How does it compare?
The Flux Primo finds itself squaring off against a new generation of electrified dirt warriors. Its primary rivals include the CAKE Kalk OR, Sur-Ron Storm Bee, Zero FX, and Stark VARG. All bring a unique flavor to the mix, but few deliver the same torque-rich, modular battery approach of the Primo.
Range Comparison
The Flux Primo offers a 40 km (25 mile) range, making it more of a session-based machine unless paired with extra battery packs. The CAKE Kalk OR stretches up to 80 km (50 mi), while the Sur-Ron Storm Bee posts about 100 km (62 mi) per charge. The Zero FX edges ahead with 144 km (89 mi) in city riding, and the Stark VARG promises a solid 110 km (68 mi). Primo’s edge lies in quick-swap batteries that offset the shorter range during back-to-back rides.
Acceleration and Power
Flux Primo comes out swinging with 85 hp (63 kW) and a staggering 750 Nm (553 lb-ft) torque. The Stark VARG claims 80 hp and similar torque, putting it neck and neck. Zero FX delivers a modest 46 hp (34 kW) and 106 Nm (78 lb-ft), while Sur-Ron Storm Bee clocks in at 22.5 kW (30 hp) and 520 Nm (384 lb-ft). CAKE Kalk OR trails with 13 hp (10 kW). In sheer force, Primo takes pole position for torque-hungry riders.
Charging and Battery System
Unlike its competitors, Flux Primo’s 400V battery can be swapped in minutes, eliminating the wait typical of EVs. CAKE and Sur-Ron need about 2.5–3.5 hours for full charge, while Zero FX uses a modular pack but takes 9.7 hours standard. The Stark VARG charges in roughly 1–2 hours with a fast charger. Still, the Primo’s swap-and-go system sets it apart when time is money—or adrenaline.
Price Point Comparison
The Flux Primo comes in at $12,650 (UK £9,867 / EU €11,764). CAKE Kalk OR lands higher at $14,370 (UK £11,200 / EU €13,350), while Sur-Ron Storm Bee sells at $9,499 (UK £7,400 / EU €8,820). Zero FX asks $12,995 (UK £10,130 / EU €12,080), and Stark VARG enters the arena at around $13,000 (UK £10,140 / EU €12,090). Primo sits comfortably in the mid-tier, offering top-shelf torque and swappable batteries at a competitive price.
Overall Verdict
If you’re chasing torque, customizability, and a fast battery turnaround, the Flux Primo makes a compelling case. While its range trails rivals like the Zero FX and Stark VARG, its quick-swap tech, futuristic clutch, and tech stack make it a standout for riders who want to ride hard and recharge later—literally.
