Why are exercise bikes a good option for people with ‘bad knees’? I remember the pain like it was yesterday. I was 12 years old and playing ‘wall ball’ with my friends. When I turned to dash to the wall, I felt the excruciating stabs as my knee scraped out of joint and I hit the pavement.
It wasn’t until years later that I learned I had torn my lateral collateral ligament (LCL) in my knee. To this day, I do not have an LCL in my left knee. Thanks to some hard training, countless hours of riding exercise bikes, and my physiotherapists, I was able to play football. I also received my black belt in Tae Kwan Do, and was even able to walk 2,600 miles from Canada to Mexico.
Exercise bikes may be a great way to rehab knees. Exercise bikes could also be great for helping to keep one’s knees strong, mobile, and limber. In the Scandinavian Journal of Rehabilitation Medicine, Dr. Mats Ericson, Ph. D. explains that cycling is a useful “exercise in the rehabilitation of patients with injuries to the knee.”
Dr. Ericson also mentions that exercise bikes might be especially useful for those with injuries to the “anterior cruciate ligament” [ACL and] “medial collateral ligament” (MCL).
Exercise bikes also tend to be great for people who are:
- Seeking a low-impact way to get a work out in without unnecessary joint pain
- Looking for a gentle way to improve the strength and mobility of their legs and knees
- Following their doctors advice to use an exercise bike daily
- Ready to rehabilitate after an injury or surgery
- Wanting to read or watch TV while working out their legs and knees
- Seeking an alternative to running without the knee pain
- Needing a safer alternative to riding a bike outside
- Wanting to lose weight in the comfort of their home
- Intimidated by or unable to go the gym
- Looking to improve their health and fitness
- Looking to strengthen or tone their legs or glutes
- Excited to enjoy a variety of workouts with one piece of equipment at home
- Otherwise limited in movement
What is the best type of exercise bike to rehab knee?

When looking for an exercise bike, the main options are recumbent, semi-recumbent, and upright. Some exercise bikes are adjustable and can be used in the recumbent, semi-recumbent, or upright positions. Researchers saw no significant difference between the level of activation of muscle groups between recumbent and upright exercise bikes.
Pros of recumbent exercise bikes:
- Researchers have found that recumbent bikes are useful for patients in their early stages of recovery.
- Recumbent exercise bikes are especially helpful for people looking to improve their ability to step up, sit, or stand.
- Good for people with lower back problems
- A nice option for people who don’t like sitting on regular bicycle seats
- Can help your back stay in a more relaxed position
- Many people find them more comfortable to sit on for longer periods
- Often easier to get on and off than upright bikes. This is often helpful for those with limited movement.
- Can be great for people who struggle with balance or weak legs.
- People are often advised to use recumbent bikes to rehabilitate after a stroke or injury.
- Recumbent exercise bikes may cause less stress on knee joints.
- Sitting in a less upright, position puts less weight on the knee joints
If you are looking for a recumbent exercise bike I review some here
Pros of upright exercise bikes
- They tend to take up less space than recumbent bikes
- More like riding a road or mountain bike
- People training for races or longer rides may find their buttocks will get more used to bike seats
- Researchers found “the rectus femoris muscle demonstrated greater activity during upright pedaling” when compared to recumbent pedaling.
Exercise bike tips for people with ‘bad knees’
Let’s say your doctor suggests you start riding an exercise bike as a way to improve your knees
What might get in your way of committing to this daily exercise routine?If you’re anything like me – it’s finding a way to make riding your exercise bike an activity that will actually commit to. But how do you do that?
How does one start and stick to a new habit such as riding an exercise bike to improve your knees?
- What if this habit could become something you actually looked forward to?
- How might your life be different if you were to exercise each day for 30-60 minutes?
Asking yourself questions such as these, can be a great way to get yourself out of bed or off the couch and onto the exercise bike. Implementing research-based habit practices can also be very helpful
Author, Charles Duhigg suggests using cues that trigger you to repeat your habit.
The cues Duhigg has found to be especially effective are as follows:
- Choosing a specific time
- Determining a location or place
- The proceeding habit or behavior
- A particular person associated with the habit
- Choosing an external reward that you enjoy
Here’s an example of what an effective habit plan might look like. Let’s say you set your alarm for 7am.
As you’re waking up and still laying in bed, you don’t really feel like going to ride your exercise bike. You feel tired and are so comfortable. But then you remind yourself to think about why you are committing to riding your exercise bike each day.
- You imagine yourself enjoying your body and health in youthful ways
- Perhaps you see yourself playing with your children or grandkids
- Maybe you see yourself doing something you enjoy such as playing a sport or going for a weekend hike
- You see yourself smiling and feeling youthful and energized
You get up, brush your teeth, and walk straight to your exercise bike.
- You sit down and start watching your favorite show or channel. Slowly riding the bike, you relax and get swooped up into the show you’re watching
- After a few minutes, you decide to start riding faster.
- Within 20 minutes, you realize you are sweating profusely.
- Feelings of pride wash over you as you realize you have stuck to this habit for the last 90 days.
- You feel and move so much better than you did just a few months ago
As you continue with this habit, motivation will likely become less important. You may find that your cardio sessions simply become an automatic part of your daily routine. The positive-feeling endorphins that come with exercising regularly might just offer all the encouragement you need.
Precautions for people with knee problems
Make sure you follow the advice of your doctor or medical professional. It may also be helpful to start small with short rides on your exercise bike. To illustrate, for your first week, you may want to ride your exercise bike for 5 minutes or less.
Starting with a long, strenuous ride may cause excess soreness. While tempting, you may injure yourself. Causing your body pain may also cause your brain to associate your new habit as something painful to avoid.
By starting small and enjoying the experience, you’ll be more likely to stick to it as a long-term habit. Put on your favorite music or movie while you ride. This may further help your brain connect feelings of pleasure with cardio bike sessions. You may even find yourself excited to jump back on the bike!
Other tips
As you get in better shape you may want to experiment with pedaling at different speeds. If you are looking to build muscle around your knees, Dr. Ericson, Ph. D., found that increasing the “pedalling rate increased the muscular activity in most of the muscles investigated, generally without changing the joint load.”
In other words, pedaling faster will activate more muscles without putting more pressure on your knee joints. Additionally, Dr. Ericson found that “increased saddle height decreased the maximum flexing knee load moment.”

-
People have found the heart rate monitor on the Exerpeutic Magnetic foldable exercise bike is more accurate than those on other bikes. This can be an important feature if you are looking to get a strenuous cardio work out in. For example, if you want to work as hard as running but find pedaling is kinder to your knees.

- One person said this is the widest, most comfortable seat she has used.

Cons
