Bowflex’s C6 and Sole’s SB900 are both top options for spin bikes in the $1000 price range, but they’re quite different when you think about it.

Both bikes score well when it comes to performance specs, but the C6 is designed with a few extra features that make it perfect for pairing with streaming apps, while the SB900 is a little more old school.

Ultimately, when choosing between these 2 elite bikes, it really comes down to what you’re looking for, but it can still be a tough decision.

Don’t fret though, I got your back.

In this review, I’ll compare the Bowflex C6 and the Sole SB900 head-to-head with regards to all the most important specs and features these bikes have to offer.

The Bowflex C6 vs The Sole SB900

I’m gonna be honest- I like Bowflex, but Sole is probably my favorite overall home fitness brand.

I like them so much because their machines are straightforward and they’re designed to last. And I love that they offer some of the best warranties on the market, but more on that in a bit.

Sole also has a pretty large selection of cardio equipment to choose from, with options in the affordable to moderate price ranges.

Bowflex obviously started with their home gyms, but they’ve also become well-known for their cardio equipment too lately.

And Bowflex also scores highly when it comes to the heavydutiness (I’m not sure that’s a real word) and quality of their products.

The C6 is 1 of 2 indoor cycles being offered by Bowflex (the other being the innovative VeloCore), while the SB900 is 1 of 3 being offered by Sole (alongside the SB700 and the more expensive Johhny G).

The C6 and the SB900 are both very popular cycles and they both usually find themselves near the top of bloggers’ “best of” lists each year.

Resistance

I like to start my comparisons off with a rundown on the performance specs and since we’re talking spin bikes here, I think the resistance systems are a great place to start.

One of the great things about a quality spin bike is they are capable of providing a killer workout.

Of course, in order to do this, the bike has got to be able to provide enough resistance to provide a challenging workout.

Most home indoor cycles use weighted flywheels paired with either a friction brake or a magnetic resistance system to do this.

When it comes to weighted flywheels, having a heavier flywheel is beneficial because it builds more momentum as it spins, which reduces lag between pedal strokes.

The result is a smoother feel during workouts.

Heavier flywheels are also capable of providing more overall resistance because it takes more energy to get that flywheel moving.

The C6 comes with a 40 lb flywheel, which is quite impressive for any spin bike, but the SB900 is packing even more heat with a 48 lb flywheel.

At 48 lb, I feel comfortable saying that the SB900 comes with a massive flywheel.

If you’re actively looking for a bike with a heavy flywheel, this alone might be enough reason to opt for the SB900, but the C6 is no slouch in this department either.

The SB900 comes with a heavier flywheel, but it’s fair to say both bikes have very heavy flywheels.

Both bikes also use magnetic resistance systems, which are much more preferred over friction brakes, but there’s a pretty big difference between them.

The C6 comes with 100 levels of resistance (adjusted by turning dial) and you can digitally see what level you’re on with the included console.

On the SB900 you also adjust levels by turning a resistance knob, but unlike the C6, you can’t see which level you’re on.

In other words, there are no distinct “levels” with the SB900.

The SB900 comes with a heavier flywheel, so odds are it’s capable of providing more overall resistance than the C6, but not being able to see which level you’re on could be a disadvantage.

Especially for beginning riders or folks planning on using a streaming app for workouts.

Overall, the SB900 comes with a significantly heavier flywheel, but the C6’s 100 resistance levels is a big advantage when it comes to following fitness apps (like Peloton’s).

Frame

The resistance system is where we probably see the biggest difference between these 2 bikes, but it’s still a good idea to do your due diligence and check out the rest of the bikes.

I always like to get an idea of how stable and secure a bike will feel while riding, which can be difficult without being able to try it out first.

The next best thing though, is to look at the assembled weight because this tells you how heavy (duty) the bike is.

Seeing a heavier bike is a good thing because it’ll be less likely to rock or move during workouts.

With this in mind, the C6 weighs about 112 lb fully assembled, which is pretty solid for a spin bike in this price range.

The SB900 comes with an assembled weight of 160 lb though, which is much heavier.

And the SB900’s flywheel only weighs 8 lb more, so the rest of that weight is coming from the extra bulk of the frame.

Even looking at photos of these 2 bikes, it’s pretty easy to see that the SB900 looks like a much thicker bike.

Which makes it interesting when we compare weight capacities because the C6 comes with a higher 330 lb weight limit compared to the SB900’s 300 lb limit.

I don’t doubt for a second that the SB900 couldn’t hold more weight than that, but that’s what Sole has tested it against, so there we go.

Regardless of what the weight limits are, I still consider the SB900 to be a much heavier duty bike, so if you’re a bigger individual or a home with multiple users, this is certainly something worth considering.

But overall, both cycles score well in the frame department.

Warranty

Regardless of what kind of exercise bike I’m looking at, I always stress the important of checking out the warranty because I think it tells you a lot about the quality of the bike.

As I write this, I know that rule isn’t always true though.

For example, the Peloton Bike is amazing and their warranty actually kinda sucks, so warranty and quality don’t always go hand in hand.

But generally speaking, nicer bikes tend to come with longer warranties.

Anyway, let’s take a look at the residential warranties offered on these 2 cycles. Let’s start with Bowflex’s guarantee on the C6:

• 10 year frame
• 3 year parts/electronics
• 1 year labor

Ok, and here’s Sole’s warranty for their SB900:

• Lifetime frame
• 3 year parts/electronics
• 1 year labor

Ok, so very similar warranties here.

Sole’s lifetime frame guarantee is technically better than Bowflex’s 10 year guarantee, but to be fair- I don’t think anybody’s gonna complain if they “only” get 10 years out their bike.

Maybe I’m wrong.

Either way, it’s unlikely something’s going to go wrong with the frame anyway.

3 years on parts/electronics is generous for both brands and a year on labor is what pretty much everyone offers.

Overall, Sole’s warranty is a bit better, but both come with great guarantees.

(Sole actually offers a light commercial warranty on their SB900 as well- it’s identical to the warranty stated above).

Features

Ok, time to talk features.

This shouldn’t take too long, since both of these bikes are pretty simple when it comes to the consoles, but let’s start with the C6 regardless.

The C6 comes with a small LCD screen that displays basic metrics like speed, distance, time, calories, and cadence.

That little console is also compatible with bluetooth heart rate monitors and Bowflex even includes an arm band with purchase.

As I mentioned earlier, that console also displays what resistance level you’re on.

You also get a free year of JRNY, Bowflex’s streaming fitness app, if you purchase the C6. Through JRNY, you get access to workouts, metric tracking, and virtual scenic rides.

The C6 comes with a tablet holder, so you can easily prop your tablet up there to access JRNY or other fitness apps like Peloton or Zwift.

The 100 level resistance system makes it really easy to use the Peloton app, by the way.

Otherwise, the C6 comes with a fully adjustable seat and handlebars, dual-sided pedals (SPD and toe cage), and a pair of 3 lb dumbbells, as well as dual water bottle holders.

Sole’s SB900 also comes with a small LCD console, but it’s not quite as nice as Bowflex’s.

It also displays time, distances, calories, and cadence, but it doesn’t look quite as attractive as Bowflex’s monitor if you ask me.

It too is compatible with wireless heart rate monitors, but one isn’t included.

Otherwise, the SB900 also comes with a fully adjustable seat, fully adjustable handlebars, and dual compatible pedals.

There’s also a tablet holder and water bottle holder, but that’s about it.

Overall, the C6 definitely comes with more features than the SB900. And if you’re interested in accessing streaming apps, the C6 is the better choice with the included dumbbells and measurable resistance levels.

Price

We’re coming down to the end of this comparison, so it’s probably about time to talk dineros.

At the time of writing this, both bikes come with the same full retail asking price of:

$999

Yup, these bikes come with the same asking price, although as I’m writing this, Amazon has the Sole SB900 on sale for $799, which is as cheap as I’ve ever seen it.

At the same price, it’s hard enough to decide between these 2 cycles, but at that price it’s even harder.

Overall though, I think both bikes are priced fairly, considering everything each has to offer.

Other Considerations

I like to save this little area for any extra tidbits of wisdom I want to throw in before finishing the review.

In this case, I just want to say that Bowflex and Sole both come with great reputations as brands and both of these bikes are very highly reviewed by users.

Both brands come with some complaints regarding customer service, but neither has the awful customer reputation of say NordicTrack or ProForm.

Final Thoughts

Well, that about does it, time to wrap this thing up.

The Bowflex C6 and the Sole SB900 are both elite cycles with a lot of great specs and features.

That said, if I was buying one of these bikes today, I’d go with…

Bowflex’s C6.

Yeah, I hate to go against Sole, but for me I know I would want to be able to see which resistance level I’m on (I’ve been spoiled by my Peloton).

If Sole ever updates their console so that it too displays the resistance level, I’d probably switch and go with the SB900.

But I also like that the C6 comes with a heart rate monitor and a pair of dumbbells too.

If you plan on using the Peloton app or other streaming apps, the C6 is easily the better option.

That said, if you don’t care about streaming apps and just want to do your own thing, then the SB900 is probably the better buy.

In terms of performance, it certainly comes with a heavier flywheel, a heavier-duty frame, and a better warranty.

In other words, the SB900 is more like an old school elite cycle.

Overall, both bikes are awesome and there really isn’t a wrong option here, but when it comes to Bowflex’s C6 vs Sole’s SB900, I’m going with the C6.
