Frequently Asked Questions (FAQ)

What is the best bike computer with cadence?

Cadence is a term used to describe a cyclistʼs pedaling RPMs (revolutions per minute).

Bike computers with cadence do an excellent job of displaying not only how fast you are going but what cadence you are pedaling at.

The average human being has a cadence of about 80 to 100 RPMs.

It is important to set a specific target RPM for when you are riding and make frequent assessments of where you are while keeping this target in mind.

Why is this so important?

Inefficient pedaling results in you having to exert more energy and increases the chances of serious injury and extreme fatigue.

The best bike computers with cadence have backlit displays are easy-to-read and contain multiple functions, such as speed, distance, time and calories burned.

What cycling computer do pros use?

There’s no need to go overboard on the newest and the fanciest cycling computer available for your bike. By now, the technology for such products has been fairly mainstream for quite some time and can be found throughout the industry. In fact, the same product is used by pros and amateurs in almost equal numbers.

You may have noticed bicycle components and cycling as a whole has a tendency to run toward the most complex, least intuitive option available at the time. Take this mindset and apply it to a bicycle computer and you’ll probably be in the mindset of the vast majority of cycling enthusiasts.

If you are one of the few who doesn’t need an alarm clock to wake you up in the morning, a stereo system to listen to music, and GPS navigational features on your bicycle, then you’re the perfect candidate for a bicycle computer.

Do I need a GPS bike computer?

GPS bike computers have been gaining popularity over the last few years. They range in price and functionality, so you can get exactly what you want without breaking the bank.

This type of computer includes a GPS system, which uses satellites to track your progress. The majority of these computers have limited navigation tools built in, as well as options for tracking your heart rate.

While most GPS systems are pretty basic, they’ll get the job done. The only main downside to them is the need for a power source.

To use these, you’ll need to either rely on disposable batteries or use replaceable rechargeable batteries. The good news is that the latter option means you won’t have to worry about losing power midway through your ride.

What Garmin bike computer should I buy?

There is an overwhelming amount of choices when it comes to picking the best cycling computer, which can make the decision even more difficult.

The product you ultimately choose depends on your needs, but these two have consistently been amongst the best over several years and much thought has gone into their design.
