I don't have any experience with the Trixter bikes, but I too, am finding myself in the position of adapting to a new and different type of spin bike than what I'm used to. The gym I normally take spin classes at (a former Bally's which has been taken over by LA Fitness), use the Star Trac Spinner bike...which is very similar (if not identical to the original Schwinn Spinner bikes). But another LA Fitness near me which is a much newer facility, uses the Keiser M3 spin bikes...VERY different than the original spin bikes. The resistance knob is way different, the handlerbar & saddle adjustments are way different, too. I'm not sure if I've "warmed up" to this newer type of spin bike just yet. I'll have to do a few more classes on it, before deciding if I like it.
