Good heart rate monitor option for indoor training, or if you don't get on with a chest strap

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

The TICKR FIT is a new heart rate monitor from Wahoo, which uses an optical sensor and goes on your arm. Your arm! I know, right? Anyway, it's accurate and comfortable, and it might be just the thing for indoor training, or if you don't like chest-mounted heart rate monitors for whatever reason; our non-scientific polling suggests that there's a fairly small but not insignificant minority of people in that camp.

  • Pros: Accurate, convenient, comfortable to wear, easy pairing with ANT+ and Bluetooth
  • Cons: Potential jacket sleeve+wrist strap issue, tan lines...

The TICKR FIT is rechargeable, and comes with its own charging cable which attaches magnetically to the sensor. Having a proprietary charger means you'll need to remember where the lead is, and you can't charge at work if the lead is at home in your drawer of useful things, but you shouldn't need to charge it that often: Wahoo claims a battery life of 30 hours, which should see you through most rides you'd reasonably need a heart rate monitor for. If you're doing a two-day sleep-in-a-hedge audax, your heart rate is probably the least of your worries. In testing I found the battery life to be very good, although not quite up to the 30-hour claim.

The TICKR FIT broadcasts on both ANT+ and Bluetooth, and it's a piece of cake to pair: press the button to turn it on, the LED flashes blue and you're away. Hold the button down until the LED flashes red, and you've turned it off. Simple enough, though if you're used to a chest HRM that fires up and powers down automatically, it might take a couple of sessions to remember to turn it off at the end if you're anything like me. I found the connection to be stable on both protocols, with no dropouts either in or out of doors.

Optically speaking

The TICKR FIT uses an optical sensor. Where a chest-strap HRM is basically a pared-down ECG machine, detecting the electrical signal of your heart beat, an optical sensor shines light into your skin and uses an algorithm to work out how often the blood is pulsing through your veins. When optical HRM sensors first emerged they were a bit, well, guessy. Nowadays the tech has moved on. Both are very accurate.

Electrical sensor HRMs rely on a good connection between the electrodes and the skin, so you have to make sure they're moist: not an issue when you're sweaty, but it can be when you're starting a workout, especially if you have more hair on your chest than you do on your head, not that I'd know.

The opposite is true for optical sensors: they work fine when you're not sweaty, but getting sweat on the sensor (especially if it's a loose fit and not in direct contact with the skin) can make for issues, as the sweat can diffract the light. However, I've been using the TICKR FIT both in and out of doors and I haven't had any particular issues with sweat affecting the reading; the arm band holds it nice and snug, which no doubt helps. Wahoo says you can wear it on the inside or outside of your arm; I prefer the outside. Two different sized straps are included, and both are adjustable for fit.

Armed and accurate

Wahoo's stated reason for producing an arm-mounted HRM is two-fold. Firstly, it says that it's the best in terms of accuracy, and secondly, that some athletes find a chest-mounted HRM uncomfortable. In the interests of not-really-science we asked the good people of Facebook and Twitter whether they found chest straps comfortable, and most of them seemed to be happy enough. However, there's certainly a minority out there (about 17% of our audience) for whom they don't work: some people just don't like them, and if you're a female athlete wearing a sports bra then the two often come into conflict.

And is it more accurate? Well, I've worn a lot of HRM straps over the years and I've never had cause to doubt their accuracy when they're working properly. A chest HRM is detecting the electrical signals from your heart, so assuming it's doing that correctly there shouldn't be much margin for error. I've found the TICKR to be accurate too. It's not inferior to a chest strap in that regard. But neither is it an improvement. They both work fine.


So, the TICKR FIT is on your forearm, and if you're hopping on the indoor trainer for a session, or heading outside for a run, or nipping off to the pool for a swim, then it's an easy thing to slip on and off. In my experience it stays put pretty well and is comfortable to wear. (Wahoo's youTube video shows it in action here.)

If you're off to Mallorca for a week of training in the sun you might be a bit loath to give yourself an even more idiosyncratic tan than you'd normally get. And if you're competing in a triathlon that involves a wetsuit, or you're riding in changeable conditions where you're pulling a jacket on and off, you're going to lose it in your sleeve sooner or later.

heart rate monitors

It's marginally less of a faff than putting on a chest band (which is rendered much more of a faff by the fact that you always forget until you've got all your kit on) but I can't see it taking over as the default position for competition, especially cycling. It's more prone to getting in the way, and you look a little bit more silly than you otherwise would.

In the end it's horses for courses here. I find the TICKR FIT pretty much perfect for indoor training: you can put it on in about two seconds, it works fine from the off without any faffing with position or licking of electrodes. If I was predominantly a swimmer or a runner I might also see the appeal of the design there. Where it doesn't work as well as a chest-mounted HRM is when you're out and about on the bike, taking your jacket on and off for the showers or working on your tan lines in the sun.

If you're riding outside, and want to measure your heart rate, and you really don't get on with chest straps for whatever reason, then at least here you have a different option that will no doubt be more comfortable.

It's a hard thing to score: there will be people out there who are thinking, 'At last! This is just what I needed!' I'm a bit more ambivalent, but overall it's a welcome option, and very easy to use.
