The Honeywhale B20 is known as the cheapest electric bicycle on the internet and, according to the video, it is the second best-selling on Mercado Livre, with more than a thousand units sold. In this video, which launches the Bike of the Week series, Luan Amancio looks for the catch: how far it goes, whether it climbs hills, how much weight it carries and what the right price is.
Why it is so cheap
The B20 is from Honeywhale, a Chinese brand with an official store on Mercado Livre, meaning the brand itself sells it. The price makes sense just by looking at it: it is a small bike with 14-inch wheels, a low frame and a handlebar that folds down. With the handlebar folded it is 40 cm wide, fits in a car trunk and an elevator and tucks into the corner of the living room. It weighs only 21 kg. Luan notes that Honeywhale paid nothing for the video and that the official listing link is in the description and in the pinned first comment.
Motor and gears
The motor is 350 W and reaches 440 W at peak, less than half the power of the big 1,000 W electric bikes. There are three gears from the factory: up to 15, up to 20 and up to 25 km/h. The maker itself unlocks a fourth, and it is written in the listing: with the bike off, hold the power button for 10 seconds until F2 appears on the screen. The fourth gear takes the B20 up to 32 km/h, which, according to the video, is the legal limit for riding without a plate or a driver's license.
How far it really goes
The listing says 35 km per charge. In real life, a 95 kg buyer, always in the fastest gear, gets 27 to 30 km. That is why Luan asks you to be realistic: count on about 20 to 25 km if you use only the throttle, and if you need more, you will probably have to pedal along. To charge it, a regular outlet is enough: it takes 4 to 6 hours and costs less than 30 centavos of electricity.
Does it climb hills?
The listing says it climbs slopes of up to 15 degrees, and this is where the smaller motor shows. On flat streets it flies, and on a gentle climb it goes on its own. On a steep hill, almost every owner says the same thing: put it in gear 3 and help with the pedals. Anyone who lives at the top of a hill and doesn't want to pedal at all needs a much stronger motor.
Weight, brakes and suspension
The B20 carries 120 kg, and a 108 kg buyer wrote that it takes him with no trouble. It is well equipped on brakes: it has disc brakes on the front and rear wheels, and owners praise them as strong. What it doesn't have is suspension: on a street with potholes you will feel it, so take it easy.
The price changes all the time
Even as the cheapest, the price doesn't stand still: Luan tracked the B20 for 27 days and the price changed 12 times. Today it goes for around R$ 2,000, in 12 interest-free installments. Over the past month it reached almost R$ 2,400, and the lowest price he saw was R$ 1,903. If the price is close to R$ 1,900 when you click the link, it is time to buy. To be alerted when the price really drops, he points to his WhatsApp deals group, which is free.
The math against the bus
In a city like São Paulo, a round-trip bus ride every workday costs more than R$ 230 a month. In under 10 months the B20 pays for itself, and after that your transport costs just the electricity from the outlet. Always buy through the official link; if it arrives and isn't what you expected, you have 30 days to return it, with free return shipping.
Conclusion
The B20 makes sense for short, flat trips, 20 to 25 km on the throttle alone, with a rider of up to 120 kg, and it is very cheap next to 1,000 W bikes. Anyone who lives on a steep hill or wants to ride without pedaling at all needs a stronger motor. Check the price on the official listing: if it is close to R$ 1,900, it is a good day to buy.
