Question: Is this a wireless device?
Document: Also there is a wireless version of this that my son has, and I don't like it as much because you have to remember to turn it on before you start riding or it won't track your miles, and the wired version always starts automatically. Also, if you want longer battery life, shy away from using the backlight, after a few years I could tell the battery was straining with the light and the cyclometer would sometimes dim and reset if I held the light too long.
I have went with the 26 inch mountain bike and it seems to be ok. A nice little computer. It turns itself off when not in use and will turn on as soon as you start peddling. I was considering getting a wireless so I would not have to worry about running the wire down to the magnet, but decided to get the wired. The reason of this decision was that I only needed to replace the battery in the computer itself. The wireless requires two batteries. The manual and other instruction on the Internet says to place the magnet 2 mm from the sensor.
This is an easy to install and easy to read bike computer...takes about 15-20 minutes to install...as the previous reviewer stated, the little magnet (the one on the spoke) must pass over the TIP of the sensor (the part on the fork), not the middle...the tip is the end without a wire on it...there is a little arrow on the sensor to show you exactly where to align the two pieces...takes a while to program and learn all of the functions but you most probably won't use them all anyway...don't lose the instruction booklet!...wireless models are available if you'd prefer less clutter.
It has been too long since we bought it to return it to Amazon. NH Gateway Merchandising, if you are paying attention, I'd be willing to try another one and would change my rating. UPDATE: Within 1 hr of this review posting, NH Gateway Merchandising emailed me that they have authorized Amazon to send us a new device. If that one works, I intend to change this review.
Works well for what I need. Allows me to guage how my progress id going and helps to increase my goals.
With tax and shipping still only about $17. I just bought another one for my new road bike.
We were seeking a simple odometer but found this one and it works great! We've had it installed for a week now; hope it lasts. User manual a bit vague.
We added this on to another order back on April 23 for an "end of 2nd Grade" present for our son in June. Opened June 15 (one week ago). It has not worked. I'm a handy person - and also watched (3) YouTube installation videos, including the one from Bell. Screen is fine, no action from the sensor/magnet. Customer Service said to replace the battery anyway, bought a new battery, and it still does not sense anything between the sensor and the magnet, even 1mm apart, perfectly aligned.
Those interested in more advanced features should probably invest in a higher end computer.
This speedometer works great. Very easy to use and has lots of extra functions. Great deal for the money it costs.
Answer: yes
