Intradrive GD8: motor and eight integrated gears, first eMTB and what to check before buying

The news is not another power record

The Intradrive GD8 proposes changing an eMTB's architecture: it combines electric assistance and gear selection in the same unit. Instead of a derailleur hanging beside the rear wheel, it places the gears at the centre of the bike. This alternative deserves attention for what it could simplify, not because we should declare our current drivetrain obsolete.

The specific news is the launch of the first bikes with this system, Obscur ENYX and Alutech ePelmo GD8, at Roc d'Azur 2026. This is confirmed by Intradrive's announcement. Its website announces pre-sale and first deliveries to partner brands during the fourth quarter of 2026. Pre-sale does not amount to immediate availability in a Spanish store.

This is a documentation-based analysis, not our own test. We have not measured consumption, noise or performance in the mountains. The photographs are official: the cover shows an Obscur, while several details illustrate other integrations and development builds. They should not be read as a single production specification.

Confirmed data, read correctly

The GD8 specification page lists these values. The weight is for the combined motor and gearbox; comparing it directly with a conventional motor's weight without its drivetrain would give an incomplete picture.

Memorising this table is not what matters. To compare two bikes, add battery capacity, ready-to-ride weight, tires, final gearing and after-sales service. A 700 W peak does not tell you how much assistance the system delivers at every cadence either. Our explanation of torque, power and assistance helps distinguish these quantities.

Eight gears: fewer ratios need not mean less climbing ability

The 480% range describes the span between the lowest and highest ratios. In relative terms, the extremes differ by a factor of 4.8. It does not mean 480% assistance, nor does it tell you your speed when pedalling comfortably in each gear.

To know whether a bike suits your climbs, look at the gearbox in combination with the external sprockets and wheel diameter. Two builds with the same GD8 could have different final gearing. The steps between ratios also matter: enough overall range does not guarantee each shift suits your preferred cadence.

One useful check: on a sustained climb, see whether you can maintain a natural pedalling rhythm with your usual assistance level. Then try a short steep section and a flat connecting section. Do not assess only the easiest gear at maximum assistance. The aim is to cover your route with comfortable transitions, not win an argument about how many sprockets appear in a photograph.

We do not publish an invented table of internal ratios: the public specification consulted does not detail each ratio. Before buying, request the values for the exact build and compare them with a bike you already know.

Shifting at a standstill and under load: a promise that needs testing

Intradrive claims shifting while pedalling, while coasting, at a standstill and under load. This capability appears in its System description. It could help when a tight corner leads into a steep climb and you realise too late that you are in too high a gear.

The test we would request starts simply: stop on safe terrain, select a lower gear and set off again. Then make successive shifts under moderate effort. Observe whether the shifter is predictable, whether shifting interrupts assistance and whether it requires you to change your usual technique.

The advertised automatic downshifting does not justify describing it as full autopilot. Ask what conditions activate the function, how it is configured and what control the rider retains. A brief sales explanation can hide important differences between settings or software versions.

We do not recommend turning a demonstration bike into an extreme-load endurance test. Follow the manufacturer's instructions. The real advantage would be needing less anticipation when choosing a gear without losing precision; that still needs checking on a production bike.

Chain or belt: choose the build, not a label

According to Intradrive, the GD8 supports both types of external drivetrain. That does not mean a chain-equipped bike can easily be converted to a belt. Geometry, routing through the frame, mounts and tension control must form part of an approved design.

With a chain, the gearbox replaces external gear selection but does not eliminate the chain, sprockets or all guiding components. Dirt, wear and tension still need monitoring. Fewer exposed parts do not make a bike something you can put away wet and forget.

With a belt, do not automatically carry over chain-maintenance habits. Request the appropriate cleaning, inspection and adjustment procedure. Also identify which spare to take on a remote ride and what a local workshop can fix. A promising solution for frequent use can become complicated if nobody nearby stocks its parts.

The photos show two different integrations. They help identify the architecture, not confirm that every build will have the same components. Our guide to drivetrain wear remains relevant for external elements of a version with chain.

4.5 kg in the center: what changes and what we cannot promise

Centralising gear selection changes where components sit. The interesting question is how much weight moves with the rear wheel and how much is concentrated in the frame. This needs calculating for the complete bike, including tensioning and guiding parts, not by subtracting an imaginary cassette from a motor specification.

It may open up suspension-design possibilities, but it does not prove every GD8 bike absorbs bumps better than a bike with a conventional derailleur. Kinematics, rear shock, tires, pressure and load distribution still shape handling. A different architecture does not erase a poor setup.

If weight concerns you when loading the bike into a car, ask for the actual weight in your size with battery, pedals and accessories. If it concerns you on trails, try slow manoeuvres, braking and direction changes with equivalent settings. These are different questions. No gearbox figure answers both.

Obscur ENYX and Alutech: do not confuse their versions

The first two confirmed platforms bring this technology closer to the European market, but they do not form a homogeneous range. Intradrive identifies the ENYX and the ePelmo GD8; the suffix matters because other ePelmo versions use different systems. Do not assume every bike sharing that name has the GD8.

The French Obscur ENYX product page lists a carbon frame, 150 mm of rear travel and a 160 mm fork. It combines a 29-inch front wheel with a 27.5-inch rear, a chain drivetrain and a removable 840 Wh battery. The ENYX build checked has Formula suspension and is listed from EUR 12,500.

The green Obscur on the cover has different components from that basic specification. It illustrates the physical platform, not confirmation of what EUR 12,500 includes. Nor does that French price establish a final price delivered in Spain. Request a quote stating equipment, applicable taxes, shipping, terms and delivery date.

We give neither a Spanish price nor a guaranteed range for either bike. The next useful step is to confirm where you can try one, who services its electronics and which version is actually offered. Being a European launch does not guarantee a dealer near home.

840 Wh does not reveal the GD8's energy consumption

The battery belongs to the bike and its integration: the motor does not mandate one universal capacity. Intradrive advertises different options for manufacturers. The ENYX's 840 Wh should therefore not become the assumed specification for every future GD8 model.

For planning, consider available energy and consumption on a comparable route. A new system may change how you use gears and assistance, but we do not have measured efficiency data here. We do not attribute a percentage saving to the integrated gearbox or calculate advertised range from peak power.

Ask to see battery removal, the included charger and the charge display. Check whether you can charge it where you store the bike and how you would handle a fault while travelling. See our real-world range guide to plan your route with a reserve, without substituting a catalogue figure for a measurement.

The EP8 mount does not make the GD8 a universal conversion kit

Intradrive states compatibility with the Shimano EP8 frame interface. This information is aimed primarily at bicycle manufacturers considering an integration. It does not mean you can simply remove a Shimano unit from your bike and fit the GD8.

Battery, connectors, display, controls, wiring, external drivetrain, clearances and frame approval all need addressing. Sharing a mechanical interface does not imply shared electronic protocols or an approved upgrade. A photograph of a development build is not a conversion instruction either.

If you want to keep an existing eMTB, start by asking the frame brand for documented compatibility. Without it, I would not buy parts just because the bolts look similar. This launch makes more sense as a complete-bike option than a generic conversion promise.

Maintenance and support: get answers before paying a deposit

Intradrive presents the GD8 as repairable and proposes prolonged availability of spare parts in its circular design program. It is a relevant commitment, but not a workshop fee, a guaranteed repair period or a replacement parts contract that we have checked.

We did not find a complete service schedule for each bike in the public documentation consulted. We therefore do not specify a universal oil-change interval here. Request the manual, tasks, intervals and conditions for the build you will receive. Do not improvise fluids, disassembly or internal adjustments.

• Technical support: who diagnoses the gearbox, motor, battery and controls for customers in Spain.
• Procedure: what is sent if it fails and who manages the transport.
• Replacement parts: availability of guiding components, controls and external consumables.
• Software: who updates, what is needed and how an incident is handled.
• Cost: an indicative servicing quote and written warranty terms.

The value of reduced maintenance emerges over time. A protected component may need less everyday attention, but an internal fault requires diagnostic capability. Assess both before paying a deposit.

Who should follow it and who can wait

I would follow it with interest if you frequently ride in dirty conditions, value eliminating the rear derailleur and can access a demonstration and clearly defined support. Also if you want a complete bike designed around that architecture, not merely a list of motor figures.

I would wait if your bike works well and you would replace it solely to have fewer external gears; if you need immediate delivery without a confirmed date; or if available servicing requires travel you are unwilling to undertake.

A reasonable comparison with a conventional eMTB includes total price, fit, handling, maintenance and downtime. With other integrated-gearbox systems, add final gearing and dealer experience. We do not rank performance without equivalent tests.

The GD8 deserves attention because it offers a concrete technical alternative and already identifies production bikes. It does not yet deserve an automatic win over Bosch, Avinox or Pinion. A sensible purchase begins where the announcement ends: the exact bike, a test, documentation and after-sales answers.
