Questions people ask
How much does it weigh?
The X7 PRO weighs 43 kg. That is 50% above the median for folding e-bikes. You will feel the weight when lifting or carrying it.
How much torque does it have?
Torque is not listed for this bike. Many hub motors have lower torque than mid-drives. Without a published figure, you cannot compare it directly.
What speed class is it?
It is a standard pedelec class. That means pedal assist up to 25 km/h. No throttle is included.
How far does it really go?
MathBikes estimates 84 km on a reference ride. That ride uses tour assist, rolling terrain, mild weather, brisk pace, and an 80 kg rider. The manufacturer claims 80 km, so the estimate is 5% below the claim. Use the range calculator to adjust for your conditions.
What does it cost to run?
The price is 1284 USD, which is 20% above the median for its type. Running costs depend on electricity and maintenance. Use the cost calculator to compare long-term costs.
Where it falls short
The X7 PRO is heavy. At 43 kg, it is 50% above the median weight. That makes it hard to carry up stairs or onto a train. The battery is large, but the weight is a trade-off.
Who should buy it
This bike fits riders who want maximum range from a folding model. It also suits those who do not need to carry the bike often. If you park it at home and ride from there, the weight is less of an issue.
- You ride long distances and want a battery that lasts.
- You have a place to store a heavy bike without lifting it.
- You prefer a standard pedelec without a throttle.
Look elsewhere if you need a light folding bike for commuting. The 43 kg weight will be a burden. Also, if you need torque for steep hills, the lack of a published figure is a warning.
