Our Rating
Rating: 86.75/100. The Keiser M Series is the world’s most widely used fleet of indoor bikes. Each model is commercial quality and sold with a choice of warranties for home or professional use. Of the three spin bike choices in this high-end collection, the portable Keiser M3 is the lowest priced at $1,795 including delivery. It supports the same quality of exercise as the pricier M3i and M3iX, but without their Bluetooth data logging or the latter’s offroad-style handlebars. All three Keiser bikes feature the same impressive drive: a quiet magnetic flywheel system with 24 levels of resistance. It ensures smooth pedaling that feels like real road biking, and the resistance range suits all ability levels.
Other basics of the Keiser M3 include multi-position handlebars; industrial-grade pedals with integrated cages; and a data monitor. With its four-way adjustable saddle and a high weight capacity, the Keiser M3 bike fits just about any shopper too.
Overall the M3 is a favorite choice for exercising with spin bike instruction, and instructors at top gyms have Keiser certifications. The main potential drawback is that unlike some competitors, the M3 lacks built-in training programs or a connection to live studio instruction. Lists of pros and cons are below.
Pros:
- Feels like a road bike
- Quiet magnetic resistance
- 24 resistance levels
- Adjustable saddle
- Adjustable handlebars
- Lightweight pedals with cages
- Data monitor
- Compatible with Polar wireless monitors
- No cord required; console uses batteries
- Compact and portable
- Sold in custom colors for paint & upholstery
- Fair warranty; three years on parts
Cons:
- No workout programming included
- No special amenities such as speakers or wireless data logging
- Above-average price for a home exercise bike
Introduction
The Keiser M3 Indoor Bike is a top-choice spin bike for membership gyms and is reviewed here for home use. Below are details about Keiser M3 features and buyer protections.
Keiser M Series Bike Workout Programs
Workouts aren’t built into Keiser spin bikes. The M Series bikes are especially popular with people who enjoy group exercise at gyms, or who ride self-directed.
The top-scoring alternative to this series is the Peloton bike, which connects with live and on demand spin classes. Two-way audio and video are included for a participatory experience. The Peloton is also cheaper than the Keiser M3i at $1,495.
With the Keiser M3 a data monitor shows gear (1 to 24), cadence, distance, time spent cycling, RPM, heart rate and Watts. The data monitor detects ambient light and automatically adds backlighting when needed, so it’s always easy to see your progress and output.
Keiser M3 Features
The M3 is built from durable stainless steel hardware. Even so, the entire unit weighs just 87 pounds. It’s designed to be transported more easily than indoor bikes of comparable quality.
An excellent eddy current resistance system helps make Keiser bikes high-end. Although the flywheel is lightweight, it’s well-designed to make the most of inertia. The result is effective cross training for any skill level and any intensity of bike workout. You can choose from 24 resistance levels.
Keiser pedals are well-engineered to be lightweight, comfortable and durable. With smart ergonomics they minimize pressure on your feet. Cages are integrated for stability.
The saddle adjusts vertically and horizontally to fit almost any adult.
M3 handlebars are adjustable to accommodate different riding postures.
Warranty & Guarantee
For home use in the USA, the Keiser M3 indoor bike warranty includes:
– Frame: 10 years
– All Inclusive (excl. labor and wearable parts): 3 years
– Wearable Parts: 90 days
This model can be returned for a refund, but only if unused. Returns are accepted within 30 days of receipt.
Conclusion
The Keiser M3 is an easy choice for group training. It’s lightweight for its quality and has transport wheels. This model is a favorite for club use, and being commercial quality it can serve trouble-free for many years as a home exercise bike. We also like how the frame color and upholstery can be customized to match anyone’s decor.
For awhile the M3 (if not the M3i) was “the” obvious buy for serious spinners to use at home. In the past several years though, the Peloton bike has become a formidable competitor! If you’d prefer a ride with on-board instruction anytime, and with a sense of immersion in real studio classes, then the pricier Peloton is our top recommendation. Otherwise the Keiser M3 and M3i remain top choices for shoppers with above-average spin bike budgets.
