Questions people ask about this model
How much does it weigh?
It weighs 25 kg. That is 11% below the median for its type, which is 28.1 kg. For a folding e-bike, that is on the lighter side. You still need to lift it, but it is not the heaviest folder.
How much torque does it have?
It has 65 Nm of torque. That is 20% above the median of 54 Nm. More torque helps when you start with a load or climb a slope. The motor type and rated power are not published, so you cannot compare those.
What speed class is it?
The speed class is not published. The model name includes 19.8MPH, but that is not a class rating. You should check the local rules before you buy. The top speed is also not listed.
How far does it really go?
The manufacturer does not list a claimed range. MathBikes estimates 27 km, with a band of 24 to 30 km. That estimate uses one reference ride for every bike: Tour assist, rolling terrain, mild weather, brisk pace, and an 80 kg rider. It is not a measurement. You can adjust for your own conditions with the range calculator.
What does it cost to run?
The price is 559.99 USD, which is 45% below the median of 1014 USD. Running costs depend on your electricity price and how you charge. The battery is 374.4 Wh, so each full charge uses a small amount of energy. You can work out your own cost with the cost calculator.
Where it falls short
The main shortfall is range. The estimated range is 27 km, which is 44% below the median of 48 km. That comes from the 374.4 Wh battery, which is 44% below the median of 672 Wh. If you need to go further, this bike will not do it without a charge. The low price reflects that smaller battery.
Who should buy it
Buy it if your trips are short and you want to spend less. The low price and lighter weight make it easy to own. The high torque helps with loads up to 150 kg. It folds, so you can store it in small spaces.
- You commute a short distance and can charge at both ends.
- You need a folder that fits in a small apartment or car boot.
- You want high torque for carrying loads, up to 150 kg.
Look elsewhere if you need more range. The estimated 27 km is well below the median of 48 km. Also check elsewhere if you need a published speed class or warranty, because those are not listed here. For longer trips, a bike with a larger battery will serve you better.
