Questions people ask about the Hiboy EX9
How much does the Hiboy EX9 weigh?
The Hiboy EX9 weighs 27 kg. That is exactly the median weight for its type, so it is neither light nor heavy for a city e-bike. At 27 kg you will notice the weight when you lift it, but it is normal for this class.
How much torque does the Hiboy EX9 have?
The manufacturer does not publish torque for the Hiboy EX9. The median torque for its type is 50 Nm, but we cannot say how this bike compares. If torque matters to you, ask the manufacturer before you buy.
What speed class is the Hiboy EX9?
The speed class is not published for the Hiboy EX9. The top speed is listed as 32 km/h. That figure alone does not tell you the legal class, so check the rules where you ride.
How far does the Hiboy EX9 really go?
The manufacturer claims 50 km. Our estimate is 40 km, which is 20% below the claim. The estimate uses one reference ride for every bike: Tour assist, rolling terrain, mild weather, brisk pace, an 80 kg rider. It is not a measurement. You can adjust the inputs in the range calculator to see how your own ride might change the figure.
What does it cost to run?
The Hiboy EX9 has a 557 Wh battery and a 48 V system. The price is 1199.99 USD. Running costs depend on your electricity price and how often you charge. We do not publish a running cost figure for this bike. Use the cost calculator to work it out from your own rates.
Where it falls short
The main shortfall is battery capacity. At 557 Wh it is 11% below the class median of 624 Wh. The estimated range of 40 km is also 11% below the median of 45 km. The manufacturer claim of 50 km is 20% above our estimate. If you need to cover more distance between charges, this bike asks you to compromise.
Who should buy it
Buy the Hiboy EX9 if you want a city e-bike with a known weight and a price below the class median. It suits riders who do not need the longest range in the class. The 27 kg weight is typical, so it will feel like most city e-bikes to move around.
- You ride short daily trips and can charge often, so the 40 km estimate is enough.
- You want to spend 1199.99 USD, which is 8% below the median for this type.
- You need a bike that handles a 150 kg payload, which is the listed maximum.
Look elsewhere if you need more than 40 km between charges or if you want a battery above the class median. Also look elsewhere if you need published torque or a stated speed class. This bike does not provide those figures.
