- Has a three-speed selector (up to 30 km/h advertised), reverse gear, a parking lock and an alarm on the remote.
- Advertised range: 25 to 30 km on the lead-acid battery and 40 to 45 km on the lithium one, about 15 km more per charge.
- The motor is on the front wheel and the rider's weight sits behind it: on a steep hill the wheel can slip.
- Price in the video's research: lead-acid from R$ 4,140 and lithium from R$ 5,999, a difference of about R$ 1,860.
The electric tricycle is an alternative for people who already have trouble walking, or who are looking for a solution for a father, mother, grandmother or grandfather. In this video, Luan shows the Duos Fox and compares the two battery versions using the data he found in the listings.
How it works
You sit, rest your feet and twist the grip; when you let go, it stops accelerating, and the brake works normally. Reverse helps get out of tight spots and garages. According to the listings, the motor cuts acceleration when you squeeze the brake, and the levers have a parking lock. There's a basket at the front and space behind for shopping at the market.
First question: does the route have hills?
The motor is on the front wheel and a good part of the weight sits behind it. One seller states that the tricycle isn't recommended for hills or garage ramps, and a buyer reports slipping on a climb. It's worth looking at the entire route, including the garage entrance. On flat routes it works well; with a steep hill in the routine, Luan would look for another option.
Second question: who looks after the battery?
The listings advise charging the battery at least every 15 days, even if the tricycle is parked. If it's for a relative who doesn't usually remember that, agree beforehand on who will keep track of the charging.
The math of trips
For a pharmacy 2 km from home, the round trip adds up to 4 km. With the advertised numbers, the lead-acid battery would give close to six trips like that and the lithium one close to ten. It's a calculation to help you visualize it, with no guarantee, and it's good to leave a margin to get back home. The estimates apply to users up to 90 kg.
Price and which to choose
In a comparison, the same model appeared in one store for R$ 6,600 and, on Mercado Livre, another lead-acid version was close to R$ 4,140, a difference of more than R$ 2,000. Luan suggests comparing battery, shipping, assembly and what's included, because the lowest price on the page isn't always the lowest final value. For short, flat trips and a tight budget, he would consider lead-acid. If the person needs more range, lithium.
Conclusion
The Duos Fox can give back independence to people who need a ride for their daily routine, as long as the route is flat and someone looks after the battery.
