Get the Revmaster bikes. Then you can get the Pilot machines that attach to the bike, and that measures cadence, speed (kph or mph), calories burned, heart rate, plus has a timer and stopwatch. Plus, they have proactive customer service- they were constantly calling just to check in with the bikes.
Unfortunately, with all bikes, you're eventually going to get that problem with the brakes. The answer to that is PREVENTATIVE MAINTENANCE. If you check the bikes out at least once a week, you should be able to calibrate the brakes yourself. Ideally, you want to check once a day, but if you can't do that, once a week is best. If you write an article about this, the best kind of article you can write is how active, vigilent preventative maintenance can make the bikes last a long time. Our gym runs at least five classes a day with heavy wear, and we've had the bikes now for at least four years, and the reason why we're still happy is that we do PREVENTATIVE MAINTENANCE. A little bit goes a long way and saves you thousands of dollars over the long run- yet clubs continue to do the minumum, but expect the maximum. That is really puzzling.
