How does it compare?
Speed
The Kawasaki Ninja e-1 manages a top speed of approximately 100 mph (160 km/h). This places it well within the spirited performance sphere, but a bit behind the beastly Harley-Davidson LiveWire One, which roars up to 110 mph (177 km/h). The Zero SR/F blitzes through with a top rate of 124 mph (200 km/h), leaving others huffing fumes. Not far behind, the Energica Eva Ribelle peaks at 125 mph (201 km/h), making it a serious contender. Meanwhile, the more urban-oriented BMW CE 04 caps at a modest 75 mph (120 km/h), making it the stately commuter amidst these thrill-seekers.
Range
Range anxiety? Not with the likes of these machines. The Kawasaki Ninja e-1 offers a solid 100 miles (160 km) range on a single charge, which aligns it closely with the Harley-Davidson LiveWire One and its 105 miles (169 km) range. However, the Zero SR/F seizes the day with an eye-popping 161 miles (259 km) in city conditions. The Energica Eva Ribelle promises a hearty 143 miles (230 km), hovering above the Kawasaki. The BMW CE 04, crafted more for urban escapades, delivers 80 miles (129 km).
Power
The heart of these beauties, the powerplant. Kawasaki Ninja e-1 kicks out a respectable 20 kW (27 hp), enough to zip through city streets with gusto. On the other hand, the Harley-Davidson LiveWire One flexes an impressive 78 kW (105 hp). Yet, the supreme fire-breather here is the Zero SR/F with a titanic 82 kW (110 hp). Not to be outdone, the Energica Eva Ribelle belts out 107 kW (145 hp), edging out the Zero. The BMW CE 04 rounds off the pack with a commendable 31 kW (42 hp).
Charging Time
In the age of instant gratification, charging time is crucial. The Kawasaki Ninja e-1 recharges to 100% in about 4 hours, par for the course. The Harley-Davidson LiveWire One accelerates this process with a 1-hour rapid DC charge. Meanwhile, the Zero SR/F boasts a nimble 1.5-hour rapid charge option. The Energica Eva Ribelle impresses with just over an hour to full charge using a Level 3 charger. The BMW CE 04 comfortably pops back to life in around 4 hours using standard charging methods.
Price
Wallets at the ready. The Kawasaki Ninja e-1 is arguably the most pocket-friendly, retailing at approximately $7599, £5599, or €6499. Steeper on the spectrum, the Harley-Davidson LiveWire One commands a princely $21,999, £19,795, or €22,990. Equally elite, the Zero SR/F holds its own at $20,495, £17,990, or €19,990. The Energica Eva Ribelle ascends further, priced at $23,000, £20,480, or €24,890. Finally, the more commuter-centric BMW CE 04 enters at $11,795, £11,700, or €12,960.
