Saris M2 Smart Indoor Electromagnetic Resistance Bike Trainer - Zwift

In this review of the Saris M2 Smart Indoor Electromagnetic Resistance Bike Trainer, the bottom line is simple: it is a solid choice for cyclists who want a dependable, app-ready way to train at home. The trainer is aimed at riders who want a direct, wheel-on solution that connects to Zwift and other apps without removing their rear wheel. The single biggest reason to buy is its reliable Bluetooth connectivity and consistent electromagnetic resistance that delivers repeatable workouts session after session.

Key Features

• Wheel-on design: Connects to the rear wheel of a bike so there is no need to remove the wheel or disassemble the frame, making setup quicker for most riders.
• Electromagnetic resistance: Provides a controlled and consistent resistance curve so workouts feel measured and repeatable across rides.
• Connectivity: Dual ANT+ FE-C and Bluetooth standards let the trainer pair with Zwift and other indoor cycling apps for structured and interactive sessions.
• Clutch knob: The innovative clutch knob ensures a secure tire-to-roller contact each ride, reducing slippage and inconsistency during hard efforts.
• Included app access: A one month subscription to the Rouvy virtual training app is included, which helps new users get started with structured routes and training plans.
• Compatibility: Comes with a steel quick release skewer so common road and mountain bike frames can mount without additional hardware.

Who It's For

The Saris M2 suits riders who want a stable, straightforward indoor trainer that works with Zwift and other apps without fuss. It is particularly good for commuters, winter trainers, and cyclists seeking a dependable bike-on trainer that keeps the bike in a familiar setup while delivering consistent resistance.

It may be less appealing for riders who demand near silent operation during intense intervals or those who prefer direct-drive trainers that remove the wheel for the most precise power delivery. If you need ultra-quiet operation below the trainer's typical 69 dB at 20 mph or the tightest possible power precision, consider alternatives.
