During the development of the anaerobic ergometer the focus was to create a safe bike that is easy to use, combined with an attractive design. The result is Monark Ergomedic 894 E Peak Bike. A new bike however, still with the traditional characteristics of a Monark bike. A brand new frame with a softer design, but with improved performance regarding stability and rigidity. The Windows based software, with more setting possibilities and a clear presentation graphic, is easy to use. Thanks to double sensors, faster electronics and improved mechanics we minimize the possibility for problems during the work with anaerobic tests. The Peak Bike also works as a regular weight ergometer. The weight basket is a patented self-regulating braking system wich don't need calibration. As long as the basket is in the air and the weights are correct even the brakeforce is correct. The mechanics of the weightbasket has been improved wich will increase the safety of the releasing moment. The new Wind
