Hi all long time.....
So I was at the physio on Tuesday and effectively I'm starting cycling again after *cough* some umm... 15 years at 69. it seems I have an arthritic knee that is now also exhibiting a "Bakers cyst" so I need to strengthen my knees up.
I used to have a heart monitor which had a chest strap and a sort of watch display that went on the handle bars, do they still exhis as canna see one on the sites?
Cheers
Pete

They exist because pretty much any bike computer will have the facility to display HRM data from a chest strap. Wahoo Tikr straps are pretty good.
You're probably remembering Polar HRMs.
-
Another option is a handlebar mount for your phone, then you can use that to display heart rate from a Bluetooth-linked chest strap.
-
Something like this
https://www.cateye.com/intl/products/computers/CC-PA400B/
You’ll need to get a Bluetooth HR chest strap to go with it.
-
Here's a review of HRMs (https://www.cyclingweekly.com/group-tests/heart-rate-monitors-351068).
And here's a review of computers (https://www.cyclingnews.com/features/best-cycling-computers/).
You can pretty much mix and match, as long as the computer will receive data from an HRM, which most will. Many will do mapping and navigation as well - it all depends whether you just want the data recording, or more.
-
You could also consider a smartwatch which will both record your rides and your heart rate as well as just sit on your wrist and behave as a wrist watch too. You can for most if not all such watches add a chest strap for when you ride but unless absolute HR accuracy is critical it's not a big deal these days. The tech is very good.
No idea what your budget is but I recall Finch was selling a Garmin which will do all you want or of course cheaper alternatives are out there.
-
I'd also suggest a sportswatch, unless you want the info on the bars. if you do, it doesn't have to be a chest strap, there's plenty of arm options available if you find that more comfortable or convenient. I have a Scosche Rhythm, an older model than the current one, works fine with Phone or Garmin.
-
I have a wahoo tikr. Cheap at 30 quid, connects to my phone.
I can record workouts, which I find useful for tracking actual fitness.
Via the wahoo app, there are options to monitor heart rate - and of course I can put my phone where I can see if if required.
-

I've not found even quite a good Garmin watch to give readings similar to a chest strap. I tend to regard watch readings as interesting but not particularly reliable.
-
The inaccuracy of watches for measuring HR is legendary but many tester find good correlation. I find my watch is almost identical to a chest strap. The only problem is when running in the very cold when it loses the pulse and locks to my stride.

£17.99 for a watch and hrm belt. I used a similar Decathlon product successfully for a few years before going 'smart'. Simple and effective. Mine came with a handlebar mount - I've a spare mount you can have for free if you need it.
-
Thanks all. I will use a chest strap and really I want a unit on the bars to look at as it's what I had in the past and it worked well then. I am not intending using my phone for this stuff as I am too worried about damaging it. I'm not at all concerned with "data" as if I manage to get up to five or ten miles by Spring next year I will be happy enough. It's really about building some knee muscle to cope with the Bakers Cyst I have now got. I'll repeat my MIL's advice all, Don't get old. Trouble is she never told me how to avoid it....

To get old you need a bit of luck. Ageing painlessly and with dignity requires even more in the way of good fortune.
Hope all goes well for you. Muscle up😉
-

I found the same with the Scosche arm monitor, mated with phone or Garmin, I had a chest strap before and disliked the feel of it. I ran them side by side as a comparison for a couple of rides, the only difference was the armband lagged a bit, by a second or two, not enough to concern me.
-
At one point, I had an electric wrist watch and a heart rate monitor, with a 'wristwatch' type display.
If I wore both together, the HRM would detect pulsation from both the watch and the chest strap...
-
Gang I am struggling here to find a computer sub £100 with the heart function. I literally gasped at the £750 Garmin unit. Good grief what makes that so special?
Suggestions please.

As the Red Baron is an awkward shape, I use a wireless bike computer instead of a proper wired one like dog intended. As bike computers with nearfield wireless sensors are universally shit (even on a DF bike with no lights), I found one that used proper ANT+ speed and cadence sensors. As a bonus, it also understands ANT+ heartrate and power sensors.
This would appear to be the current model: https://www.trekbikes.com/gb/en_GB/equipment/bike-accessories/bike-computers-sensors/bike-computers/bontrager-ridetime-elite-cycling-computer/p/21830/
Note that this just does the normal bike computery things of instantaneous readout and trip averages. It doesn't have a GPS receiver or any ability to download data, runs for a year or two on a CR2032 battery, and is relatively unlikely to get nicked. (Things have got needlessly confusing in recent years, as what we would normally refer to as "GPS receivers" are now being marketed as "Bike computers".)

I have no idea how reliable my Tickr HRM is, but over a year or two it does appear to have been very consistent. I'd like to think it overreads because lower rates sound more impressive. Otherwise, I don't care.

If all you really need is HR figures, you don't need a computer. Just buy a hrm/watch from Decathlon for £18 (see my earlier post), strap on the chest belt, fasten the watch to your bars, and it will display your current HR in big figures. I did that for years.

This one should be suitable for your needs @ £17.99

That's the one, De Sisti. I tried unsuccessfully to import that screenshot earlier. Thanks for being more competent ;D

Well I don't know about sub 100, but I have a garmin 530, which will read my chest HRM, the 530 comes in around £200 currently, HRM at various prices, depending on new, second hand but still boxed, refurbished or potentially conterfeit on aliexpress. but should be between 500 and 100. so far less than the 750, what are you getting for that?
-
The cat eye I linked can be had for £75, then you need to:add cost of Bluetooth HR sensor.
-
https://www.wiggle.com/p/garmin-rally-rk200-power-meter-bike-pedals £700+ sorry I was getting screen blind at this point.
I'll have another look at that Cateye unit. Purchase made and with the discount (some £20 more on Amazon) I for the unit and strap for £97. Just need the bike now.
Thanks

The inaccuracy of watches for measuring HR is legendary but many tester find good correlation. I find my watch is almost identical to a chest strap. The only problem is when running in the very cold when it loses the pulse and locks to my stride.

A pedant would note that it's not an ECG if it's measuring bloodflow optically.

Apple Watch does both.

Shirley that would need a second electrode?

1 electors but a connection through the other hand. Validated as a medical device by American FDA

Ah yes. I just looked it up, and remembered it from last time I looked it up (and then promptly recycled the neurons). You've got to sit there with a finger on the not-a-winding-knob to complete the circuit for the duration, which makes sense.

“ A heart rate under 50 BPM or over 120 BPM in ECG version 1 affects the ECG app’s ability to check for AFib. In ECG version 2, a heart rate under 50 BPM or over 150 BPM can affect the ECG app's ability to check for AFib.”
Interesting, as many of us who regularly exercise have resting HRs under 50 bpm.
-
It annoys me that Garmin, whilst knowing that fit people do have low resting heart rates, didn't bother programming on my fancy watch the ability to flag an alarm for a really low heart rate any slower than 40. When I'm asleep, my heart rate is around 37.
-
When I got knocked off my bike and carted off to hospital my HR was so low they believed I was dying but really I was just resting.
-
One day I'd like to be one of these fit people. I think mine gets down to 70 occasionally.
-

I had a bypass four years ago, and the follow-up over the years since has occasionally run up against the fact that mine can certainly drop to around 40. A sibling who probably exercises less is being investigated for a different reason, and has had the same experience, so I'm not sure whether, for me, it's being super-fit (I wish) or just genetic.
-
Probably a combination of both.
My Mum has never really done formal exercise.
I saw an ECG from when she was a teenager, in the '50s.
She had a rate of 45...

MrsC is the same.
She also has impressive muscle tone for someone who never exercises.
I turn into a blob of not-quite-set jelly if I skip exercising for 3 days in a row, and my resting heart rate is over 70 (the only exceptions to that were when I was doing 15-20 hrs a week of hard exercise).

Do you have a high max, something like 190 or 200 bpm?
-
Do you have a high max, something like 190 or 200 bpm?
How can you tell? "your heart has ruptured because you exceeded max pulse rate"
I guess 'yes', because if I have a hard perceived effort, my pulse will go over 180, and sustained 165-170 is normal for me. I'm 56, so that is high for age.

Similarly, I can reach 190 if I work hard, and easily sustain over 160. I'm *pauses for a maths break* 44.
-
*Shrugs*. I go ~40 to ~165 and Mr Smith (who is much older) goes ~60 to ~185
Not a lot in it, really. The 'best' measure of heart fitness is how fast your HR drops to normal after exertion.
-
When I bought my first HRM in 1990, I'd top 180 on the 2km commute to work...
-

Yup! Anytime anyone reaches for my wrist to take a pulse, I forewarn them that it will be really low and they haven't miscounted, and yes, that's normal.
I do have an emergency contact tag on my wrist - perhaps I should get a warning line about my heart rate added to it?
-
Some very impressive numbers around.
I just want to avoid a heart attack as I set out on my first ride for *blush* at least ten years and also over weight.

Resting is around 40-45 for me, dipping to high 30s when sleeping. I've always had a fast recovery to resting too, despite always being moderately overweight. At school the PE teacher didn't believe my figures when we did a test involving measuring resting heart rate, two lengths of the pool as fast as possible, then heart rate every minute until back to resting, as I recovered faster than those who were good racing swimmers. He thought my partner for the test was counting it incorrectly. So it's a bit weird, back then I was endurance fit to do long bike rides or long swims, but couldn't do anything particularly fast, and running was right out, but really good dynamic range and responsiveness on my heart (I assume there's some actual medical term for that).
I find it hard to go over 190 for the last few years; typical peak effort on a ride is now about 185 (I'm mid-50s), whereas a decade ago when I was doing a lot of Audax riding I'd hit 195 on steep climbs - though this was not sustainable for more than very short periods. When I did a VO2 max test as part of a drug metabolism study about 12 years ago, they stopped the test when I was at 210 and they ran out of bags to collect my exhaled breath. The postgrad uni students doing the testing looked quite worried and kept asking if I was OK...

My Wahoo monitor has been reliable and relatively comfortable.
However, the Wahoo Fitness app recently upgraded. Since then it doesn't display the 'Time in Zones' properly, putting 100% of the time in Z1.
The heart rate is being recorded properly, and is shown in a graph.
Historic recordings are fine, it is just anything since the upgrade.
Bloody annoying.
