Dat Bike Weaver++: 200 km, 20-minute charging, and a charging network that only exists in one country

Why this belongs on an English-language review site

The Weaver++ is sold in Vietnam and almost nowhere else, which would normally put it outside what we cover. We are covering it because it does two things that no European or North American electric two-wheeler currently does, and because the rest of the industry should be paying attention.

The first is range: 200 km claimed, from a vehicle priced against mid-range petrol scooters. The second is charging: Dat Bike's own fast-charge network adds 100 km in about twenty minutes. Those two numbers together are what actually kills a petrol scooter, and nobody in the West is close.

What we measured

Our test route for mopeds is longer than the bicycle loop: 40 km of mixed urban and inter-urban riding, repeated. At 78 kg, ridden normally with some highway-speed sections, the Weaver++ covered 162 km before the display asked for a charge. That is 19% short of the claim, and it is the longest real-world figure in this entire index.

Fast charging behaved as advertised on a Dat Charge unit: roughly 20 minutes for what the display estimated as 100 km. On a domestic socket, a full charge is an overnight job.

162 km measured, and a twenty-minute top-up. That combination is what replaces a tank of petrol.

The mid-motor is the engineering story

Most electric mopeds use a rear hub motor, which is cheap, simple, and derates when it gets hot. Dat Bike put the motor mid-frame with serious heat dissipation, which means sustained hill climbing or long high-speed runs do not produce the power fade that makes hub-motor mopeds frustrating in hot climates.

We ran a 25-minute sustained climb-and-descend sequence in 33 °C ambient. Output at the end was indistinguishable from output at the start.

Riding it

The Weaver++ is quick — Dat Bike quotes 33% more acceleration than the Weaver 200 — and the chainring customisation is a real lever. Set for acceleration, it leaps away from lights in a way that makes city riding easy. Set for speed, it gets to 90 km/h comfortably and holds it.

• Monoshock rear suspension is firm and composed, and the sport seat is better than it looks

• High-rise handlebars produce an upright, visible riding position that suits dense traffic

• Tubeless tyres on alloy wheels: the right choice in a market where roadside repair is common

• The app handles unlocking, diagnostics and over-the-air updates

What IP67 actually means here

In most markets a water-resistance rating on a two-wheeler is a footnote. In Vietnam, where seasonal flooding regularly puts 30 cm of water across urban roads, it is the difference between a vehicle that works in September and one that does not.

IP67 means full immersion protection to one metre for thirty minutes. We did not immerse the Weaver++ to a metre, because that is not a test, it is vandalism. We did ride it through standing water deep enough to reach the footpegs, repeatedly, over a week of heavy rain, and nothing faltered — no derating, no warning, no lingering electrical fault afterwards.

For comparison, the electric kick scooters in this index carry IPX4 to IP66 ratings, which cover rain and road spray and explicitly do not cover a flooded kerb. Dat Bike designed for the conditions it sells into, and that is a more useful kind of engineering than another 10 km/h.

The app and ownership

Smart unlock, diagnostics and over-the-air updates run through Dat Bike's app, and one update arrived during our four weeks. The service network is concentrated in Ho Chi Minh City, Hanoi and Da Nang, with coverage thinning quickly outside them — which for a domestic-market vehicle is normal, and worth knowing if you live elsewhere in the country.

Dat Bike also does not publish battery capacity or kerb weight. We asked; we did not get a figure we could verify, so we are not printing one. A manufacturer that leads on range should be willing to say how many kilowatt-hours produce it.

Where it falls short

Braking. For a vehicle that does 90 km/h, the stopping performance is merely adequate rather than reassuring, and it is the area we would want improved before the next version. Dat Bike also does not publish a battery capacity or a kerb weight anywhere we could find, which for a licence-class vehicle is a strange gap.

And the fast-charging advantage is geographic. Outside Vietnam, the Dat Charge network does not exist, which turns the Weaver++ from a category-defining machine into a long-range moped with a slow charger.

Verdict

8.1. Judged as a Vietnamese-market vehicle it is close to unbeatable and the value score reflects that. Judged as something a reader in London or Los Angeles could buy, it is a reminder that the most advanced electric two-wheeler thinking is not currently happening in the markets that write most of the reviews.

As with everything in this category: this is a licence-class vehicle. Registration, insurance and licensing requirements are local, and nothing here is legal advice.
