Planet Bike 9.0 Wireless computer


Reviewed By: Michael Gormley on 7/25/12

Works well. Installation not difficult - pretty good instructions. Large Sensor was a little tricky to align with the wheel sensor. You do need to turn the unit on frequently - a slight inconvenience. Temperature will read high if in the sun. I have a brown burn mark on the screen from the sun from a couple month's use. Otherwise, simple to use and am satisfied with the performance.

Average Computer

I agree with a previous review, that thw wireless 9.0 is average at best. Good read out, but due to only having a max distance of 21", it is far away on my recumbent. Also the "hard" shut down cannot be changed and if it sits more than 5 minutes, you have to manually turn it back on, or won't record. I bought it soley because my bike disassembles and it is 1 less thing to mess with. Temp is not accurate either .

Planet Bike Odometer


Reviewed By: Mike Cruz on 12/6/11

I have been using Planet Bike odometers for over 15 years. The temperature function is my greatest need when riding or on tour. The wireless 9.0 is a super device, no problems, has great readouts. I would recommend to all.

Overall this is a decent bike computer, however I have two critiques and then will tell you about what I do like about it. Max Speed: The computer seems to think that I can ride 99 miles per hour. This may just be my computer, but the max speed function is suspect at best. Turn Me On: The computer has to be prompted to turn on with a push. I imagine this feature extends battery life, but why can't it just go to sleep and wake up when the front wheel begins spinning. Likes: Thermometer - I am not sure if it is super accurate, but it is nice to know what the temp is. Display - large and easy to read.
