The HITWAY BK-S3 Trekking carries a 720 Wh battery. That is 43% above the median for a touring e-bike, and it is the number that sets this bike apart from its class. It pairs that battery with 120 Nm of torque and a 29.5 kg build. The result is a heavy, strong touring bike with a long claimed range and a price to match.
You get a 48 V system rated at 250 W and a top speed of 25 km/h. The manufacturer claims 175 km of range, while the MathBikes estimate is 47 km. That gap matters more than any single figure on the page. This bike suits riders who want high torque and a large battery and who accept the weight and price that come with them.
What the numbers say
| Spec | This bike | Median for its type |

The table shows a bike that is bigger than its class on every measure. It carries 43% more battery, 18% more weight and 140% more torque than the median touring e-bike. Its estimated range is 42% above the median, and its price is 82% above it. You pay more and carry more, and you get more capacity and more torque in return.
Questions people ask about this model
How much does the HITWAY BK-S3 Trekking weigh?
It weighs 29.5 kg. That is 18% above the median touring e-bike at 24.9 kg, so plan for a bike that is hard to lift onto a rack or carry up steps. The maximum payload is 150 kg, which is generous for a bike of this weight.
How much torque does it have?
The motor is rated at 120 Nm. That is 140% above the median of 50 Nm for this type, so it is the strongest figure in its class by a wide margin. Rated motor power is 250 W and battery voltage is 48 V. The motor type is not published, and peak power is not published either.
What speed class is it?
The top speed is 25 km/h. The speed class is not published, so you cannot confirm from the specifications how it is classified where you ride. A throttle is not listed either. Ask the seller before you buy if either point matters to you.
How far does it really go?
The manufacturer claims 175 km. The MathBikes estimate is 47 km, with a band of 42 to 53 km, which is 73% below the claim. The estimate uses one reference ride for every bike: Tour assist, rolling terrain, mild weather, a brisk pace and a 80 kg rider. It is an estimate from a published formula, not a measurement, and nobody has ridden this bike for the site. You can run your own figures through the range calculator.
What does it cost to run?
The price is 1944 USD, which is 82% above the median of 1068 USD for this type. The battery holds 720 Wh at 48 V and 15 Ah, so charging cost depends on your local electricity price rather than on the bike. The warranty is not published, so you cannot weigh repair risk from the specifications alone. The cost calculator lets you put your own tariff and distance into the sum.
Where it falls short
The weight is the clearest cost of the large battery. At 29.5 kg the bike is 18% heavier than the median touring e-bike, and that weight shows up every time you stop, lift or store it. The price is the second cost, at 82% above the median. The range claim is the third, because the estimate sits 73% below it.
Who should buy it
Buy it if you want torque and battery capacity above everything else in the touring class and you can handle the weight. The 150 kg payload and the 25 km/h top speed suit loaded, steady riding rather than fast commuting. Check the published figures against your own route before you commit.
- You ride loaded and want strong climbing assist, since 120 Nm is 140% above the class median.
- You want a large battery for long days out, at 720 Wh against a median of 504 Wh.
- You can store and lift a 29.5 kg bike without difficulty and have the budget for 1944 USD.
Look elsewhere if weight or price is your first concern. A touring e-bike at the 24.9 kg and 1068 USD medians will be easier to live with and cost far less. Also look elsewhere if you need a published warranty, a listed speed class or a confirmed motor type, because this bike does not give you any of them.
