Wahoo KICKR Core 2 Electromagnetic Direct Drive Bicycle Trainer w/ Zwift Cog/Click (Black)
WFBKTR125-3CC
A direct-drive smart trainer for riders who want a genuinely reliable Zwift setup, with a pre-fitted cog that skips the cassette entirely and gets you shifting virtually from the first ride.
Overview
KICKR Core 2 is Wahoo's update to the trusted CORE platform, aimed at riders who want dependable direct-drive training without stepping up to the flagship KICKR. The core idea hasn't changed — remove the rear wheel, mount the bike directly, and eliminate the tyre wear and slippage that come with wheel-on trainers — but the second generation adds the connectivity Wahoo's higher-end trainers already had.
What's actually equipped: integrated WiFi handles automatic firmware updates and enables KICKR Bridge, which relays a paired heart-rate sensor's data through the trainer rather than needing its own Bluetooth slot on your device. Race Mode pushes power data out at a much faster rate for quick-response virtual racing. This version comes with a Zwift Cog and Click shifter pre-fitted, so there's no cassette to buy or swap — you're riding and shifting virtually as soon as it's mounted.
It's built for riders settling into a regular indoor routine — structured Zwift sessions, ERG workouts, or just consistent training through the months when outdoor riding time is limited — who want a trainer that stays out of the way once it's set up.
Why You'll Like It
No Cassette to Buy or Fit
The Zwift Cog and Click shifter come pre-installed, so you're riding and virtually shifting in Zwift straight out of the box — no separate cassette purchase or drivetrain matching required.
WiFi Keeps the Connection Solid
Integrated WiFi handles firmware updates automatically and enables KICKR Bridge, which streams a paired heart-rate sensor's data through the trainer instead of competing for a Bluetooth slot on your phone or head unit.
Built for Fast-Paced Racing
Race Mode transmits power data at a much higher rate than standard Bluetooth power broadcasts, which matters when following pack dynamics in a Zwift race.
Simpler Setup Than the Original CORE
A redesigned four-bolt leg assembly with colour-coded parts is built to go together faster and lock in more securely than the original CORE's fold-out legs.
Wide Bike Compatibility
Hub adapters for both 130/135mm quick-release and 142/148mm thru-axle hubs are included, so most road, gravel, and mountain bikes mount without extra parts.
Who Is It For?
Riders in India who want a dependable, low-fuss entry into direct-drive training — especially anyone building a regular Zwift habit through the hotter months when outdoor riding drops off. The pre-fitted Zwift Cog removes a common first-trainer friction point: matching a cassette to your bike before you can even start riding.
It also suits a household or shared setup where more than one bike needs to go on the trainer — the quick-release and thru-axle adapters mean swapping between road and mountain bikes doesn't require extra hardware.
Good to Know
The Zwift Cog and Click shifter connect over Bluetooth, so keep that in mind when planning your device connections during a ride.
KICKR Bridge is worth setting up early — pairing your heart-rate sensor to the trainer once means you won't need to manage that connection separately in every app afterward.
WiFi setup through the Wahoo app takes just a few minutes and keeps the trainer's firmware current automatically from then on.
