chrisebowen Posted July 25, 2003 Report Posted July 25, 2003 Which Speedo is best I have a Avoset altough it will set to the wheel size it will not go over 28. mph and dosn't like the wet, I have tried it against a Garmen Legend GPS the mph is right but the GPS gose over 28 mph can any boddy help Chris Quote
Greg Posted July 26, 2003 Report Posted July 26, 2003 i am going to try a s bike spedo from a company called PANORAM it has 3 screens and shows all your data (current speed, max speed, total distance ect... ect...) as it is a bike computer it should be able to cope with water and could odviously go over 30mph i and you can set your wheel size but it may only be able to take bike sized weels so it may only be used on domthing like a camelion iguana buggy Hope this helps Greg Quote
Coastguard Kites Posted July 26, 2003 Report Posted July 26, 2003 Hi Greg, I would agree that the Panoram is the best speedo option available (aside going the GPS route which is very costly). We have sold many Panorams and they can certainly be calibrated to standard buggy wheel sizes. http://www.coastguard-kites.com/assets/products/misc_panoram.jpg Click here for further info and prices.

Greg Posted July 26, 2003 Report Posted July 26, 2003 Hi Coastguard Kites I was wondering if you have any cameleon Pogona kite buggys in stock at the moment or would you have to order them in? sorry for the questions i willl phone you aswell in the not too distant future but also do the Pogonas give you much back support or is it like a libre V-Max?, if you do have some or could get one to me before the 10th of august then i will probably buy one from you, also a PANORAM computer in another month or so if you have one? Thanks Greg Quote
HD462 Posted July 26, 2003 Report Posted July 26, 2003 I have the Panoram on my motorbike, very good and certainly reads well past buggy speeds I got it cos my bike is an import so KMH is the main display on the speedo, and I dont like the conversion sticker you put on. They're a very good speedo, but not sure I'd use one in a buggy just for the fact they are expensive, and easily broken if you come out / flip it. You can also set them for two different vehicles, handy if you have different wheel sizes you switch between on your buggy ie: standard and bigfoots. So you don't need to re-calibrate it. For the Buggy I have the Atech computer from Index, £7.99, and nearly all the same functions as my Panoram, including pace, accelation / deceleration icons......and if you break it, it's cheap to replace. The Atech also goes down to very small wheel sizes, mine are only 10" wheels and it works fine. You just enter whatever figure you want, it's not a preset list you scroll through like some are. Quote
chrisebowen Posted July 26, 2003 Author Report Posted July 26, 2003 Thanks for all your info will look at both of them the GPS is to much at £200 + but a great gizmo. Thanks Chris Quote
Tom183 Posted July 26, 2003 Report Posted July 26, 2003 The Garmin "etrex" (base model) is under $100 - should be somewhere near £70 across the pond... Quote
caine Posted July 27, 2003 Report Posted July 27, 2003 Yep the panoram from coastguard is very good, have had mine fully submeresed buggying over a tidal outlet!! just watch out whyen fitting not to drill through the rim!!! Quote
redmonkey Posted July 27, 2003 Report Posted July 27, 2003 Marks and Sparks do a cordless bike speedo with a big screen on it for £20, better than trashing a £200 gps system. I'm going to try one as my last speedo kept on getting its cable trapped and cut Quote
Capt Slog Posted July 28, 2003 Report Posted July 28, 2003 Halfords cordless, £14.99, input wheel size in mm at 1mm intervals, easy to put on and works a treat. Very waterproof, went through a full hot wash/spin cycle in sons coat with no ill effects. Quote

Boldbunny Posted October 20, 2003 Report Posted October 20, 2003 I have recently bought a computer from Cateye. Same features as above ie 1mm increnments on the wheel size setting, max speed, distance and trip distance etc etc. It is a cordless model which made fitting a cinch and so far has worked A1. It was £30 so not the cheapest but lokks good, shiny silver and I really like it! Quote
Codename John Posted October 21, 2003 Report Posted October 21, 2003 Just been on halfords.com and they say there bike computers only go down to 18" Wheels. Which one have you got? is it: Halfords 9 Function Wire Free Cycle Computer Item code: 108423-0 £14.99 http://www.halfords.com/opd_product_details.aspid=16438&type=0&cat=102 Quote
Boldbunny Posted October 21, 2003 Report Posted October 21, 2003 The model in question is Cat Eye Cordless 7. cc-fr7cl is its cateye part #. I didnt get it from Halfords, just a cycle shop. It is adjustable down to 935 mm which is tiny. My standard Flexifiol buggy wheel measured out at about 1035mm (if i remember correctly) I marked a point on the wheel and ran it across the ground next to a tape measure, so I think I'm fairly accurate. If anybody knows how to come up with a better way of measuring the circumferece of a wheel then let us all know. Hope this helps CJ Quote
Mr J Posted October 21, 2003 Report Posted October 21, 2003 Circumference = pi * diameter of wheel. Diameter is the straight distance from one side to the other. Pi is a constant, 3.14159 (to 6 significant figures). So if your wheel is 100mm in diameter the circumference is. 100 * 3.14159 = 314.159mm Any questions class? Quote
dunx2022 Posted October 21, 2003 Report Posted October 21, 2003 I've just bought and fitted the £14.99 wireless speedo from halfords. It works on any practically any size wheel, you have to measure the circumference of the tyre and enter it. Was'nt to bad to fit, had to drill through wheel and find a longer bolt, had to tape computer to frame neck to keep it within range (2ft max!!!) It works fine!! Quote

You could just measure round tyre with softape measure:D Quote
Hoovooloo Posted October 21, 2003 Report Posted October 21, 2003 Originally posted by dunx2022 had to tape computer to frame neck to keep it within range (2ft max!!!) It works fine!! Got pretty much the same setup, but I chopped off the tail of the computer mount, shaved the back flat with a Stanley knife, then Araldited the mount onto the frame neck. Looks tidy! Quote

Looks tidy! Nice one, cool idea.... Will have to do the same with mine:D It will looks loads better than the red sparky's tape:eek: thats holding it on at the mo!!!!!!!!!!!!!!!!!!!! Quote
Hoovooloo Posted October 21, 2003 Report Posted October 21, 2003 The other thing you could do is drill and tap the frame to take the bolt. I tried it, but I broke the tap - DOH! Araldite was Plan B. Quote
dunx2022 Posted October 21, 2003 Report Posted October 21, 2003 I reckon you would need a serious tap, is'nt the frame made of stainless steel? that's 'kin hard stuff to drill and tap Maybe I will learn from your experience and go straight to your plan B Quote
Boldbunny Posted October 21, 2003 Report Posted October 21, 2003 Thanks for the maths lesson, I could have used that but you still need to measure a distance with a tape measure,, which is what i did. and I chose the circumference Quote
Codename John Posted October 22, 2003 Report Posted October 22, 2003 I find measuring the circumference by drawing a line on the ground the easiest. Plus you get less error in your measurement than by measuring the radius/diameter. But by introducing error you could get a faster reading than you should (perhaps that’s how some people get good max speeds Quote
Capt Slog Posted October 22, 2003 Report Posted October 22, 2003 I find measuring the circumference by drawing a line on the ground the easiest Thats what I did, sort of. I marked the wheel with chalk and placed the wheel over a chalk mark on the gound. Then with me sitting in the buggy I pushed along the ground untill I'd counted 5 revs of my chalk mark, then marked this on the ground. Devided the measured length by 5 to get wheel circumference. As it was part maths lesson for son Chip, we did the above a few times and took the average. Then we tried it with him in the buggy. Interestingly we got a differant result with his 4 stone weight to my 11.5. Quote
Codename John Posted October 22, 2003 Report Posted October 22, 2003 By using Capt Slog method the error is around 0.1% where as by using Mr J method the error is 1.5% This means that in 1Km the distance using the first method could be wrong by 1m where as using the second method this could be wrong by 15m. Over several hundred miles the inacuracy soon addeds up. But then if your gonna be that picky then buy a GPS Quote
