Apefox RH20 Review:

A Surprisingly Powerful Dual-Motor Fat-Tire E-Bike

FI’m BK42, and this is the new Apefox RH20 — a bike that genuinely surprised me.

At first glance, the RH20 looks like another big, aggressive fat-tire e-bike. But after spending time riding and testing it, I found there’s quite a bit more to this bike than its appearance suggests.

In this review, I’ll cover the real pros and cons, who the RH20 is actually designed for, how it performs in the real world, whether it’s worth the money, and — most importantly — whether it’s the right e-bike for you.
And if you decide it is, I also have a €100 discount code that can bring the price down to €999.

Let’s get started.

Two 750W Motors: The RH20 Means Business

The RH20 is still relatively new to the e-bike market, but Apefox is part of the Duotts group, a company already known for producing powerful dual-motor e-bikes.
That heritage is immediately apparent when you look at the RH20’s specifications.

The bike comes equipped with two 750-watt motors, with each motor producing 65 Nm of torque. They’re surprisingly quiet, and interestingly, there’s no obvious branding on the motors themselves.

For the EU version, the bike arrives configured with only the rear motor active by default, while the speed is limited to 25 km/h.

However, there’s another mode available.
There isn’t a dedicated front-motor button. Instead, you activate both motors by pressing and holding the Power and Minus buttons simultaneously until the motor icon stops blinking.

And when both motors kick in, the RH20 changes character completely.

One Motor Is Already Plenty

For most of my testing, I used the rear motor only.
I weigh around 78 kg, and because I live in a relatively flat city, I honestly couldn’t find a hill that really challenged the rear motor.

With one motor, acceleration is smooth and predictable. It’s powerful enough for normal city riding without feeling unnecessarily aggressive.
But activate the second motor and things get much more interesting.

At PAS level 5, with the higher speed setting enabled, acceleration becomes explosive. There’s enough power that the front wheel can even spin briefly before finding traction.
That’s when the RH20 starts feeling less like a conventional commuter e-bike and more like a small electric tank.

The Throttle Isn’t Quite What You Might Expect

The RH20 also comes with an optional half-twist throttle.
There’s an important catch, though: the throttle only works while you’re pedaling.

It provides a strong boost when starting off, but you can’t simply sit back and use the throttle as a standalone electric motorcycle control.
For some riders, that’s a positive feature. For others, it may be disappointing.

It’s also worth remembering that running both motors has a noticeable effect on battery consumption. That’s one of the main reasons I spent most of my testing time using the rear motor alone.

Battery and Real-World Range

One of the RH20’s biggest strengths is its battery.
You get a substantial 48V 22.5Ah removable battery, which can be charged either on the bike or separately.

The charging system requires the key to be in the ON position, something worth knowing if the bike initially appears not to be charging.

I couldn’t find reliable information about the manufacturer of the battery cells, so I wouldn’t make any assumptions about the individual cell brand.
What matters more is how the battery performs in the real world.

Almost 60 Kilometers on a Charge

For my range test, I rode primarily in PAS level 5 with very little pedal assistance.

The result?
I managed almost 60 kilometers on a single charge.

That was one of the biggest surprises of the entire test.
Apefox advertises a maximum range of up to 100 kilometers, but I’d treat that figure as an ideal-condition estimate.

To get anywhere near 100 km, you’d likely need to ride at lower PAS levels, pedal significantly more, and have favorable terrain, weather, rider weight, and speed.

For a 40 kg fat-tire e-bike with dual-motor capability, getting nearly 60 km in demanding real-world conditions is still impressive.
A full recharge takes approximately 8 hours.

Controls and Equipment

The RH20 has a fairly straightforward control layout.
On the left side of the handlebar, you’ll find the display controls, front brake lever and a small bell.

In the center sits the color display, along with a USB charging port.
On the right are the Shimano gear shifter, rear brake lever and optional half-twist throttle.

The high BMX-style handlebar adds to the upright and comfortable riding position.
But the RH20 isn’t just about the motor and battery.

It also comes with:
– Aluminum mudguards
– A rear rack rated for 25 kg
– Integrated front and rear lights
– Rear brake light functionality

The rear light doubling as a brake light is a particularly useful touch if you’re riding in traffic.

Is the Apefox RH20 Legal?

This is probably the most complicated part of the RH20 discussion.
The bike is supplied in an EU configuration with a 25 km/h speed limit and no active throttle, designed to comply with EU e-bike requirements.
However, the RH20’s dual-motor capability and available settings make the legal situation more complicated.

If you change the speed settings and activate both motors, you shouldn’t automatically assume that the bike continues to qualify as a standard EU pedelec.
And this isn’t simply about whether the police might stop you.

There can also be consequences relating to insurance, liability and accidents if you’re riding a bike on public roads in a configuration that doesn’t meet the applicable legal requirements.

The rules also vary between countries.
So before changing the bike’s settings or using a modified configuration on public roads, make sure you understand the regulations that apply where you live.

More power isn’t necessarily more legal.

Comfort, Sizing, and Everyday Practicality

So, after spending time with the bike, who would I recommend it to?
For me, the RH20 makes the most sense for adventure riders, off-road enthusiasts and anyone looking for a seriously capable fat-tire e-bike.
It’s particularly interesting for people who want:
– Lots of motor power
– Long battery range
– Excellent traction
– A comfortable ride over rough terrain
– High cargo capacity
– The flexibility of a folding frame

It could also make sense for professional or private applications where the higher-power configuration is legally permitted.

But I wouldn’t recommend it simply because you want a lightweight city commuter.
There are much lighter and more practical options for that.
The RH20 is big, powerful and impossible to ignore.

People will notice you riding it.

Final Verdict: Is the Apefox RH20 Worth It?

The Apefox RH20 genuinely surprised me. I expected a big, powerful fat-tire e-bike, and that’s exactly what it is. But the combination of range, comfort, braking performance, build quality and motor power makes it more impressive than I initially expected.

The biggest compromise is undoubtedly the weight.
At 40 kg, this isn’t an e-bike I’d want to carry upstairs every day. The non-folding handlebar is another limitation if you’re looking for something particularly easy to transport.

But once you’re riding, the RH20 makes a lot more sense.
The fat tires and suspension provide a comfortable ride, the rear motor is already more than powerful enough for everyday use, and the dual-motor system gives you an entirely different level of performance when you need it.

For an adventure rider or someone looking for a powerful, distinctive fat-tire e-bike without spending a fortune, the RH20 is definitely worth considering.

Price and Discount

Apefox sent me the RH20 for testing, and I also created a step-by-step assembly video to help with putting the bike together.
Importantly, Apefox does not review or approve my videos, and I’m free to share my honest opinion — including the things I don’t like about the bike.

The Apefox RH20 is available for €999 when you use the code BK42RH20 at the link below.
The bike is available in green, includes free shipping, and comes with a 2-year warranty.

So, is it the right bike for you?
If you’re looking for a lightweight commuter, probably not.

But if you want a powerful, comfortable, rugged fat-tire e-bike with serious off-road potential, the Apefox RH20 could be a very interesting option.
And at €999 with the BK42 discount, it’s certainly a bike I’d take a serious look at.
