Product Description

Product Description

The buttonless technology and beefy hardware make the Protegé 9.0 bike computer your reliable and accurate data source. It’s great for training, touring and keeping track of your car-free miles. Its easy-to-read 4-line display gives you 5 pieces of data (including temperature!) at a glance.

Amazon.com

Whether you are training for a race, using a stationary bike for daily fitness, or just want to know your mileage for weekend rides or commuting, the Planet Bike Protege 9.0 9-Function Bike Computer is the perfect, easy-to-operate computer for multiple uses. A must have for any gadget enthusiast or anyone who is data driven, the Protege 9.0 allows you to track your progress and improvement as you build strength through multiple functions as well as view the temperature and time on one easy-to-read screen. Small enough to fit nicely on your handle bars, but large enough to read clearly, the Protege 9.0 provides all the information you need in a sleek and elegant form.

The Protege 9.0 has a "buttonless" design that allows for a large Macromonitor LCD screen with most of the information displayed on one very readable page. Displaying four lines of information on one screen, the computer provides up to five pieces of data at once without you even needing to press a button. Switching displays only requires a simple tap on the computer, making it is easy to operate in the midst of your ride, even with gloves on. A longer tap on the computer will reset the data. The functions include current speed, speed comparator, ride time, trip distance, dual odometer (for two wheel sizes), average speed, maximum speed, clock, and temperature for up to two different bikes.

The Protege 9.0 makes it easy for you to record and track your trip information effortlessly as you ride. The computer auto-starts when your bike begins moving, and mileage and time stop recording when you stop and restart automatically when you begin again so you can get an accurate reading of your time and distance no matter how many times you stop.

The Protege 9.0 has a two bike capability, allowing you to set the wheel circumference for two different wheel sizes so you can preset odometer readings for both. A single button on the back of the computer allows you to toggle between bikes. An additional wire/sensor harness is all that is needed to use the computer on two different bikes. The computer itself is removable from the holder it sits in and easily switches between bikes.

Built to last, the Protege 9.0 is backed by a lifetime warranty. It comes complete with a heavy-duty oversized wire harness with an 82-centimeter wire mounting kit for the front wheel and a case. The device is ultrasonically welded to be completely weatherproof. Installation is simple with easy-to-follow directions. Combining a clear, easy-to-read display, user-friendly operation, and a sturdy design, the Protege 9.0 is an excellent computer for any biker.

      About Planet Bike
      In November 1996, Planet Bike was founded in Madison, WI. In many ways, Planet Bike began as a social experiment that dedicated itself to doing business in a different way. Instead of being just another company that develops and sells products with profit as its end goal, Planet Bike wanted to help bring about positive change for people, their communities, and the environment.

      Despite being a simple machine, the people at Planet Bike have always believed that the bicycle has great potential to help improve the world and the lives of the people in it. From the start, they have embraced an alternative corporate purpose which seeks to help get more people on bicycles by making communities friendlier places for the self-propelled. By donating 25% of company profits to causes that promote and facilitate bicycle usage, Planet Bike hopes to make an impact.

      Social experiments aside, Planet Bike was born from the heart of a cyclist with a goal of making innovative, high-quality, and practical bicycle accessories. Simply put, the company strives to design and develop the best bicycle products in the world. In the company's short 10-year history, it has made important product innovations within the bicycle industry. Advancements include the four-line computer which is now a standard in the industry and the world's first self-contained HID light. Not bad for a company that 10 years ago started as a one-man operation. Today, while still a small company, Planet Bike continues to evolve and improve its product line with the goal of always striving to build accessories that make it easier for people to ride their bikes. Since 1996, Planet Bike's financial support of the grassroots bicycle movement has totaled $500,000. By 2010, they have made a goal to donate $1 million to organizations that are dedicated to making America a friendlier place for cyclists.

Great Recumbent Trike Cycle Computer
5 Stars
Great Recumbent Trike Cycle Computer
Despite some people's reviews, I noted that Utah Trikes used this on a lot of their recumbent trikes. Although did not mount mine on the left handlebar as they did. Instead ordered an Issimo Designs NOB Universal computer mount (from Amazon) and mounted that to the left TerraTrike Versa Bar, and now have a better placement on a slight angle that is out of the way of my big thighs. Used a spare CatEye rubber gripper instead of the provided rubber spacers because I preferred the extra lip for when I go trail riding (off road).Everything works as intended. I did have to measure the distance manually, which was rather easy. There is a slight different using this and CycleDroid, but the way the solar activity affects GPS signals who is to say whether GPS is more accurate (Moto G4 Play) than this Protege 9.0 computer is. Do wished this one had a grade percentage (i.e. +/- 6%) grade meter on it as well.The temperature is a good feature that I'll probably use more when it gets cooler. Notice when it went over 100° F the meter was like 05 instead of 105, but that's a minor thing.Resets well. Setting up was easy. The meter is working good on a TerraTrike Rover i8. The cadence thing is about accurate. Some days I don't have it in me and I can feel it, and the up & down arrow confirms it.Found out a way for a night light: use a USB powered LED light connected to a battery booster pack. A few rubber bands and velcro straps holds that right in place, but not worries about a back light - back lights drain batteries more.This cycle meter does everything most others do, and for more stable than the twist-on Sigma that this one replaced. I do not take this one in and out of the mount much. If one did the plastic nock might wear down over repeated usage and one might have to employ a wide rubber band or wider silicone seal. That would be the only issue I'd see over time.Haven't taken it down the Weiser River Trail yet, maybe in September. Am confident this cycle meter will preform well.Am pleased. Also corresponded with the manufacture on mounting options before I found The NOB and they did get back to me with photos and links. So customer service was great as well.

5.0 out of 5 stars My 2nd Planet bike Protege 9.0 I just love it and it is easy to read without my reading glasses!
Reviewed in the United States on April 13, 2020
Overall I am very pleased with my Planet Bike Protege 9.0 and think it is a great value for your money. I had a Planet Bike Protege 5.0 in the past so I knew I would love this Planet Bike Protege 9.0 bike computer and I really do. I normally wear reading glasses like when sitting in front of my computer, or my cell phone and this screen is very easy to read even in the Florida sun. My first one is mounted on my recumbent Easy Racers Tour Easy (cord mount distance is 40 inches / 102 cm from mount to fork) and so I had to buy the extra long cord so if you ride a recumbent be sure to measure the distance from wheel mount to handlebar mount so you will know if you need the extra long cord or not. cord mount does come with rubber inserts for mounting on smaller diameter tubes of some handle bars such as on a recumbent. My pictures are from my Tour Easy mount. My second Protege is on my (new to me) Recumbent Cycle Genius RDX and again I bought the wired version and had to purchase separately the longer wire for the computer to mount on my recumbents handlebars. I included the back of the computer so you can see the 3 silver contacts and the two red setting buttons to reset the computer and to set the wheel size, also you can see that you can change the battery without a tool to open the battery compartment - I think that is a really smart idea even though I carry tools with me all the time. And it is easy to read without my reading glasses! It also tells you the temperature which is nice to know if you live in Hot Florida like me.
