Bike trainers have evolved over the years…

Ask any long-time rider to recall their first indoor training experience and it probably sounds like a B-grade horror movie; you’d hop on your stationary torture machine and grind away in agony in an aptly-named “pain room.” On your indoor trainer, no one can hear you scream…

But thanks to the ingenuity of some cycling engineers, indoor bike training has advanced considerably in the last few years. It’s a faster, happier, indoor training world full of new acronymic descriptors: AR (augmented resistance), VR (virtual reality), and PM (performance metrics). We’ve built tools to immerse ourselves in virtual cycling utopias (Zwift) and simulate the ascents and descents of downloaded routes. We’ve gotten better at tracking our training data by incorporating pinpoint accurate sensors in nearly every gear and chain. It’s the second coming of the indoor cyclist.

How Do You Choose the Right Trainer?

With so many options, understanding what trainers do and which one is right for you can get overwhelming. In response, here’s our beginner’s guide to answer all of your indoor bike trainer questions when searching for your next indoor trainer.

Types of Bike Trainers

Indoor Bike Trainers are created with a few different types of resistance. Each type has its own particular benefits, and it depends on the needs of the rider.

Fluid Trainers

As the name describes fluid trainers, use a hydraulic substance to modulate resistance. Pedal faster, and the fluid and internal flat blades will increase the resistance.

Something to Consider: While fluid-style trainers are some of the more realistic trainers, some riders have reported overheating or leaking if pushed too hard. Many newer models have gotten better about this issue, but consider this factor if you want a trainer to last you for a long time.

Wind Trainers

In wind bike trainers, your resistance is determined by how hard you pedal the fan from your bike’s back wheel.

Something to Consider: Wind-based trainers are generally a cheaper option, but there’s a lot of drawbacks. They’re noisy, have little resistance customization, and, if you pedal hard enough, you can quickly reach a “peak” resistance. These aren’t recommended for those looking for plenty of options and capabilities.

Magnetic Trainers

These types of machines use opposing magnets to provide resistance. An internal ‘flywheel’ filled with magnets gets closer together, begins to attract, and – through the magic of science – causes greater resistance for the rider.

Something to Consider: The price of magnetic-based machines is dependent on how your trainer adjusts resistance. Certain lower-cost models require the rider to manually change the resistance once you’re off the machine. The more expensive options have a lever that adjusts the resistance.

Roller Trainers

These are the original indoor bike trainers. Many “OG” riders will remember these in their living rooms or garages as they were one of the first indoor trainers for riders. Bikes sit on three rollers which turn as you pedal and create resistance.

Something to Consider:  These rollers are good for building up your form, but the resistance range isn’t close to what you’ll find in other types of trainers. Also, it takes some practice to keep steady so you don’t fall or slide off. If you want a more stable option, consider the other types of trainers.

Flywheel Trainers

Flywheel-based resistance trainers are indoor trainers that, unquestionably, provide the best training experience. They’re the most realistic and they offer almost unlimited resistance options.

Something to Consider: Generally flywheel-type trainers aren’t as portable as other types of trainers, but the features they provide to riders tend to outweigh the cons.

Smart Trainers

These can technically be any combination of the aforementioned resistance types, but they have one important commonality: digital connectivity.

“Smart” trainers are just that – intelligent machines that can connect and communicate with third-party software to provide data feedback and management. This gives your trainer the ability to modulate resistance automatically – like when you go up virtual hills on Zwift, or when want to replicate a route downloaded to your bike computer.

Wahoo’s KICKRKICKR SNAP, and KICKR CORE fit in this category. With all of our smart trainers, you’ll have total connectivity through new apps, software, and attachments including the KICKR CLIMB Grade Simulator and the KICKR HEADWIND Smart Fan. We’ve built our smart trainers to last and fit the specific needs of the rider. Everyone trains differently, so it’s important to have options.

Smart Bikes

Combining the digital connectivity of a smart trainer with the ease-of-use of an exercise bike, smart bikes are emerging as a popular new indoor training option. They work right out of the box and don’t require you to purchase a bike frame in order to ride.

Wahoo’s KICKR BIKE combines the grade simulating of KICKR CLIMB and the near silent-operation of the KICKR and adds several new features that heighten the realism of the ride. Virtual shifting creates a highly realistic experience by giving sensory feedback when users shift. There is a range of shifter set up options that emulate real-world systems including SRAM, Campagnolo, and Shimano. An onboard motor provides a steady slow down when users stop pedaling, making coasting feel more real.

Pick Your Important Factors

There are several important factors to consider when picking out a bike trainer:

Factor: Real-Ride Feel

Do you like to feel like you’re traveling on a real road while you’re training indoors? More advanced bike trainers, like flywheel and fluid trainers, will definitely provide a smoother ride over others. We generally suggest riders choose bike trainers that simulate real conditions and elevations as they translate better when moving workouts from indoors to outdoors or vice versa.

Also, if you plan to output some serious work on your trainer, be prepared to spend a little more on a rig that feels capable of taking hours of abuse. The last thing you want is to end up on the floor with a broken trainer (or tailbone) because you had a sudden second wind.

Factor: Adjustable Resistance

Maybe you just want to cruise on your bike trainer and don’t foresee lots of resistance changes during your workouts. Maybe you love working hills and need quick resistance adjustments. Whatever your angle, it’s important to consider that adjusting the resistance on certain types of trainers can take up lots of your time during workout sessions. Choose the trainer that best fits how you train.

Factor: Noise

Wind trainers are noisy. If you’re living in an apartment, or in close quarters with a roommate, new baby, or sound-sensitive individual, these may not be for you.

Noise can also be annoying to you; indoor workouts can potentially last a while, so be certain you’re okay with some noise before buying your new trainer.

The new KICKR Smart Trainer is the quietest trainer we have ever produced. Live in an apartment, condo or have a little one napping? We have you covered, the only sound you will hear is your muscles screaming for you to stop.

Factor: Adaptability

Nowadays, we connect our smartphones to everything – our cars, our bank accounts, even our coffee baristas. It’s also where we keep our workout plans. Pairing your smartphone to your indoor bike trainer is a feature only available to smart trainers like the KICKR. It’s an important consideration for choosing the right indoor trainer.

For those using TrainerRoad or Planned Workouts, the KICKR pairs directly with your ELEMNT. Your KICKR’s resistance will adjust according to your recreated route in real-time. TrainerRoad and Planned Workouts are ideal for training and following a workout plan. This kind of integration is seamless and provides tons of value.

Factor: Pairing Sensors

You may also want to pair your sensors up to your bike trainer. As you know, tracking and recording performance metrics is important to the long-term success of any athlete. Whether it’s your speed, cadence, the CLIMB or the HEADWIND Smart Fan, you’ll want to have plenty of ways to track your progress as you train.

Factor: Experience

As we painfully admit, riding indoors for long periods of time can get monotonous. That’s why many riders have turned to smart trainers like the KICKR for the ability to incorporate the excitement of Zwift and other apps into their training. It’s not always easy (or possible) to connect and ride with friends in the real world, so having an online social community to ride alongside is a welcome option. And, for many, the social capabilities of the smart trainer is their sole motivation to continue to train indoors. Make sure that your trainer is fun to use as you’ll probably be on it a lot!

Factor: Ease of Use

Some people want to immediately hop on a bike and ride. They may have more than one rider in the house for one piece of equipment. 

For users who prioritize ease of use, the KICKR BIKE the solution. It takes only ten minutes to assemble the first time and then there is no additional set up required for the rest of its lifespan. It has five quick-release adjustment points that can be changed to fit riders of any size, allowing new users to walk up to it and start cycling in seconds.

Factor: Budget

The all-important factor: money. While it’s easy to let this single factor drive your entire decision-making process, remember that you’re making an investment in a piece of important tech that you want to last. It’ll add up considerably if you’re going through trainers every couple of months or years. Also, cheaper options are sometimes only compatible with a select type of bikes; If you’re planning on upgrading soon, make sure that the trainer can fit your new ride.

At Wahoo, we offer a few versions of our smart trainer the KICKR. If you’re not ready for the newest KICKR, the KICKR CORE and the KICKR SNAP is a welcome and are no-less-capable smart trainers. If cost is not an issue and you want all the latest tech, consider the KICKR BIKE. Like all Wahoo products, these trainers have effortless integration into your training ecosystem.

Find Your Fit

In the end, the choice is yours. So many factors play into choosing a bike trainer, and it’s your decision to decide what works best for you and your training style. We take the aforementioned questions into careful consideration when designing our trainers.  Our goals are to make a product that fits all the needs of the modern cyclist. The KICKR, for example, is what we believe to be the most advanced, flexible, and complete bike trainer on the market. And with the innovative modulations, we’re always building to accompany it (like the KICKR CLIMB), we’re always upgrading your bike trainer to the latest in bike tech.
