First of all, Bowflex makes 3 different models: the TC5, TC10 and TC20 (note that these have replaced the old TC1000, TC3000 and TC5000 models which have been discontinued).
The TC5 is the most affordable model at around $999. However it’s also very basic with no frills. It is non-motorized, which means it works more like a manual treadmill in that you power the belt yourself with your feet.
However it still works like a standard Treadclimber with rising dual belts and can help you burn calories very quickly. The upside of having no motor is that it’s quieter than the other models. Plus you can also place it anywhere in the room – it doesn’t need to be near a plug outlet.
The console is also quite simple, with only one small console window that toggles back and forth showing your calories burned, speed, distance and time. There is no heart rate monitor and you are covered by a 1 year warranty.
The next model up is the TC10 at around $2199. It is the most affordable motorized Treadclimber and gives you a rear step platform that you don’t get with the TC5. This is a great safety feature and makes it easier to get on and off the machine.
The TC10 also comes with 4 different console windows so you can see all your stats at once and don’t have to toggle back and forth. It stores and tracks workout information for 1 user and adds a G.O. coach which shows the weekly progress of 1 user towards a 90 minute goal.
It comes with a 2 year warranty and is the top selling model in the Treadclimber series.
The next model up – the “luxury” treadclimber – is the TC20, coming in around $3299. This motorized Treadclimber gives you longer treadles that other units (great for taller users) and a much larger, backlit console showing all of your information at once.
It comes with 8 built-in workouts and integrated heart rate tracking – something else you don’t get with the other machines.
It also stores and track information for up to 2 different users, which makes it ideal for homes with multiple-users. It also carries the longest warranty – up to 3 years.
So those are the main differences between Treadclimber models. It’s basically up to you, your goals and your budget as to which machine is best for you.
