Wahoo KICKR Core 2 Electromagnetic Direct Drive Bicycle Trainer (Black)
WFBKTR125
A direct-drive smart trainer for riders who want a dependable indoor setup, available with either a real cassette pre-installed or a Zwift Cog for instant virtual shifting — your choice.
Overview
KICKR Core 2 is Wahoo's update to the trusted CORE platform, built for riders who want reliable direct-drive training without stepping up to the flagship KICKR. This listing lets you choose the drivetrain setup that fits how you'll actually ride: an 11-speed cassette pre-installed for riding with your bike's existing gearing, or a Zwift Cog pre-fitted for instant virtual shifting in Zwift with no cassette to source separately.
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. Hub adapters for both quick-release and thru-axle hubs are included, so most bikes mount without extra hardware.
It's built for riders settling into a regular indoor routine — structured Zwift sessions, ERG workouts, or 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
Choose Your Drivetrain Setup
Pick the 11-Speed Cassette variant if you want to ride with your bike's existing gearing, or the Zwift Cog variant for instant virtual shifting with nothing extra to source.
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. Choose the cassette variant if you want to keep riding your bike's own gearing, or the Zwift Cog variant if virtual shifting and a simpler first setup matter more.
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 variant pairs with a separate Zwift Click shifter (sold separately) to unlock virtual shifting in Zwift.
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.
