Surron Ultra Bee

SurRon Ultra Bee 2025 – Now Faster!
The next evolution in electric off-road performance is here. The 2025 Ultra Bee pushes boundaries with a massive power upgrade, redesigned suspension, and high-efficiency motor tech—all while retaining the nimble ride feel SurRon is known for.

Power Upgrade – Now 21kW Peak
Tap into insane acceleration with the all-new Turbo Mode, peaking at 21kW and maintaining 18kW continuous in Sport Mode. That means 0–31mph in just 2 seconds, or a blistering 1.1 seconds to 18.7mph off the line.  The 2024 outgoing model peaked at just 12.5kw.  While that was plenty, this is a huge and fully welcomed upgrade!
