Questions people ask about the BK10 PRO
How much does it weigh?
The BK10 PRO weighs 42.5 kg. That is heavy for a folding bike. The median weight for its type is 28.6 kg. You will feel the difference when lifting or carrying it.
How much torque does it have?
Torque is not listed for this bike. The median torque for folding e-bikes is 50 Nm. Without a published figure, you cannot compare hill-climbing power directly. Check with the manufacturer if torque matters to you.
What speed class is it?
It is a standard pedelec class. That means pedal assist up to 25 km/h. No throttle is fitted. You ride within typical e-bike speed limits.
How far does it really go?
The manufacturer claims 70 km. Our range calculator estimates 51 km under a reference ride. That estimate is 27% below the claim. The estimate band is 45 to 57 km. Real range depends on your weight, terrain, and assist level.
What does it cost to run?
The purchase price is 1284 USD. Running costs include electricity and maintenance. Use the cost calculator to compare. Battery replacement is not listed, so factor that in separately.
Where it falls short
The main drawback is weight. At 42.5 kg, it is 49% above the class median. That makes it hard to carry upstairs or onto a train. The bike is foldable, but folding does not make it light.
Who should buy it
The BK10 PRO is for riders who want a long estimated range and a large battery. It is not for riders who need to carry their bike often. Consider it if you store the bike at ground level and value range over weight.
- You ride long distances and want a battery above the median.
- You do not need to lift the bike regularly.
- You prefer a standard pedelec without a throttle.
Look elsewhere if you need a light folding bike. The median weight is 28.6 kg, and this bike is far above that. Also, if torque is critical for steep hills, the lack of a published figure is a concern.
