Hands down the best bike around

VERIFIED PURCHASE
I have had the chance to use these bikes for the past several years. Having one available to me in my own house at an affordable price cannot be beat. Prior to purchasing the Keiser M3 we tried a more economical brand off amazon and to keep it brief one of the pedals broke off. Keiser bikes are made for athletes.

Amazing Ride!

VERIFIED PURCHASE
I am absolutely thrilled with my new Keiser M3. I love how study the bike feels. I'm 6' and my husband is 6'1. We both feel super comfortable during our riding sessions. Quiet, smooth ride...and I love that the bike is built in the USA. Custom service was top notch too... Can't wait to enjoy the bike for years to come.

TERRIFIC BIKE

i HAD AN EARLY M3 purchased in 2010. This new bike is a replacement. I notice my watt ratings are lower when compared with the settings from the previous bike.
The old bike was 150 watts at #14, the new bike is 110 at #15

Keiser Responded:

Hi Bob,

Even if your cadence is consistent in those two gears, the wattage of a new cycle and an old cycle can't accurately be compared once the cycles are that far apart in age. We make changes to the software over time to be as accurate as possible, and other minor differences in the cycle design can contribute to the disparity in the readout.

Glad to hear you're enjoying it!

Thank you,

Awesome bike

VERIFIED PURCHASE
Love this bike it is my second one (bike 1 was purchased used and finally gave out). I like that the important features are in the back so they don’t get sweat....and was very easy to put together. This is a heavy duty hard work8n* bike for someone who rides every day for at least 90 minutes.
