Keiser

I teach at various facilities and there are days when I teach several classes using different bike platforms. However, the Keiser bike remains one of my favorite platforms. Keiser makes the M series and offers three variants:

  1. M3 Series (the classic)
  2. M3+ Series (only difference are the fore and aft adjustable handlebars)
  3. M3i which offers custom color choices as well as Bluetooth/PIQ integration for output metrics

Many new studios and those that heavily invest in technology have installed the M3i. Although more expensive than its predecessors, the M3i is a an upsell for studios where it would justify charging more per rider per class. However, all M series bikes offer an onboard computer which tracks output, cadence, wattage, heart rate, trip distance and KCals. For new riders, the PIQ and wireless integration can be distracting as they are trying to learn the basics of a spin class. I have held on introducing these elements until riders have developed a more sound understanding of ride mechanics, bike setup, posture, comfort and safety. All platforms use a smooth band-operated flywheel which is very quiet.

Observations/Issues:

  1. Most students who want to move the bike end up dragging it which sometimes crushes the rubberized stabilizers (feet) and in the worst of cases, shears them off. The trick is to tilt the bike forward using the handlebars and then use the roller blade wheels to relocate the bike. Unfortunately, even with proper technique, I noticed cleaning staff at some facilities dragging the bikes. That leads to wobbling when you can no longer adjust the stabilizers (you can screw/unscrew them to adjust position).
  2. The seat leather cracks and flakes off in some cases from repeated use and repeated cleaning (with wipes when provided). Again, cleaning crews should not use abrasive chemicals to clean any part of the bike.
  3. The pedals tend to rust during winter classes when riders come in using regular athletic shoes that they wear in snow/salt.
  4. For riders that do not use cleats, the straps tend to fray and break off after prolonged use.
