The problem went away after a firmware update. The most likely interpretation is that the reed switch is generating two pulses for each pass of the magnet, but now each double-pulse is interpreted in software as a single pulse. It's not ideal (hardware with one defect has a higher chance of also having other issues), but it's accurate.

I am also searching for a computer with non-volatile memory. According to Sigma the computers BC 5.16 BC 7.16 BC 7.16 ATS BC 9.16 BC 9.16 ATS PURE 1 (according to the reply from Sigma customer service) do not save your values after a battery change (however, you can manually set the odometer). And following Sigma computers retain data: BC 14.16 BC 16.16 ...

For your requirements this would work fine. The speedo readout would not reflect a real-world value, but for comparing efforts on the same bike it would be ideal. I'd suggest the lowest priced wired Cateye bike computer (velo9 or similar) because it lasts years on a battery. I've had cheaper bike computers, and they can eat batteries in a few days. For ...

The bike computer app I use will do almost all of this: IpBike. It's not free long-term, but you can try it for free for long enough to know whether you like it. Its "Workout" mode allows you to set a target speed (or cadence, heart rate, power) specified as a range, and have feedback when you're out of range. This could be as an interval in ...

GPS-based computers, which are often called head units, typically use two communication protocols: Bluetooth (which is the same as many personal electronic devices like smartphones use) and ANT+, which is a protocol developed for the cycling world. I think that ANT+ was initially developed for power meters, but it can be used for other devices. ...

Putting the sensor on the crank would work in principle. In terms of if it would mean anything in the real world, you'd first have to ask what has real world meaning on an exercise bike, anyway? Even with an actual multispeed bicycle on a trainer roller, what significance does the tangential speed of the tire really have, anyway? Really, in a simulated ...

Either is fine - in fact on this timescale there's not much difference. My suggestion: I suspect that what's most satisfying for your body and your desire to measure will be somewhere between the two - probably something like 2300 Cal on your off days and 2900 on your riding days. This should be quite achievable - a handful of cheese added to your pasta ...

The bike computer is based on the relationship between altitude and air pressure. Even though it has 1 meter resolution, it is still constrained by the air pressure around you. About 11.3 Pascal difference in air pressure is counted as one meter. One thing to consider is that most houses have a slight 10 Pascal negative pressure caused by the ventilation ...

I had a problem with a low-end wired cateye computer. It would work fine for a while, and then occasionally my reported speed would be 50% higher, bursting to 100% higher. I even saw 90 km/h once when I was riding at about 30. Fortunately I have a couple of these, and managed to isolate the problem to the sensor, not the magnet nor the head unit. Since ...

My answer is a little late to the party, but it is worthwhile to note that there were computer (oedometer, to be precise) that are installed directly into the stem: They are out of production, but who knows, maybe the mold are still in some drawer in some far-east manufacturing site and they will reappear soon...

VDO m-zero mounts permanently (cable ties).

It sounds a bit like you want the computer mounted centrally and in front of the stem. As you know Wahoo computers all come with an out front mount that attaches to the handlebar. I think that you are looking for something that doesn't clamp there, perhaps because you have accessories. In general, Googling for "out front" mount should identify most ...

There are two causes of extra counts: Reed switch double closure Radio interference (in an analog radio based wireless cyclocomputer) The source (1) can happen all the time or rarely. If the magnet is incorrectly oriented, it may happen all the time in such great proportions that the speedometer and thus odometer reads incorrect values. In this case, the ...

Your phone would be great for navigation, but not so much for working with sensors. I have had good luck with Garmin (1030 - I figured if I was spending that kind of money, do it once vs. getting a cheaper model that I may want to upgrade later) head units, but I do not primarily use it to navigate. I like the metrics it provides. I usually plan my route ...

We try to avoid specific product recommendations here, but there are a number of computer mounts that attach directly in front of the stem's faceplate, through a pair of extra-long bolts into the stem. Also, Ritchey makes a universal stem mount (which mounts the same way). You could combine this with a 3D-printed GoPro adapter.

i use my mobile phone and bought a universal bike phone holder which sits on the handle bar,i use 3 different apps (not at the same time) strava, relive and komoot, all have a free app or paid subscription personally i prefer strava because you can download the data to a pc then upload to relive to create an videomap of your trip, photos can be included ...

On a Desktop, I would highly suggest gpx.studio https://gpxstudio.github.io/ if you ever need to edit your Strava maps. On my first 3mi run, I had a problem with my GPS and was easily able to correct and input an honest time/pace ( before I edited it, it said I had a 3min mi pace... not even close to what I really did. I then changed it up to a little under ...
