Any recommendations for a trip computer? Are the ones that were in Lidl any good or would i be better off sourcing one from a bike shop?
Also do wireless computers work ok or are they troublesome? I had one before on a mountain bike and it was a bit hit and miss - maybe they have improved since...
I've got one of these Sigma BC1606L wirelass computers, together with a wireless cadence sensor. It's really easy to fit and very reliable with no problems with the sensors or computer even in extremly heavy rain. You get what you pay for and are better investing in something that will last for years. Cheap computers are a false economy as you'll likely have to upgrade at some point.
edited to add: I got mine in their sale (January) which was 25% cheaper than now
I've never used the Lidl ones but I recall a few people on Boards saying they bought one so maybe one may come out of the woodwork.
As for wireless, I've got a Polar CS100 and I've no complaints.
Talking about Bike computers, anyone know how to programme the darned things? I have a TECHWELL one with a wire going down the forks (magnet driven) but since buying it several years ago I have lost the instructions & I dont know what Four Digit Code to input (wheel size)?
I have an old Racer (27x1 1/4) wheel size inc tyres but how does that translate into the four digit code? (c 0000)
I have tried several suggestions, but the distances do not correspond with what the Cars odometer says > I went for a spin the other day and the Bike said I had covered 7.75 Km (the same trip in the car said 8 Km)!
Any ideas anybody?
Car odometers are usually inaccurate and in my experience usually overstate.
I'd get your hands on a GPS unit and work from that.
I'm not sure, but the four digit code might be the circumference in millimeters. I entered 2124 into mine and it seems reasonably accurate (I think). I wouldn't use a car to calibrate a cyclo computer; they're too inaccurate. Use a known distance like a running track.
That code sounds interesting Slow Coach, I have been around the c2100 > c2200 mark, and I am getting closer to "Car Kilometres" not that it matters now, seeing as somebody has suggested that most cars do not record distances correctly in the first place
I shall give your suggestion a try & post the result here tomorrow.
Been a while since I set mine up, but it's mm alright and as far as I know it's tyre size that's measured. According to this reference chart, it should be 2199
I use a Mavic Wintech ES with cadence and love it as the saying goes does exactly what it says on the tin
I would certainly hope it does. So, what does it say on the tin?
I bet it says "Mavic Wintech ES with cadence".
I have finally discovered the magic code for my TECHWELL Bicycle computer & it is c2265, this now correspondes precisely to the Car odometer over a distance of eight Kilometres (round trip)!
Dunno why the code is c2265 because it seems to make no sense, but it works perfectly on my (27 x 1 1/4) inch tyres even though one rotation = c2118.
Baffled, but finally Happy (unless the car is wrong) .....................
The car probably is wrong, if one tyre rotation is 2118 that is what you should be putting in. There are reports of motorsport people wiring up bike computers for more accurate readings.
As to type, I have used two Cateye Mity 3s, the older for around a decade in all conditions and it is still going strong. This is a cheap (c. €25) cyclocomputer, basic but very reliable.
Personally I wouldn't bother with wireless, you are paying more and have extra components and batteries for very little benefit. Computers are very easy to wire neatly to the front wheel, wrapped around the brake cable and then the fork. Where wireless does have a benefit is if you want cadence or to use a turbo trainer and so want the magnet on the back wheel. (I do have a GPS with wireless cadence and heart rate.)
I did buy a Lidl one once but for whatever reason it would never turn on.
Best way by far is to get yourself down to an athletics track - UCD is very handy for this - and calibrate your bike there.
So if my car speedo is that far out, does that mean that most second hand cars have odometres that are out by thousands of Kilometres, or maybe even (tens of thousands)? surely the AA and the various road authorities in Europe would be onto this scam!
Pretty scary I say.
P.S. when I measure the diameter of the wheels (inc fully inflated tyres) they measure as 71cm instead of the 70cm that you would expect from a 27" tyre ..........................
