For years, the basic layout of an electric mountain bike has remained surprisingly familiar.
There is a mid-drive motor around the bottom bracket.
There is a cassette on the rear wheel.
There is a derailleur hanging beside it.
And there is a chain connecting everything together.
Motors have become lighter and more powerful. Batteries have become more energy-dense. Software has become smarter.
But the basic drivetrain architecture has barely changed.
The Gobao X1P suggests that this may finally be changing.
First shown at Eurobike 2026, the X1P combines a powerful eBike motor and an electronically controlled continuously variable transmission — or eCVT — inside a single drive unit.
Now that technology is moving from a trade-show display into a real electric mountain bike.
German bike manufacturer Alutech has officially announced the ePelmo X1P, an aggressive 170 mm Enduro eMTB designed specifically around Gobao's new drive system.
And this bike may tell us something important about where the next generation of eMTBs is heading.
What Is the Gobao X1P?
The Gobao X1P is not simply another high-torque mid-drive motor.
It combines two systems that are traditionally separated on a mountain bike:
the electric motor and the transmission.
Inside the X1P drive unit is an electronically controlled continuously variable transmission.
That means the bike no longer needs a conventional cassette and rear derailleur to create different gear ratios.
Instead, the X1P provides a claimed 500% gear range within the drive unit itself.
Its headline specifications include:
| Specification | Gobao X1P |
|---|---|
| Maximum torque | 150 Nm |
| Peak power | Up to 1,500 W |
| Drive unit weight | 3.85 kg |
| Gear range | 500% |
| Transmission | Integrated eCVT |
| Drive | Gates belt compatible |
| Maximum cadence | Over 120 rpm |
| Housing | Magnesium |
| EU-oriented assist version | 25 km/h |
Those numbers are impressive.
But the torque figure may actually be the least interesting part of the X1P.
The bigger story is the transmission.
Motor + Gearbox: Why Does It Matter?
A conventional full-power eMTB normally has several exposed drivetrain components:
- Chain
- Cassette
- Rear derailleur
- Derailleur hanger
- Shifter
- Motor
The X1P changes that architecture.
The gear ratios are handled inside the central drive unit, while a belt can transfer power to the rear wheel.
That means the cassette and rear derailleur can disappear completely.
For an eMTB, that has some potentially important advantages.
1. No Rear Derailleur Hanging Beside the Wheel
Anyone who regularly rides technical mountain bike trails understands how vulnerable a rear derailleur can be.
Rocks, crashes, branches and impacts can damage the derailleur or hanger.
Moving the transmission into the center of the bike removes one of the most exposed mechanical components from the rear wheel.
That could be especially interesting for:
- Enduro eMTBs
- Downhill-oriented eMTBs
- Bike park riding
- Rental fleets
- High-mileage electric bikes
2. A Belt Can Replace the Chain
The Alutech ePelmo X1P uses a Gates belt drive instead of a traditional bicycle chain.
For normal mountain bikes, belt drives have always been difficult to combine with conventional derailleur systems.
An integrated gearbox changes that.
Without a cassette and rear derailleur, the rear wheel only needs to receive power.
The belt can therefore become a realistic option.
Compared with an exposed chain drivetrain, a belt potentially offers a cleaner and lower-maintenance solution.
For electric mountain bikes — where powerful motors place considerable load on chains, cassettes and chainrings — that is particularly interesting.
What Does eCVT Mean on an eBike?
CVT stands for Continuously Variable Transmission.
Unlike a conventional 12-speed drivetrain with twelve fixed gear ratios, a continuously variable transmission can move progressively through a range of ratios.
Gobao's system is electronically controlled, creating an eCVT.
Instead of asking:
"Should I be in gear 5 or gear 6?"
the system can continuously select a ratio based on riding conditions.
Depending on the operating mode, factors such as:
- Pedaling cadence
- Bike speed
- Motor load
- Rider input
- Gradient
can be used to determine the appropriate ratio.
The system can therefore attempt to maintain a preferred cadence automatically.
There is also a manual mode for riders who prefer more direct control.
What Could Automatic eCVT Feel Like on the Trail?
Imagine climbing a technical section of trail.
With a traditional drivetrain, you may need to anticipate the climb, reduce pedal pressure and shift into an easier gear.
Shift too late under heavy motor torque and the drivetrain can make an unpleasant mechanical sound.
With an electronically controlled continuously variable transmission, the concept is different.
The system can continuously change the transmission ratio while the rider keeps pedaling.
In theory, that could make technical climbing much simpler:
pedal — steer — choose your line — let the transmission manage the ratio.
There are no traditional gear steps to move through.
That could fundamentally change the interaction between rider, motor and drivetrain.
However, specifications alone cannot tell us whether the system will feel natural.
Real-world trail testing will ultimately determine how well Gobao has calibrated:
- Cadence control
- Ratio changes
- Rider input
- Motor response
- Efficiency
- Noise
- Heat management
That is why the first production bikes matter so much.
The First Real Bike: Alutech ePelmo X1P
At Eurobike 2026, the Gobao X1P attracted plenty of attention.
But there was an obvious question:
Who would actually build a production eMTB around it?
We now have the first clear answer.
German manufacturer Alutech has announced the ePelmo X1P.
This is significant because Alutech did not simply install the motor into an existing frame.
The company redesigned large parts of the bike around the X1P system and its belt drivetrain.
It even developed its own belt tensioning solution.
The result is an Enduro-focused electric mountain bike with:
- Gobao X1P motor and eCVT
- 150 Nm maximum torque
- Up to 1,500 W peak power
- 500% transmission range
- Gates belt drive
- Removable 750 Wh battery
- 170 mm front travel
- 170 mm rear travel
- 29 / 27.5-inch mullet option
- Four frame sizes
- ASTM Category 5 classification
The first Launch Edition is limited to 50 bikes, with initial customer deliveries expected in spring 2027.
In other words, X1P is no longer just a Eurobike concept.
It is becoming a commercial drivetrain platform.
The Battery Is Almost as Interesting as the Motor
The ePelmo X1P uses Gobao's removable 750 Wh battery.
The battery weighs approximately 3.6 kg.
But the more unusual specification is charging.
Gobao's high-output charging system is designed to charge the battery dramatically faster than the typical eBike charger.
This matters because battery capacity is not the only way to solve range anxiety.
There are two approaches:
carry more energy
or
recharge energy faster.
Most eMTBs have historically followed the first approach, with batteries growing from around 500 Wh to 600, 700, 800 Wh and beyond.
Very fast charging could create another option.
For bike parks, rental operations, Enduro events or riders doing multiple sessions in one day, fast charging may eventually become just as important as battery capacity.
Gobao X1P vs DJI Avinox: Are They Really Competitors?
Since Eurobike, the Gobao X1P has frequently been discussed alongside the DJI Avinox system.
The comparison makes sense.
Both companies are challenging the established eMTB drive-system market with unusually powerful, highly integrated systems.
But their approaches are very different.
DJI Avinox focuses heavily on achieving an exceptional combination of:
- Low motor weight
- High power
- Smart assistance
- Battery integration
- Connectivity
Gobao is taking another route with the X1P.
Its key proposition is:
motor + transmission + intelligent control in one central unit.
So this is not simply a torque competition.
The more interesting question is which architecture makes more sense for future electric mountain bikes.
A conventional drivetrain with an extremely advanced lightweight motor?
Or a heavier central unit that removes the external transmission almost entirely?
We do not have the answer yet.
But that competition could make the next few years of eMTB development very interesting.
Gobao Has Another Trick: P100 and P120
The X1P may be Gobao's most technologically unusual product, but another Gobao strategy could be equally important to bike manufacturers.
At Eurobike 2026, Gobao also presented the P100 and P120 drive units.
These motors use a mounting architecture designed around the widely used Shimano EP-series layout.
Why does that matter?
Developing a new carbon or aluminium eMTB frame around a completely new motor is expensive.
It can require:
- New frame molds
- New motor brackets
- New battery packaging
- New cable routing
- New prototypes
- Structural testing
- Suspension redesign
- Production tooling
A compatible motor architecture can reduce part of that development barrier.
A bike manufacturer that already understands this frame layout could potentially develop a Gobao-powered platform without starting entirely from zero.
There is an important distinction, however:
physical motor compatibility does not mean electronic compatibility.
A Gobao conversion still requires the appropriate Gobao ecosystem, including components such as the battery, controls, wiring and display.
That distinction matters.
Gobao Is Not Trying to Sell Only a Motor
This may ultimately be the most important part of Gobao's strategy.
Gobao increasingly looks less like a traditional component supplier and more like an eBike technology platform provider.
For OEM bicycle manufacturers, the company can provide an ecosystem including:
- Drive unit
- Battery
- Charger
- Display
- Controller
- Wiring
- Connectivity
- Smartphone App
- System customization
- Frame integration support
That puts Gobao into a broader competition.
The modern eBike market is increasingly not:
motor company vs motor company.
It is:
ecosystem vs ecosystem.
Bosch has an ecosystem.
Shimano has an ecosystem.
Bafang has an ecosystem.
DJI Avinox has an ecosystem.
And Gobao clearly wants one too.
Why This Matters for Smaller eBike Brands
For large bicycle manufacturers, developing a proprietary electric platform is possible.
For smaller brands, the economics are very different.
Creating everything independently — motor integration, batteries, displays, software, connectivity and service tools — requires enormous investment.
A complete OEM system allows a smaller eBike manufacturer to focus resources elsewhere:
- Frame geometry
- Carbon engineering
- Suspension layout
- Component selection
- Product positioning
- Customization
- Distribution
- Customer service
This is one reason open and semi-open motor ecosystems matter.
They can allow smaller bicycle companies to develop competitive products without needing to become motor and software companies themselves.
From Bafang to Gobao: Chinese eBike Systems Are Changing
For international riders, Chinese eBike motors were once mainly associated with affordable high-power systems.
That description is becoming increasingly outdated.
The new generation of Chinese drive systems is competing in areas such as:
- Power-to-weight ratio
- Torque sensing
- Integrated displays
- Mobile connectivity
- Fast charging
- Electronic shifting
- Automatic transmission
- OEM customization
- Complete system integration
Bafang has already demonstrated how a Chinese manufacturer can become a global eBike system supplier.
DJI changed expectations again when Avinox entered the high-end eMTB market.
Now Gobao is approaching the problem from another direction.
Competition between these companies could accelerate eMTB development considerably.
Does an Integrated Gearbox Make Sense for an eMTB?
There are compelling reasons why it might.
Potential Advantages
An integrated motor gearbox could offer:
- Fewer exposed drivetrain components
- No rear derailleur
- No conventional cassette
- Belt-drive compatibility
- Centralized drivetrain weight
- Automatic gear ratio management
- Reduced drivetrain maintenance
- Better protection from crashes and trail debris
But the technology also creates new questions.
Questions That Still Need Answers
We still need long-term independent testing to understand:
- Gearbox durability
- Belt durability under high motor load
- Real-world efficiency
- Noise
- Heat management
- Service intervals
- Replacement cost
- Spare-parts availability
- Software reliability
- International service support
This is important.
A revolutionary specification sheet does not automatically create a great mountain bike.
Trail performance and long-term ownership will decide whether the technology succeeds.
What Could the Future eMTB Look Like?
The traditional image of a mountain bike drivetrain may eventually change.
Today we expect to see:
motor + chainring + chain + cassette + derailleur
Tomorrow, more high-performance electric mountain bikes could look like:
motor + gearbox + belt + rear pulley
That would fundamentally change both bicycle design and maintenance.
Rear suspension designers would have fewer drivetrain components to package around.
Rear wheels could become mechanically simpler.
Drivetrain components could become less vulnerable to impacts.
Software could play a much larger role in determining cadence and gearing.
And instead of choosing between 10-speed, 11-speed or 12-speed drivetrains, riders may eventually choose how they want the bike to manage cadence.
That is a much bigger change than simply adding another 20 Nm of motor torque.
What This Means for 4LEAF and Custom eMTB Development
At 4LEAF Bikes, we closely follow the development of new eMTB drive systems because the motor is no longer an isolated component.
Motor architecture influences the entire bike:
- Frame structure
- Battery packaging
- Suspension layout
- Chainstay design
- Cable routing
- Cooling
- Weight distribution
- Component compatibility
Our current electric mountain bike platforms use established Bafang systems such as the M820, M510, M560 and M620 because they provide different solutions for lightweight trail bikes, full-power eMTBs and high-torque platforms.
But the emergence of systems such as the Gobao X1P illustrates where the industry may be heading next.
For riders, dealers and small bicycle brands, the important question is becoming less:
"Which motor is the most powerful?"
and more:
"Which drive-system architecture best fits the bike we want to build?"
That is a much better question.
Final Thoughts
The Gobao X1P is interesting because it represents more than another powerful eBike motor.
Its 150 Nm torque and 1,500 W peak output will attract attention, but the integrated eCVT may prove far more important.
By moving the transmission into the central drive unit, removing the conventional cassette and derailleur, and enabling belt drive, Gobao is challenging one of the most established design conventions in mountain biking.
The Alutech ePelmo X1P gives us the first serious opportunity to see that concept move from an exhibition stand toward real-world production.
Whether integrated motor-gearbox systems eventually become mainstream remains uncertain.
But one thing is becoming clear:
the next big eMTB battle may not be about who builds the strongest motor.
It may be about who builds the best complete drive system.
