Altis Sigma Top Speed Unleashed: How Fast Does the 22Kw Electric Dirt Bike Really Go?
By Alexander Ross
What is the verified GPS top speed of the Altis Sigma?
Under real-world conditions on level ground with an average-weight adult rider, the stock Altis Sigma reaches a verified top speed of 72 to 74 mph (116 to 119 km/h).
Can the Altis Sigma sustain its top speed until the battery runs out?
No. Running continuously at full throttle in Hyper Mode triggers the thermal management system after 90 to 120 seconds. The controller tapers output to protect internal components, settling sustained velocity closer to 58, 60 mph until temperatures drop.
How does sprocket gearing affect the bike’s top speed?
The factory setup balances high-speed cruising with low-end climbing. Installing a larger rear sprocket increases low-end climbing torque while reducing top speed to roughly 60, 64 mph. A smaller rear sprocket can push asphalt top speeds toward 78 mph, though it increases stress on the controller during low-speed hill starts.
Is the Altis Sigma street legal straight from the crate?
No. The Altis Sigma ships as a dedicated off-highway electric motorcycle. Converting it for street legality requires adding mirrors, turn signals, high/low beams, highway-rated DOT tires, and registering it through local Department of Motor Vehicles procedures.
