Erdefen said:I'm looking for info on the above, I would like to have something I can clip on to the handlebars
and with readouts big enough to read without using my reading glasses. I would like it to have 2
readouts one to give info on the bike, eg, instantaneous speed, ave speed etc, the other display to
give info on my body eg instantaneous heart rate, memory of heart rate with maximums etc.
Quoted message said:Does such a thing exist? Does anyone have experience of using such a device with ref to
reliability, accuracy, price etc. Recommendations and/or constructive criticism would be
appreciated. Is there a website I can consult? As I am new to biking and of advancing years I feel
I need to be reassured by the info that this type of device might give me and might enable me to
increase my fitness level safely
I'm sure such a device exists, and I'm sure it's very expensive!
As an old git with a heart problem who mustn't exceed a certain amount of exertion I have the same
problem. But the problem with HRMs is that my problems (angina, atherosclerosis) are only loosely
linked to heart rate. For example, generally speaking, it would be dangerous for me to exceed
150bpm, risky to exceed 140bpm for some time, and perfectly safe to trudge along at 130bpm for
hours. Except that sometimes my heart is a bit wobbly, and exceeding 100bpm feels pretty unpleasant,
and I need to sit down and rest. And usually 140bpm feels strenuous, but on a good day it feels
fine. According to my cardiologist, what it feels like is more important then numerical bpm, which
seems sensible to me.
However, I bought a cheap HRM (low end Polar), and wore it everywhere for a while. As a consequence
I learned to be able to guess my heart rate to within plus or minus 5 bpm. Now I only wear the thing
ocassionally, just to check that I'm still guessing right, or to do specific tests to see if the
ticker is getting better, e.g., recovering faster, or doing same work at lower bpm.
A cheap cycle computer plus a cheap HRM with a handlebar mount for the HRM "watch" will give you the
displays you want quite cheaply. Immediate figures are only a rough guide to what you really want to
know, confused by all sorts of noise factors such as wind, temperature, humidity, fatigue, last
meal, etc.. Long term trends are much more useful, but for that you don't want more expensive
devices on your handlebars, you want a proper computer with spreadsheet etc..
