The rear bar integrates a handle which facilitates the tilting of the bike on its front wheels. The assembled bike is not excessively heavy. Considering that it weighs only 91.9 lbs (41.7 kg), almost anyone able to lift 40-45 lbs (18-20 kg) should be able to move it without difficulty.

Seat and handlebars

Needless to say, the main comfort factor of this bike, just as for any other recumbent cycle model, is the seat.

They also features standard threads, which makes it easy to find replacement for them in case they break or in case you want a different type of pedals.

The 9 Heart Rate programs require you to use the EKG sensors built in the machine’s recumbent handlebars. However, the console is also telemetry enabled, so it can track pulse via a HR chest strap that operates within a 4.5-5.5 kHz range. A HR strap is not supplied with the machine, but it can work with a Polar Electro, or an uncoded POLAR model.
