The Duotts APEFOX RH20 is a folding e-bike with a 1080 Wh battery. That capacity is 67% above the median for its type, which is 648 Wh. It also weighs 37.5 kg, which is 33% above the median of 28.1 kg. So this is a big-battery folder that trades portability for range.
You get a 750 W rated motor and a 48 V system. The estimated range is 77 km, 64% above the class median of 47 km. That makes it suited to riders who want long assisted rides and do not need to carry the bike up stairs. It is less suited to mixed-mode commuting where you fold and lift the bike often.

Questions people ask about the Duotts APEFOX RH20
How much does the Duotts APEFOX RH20 weigh?
It weighs 37.5 kg. That is 33% above the median for folding e-bikes, which is 28.1 kg. The weight comes with the large battery, so expect a heavy lift when folded.
How much torque does it have?
Motor torque is not listed for this bike. The median torque for its type is 50 Nm, but we cannot compare because the figure is missing. If torque matters to you, ask the seller for it before you buy.
What speed class is it?
The speed class is not listed. Top speed is also not published. Without those figures, you cannot know how fast it will assist or whether it is restricted.
How far does it really go?
The manufacturer does not list a claimed range, so there is nothing to compare. Our estimated range is 77 km, with a band of 67 to 86 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. Use the range calculator to see how your own weight and route change the figure.
What does it cost to run?
The battery is 1080 Wh, or 22.5 Ah at 48 V. A full charge takes just over one kilowatt hour of electricity. The exact cost depends on your tariff, which we do not have. You can work it out with the cost calculator. The purchase price is 1187 USD, which is 11% above the median of 1068 USD.
Where it falls short
The main drawback is weight. At 37.5 kg, this bike is 33% heavier than the median folder. That makes it hard to carry when folded, and it may be awkward on public transport or up stairs. The large battery gives you range, but it also adds mass. You are trading portability for distance.
Who should buy it
This bike suits riders who want long assisted rides and rarely fold it. The big battery and high estimated range make it a good choice for commuting or touring where you can store it on the ground. It also fits if you have a secure place to park and do not need to carry it.
- You want a folding e-bike with a large battery for long rides and you do not need to lift it often.
- You have a ground-level storage spot and want to avoid public transport.
- You are willing to pay 1187 USD, which is 11% above the median, for the extra range.
Look elsewhere if you need to carry the bike up stairs or on trains. At 37.5 kg, it is not a light folder. Also consider other options if you need published torque, top speed, or warranty details, because those are not listed here.
