The people at Cyclemeter (hardcore iPhone bike comp app) told me when I was asking about some data inaccuracies - caused by sensor placement - that GPS isn't very accurate when it comes to measuring speed. That's why so many bike computers, including Cyclemeter, uses sensor/magnet data. In the case of Cyclemeter, the app takes the reading from the sensor over and above the GPS, even though that is available, for improved accuracy. You are so right there mate! Hence the reason I got the Panobike Speed/Cadence sensor.

The Garmin GM10 (or something) sensor does cadence & speed in one. It's ANT+ but not sure it it works with other brand units. I bought the June issue of Stuff magazine from one of those market stalls that sell out of date mags for a quid, in it they reviewed the Garmin 810, bryton rider 50 and an iPhone mounted. They got 5, 4 and 4 stars respectively. The bryton was criticised for not being great at navigating on the fly, but great if you preload your route via gpx. It can't search for postcodes or building names it says and that's the biggest inconvenience, but you can get around it by searching for junctions instead. Its the GCS10 speed/cadence sensor and it should work with any ANT+ GPS computer.

In the case of Cyclemeter, the app takes the reading from the sensor over and above the GPS, even though that is available, for improved accuracy. You and they are not wrong. The GPS chips in bike computers and more so mobile phones all have a trade off when designed; Accuracy vs position lock time vs battery. The fully powered gps modules with antennas used for accuracy over the other two factors I'm sure are spot on. I assume with cycling computers (and mobiles for sure), accuracy is 3rd to battery usage and position lock time for obvious reasons. I would think magnet on the wheel would be pretty accurate, if the manufactures have worked out tyre sizes correctly. Remember deviations in tyre sizes, and tyre wear will put your readings off slightly. This is more of a factor with cars as tyre wear is more evident as is the fact, all manufactures over state your speed to help you stay within speed limits. This is a very good point. The faster you go the more polls to the satellite the GPS will make - hence battery usage will increase with speed. This is a major drain on mobiles has they have a greater demand for battery usage then single purpose bike GPS devices.

I've posted this as well and it is really a cracking deal but some mixed reviews. As O says the surprise me feature is the best thing on the bike reading the reviews. I'd still prefer a Garmin over anything else right now but can't justify the cost. By the way for anyone wanting turn-by-turn directions, from what I've tried on fellow riders 800, it isn't that straightforward. You need to create a route with something like RideWithGPS, that will create cue sheets to give you that ability. Also you'll need maps downloading (free ones are available, charge for Garmin), so out of the box, no such as turn by turn. Thanks for this. But I assume that you get maps and turn by turn on the Mio & Bryton? I agree with you, that the Garmin products are the best, but at the price of the Mio & Bryton, we are not really comparing apples with apples. My friends have the lower cost Garmins (200 & 500) and the navigation is quite poor. They have a breadcrumb feature that stops working when they are still. I am tempted to buy the MIO at this price. You can't compare the lower Garmin without navigation with the Mio 305 and Bryton with navigation. Price wise yes. Bear in mind the 500/510 models are very good devices and offer features that the Mio 305 and Bryton don have so you see feature set isn't the right way to look at it. It's what you want to do with the device you should be concentrating on .

Hence the reason I got the Panobike Speed/Cadence sensor. How are you going with the Panobike sensor Whitey? Was paired with Cyclemeter, now Garmin 500 via ANT+, is that right? I started a thread on sensor placement in the tech section as the fat chainstay on my T3 was causing a problem having both the speed magnet and cadence magnet in range of the sensor. Had a proper go at sorting it last night and based on a comparison between Strava and Cyclemeter recordings from this morning's ride it's not far off. Still too much discrepancy in some areas but nearly there. Have uploaded my raw ride data to CM who will ping me back an analysis this evening I should think. PS somehow accidentally selected my activity in CM this morning as 'Nordic walking'! Lols! Fortunately you can edit this afterwards...

Actually my Panobike speed/cadence can't work with the Garmin computers because they are using the newer bluetooth standard - Bluetooth Smart, whereas Garmin in their infinite wisdom have stuck with the older standard - idiots I say, but then that's me the layman talking. Hence Panobike sensors will not work with anything apart from Smartphones it seems.

Well the unit has arrived and I'm impressed with what I've played with so far, which admittedly isn't much (my resting HR is 55bpm apparently). It seems to pick up my C14+ sensor without a problem.
True test will be tonight where I intend to try out everything it has to offer. Already loaded a well known route to test navigation.
@robothamster from what I can see the 'on the fly' navigation is a bit fiddly. Not by postcode but by town name, street name and number. Good enough for me.

Good enough for me. Good to know you now have it. I have seen seen it necessary to try out the heart sensor. Just haven't seen the need for it. I should note that I was expecting your C14+ sensors to work as they are ANT+ compatible devices. Hope you don't get lost tonight!

I think the HRM is going to be very useful for taking my training up a notch but at the moment it is just a bit of a novelty.

What to do with it and what do the numbers mean? Just baffles me at the moment hence its still in the box.

I was doing HIIT training a while back and was riding really well, i then went on holiday etc and lost a lot of fitness. At the min i'm just back out riding again with the odd longer ride thrown in but intend to start HIIT again soon. Also good for winter on on the Turbo. It's well worth working out your HR zones and using them in training.

It's what you want to do with the device you should be concentrating on . I would like a device that did basic tracking (which they all do), but also turn by turn navigation, off-line route planning and also with upload etc to strava. I would like HRM, but not too bothered about cadence monitor really as I think that this is one part of my riding that I have got nailed (unless the hill is really steep). I keep a high cadence at all times and usually higher than the people I ride with and they can struggle in the hills. I have looked around at devices, but at Β£140 the MIO with HRM & Cadence monitor seems to be a bargain.
