Keiser M3 Indoor Cycle Review

The Keiser M3 Indoor Cycle ranks among the best indoor cycles on the market, delivering a real-bike feel that even outdoor cycling enthusiasts rave about. Although this model is priced on the high side of the market, it has all the features and durability you would expect in a top-quality exercise machine.

The Good

Sturdy, maintenance-free design

The Keiser M3 Indoor Cycle gets a lot of praise from riders for its build quality and its overall stability on the ground. The cycle is rated for riders up to 300 pounds in weight and provides a rock-solid base even during the most strenuous workouts. What’s more, Keiser has built this cycle from the ground up to combine strength and simplicity in design, creating a machine with virtually no maintenance requirements beyond regular wipe-downs after workouts. An added bonus arising from the simple design is the relatively straightforward assembly process, which most buyers are able to complete in no more than an hour or two.

Attractive warranty terms

The Keiser M3 Indoor Cycle comes with a 10-year warranty on the frame and a three-year warranty on mechanical parts, electronics, and the magnetic braking system. While the 10-year frame warranty matches many competing bikes, the three-year warranty exceeds the terms offered by most other indoor cycles on the market. Although the Keiser M3 Indoor Cycle doesn’t offer any warranty coverage for labor, the cycle is designed such that owners should be able to replace any warrantied parts without need for a service technician or repairperson, thus avoiding labor charges altogether.

Workout monitor includes resistance level and cadence

The Keiser M3 Indoor Cycle is equipped with a simple yet capable cycling computer that monitors and displays both cadence and resistance level right on the screen, in addition to basic stats like time, distance, and calories burned. While most indoor spinning bikes have a cycling computer, few track both cadence and resistance level. Cadence, which is a measure of pedal rotations per minute, is a useful statistic for many types of workouts, especially those focused on developing leg speed, a key performance factor for competitive cyclists. The on-screen resistance level indicator is another very helpful capability that allows you to manually dial in a particular resistance level with accuracy and speed. Other indoor cycles with a manual tension knob, such as the Horizon Fitness M4 Indoor Cycle, provide virtually no indication of the current resistance level, requiring you to rely on little more than guesswork to find the optimum resistance for your planned workout routine.

Helpful shipping options

Like virtually all exercise bike manufacturers, Keiser offers standard delivery service to your door using major shipping providers such as FedEx and UPS. However, Keiser is one of the few manufacturers to also offer in-home delivery options. The LTL shipping service delivers your Keiser M3 Indoor Cycle inside your home, while the LTL Plus service delivers your cycle to a room of your choice, de-crates the equipment, and removes all packaging debris. Keiser doesn’t offer an in-home assembly option, but the bike rates among the easier indoor cycles to assemble given its straightforward design.

The Bad

Relatively high price

While the Keiser M3 Indoor Cycle ranks as one of the very best models in the category, it comes with a pretty big price tag. At a suggested retail price of nearly $1,700, this model costs much more than most traditional upright and recumbent bikes on the market. While the price is not terribly high when compared to other top-shelf indoor cycling models, there are plenty of good options on the market at lower price points. All that said, if you’re looking for a high-quality, durable spinning bike that delivers many hundreds of miles of spinning over many years, this cycle is well worth a close look.

Non-adjustable handlebars

One of the few criticisms this model has come under arises from the handlebar design. Although the handlebars are adjustable in height, they do not adjust forward or back. Given the length of the bike frame, this means that shorter riders may find that they have to lock out their elbows in order to reach and grip the handlebars as intended. While most riders won’t have any trouble using the handlebars comfortably, shorter riders may want to visit a local showroom to test out the bike fit before making a purchase. Do note that Keiser has effectively solved this problem by introducing a new bike model, the M3 Plus Indoor Cycle, which in most respects is just like the M3 except for a new adjustable handlebar system.
