How does it compare?
Speed
The ZERO SR/S Standard can whip you through the streets at a top speed of 124 mph (200 km/h). It’s no slouch, but the Lightning LS-218 roars ahead with a blistering 218 mph (350 km/h), making it the Usain Bolt of electric motorcycles. Meanwhile, the Harley-Davidson LiveWire tops out at 110 mph (177 km/h), the Energica Ego clocks in at 150 mph (241 km/h), and the BMW CE 04 lags with a max speed of 75 mph (120 km/h).
Range
The ZERO SR/S Standard boasts a respectable range of 161 miles (259 km) under mixed riding conditions. The Harley-Davidson LiveWire is nipping at its heels with a 146 miles (235 km) range, while the Energica Ego flexes with 120 miles (193 km). The Lightning LS-218 is not only about speed; it provides 100 miles (161 km). Last and perhaps least in range, the BMW CE 04 barely manages a 80 miles (129 km) trek on a single charge.
Power
The power dynamics of these electric beasts are splendid. The ZERO SR/S Standard packs a punch with 110 horsepower (82 kW). Notably, the Harley-Davidson LiveWire revs in with 105 horsepower (78 kW), and the Energica Ego muscles in with a staggering 145 horsepower (108 kW). But if we talk pure raw power, the Lightning LS-218 stands unparalleled with 200 horsepower (150 kW). The BMW CE 04, designed more for the urban jungle, churns out a modest 42 horsepower (31 kW).
Charging Time
Charging antics? The ZERO SR/S Standard takes about 2.5 hours to hit 95% with a Level 2 charger. The Harley-Davidson LiveWire requires 1 hour for an 80% charge on a DC Fast Charger. The Energica Ego swiftly gets to 85% within 30 minutes using fast charging. Lightning-fast by name, the Lightning LS-218 also demands a mere 2 hours for a Level 2 charge. Finally, the BMW CE 04 needs around 1.5 hours for an 80% top-up.
Price
Let’s talk wallet drainers. The ZERO SR/S Standard rolls in at $19,995 (£14,961; €16,998). The competition gets steep with the Harley-Davidson LiveWire at $29,799 (£22,333; €25,288), and if you fancy the Italian stallion, the Energica Ego stands at $34,000 (£25,341; €28,873). The speed-fiend Lightning LS-218 takes it up a notch to $38,888 (£29,000; €33,000). The commuter-comfy BMW CE 04 is kind to your bank at $11,795 (£8,848; €9,924).
