Solid, simple, beautiful

VERIFIED PURCHASE
After much dithering over which stationary bike my still-suffering-the-pandemic body needed, I went with what seemed the most straightforward and true -- the bike I'd used in gym spin classes pre-pandemic. I was hesitant at first about the price, but the reviews of its reliability made the Keiser seem right. After all, I'd be the one to now fix it if anything went wrong. I was hesitant about putting the bike together myself, as I don't know one wrench from another, but the task taught me all I had to know about the bike: how it worked overall, how the parts worked together, what I'd need to take apart if a pedal went wonky. It was actually fun to do. And the bike's construction -- it is strong and beautiful. AND made in Fresno! AND I'm actually riding it, enjoying it, and glad I paid the top $$ to get...

Great bike.

VERIFIED PURCHASE
This bike is beautiful, well built. Super easy to use and remember seat and handle bar settings. Easy to assemble but I wish I didn't have to spend so much $$$ on tools to assemble. I have a well stocked toolbox and still found myself at the hardware store buying tools.

Keiser responded:

Hey Joe, we hear you on that. I can highly recommend our M Series Assembly and Maintenance kit, it's actually just $50 when ordered with any new product and is a cost effective way to get what you need.

Thanks for the feedback!

Closest Thing To An Actual Road Bike

There are two types of bikes at my club, Keiser M3 and one made by a company that was once based in Chicago. I ride the M3 all the time. It is the closest thing you will find to an actual road bike. A lot of indoor bikes have a bottom bracket that is way too wide and it alters your stroke and cadence. The M3 feels like you could affix a fork and front wheel and hit the streets. In the market to buy one for the home and I am happy to see the positive reviews on the site from people who feel similarly.

So far—perfect!

VERIFIED PURCHASE
The bike arrived right on time. It was packaged very well and was pretty easy to put together, took about an hour. I've ridden it 10 times and it's been great! Super quiet and solid. Tension control works well and the readout has everything I need—duration, watts, and heart rate (synchs up instantly with my Polar hear rate monitor). I got this bike because I rode one for years at my local fitness center. It's commercial quality in every way.
