The isinwheel EB1S Compact is a folding e-bike with a 432 Wh battery. That is 36% below the median for its type, which is 672 Wh. The low capacity keeps the price at 0 USD, but it also limits how far you can go.
This bike suits short trips and mixed commutes. You can fold it and carry it onto public transport. It weighs 24 kg, which is 15% below the median of 28.1 kg. That makes it easier to lift than many folding e-bikes, but it is still a heavy object.
What the numbers say
| Spec | This bike | Median for its type |

The table shows the EB1S Compact is lighter than average but has less battery and less estimated range. Torque is not published, so you cannot compare it. Price is 0 USD, which is far below the median of 1049 USD. That low price is the main reason to consider it.
What people ask about this model
How much does it weigh?
It weighs 24 kg. That is 15% below the median for folding e-bikes. You can lift it, but it is not light. Use the weight figure when you plan to carry it up stairs or onto a train.
How much torque does it have?
The manufacturer does not list torque. The median for this type is 50 Nm, but that does not tell you this bike's torque. Without a published figure, you cannot judge its climbing ability from specs alone.
What speed class is it?
The speed class is not published. The top speed is 25 km/h. That is a common limit for e-bikes in many regions. Check your local rules before you buy.
How far does it really go?
The manufacturer claims 50 km. The MathBikes estimate is 31 km, which is 38% below the claim. That estimate comes from a formula, not a test ride. It uses battery capacity and a reference ride: Tour assist, rolling terrain, mild weather, brisk pace, and an 80 kg rider. Use the range calculator to see how your own weight and route might change it.
The estimated range is also 35% below the median of 48 km for this type. So even the estimate is short compared with other folding e-bikes. Plan for short trips and charge often.
What does it cost to run?
The price is 0 USD. That is not a typo. It is far below the median of 1049 USD. Running costs depend on electricity prices where you live, which we do not list. Use the cost calculator to work out your own costs.
The battery is 432 Wh. Charging it from empty takes some electricity, but we do not publish a cost per charge. The low purchase price is the main financial advantage.
Where it falls short
The main drawback is range. The estimated range is 31 km, which is 35% below the median for folding e-bikes. The battery is 432 Wh, which is 36% below the median. If you need to go further than about 31 km on a charge, this bike will not suit you. The low weight helps, but it does not make up for the small battery.
Who should buy it
Buy this bike if you want a folding e-bike for short trips and you value low weight and low price over range. It suits mixed commutes where you fold the bike for part of the journey. It does not suit long distances or cargo.
- You commute a short distance and can charge at both ends.
- You need to fold the bike to take it on public transport or store it in a small space.
- You want to spend as little as possible on an e-bike.
Look elsewhere if you need more than about 31 km on a charge. Look elsewhere if you need to carry cargo, because this bike is not cargo capable. Look elsewhere if you need a published torque figure or warranty details, because those are not listed.
