Decathlon is pushing back against that compromise with a promotion on a high-end electric mountain bike, the Braih RC1-R, designed to combine big range, serious torque and long-travel suspension in one unapologetically rugged package.
A premium e-mountain bike hidden in a Decathlon promo
The Braih RC1-R is not the typical budget-friendly e-bike you might associate with Decathlon. It’s a high-spec electric mountain bike aimed at riders who already know their way around gradients, suspension settings and battery percentages.
Officially priced at €7,490, the RC1-R currently sits at €6,990 thanks to a €500 discount at Decathlon in France. That still makes it a premium machine, but one that now nudges closer to the price of big-name rivals from specialist mountain bike brands.
The Braih RC1-R combines a 1,254 Wh battery, up to 184 km of range and a 114 Nm motor, putting it firmly in the serious off-road category.
On paper, this bike is aimed at riders who want to spend all day in the hills, with enough firepower to crush long climbs and enough comfort to survive the descents.
Key numbers: range, torque and travel
For many e-MTB riders, three figures matter most: range, torque and suspension travel. The Braih RC1-R leans heavily into all three.
- Battery capacity: 1,254 Wh lithium-ion
- Claimed range: up to 184 km (R200 test protocol)
- Motor: Bafang M620, 48 V, 250 W nominal
- Maximum torque: 114 Nm
- Front suspension travel: 160 mm
- Frame: hand-built 6082-T6 aluminium
The range figure of 184 km is based on the R200 certification standard, which is a harmonised test used in the e-bike industry. Real-life range will depend on rider weight, elevation, assistance mode and tyre choice, but a 1,254 Wh battery is undeniably huge compared with the 500–750 Wh packs found on many mainstream e-MTBs.
A closer look at the powertrain
The Braih RC1-R uses Bafang’s M620 mid-drive motor. On paper it respects EU rules by being limited to 250 W of continuous power and a top speed of 25 km/h with assistance. Where it flexes is in torque: 114 Nm is substantial, especially for steep, technical climbs.
The Bafang M620 delivers 114 Nm of torque, giving punchy support on brutal gradients without feeling like it’s about to stall.

That torque figure puts it up against, and in some cases ahead of, systems from Bosch, Shimano and Brose that typically hover in the 75–90 Nm range. Riders who regularly tackle rocky climbs or forestry access roads will feel the difference when pulling away or grinding up sustained inclines.
The 48 V architecture helps keep current lower for the same power output, which can reduce heat and improve efficiency under long, heavy loads. For riders, that translates into more consistent support on marathon ascents rather than a system that fades or throttles back too early.
Hand-built aluminium frame and serious suspension
While carbon frames grab headlines, the RC1-R sticks with a meticulously built aluminium chassis. The frame uses 6082-T6 aluminium, a high-strength alloy commonly found in demanding industrial applications. According to Braih, each frame is hand-made in Barcelona.
This choice points to a bike designed for durability and serviceability. Aluminium tolerates knocks and shuttle dings without the same paranoia about hidden damage that can accompany carbon.
On the suspension side, the spec reads like a gravity-leaning trail bike:
| Component | Model | Key features |
|---|---|---|
| Fork | FASTACE ALX13RC Coil | 160 mm travel, adjustable compression and rebound |
| Rear shock | FASTACE BDA53RC | Adjustable compression and rebound |
A coil fork, rather than air, suggests a focus on sensitivity and consistency. Coil units tend to offer a supple initial stroke and predictable performance on long descents, at the cost of slightly more weight and less easy adjustability compared with air.
With 160 mm of travel up front and a matching rear setup tuned around off-road use, the RC1-R is aimed at everything from rugged forest singletrack to rocky fire roads, rather than light gravel paths.
Tech features: screen, connectivity and lighting
The Braih RC1-R is not just about raw mechanical components. It brings a few modern conveniences for riders who want data and control on their bars.
The bike mounts a colour LCD display that shows speed, battery level, assistance mode and trip data. Bluetooth connectivity ties into the Bafang Go smartphone app, giving access to additional ride statistics, potential firmware updates and fine-tuning options specific to the motor system.
Integrated LED lights and Bluetooth-connected controls make the RC1-R suited to long days that start at dawn and end after dark.
Integrated LED lighting is a useful addition for riders who head out early, finish late or simply want extra safety on stretches of road between trails. Built-in lights mean one less accessory to charge and strap onto the bike.
Who this electric MTB is really for
The Braih RC1-R is aimed at demanding off-road riders rather than casual Sunday cyclists. The price alone makes that clear, but the specification underlines it.
There’s enough battery here for all-day mountain missions with heavy use of higher assistance modes. The motor can push a loaded rider up steep climbs without constant gear-hunting. The suspension is clearly tuned for rough terrain rather than city bike paths.
Potential buyers are likely riders who already own a non-assisted mountain bike and now want to extend their range and ride time, or older riders who still want to tackle big days in the hills without burning through their legs on each ascent.
Range in real life: what 184 km could look like
That headline 184 km autonomy can be hard to translate into day-to-day use. Here are a few possible scenarios for a rider around 80 kg with a backpack and off-road tyres:
- Eco-heavy ride: 120–150 km of mixed trail and forest roads with assistance mostly in low mode, saving power for steeper climbs.
- Sporty mountain loop: 70–100 km with frequent use of mid and high assistance to clear big elevation gains.
- Bikepacking weekend: 60–80 km per day over two to three days if you’re careful with modes and route choice.
These are estimates, but they show how a 1,254 Wh battery opens up options that standard 500–625 Wh bikes have to manage carefully, especially in mountainous terrain.
Terms and tech details worth understanding
For anyone new to e-MTB jargon, a few terms on the spec sheet deserve clarification:
- Wh (watt-hours): This is the energy capacity of the battery. More Wh means you can draw the same power for longer.
- Nm (newton metres): This measures torque. Higher numbers help when starting on steep slopes or hauling heavier loads.
- R200 certification: A lab-based method that aims to standardise range claims across e-bikes. It doesn’t reflect every rider or terrain, but it allows rough comparison between models.
- Coil vs air suspension: Coil is often plusher and more consistent, while air is lighter and easier to adjust for different rider weights.
Benefits and trade-offs of such a powerful e-MTB
A bike like the Braih RC1-R brings clear advantages: long autonomy, strong uphill support and serious off-road capability. For riders who live near mountains or big trail networks, it can turn once-a-month epic rides into a regular habit.
There are trade-offs though. The large battery and robust frame add weight; manoeuvring the bike in tight urban spaces or lifting it onto a car rack can be demanding. The price lands firmly in enthusiast territory, especially once you factor in quality helmet, pads and potentially a second charger.
The RC1-R isn’t built for quick errands to the bakery; it’s built for riders who think in elevation gain and singletrack, not cycle lanes.
That being said, for anyone eyeing big mountain days, regular alpine trips or off-road bikepacking, the combination of 184 km claimed range, 114 Nm of torque and a hand-built frame makes Decathlon’s promotion on the Braih RC1-R a notable entry in the high-performance e-MTB space.
