The isinwheel EB3 carries a 504 Wh battery, which is 30% below the median for commuter e-bikes in our database. That single figure shapes most of what follows. It is a commuter e-bike with a 250 W rated motor, a 27 kg frame and a price of 0 USD in our data.
You get a bike built for short, regular trips rather than long ones. The 45 Nm of torque is 40% below the median for its type, so expect modest help on climbs. It suits a rider who wants a simple commuter and does not need to cross a city in one charge. Read the numbers before you decide.
What the numbers say
| Spec | This bike | Median for its type |
|---|---|---|
| Battery | 504 Wh | 720 Wh |
| Weight | 27 kg | 27.7 kg |
| Torque | 45 Nm | 75 Nm |
| Estimated range | 37 km | 52 km |
| Price | 0 USD | 1699 USD |
The table shows one clear strength and several gaps. Weight is close to the median, just 3% below it. Battery, torque and estimated range all sit well under the class median. Price is not comparable, because the figure in our data is 0 USD.
Questions people ask about this model
How much does it weigh?
The isinwheel EB3 weighs 27 kg. That is 3% below the median of 27.7 kg for commuter e-bikes in our database. The difference is small, so treat this as an average-weight commuter rather than a light one. You will feel the weight when you lift it onto a rack or carry it up steps.
How much torque does it have?
The motor delivers 45 Nm of torque. That is 40% below the median of 75 Nm for its type. Lower torque means less assistance on steep climbs and when you start from a stop with a load. The rated power is 250 W, with a peak of 750 W.
What speed class is it?
The speed class is not published. The top speed is listed as 25 km/h. We cannot tell you which legal class that maps to, because the brief does not state it. Check with the seller before you buy if class matters where you ride.
How far does it really go?
The manufacturer claims 100 km. Our estimate is 37 km, with a band of 32 to 41 km. That is 63% below the claim. The estimate comes from one published formula, not a ride: battery capacity divided by consumption under a reference ride of Tour assist, rolling terrain, mild weather, brisk pace and an 80 kg rider. You can run your own figures through the range calculator.
Against its class, the estimated range is 29% below the median of 52 km. Plan for short commutes and charge often. The battery voltage is 48 V, and charge time is not published.
What does it cost to run?
We cannot give a running cost, because the price in our data is 0 USD and charge time is not listed. Both figures are needed for a fair estimate. The battery is 504 Wh, so each full charge moves a known amount of energy, but we will not put a number on it without the missing inputs. Use the cost calculator once you have the real price and your local electricity rate.
What else is not published?
Several basics are missing from the brief. The motor type, throttle, step-through frame and warranty are all not listed. The bike is not foldable and not cargo capable. Ask the seller for these before you commit.
Where it falls short
The main trade-off is range against the claim. The isinwheel EB3 lists 100 km, but our estimate is 37 km, a gap of 63%. Its 504 Wh battery is 30% below the class median, and its 45 Nm motor is 40% below the median. You are buying a lighter-duty commuter, and the numbers say so plainly.
Weight is the one place it holds its ground, at 27 kg against 27.7 kg. That is a small gain for a large loss elsewhere. If range or climbing matters to you, this is not the strongest choice in its class.
Who should buy it
Buy the isinwheel EB3 if your trips are short and your terrain is mostly flat. The 37 km estimate covers a few days of short commuting for many riders. The 150 kg maximum payload is generous for a bike of this weight.
- You ride a short, flat commute and can charge at both ends of the trip.
- You want a commuter near the class median weight of 27.7 kg, at 27 kg.
- You need a high payload limit, and 150 kg covers you.
Look elsewhere if you need long range or strong climbing help. The 37 km estimate and 45 Nm torque will not suit a hilly route or a rider who wants to skip charging. Compare it with bikes nearer the 720 Wh and 75 Nm medians before you decide.
