Quick Answer: No, a stock Peloton is not a smart trainer. It has the hardware of one — an accurate power measurement and, on the Bike+, a motor that can change resistance — but it doesn't expose either to outside apps. It won't broadcast power or cadence over Bluetooth or ANT+, and it doesn't support FTMS, the standard training apps use to control trainers. With a hardware bridge, a Bike+ behaves like a full smart trainer including ERG mode.

What makes a trainer "smart"
A smart trainer does two things a dumb trainer can't:
- Broadcasts your data — power in watts and cadence, over Bluetooth or ANT+, so an app can read it
- Accepts resistance commands — an app can tell it "hold 250 watts" or "simulate a 6% gradient" and it complies
The second is what makes ERG mode and gradient simulation possible, and it's delivered through a Bluetooth standard called FTMS (Fitness Machine Service).
Where a Peloton stands
Measured against that definition, a Peloton has the hardware and withholds the interface.
On measurement: the Bike and Bike+ both measure power reasonably accurately — it's how Output is calculated, and we covered the method in how Peloton calculates power. But that figure only ever appears on Peloton's own screen. The bike is not a Bluetooth or ANT+ power sensor. Pair-search from a Garmin or Zwift and nothing appears.
On control: the Bike+ has a motorised resistance system — that's what powers auto-follow during classes. The motor is physically capable of everything ERG mode requires. It just isn't exposed to third-party software. The original Bike has no motor at all; resistance is a manual knob, so no software of any kind can change it.
So the honest answer differs by model:
| Broadcasts power | Can be controlled | Smart trainer? | |
|---|---|---|---|
| Peloton Bike (stock) | No | No motor | No |
| Peloton Bike+ (stock) | No | Motor present, not exposed | No |
| Peloton Bike+ (bridged) | Yes | Yes | Effectively yes |
| Peloton Bike (bridged + SmartSpin2K) | Yes | Yes | Effectively yes |

There's no published reason, but the commercial logic is obvious enough: a Peloton that works as a smart trainer is a Peloton you can use with Zwift instead of paying for a membership. Keeping the data closed keeps the subscription attached.
It isn't a technical limitation. The sensors and the motor are already there.
What "bridging" actually involves
Making a Peloton behave like a smart trainer requires hardware sitting between the bike and the app, because the missing capability is at the hardware interface layer — no app installed on the Peloton screen can reach the sensor bus or the motor.
Once bridged you get:
- Power and cadence broadcast over Bluetooth and ANT+, so Zwift, Rouvy, TrainerRoad, Garmin and Apple Watch can all see the bike
- ERG mode on the Bike+ — resistance holds your target watts automatically
- SIM mode — resistance tracks the gradient of the virtual course
On the original Bike, the broadcast half works the same way; the resistance half needs SmartSpin2K, which physically turns the resistance knob.
Is a Peloton a good smart trainer once bridged?
Better than most people expect. The flywheel is heavy and the ride feel is good — genuinely comparable to dedicated trainers costing several hundred pounds. The power measurement is consistent, which matters more for training than absolute accuracy.
The main caveat is that Peloton's power figure is derived from cadence and resistance rather than measured by a true strain-gauge power meter, so absolute watts may differ from a dedicated power meter by a few percent. For training against yourself over time, consistency is what counts and it's consistent.
How FitSwitch fits in
FitSwitch is a hardware device that plugs into the Peloton's USB port and does exactly this bridging. It reads cadence and resistance directly from the bike, broadcasts them as a standard cycling power and cadence sensor over both Bluetooth and ANT+, and on the Bike+ drives the resistance motor for ERG and SIM mode.
It also puts 55+ apps on the Peloton screen — streaming and training — with no computer, no developer mode and no sideloading, and keeps them updated so a Peloton OS update doesn't wipe your setup.
Frequently Asked Questions
Is a Peloton Bike+ a smart trainer?
Not out of the box. It has the motor and the power measurement a smart trainer needs, but it doesn't broadcast data or accept resistance commands from third-party apps. With a hardware bridge it behaves like one.
Does Peloton support FTMS?
No. Peloton doesn't implement the FTMS Bluetooth standard, which is why training apps can't discover or control the bike directly.
Can Zwift control my Peloton's resistance?
Not on a stock bike. On a bridged Bike+, yes — ERG and SIM mode both work, so Zwift adjusts resistance for gradients and workout targets.
Does the Peloton broadcast power over Bluetooth?
No. A stock Peloton shows power only on its own screen and doesn't advertise itself as a Bluetooth or ANT+ power sensor, so nothing else can read it.
Is Peloton's power accurate?
It's derived from cadence and resistance using a factory power curve rather than measured by a strain gauge, so absolute watts can differ a few percent from a dedicated power meter. It's consistent, which is what matters for training.
Can the original Peloton Bike do ERG mode?
Not by itself — it has no motor, so nothing can change its resistance electronically. Adding SmartSpin2K, which physically turns the resistance knob, enables ERG on the original Bike.
