Ultra Bee

Full-size feel. Serious power. Ultra control.

The Ultra Bee steps into a bigger chassis with the punch to match. With 21kW peak power (Turbo) and a new 74V 60Ah battery pack, it is built for fast trail, technical climbs, and real off-road abuse.

Features like the crawling control function, upgraded chassis rigidity, and the advanced MTPA/MTPV controller make it feel planted and predictable when the terrain gets sketchy.
