The M3i is the culmination of more than a decade of improving the M3 model and hundreds of enhancements, including improved sweat drainage around the bike, increased corrosion resistance, and the use of a precision power meter — the first of its kind to pass the European EN957-10 standard for accuracy and safety. But we didn’t stop there. It wasn’t enough for us to have just one bike pass the test; we implemented a quality control and testing program to ensure that every bike we produce passes as well. The M3i continues to raise the bar with integrated Keiser technologies that allow data to be transmitted to multiple Bluetooth® devices simultaneously; your training data can be sent to your mobile phone or tablet while also feeding information to classroom projectors and any other Bluetooth® devices you choose to use. With the legacy of the M3 and more than 300,000 M3 and M3i bikes sold worldwide, this is the most tested and reliable bike on the market. But don’t just take our word for it. Ask our customers.
