Sigma Bike Computer Features | How technology makes riding even more fun

Cycling / Ideas & Advice


I was inspired to purchase my Sigma bike computer – the BC 1009 last year after an exhilarating downhill run when my riding partner shouted out something like: “48 miles per hour, baby, YEAAAAAAAH.” Having that information at your handlebars fascinated me and after 975 miles, I can safely say that my Sigma bike computer is one of the best purchases I’ve ever made.

Total Odo

In addition to tracking my total miles, my BC1009 bike computer also keeps a running tally of how much time I’ve spent on my bike which is a really cool and motivating statistic to look back on. I’ve said many times that cycling is the most enjoyable way to burn calories and it’s fun to see just how many miles I’ve logged and how many hours I’ve spent in the saddle both cumulatively and on my individual rides.


Speaking of motivation, I like knowing how fast I’m going and not just on those spine tingling downhill sections. When I’m working hard and hating life on a steep incline, I challenge myself to keep my speed above 9mph. It doesn’t always happen, but it’s a nice bit of instant feedback to keep me focused and inspired to pump harder and do whatever I can to boost my next favorite bike computer stat, average speed.


Big group rides are organized by average miles per hour so knowing what you’re capable of is an invaluable piece of information that a bike computer can give you. The last thing you want to do is head out with an 18mph group when you’re a 14.99mph rider like me. Granted, the only way to get faster is to ride with faster cyclists, but understanding your average speed can remove a lot of dust from your diet.

Finally, there’s the feature that hooked me to being with, TOP SPEED. I can’t lie, the pure speed of road cycling pulled me back into the sport instantly and continues to be main reason why it is my favorite outdoor activity. At the end of a ride, I enjoy scrolling through all of the features to see what stats I put up and top speed is always the one I look forward to seeing most.


Since my Sigma BC 1009 bike computer is such a valuable tool, I really appreciate the fact that I can take it with me when I’m parking my bike in town. All I have to do is push down on the top and twist to the left and the computer pops right off for safekeeping while I’m away from my bike.

Twist and Lock

Best of all, the $29.99 Sigma BC 1009 took me less than 15 minutes to install and calibrate to my tire dimensions. The sensor attaches easily to your front fork and the magnet clips onto one of your spokes in seconds. From there, you simply adjust the magnet to a 1/4″ gap and you’re on your way.


If you don’t like the look of the wire looped around your fork, you can go for the $59.99 wireless STS model that gives you all the same features I’ve described here.

I’ve been profoundly happy with my Sigma BC 1009 bike computer. The lithium ion battery lasts for two years so it will never die in the middle of a ride like my smartphone does routinely when I’m tracking my ride with Strava. I’d recommend it for everyone from casual riders who just want to know how fast they’re going at any given moment to serious riders looking to boost their performance goals.

If you’re thinking about buying a bike computer, I hope this post was helpful and if you have a computer you love, please leave a comment and tell me about it!
