It seems that with the 910ic you can do more workouts of high intensity compared to what’s possible on 510ic. This could also be possible because the 910ic has the capacity to handle 25 pounds more in weight than the 510ic.

The major difference between the two is that 910ic bike has a flywheel 8-pounds heavier than that os the 510ic bike.


Both these bikes have magnetic resistance and they differ in how it is powered. The 510ic uses computer-controlled mechanisms to run and adjustment the bike’s resistance. On the other hand, 910ic uses self-generated electronic power to manage and run the 40-pound flywheel.

This is to say that the 510ic bike needs to be electronically powered to an external power source in order to run. The 910ic bike needs no added power but that generated by the rider because it has heavy-duty pedal cranks that create enough energy to power the motor.

While all this is positive as far as energy saving goes, it is also a huge drawback in terms of the training metrics generated per training session. This is because once you stop pedaling, the bike’s screen goes off and the data is automatically lost.

Levels of resistance on either bike differs by 16 levels. 910ic bike offers double the levels of magnetic resistance at 32 while 510ic goes up to 16 levels. This goes to emphasis the type of heavy training that is possible on the 910ic bike compared to the 510ic.

The 910ic bike uses wireless connection and a compatible paired heart rate monitor to be able to read and display that information.

The 910ic bike, because it features a heavy 40-poud flywheel, it is fitted with a mechanism for double intensity adjustment capability which magnifies and fine-tunes resistance to cater to the higher intensity type of workouts done by pros.
