pit bike, so it stays settled at speed and gives a full-size adult somewhere to stand up. The Baja-style headlight is new too, and it throws far enough to ride after dark.

The numbers.
2026 Altis Sigma, Standard and MX.
*Our published top speed is the governed, road-appropriate figure. This is an off-road machine and it is capable of a great deal more unrestricted — ride it on private land, trails or a closed course where you have permission, and wear proper protective gear. It is not street legal in most jurisdictions; check your local rules before you buy.
Performance figures were adjusted downwards in 2026: we calculate them for a rider of 200 lbs rather than repeating the manufacturer's best case. The maximum load was adjusted the same way — it does not mean the bike cannot carry you, only that stated performance may vary. Every Altis Sigma Standard we ship is the updated 2026 unit.
What riders say.
Before you buy.
Wheel sizes. The Standard runs 19 inches front and rear; the MX runs a 19 in front and a 16 in rear. The MX's smaller rear wheel drops the gearing and lowers the back of the bike a little, which suits tighter, more technical riding and shorter riders. The Standard is the more neutral, faster-feeling setup.
The hairpin powertrain went up to 25 kW and 8,300 rpm, torque went to 601 Nm, front suspension gained 20 mm of travel, ground clearance went over an inch to 13 in, the seat went from 33 to 35 in, there is a new Baja-style headlight, and the rear suspension linkage now runs a stronger 520H chain. Every Standard we ship is the 2026 unit.
Treat it as an off-road machine. In most places a bike like this will not meet the requirements to be registered for road use, and some cities restrict them outright. It belongs on private land, trails and designated riding areas — check your local rules before you buy.
There are five levels. High regen slows the bike hard the moment you close the throttle and puts charge back into the pack, which is genuinely useful on a long descent. Low regen lets it coast so you can carry speed and brake on your own terms. Most riders end up switching between them depending on the trail.
Higher voltage lets the controller move the same power at lower current, which means less heat and less loss in the wiring. It is why a 3,402 Wh pack charges in three hours and why the bike holds its output rather than fading when you lean on it.
198 lbs. That is real dirt-bike weight rather than pit-bike weight, so plan on a ramp and ideally a second pair of hands to load it. It ships by palletised freight for the same reason.
The seat is 35 in and the wheelbase 51 in, which suits full-size adults. If you are shorter, the MX sits a little lower at the back. You can also view the bike at full size in your own garage from your phone before you commit.
