Range has moved to the center of Vietnam's electric two-wheeler market. The old fear of a dead battery mid-trip, which kept many riders on petrol, is being answered by models claiming 150-200 km per charge in standard form, and over 260 km in one special configuration. For someone covering 20-30 km a day, a 150-200 km figure means roughly 5-7 days between charges on paper, though load, speed, temperature, terrain, tire pressure and riding habits all whittle down the real-world number.

Dat Bike has turned long range into a brand-wide pitch: across all generations, seven of its models are rated at 200 km or more per charge, five of them currently on sale in the Quantum S and ERA lines. The flagship Quantum S1 claims up to 285 km from a 6.4 kWh battery and starts at 49.9 million VND with battery, charger and VAT included; it runs a 7,000 W motor, tops out at 100 km/h, and adds hill assist, cruise control and IP67-rated water resistance. The commuter-focused ERA E1 and E2 manage 200 km from a 4.3 kWh pack at 33.9 and 29.9 million VND respectively, and plug straight into a household 220V socket — 15 minutes on the 2,700 W Boost setting adds about 30 km.

Chinese two-wheeler maker Yadea's Velax U is rated at up to 173 km on the WMTC cycle from twin 74V-27Ah batteries totalling about 4 kWh, with a 94 km/h top speed and a connected stack covering GPS tracking, remote unlocking, electronic geofencing and over-the-air updates. VinFast's Evo Grand is the outlier, since its range hinges on the chosen battery option — the standard setup carries a 2.4 kWh LFP pack.

Pega's eSmart AI rounds out the group with 110 km and 160 km versions, the latter launched at 55 million VND. Its distinguishing move is swapping lead-acid for a removable 3.1 kWh lithium-ion pack — a boon for apartment dwellers with no socket at their parking spot — alongside voice control and a 6.5-inch display.
