2027 Whyte Karve RSX Avinox Electric Mountain Bike – Gun Metal
Exhilaration Everywhere
The Whyte Karve RSX is a premium full-power electric mountain bike built for riders who want to climb harder, descend faster and make every ride count.
At its heart is the remarkable Avinox M2S drive system, delivering up to 150Nm of maximum torque and 1,300W of peak power. Its headline figures are immense, but it’s the smooth, responsive and controllable way the assistance is delivered that makes the real difference on technical terrain.
Power arrives precisely when it’s needed, helping the rear tyre maintain grip on steep, loose and awkward climbs without making the bike feel unpredictable.
Add a full-carbon frame, 160mm of custom-tuned Fox Factory suspension, SRAM AXS electronic shifting, SRAM Maven Silver brakes, DT Swiss Hybrid wheels and a large 800Wh battery, and the result is a seriously capable e-MTB with the specification to match its performance.
Why Choose the Whyte Karve RSX?
The Karve RSX is for riders who don’t want to compromise between climbing assistance, descending capability and engaging trail handling.
While the Avinox motor supplies the power, Whyte’s geometry and Quad-Link 4 suspension ensure the Karve RSX still feels like a proper mountain bike.
Its proportional geometry, size-specific rear centres and custom suspension tuning help keep the rider balanced across all four frame sizes. The result is predictable handling, confident cornering and a planted feel when the terrain becomes steep, rough or fast.
At 22.9kg in size Large, the Karve RSX combines a full-power motor and 800Wh battery with a weight that helps retain responsive, agile handling.
The Premium Karve Build
The RSX sits at the premium end of the 160mm Karve range and adds equipment chosen for riders who want maximum performance straight out of the box:
- Full-carbon mainframe and rear triangle
- Factory-fitted RideWrap frame protection
- Fox Float 36 Factory fork with GRIP X2 damper
- Fox Float X Factory rear shock

- Frame-size-specific dropper posts
- Aggressive Maxxis enduro tyres
This isn’t a bike that needs immediate upgrades. It arrives ready for serious trail riding, enduro stages, technical back-country adventures and repeated bike-park laps.

Avinox M2S Power
The Avinox M2S is one of the most exciting drive systems in modern electric mountain biking.
Delivering up to 150Nm of maximum torque and 1,300W of peak power, it provides the strength needed to tackle exceptionally steep gradients and power through demanding technical sections.
The system combines its raw output with responsive software and multiple sensors to deliver assistance smoothly. This helps maintain traction and control instead of producing sudden, difficult-to-manage surges.
Five assistance modes allow the rider to adapt the bike to the terrain:
- Eco for maximising battery efficiency
- Auto for intelligent, responsive assistance
- Trail for natural support across varied terrain
- Turbo for powerful sustained assistance
- Boost for maximum performance when needed
800Wh Battery
The integrated 800Wh battery gives the Karve RSX the capacity for long trail rides, big days in the hills and repeated descents.
Its low, central positioning contributes to balanced weight distribution and keeps the frame looking clean and compact.
The battery is fixed securely inside the frame. It can be removed for servicing or maintenance after the motor has been removed.
Actual range will vary depending on rider weight, terrain, elevation, assistance mode, temperature, tyre choice and riding style.
12A Fast Charger
The RSX includes Avinox’s powerful 12A fast charger, dramatically reducing charging time compared with a conventional e-bike charger.
Approximate charging times from empty are:
- 80% charge: 1 hour 45 minutes
- 100% charge: 2 hours 23 minutes
This makes it easier to add a meaningful amount of battery during a lunch stop or between riding sessions.
Integrated Display and Connectivity
The Avinox DPC100 OLED touchscreen is integrated neatly into the top tube, placing customisable ride and system information within easy view.
A discreet wireless handlebar controller allows assistance modes to be changed without cluttering the cockpit.
The system also connects to the Avinox Ride smartphone app, providing additional system information, ride data and customisation options.
Motor-Powered SRAM AXS Shifting
The SRAM S1000 AXS Eagle derailleur is powered directly by the bike’s main electrical system, removing the need to keep a separate derailleur battery charged.
Avinox SmoothShift technology works with the electronic transmission to help deliver controlled gear changes, even when the motor is providing assistance.
The SRAM AXS rocker pod keeps shifting fast and intuitive, while the 10–52T cassette supplies the wide gear range needed for steep technical climbs and fast trail sections.
Full-Carbon Frame
The Karve RSX uses a uni-directional carbon-fibre mainframe and carbon rear triangle.
This premium construction helps keep the bike’s weight to 22.9kg in size Large while providing the strength and stiffness required for aggressive full-power e-MTB riding.
Internal cable routing maintains the bike’s clean appearance, while the factory-fitted RideWrap protection kit helps defend the finish against trail debris, scuffs and everyday wear.
160mm Quad-Link 4 Suspension
With 160mm of suspension travel at both ends, the Karve RSX is built for aggressive trail riding, enduro terrain, bike-park laps and technical back-country adventures.
Whyte’s Quad-Link 4 suspension system is designed to balance grip, support and control. The custom-tuned Fox rear shock helps the bike remain composed under braking and through rough, repeated impacts.
The system supports confident descending without removing the responsiveness needed for natural singletrack and longer rides.
Fox Factory Suspension
The Fox Float 36 Factory fork delivers 160mm of travel and uses the highly adjustable GRIP X2 damper, custom-tuned for Whyte.
Its 36mm chassis provides precise steering and support for aggressive riding without the bulk of a heavier downhill-focused fork.
At the rear, the Fox Float X Factory shock uses an EVOL LV air spring and a Whyte-specific tune to complement the Quad-Link 4 suspension system.
The Kashima-coated Factory suspension provides premium performance, adjustment and appearance straight out of the box.
Proportional Geometry
The Karve RSX uses proportional sizing across the complete size range.
Rather than fitting the same rear-centre length to every bike, Whyte adjusts key dimensions to help maintain consistent rider weight distribution and handling:
- Small rear centre: 445mm
- Medium rear centre: 445mm
- Large rear centre: 455mm
- Extra Large rear centre: 465mm
The reach, front centre, rear centre and dropper travel are matched to each frame size, helping every rider achieve the balanced and predictable handling the bike was designed to provide.
Adjustable High and Low Geometry
Whyte’s Shape.It Link V2 allows the geometry to be adjusted to suit the terrain and riding style.
Moving into the low setting:
- Slackens the head angle by 0.6°
- Lowers the bottom bracket by 8mm
- Creates a more planted feel on steep terrain
- Adds stability on fast descents and bike-park trails
The high setting provides additional pedal clearance and a more responsive setup for technical climbing, varied trails and longer days in the hills.
Full 29er With MX Compatibility
The Karve RSX is supplied with 29in wheels at the front and rear for maximum rollover capability, momentum and stability through rough terrain.
Riders looking for a more agile, corner-focused character can convert it to an MX setup with a 29in front wheel and 27.5in rear wheel.
Conversion requires:
- Whyte MX-specific Shape.It Link, part WAMLINK07
- Category 4 enduro-rated 27.5in rear wheel
Using the correct components retains the ability to switch between the high and low geometry positions.
DT Swiss Hybrid H1900 Wheels
DT Swiss Hybrid H1900 wheels are specifically designed for the higher loads created by electric mountain bikes.
They provide the strength and dependability needed for aggressive riding while retaining the responsive feel expected from a premium trail wheelset.
The rear wheel uses a strong SRAM XD steel driver, while DT Swiss Elemental spokes complete the e-MTB-specific build.
SRAM Maven Silver Brakes
SRAM Maven Silver four-piston hydraulic brakes provide the stopping power required for a fast, full-power electric mountain bike.
The front brake uses a large 220mm HS2 rotor, while the rear uses a 200mm HS2 rotor. Sintered pads deliver dependable performance on long descents and in wet or muddy conditions.
Maxxis Enduro Tyres
The Karve RSX comes with a proven aggressive tyre combination:
- Front: Maxxis Assegai WT, 29 x 2.5in, 3C MaxxGrip and EXO+ casing
- Rear: Maxxis Minion DHR II WT, 29 x 2.5in, 3C MaxxTerra and DoubleDown casing
The Assegai provides excellent front-end grip and confidence, while the Minion DHR II delivers braking traction and predictable cornering.
Both tyres are tubeless-ready.
