Altis Sigma
✓ In stock · Ships United States, Europe & Worldwide
Altis builds one electric dirt bike, the Sigma, and puts everything into it rather than splitting attention across a range — the payoff is a 98V high-voltage system delivering roughly 22kW peak output, genuinely strong numbers for a bike priced at $4,500, just under our $5,200 category median. That power figure puts the Sigma ahead of several similarly-priced machines on paper, including the RFN Warrior Pro at $4,200 and the 79Bike Falcon Pro at $4,800, both of which lean more on value positioning than documented output. It's a good fit for riders who've outgrown entry-level electric dirt bikes and want proven trail-and-track performance — instant torque, near-silent running — without paying flagship prices like the $11,000-plus KTM Freeride line. As an off-highway vehicle, the Sigma is built for private land and trail riding, not the street; making it street-legal would depend on your local registration, insurance and licensing rules, so ride with a helmet and proper gear and check your state's OHV laws first. The Sigma ships worldwide, including Europe. Exact specifications and configurations vary — confirm current details with our team before ordering.

The Sigma is the more budget-friendly Sur-Ron alternative here; the Ultra Bee brings a deeper aftermarket. Our team can help you weigh the two against your riding style.
