The Cyrusher XF900 Pro is a full-size mountain e-bike with a 624 Wh battery, a 750 W motor and 85 Nm of torque. It weighs 32.3 kg and costs 1199 USD. That price sits 20% below the median for its type, which is 1499 USD. The battery is the number that stands out most: at 624 Wh it is 26% below the median for its class, which is 840 Wh.
This bike suits a rider who wants a mountain e-bike with strong torque and does not need to go far on a single charge. The 85 Nm motor is 6% above the median for its type, so it should handle steep climbs well. The low price also makes it a cheaper entry point than most bikes in its class. But the small battery means you will need to plan shorter rides or charge more often.

Questions people ask about the XF900 Pro
How much does it weigh?
The XF900 Pro weighs 32.3 kg. That is 5% below the median for its type, which is 34 kg. So it is slightly lighter than a typical mountain e-bike, but still heavy enough that you will notice it when lifting or pushing.
How much torque does it have?
It has 85 Nm of torque. That is 6% above the median for its type, which is 80 Nm. More torque means better climbing and quicker acceleration from a stop.
What speed class is it?
The speed class is not published. The top speed is listed as 45 km/h. That is higher than many e-bikes, but without a speed class you cannot be sure how it is legally classified.
How far does it really go?
The manufacturer claims 80 km. The MathBikes estimate is 36 km, with a band of 31 to 40 km. That is 55% below the claim. The estimate uses a reference ride: Tour assist, rolling terrain, mild weather, brisk pace, and an 80 kg rider. It is not a measurement. To see how range changes with your own inputs, use the range calculator.
What does it cost to run?
The price is 1199 USD. That is 20% below the median for its type, which is 1499 USD. Running costs depend on your electricity price and how far you ride. You can work those out with the cost calculator.
Where it falls short
The main trade-off is range. The battery is 624 Wh, which is 26% below the median for its class. The estimated range is 36 km, which is 25% below the median for its type. So you get a lower price and more torque, but you give up distance. If you plan long rides, you will need to charge more often or carry a charger.
Who should buy it
This bike suits riders who want strong torque and a lower price, and who do not need to go far on a single charge. It also suits someone who wants a lighter-than-average mountain e-bike. The 85 Nm motor gives it an edge on climbs.
- You ride short, steep trails and want strong torque without paying a premium.
- You want a mountain e-bike that is slightly lighter than the median for its type.
- You are on a budget and can accept a smaller battery and shorter estimated range.
Look elsewhere if you need long range or a bigger battery. The 624 Wh battery and 36 km estimated range are below the median for this type. If you regularly ride more than 40 km, consider a bike with a larger battery. Also check if you need a published speed class or warranty, as those are not listed for this model.
