Perfect!

VERIFIED PURCHASE
Finally made the decision to purchase my own after being a gym rat for YEARS! Best decision ever. Its a joy to work out on demand. The assembly wasn't too bad, it helps my husband us mechanically inclined. This is a premiere bike and I encourage everyone on the fence or unsure about purchasing to go for it!

My new M3I is better than I could have ever imagined! I live n a remote area n The Rocky Mountains of West Yellowstone,MT. Our weather gets pretty harsh sometimes & limits outdoor activities. My place backs up to a forest & the view I have on my spin bike has me wishing I could stay on it all day! Snow covered mountain tops makes for great spinning with all kinds of wildlife sightings @ any given time!

This spin bike gives me a great workout that I truly enjoy. It's a smooth ride and so quiet. I love that Keiser threw in the media tray (holds my Kindle perfectly) and the sweat mat (protects my braided rug). And, the computer is helpful so I know how hard I'm working and to keep track of time for sprints and so I know how long I've been on the bike. My only complaint is that the computer won't read my Garmin HR monitor. My workouts, if I use my Garmin HR monitor go seamlessly from my device to Garmin Connect to go365. I know if I use the polar HRM I could upload the files to Garmin but it's a hassle to do that so I'll keep using the Garmin HRM so things upload automatically. But, other than the computer not reading the Garmin HRM, I think my new...

Smooth and easily adjustable

VERIFIED PURCHASE
I had used these at a couple of rec centers and knew what I wanted because it adjusts to my size (5’3”, short legs) and I love how the resistance lever is right where I can reach it. Good computer. Also, the most smooth and quiet of the bikes I have used. I go between 10-20 miles per day and the seat hasn’t made me sore either! Love my Keiser❣️

Perfect bike

VERIFIED PURCHASE
Easy to assemble. Did it alone in 45 minutes. Two issues:
1-The instructions say to use the lubricant on the "bottom bracket", but I don't see exactly where to spray the stuff in the video or elsewhere. Plus, I thought bottom bracket bearings were sealed, so they wouldn't need external lubrication.
2-I was EXTREMELY careful while installing the flywheel to avoid scratching it between the magnets. Guess what? I still got a 2-inch scratch on the flywheel, and I suppose I'll never be able to buff that off, remove that scratch, etc. There ought to be a removable soft plastic protector that prevents scratches during flywheel installation. Would be as simple as thick tape, etc. I don't know of a way I could have installed it any gentler or more carefully.

Keiser responded:

Hey Mike,

Very common questions, thanks for bringing it up.

  1. The picture I've included shows where the LPS is typically applied, and though you're correct and the bearing is sealed, it's nonetheless exposed metal that would benefit from additional corrosion protection.
  2. I'm sorry about that, we ship the flywheel in a soft foam sleeve to provide some protection but it can be a little tricky to slide the flywheel in. I will pass your comments to our design and manufacture guys, feedback like this is essential.

Thank you!
