Bell Spinfit Calorie Speedometer Instruction Manual

Filed under: Misc. Gadgets — Laura Moncur @ 5:00 am

View speedometer details at AmazonI have received so many comments about my Bell Spinfit Calorie Speedometer asking me if I could email them the instructions because they lost their manual and their battery died. The Bell company’s website is worthless for instruction manuals, so I have scanned mine in. The most important page is below:

Bell Spinfit Calorie Speedometer Instruction Manual page 12

These are the secret codes that you have to program into the speedometer to tell it what size wheels you have. If you get the wrong code, you end up with the wrong mileage.

The rest of the important pages are here:

Bell Spinfit Calorie Speedometer Instruction Manual page 5

Bell Spinfit Calorie Speedometer Instruction Manual page 11

Bell Spinfit Calorie Speedometer Instruction Manual page 12

Bell Spinfit Calorie Speedometer Instruction Manual page 15

I hope these help you and you are able to reset your speedometer accurately. Good luck!!

(Thanks to those who posted helpful comments on the previous post.)

Update 06-27-06: A most grateful thank you to Ken Miller who emailed me this .pdf of the ENTIRE instruction manual.


  1. Thanx for the info on the settings. I know I have the manual somewhere, isn’t it always somewhere else? I have to reset it because I’ve moved it from my son’s 20″ bike to a new(used TREK I just bought him.

    However, I have a question. According to the manual, the setting for a 700mm x 25 wheel is 2124. I thought you just had to use the circumferunce of the wheel as the setting (700 x 3.1414 = 2198.98). I’ll go with the manula’s setting, but I’m just curious. Thanx again.

  2. Thank you SO much for putting this out here! I also lost my instruction manual and I need to replace the battery, so all the settings will reset. I had NO idea how I would figure it out. And you are right– the Bell website is useless. Thanks again!

  5. I just got 2 BELL speedometer’s and I can’t get any of them to work. All it tell’s me is the time. I have tried everything and nothing works. How do you get them to register?

  6. Thank for this information. Very useful when switching from one bike to another. I thought I was going to have to buy another one.

  7. i have a recumbent trike and the front wheel is 16 inches, i am having a problem finding the wheel factor. not sure how to figure this out

    Comment by Greg — June 23, 2007 @ 5:11 pm

  8. figured it out, all i needed to do was get a millimeter converter, very easy lol

  9. I had to replace the battery in my speedometer and discovered that I had misplaced my instruction guide. After an initial internet search, I was about to give up until I ran across you piece. I was able to feel my way through the set-up but was boggled by the tire setting. I am so glad that I found your posting and thankful that you provided the scan of your guide.

    Thank you.

  10. Thanx for the info… I’m resurrecting my old Genesis 18 speed ATB that was flooded up to the gooseneck after Katrina. Here it is almost 2years later and the Bell speedo, which I had given up for junk, suddenly started registering… As you and others have stated, the Bell site is great… if you want a helmet. Your efforts are appreciated more than you may ever know!

  11. unit was working great. now 8’s appear in upper and lower screens. have changed battery and pushed resets to no avail. thanks

  12. Robert,

    I’ve never had that happen before. Sounds like yours is toast. Luckily, they’re only $20 instead of those overpriced cycling computers at $120 that don’t do anything more than the Bell SpinFit.


    Comment by Laura Moncur — July 23, 2007 @ 7:56 am

  13. Thanks so much! I have an older bell speedometer, and the numbers from this manual seem to match up with that one, too.

    Comment by Mike — August 12, 2007 @ 12:25 pm

  14. I have a Mongoose 26″ bicycle how do I know what code to use? The tire says 26 x 1.95


    Comment by Paul — August 27, 2007 @ 11:37 am

  15. Would be nice to know how far in to put the sensor?

    Comment by Fred — August 28, 2007 @ 9:57 am

  16. THANKS!!! I misplaced my Spinfit instruction manual and just purchased a new bike which I want to use it on. This manual is VERY VALUABLE

    Warm Regards, Gary

  17. I have changed my bell from one bike to another that i just got and i can not get it to register on the display.

    Comment by jack — December 21, 2007 @ 12:10 pm

  18. Jack,

    Try moving the sensor closer to the magnet on the spokes.

    If that doesn’t work, check the cable to make sure there isn’t a short in the wire.

    Best, Laura

  19. First, I have looked for a year and a half for a battery! Second, I lost my manual too…THANK YOU for posting this information. For a while today, I thought I bought a battery for nothing. Thanks again.

    Comment by tami — February 2, 2008 @ 5:44 pm

  20. Thanks your info helped out a lot. Looked all over the internet for a Bell website. then came across yours. Had to change battery and was lost as to how to do it.

    Comment by juliebarkey — March 31, 2008 @ 5:19 pm

  21. Does anyone know what the wheel factor is for a wheel diameter of 27″ (700 x 38c)?

    Comment by Ed Grossmann — May 25, 2008 @ 10:37 am

  22. I mistakenly bought a Bell speedometer for my mountain bike. It works, but only as long as I keep it under about 17mph. Once I go over that, it seems to lose its place and read 0 until I slow back down again. Any idea what causes that?

    Comment by Andrew — June 9, 2008 @ 5:00 pm

  23. Thanks for the help! I’ve been trying to set my speedometer for a while. I got it at a garage sale, and the guy said that it was really simple. He said that I didn’t need the book because it was self-explanitory. I foud out that he was very wrong. Thanks again.

  24. Your are the man!! Battery died, manaul lost. You know the story. Thank you so much!!

    Comment by Brian Lee — June 21, 2008 @ 3:17 pm

  25. The Bell website is USELESS!!! thank goodness for people like you who take the time to publish those lost manuals that most people either lose or throw away. Thanks Again great site!!!

    Comment by Rob — July 3, 2008 @ 1:20 pm

    Comment by Chuck — July 3, 2008 @ 5:51 pm

  27. okay. i had this on my bike and then i took it off b/c the computer itself went through the wash in my pocket so i took it all off. so now that its dried out and i got a new battery for it i cant seem to get the code right. i have a 16/2.25 and i used every 16 inche code. none worked.

    Comment by kevin — July 20, 2008 @ 5:51 pm

  28. Andrew (June 9), I had a similar issue on my mountain bike when off road. Turns out the extreme jarring/brush occasionally moved the sensor away from the magnet. After adjustment, fine.

    Thanks for the site!

    Comment by Paul G Sachs — August 2, 2008 @ 4:09 am

    Comment by ELAINE — December 31, 2008 @ 1:24 pm

  31. Thanks a million. Going on a 400 mile trip on the oregon Coast with the Boy Scouts. Had to put a new battery in. Bell website was useless. thanks again!

    Comment by Timothy Benjamin — June 6, 2009 @ 12:53 pm

  32. I got a speedometer a few days ago and no matter how much I move the sensor and magnet, the speed reading stays at zero. Can you help?

    Comment by Carson — June 16, 2009 @ 8:57 am

  33. Anyone know the size/number of battery to replace in The Bell Spinfit Speedometer? Thanks!

    Comment by LT — June 21, 2009 @ 10:49 am

  34. When I opened up the full instruction manual PDF the pages were upside down. Anyone know how to make them right side up again??

    Comment by Tanner — July 20, 2009 @ 6:33 pm

  35. Yes, LT, the battery is an LR43. They can be bought at Radio Shack for around $5.00.

    Comment by Tanner — July 20, 2009 @ 6:34 pm

  36. THANK YOU so much for posting this — I, like a lot of people here, lost my manual (I’m so glad there are people that can keep up with these things) and have lost my settings! You are a lifesaver!!!

    Comment by Melanie — September 12, 2009 @ 6:02 pm

    Comment by george blackshields — September 19, 2009 @ 2:57 am

  38. Can someone tell me what the code for the tire size 700X45C?

    Comment by Robert — June 7, 2010 @ 6:00 pm

  39. Just bought a cannondale off craigslist with one of this guy still installed! Thanks so much for the info. Is there any way to manually turn it off? I’d like to do that rather than leaving it sit for 5 minutes.

    Comment by Joe — June 13, 2010 @ 12:20 pm

  40. Thanks for the info. I misplaced the instructions and my son got a larger bike. The set up code are most useful. I am saving this to my favorites
