Great indoor spin bike

VERIFIED PURCHASE
I'm very happy with my new Keiser M3i. It was delivered fast and was easy to unbox and assemble. I recommend getting the toolkit - having the right tools for the job made assembly a lot easier. The bike is very solid and quiet. I used to ride at a gym, and the Keiser M3i is as good or better than the professional spin bike at the gym.

I received the order ahead of schedule to the East coast. The double box was in excellent shape. The bike was packaged with bubble and shrink wrap and mounted on a wooden base. It was in perfect condition, very impressive. The bike went together easily providing you have a free speciality tools like torque wrench and two sizes of crows feet. I have owned many exercise bikes(sole, echelon) and four road bikes. The M3i is the smoothest and most realistic feel to my road bikes. The handlebar and seat adjustments make it possible to get the bike adjusted perfectly for me. The bike came with many bonus items to include a polar chest heart rate monitor.
