Unless you have different tyres ... That setting will make you think you are going faster than you really are (52.5km/h instead of 50km/h)
With tyre on ground & Kart fully laden, make a mark (tyre & ground), roll forward one revolution, make another mark, measure between marks (in mm's)
... Measurement should be around 970mm .

Yeah thats the one many of us have, and it will need to be rewired (extended).

Subject: RE: [blokart] Re: Speedometer for blokartHi Denis
I picked up a 'Smart' brand computer from DSE in Botany yesterday – it was the only brand they had that I could see. Also $36, it's in a lime green box and the only place the brand appears is on the actual unit visible though the window on the front of the box. The Box just says "3 in 1 Cycle Computer
– model F9116".
They had about 3 or 4 left yesterday afternoon.According to the instructions it is fully adjustable for wheel circumference (in mm increments) from 2999mm down to 10mm! Beats me how they could fit the magnet onto a wheel that small though. Have yet to try fitting it to the Kart. It will need some form of extension as the wire from sensor to head unit is only 800mm long.
Has km/h or MPH speeds – current speed, average speed, max speed (0.0 to 199 9 km/h, or 0 to 110 mph), trip
time, 24hr clock, alarm clock, trip distance, max speed alarm (fully adjustable up to 199.9 km/h – anyone game to try THAT?!?), trip time alarm (in case you have an apointment to get back
for!) and trip distance alarm.Instructions also specify it is a most advanced model, and they believe it will become an inseperable friend!

Are yousure the brand was 'Smart'
'DSE only have the 'Liam' model ($36) but I want to make sure I get a replacement that can do the job. There are no useful specs on it.Cheers

Your adaption sounds great. You should take some pics and post it on the Smartgroup to show others.
I knew the limitation of the new Cateye's, so avoided buying that type.
The Smart brand speedo has given me no trouble at all, and I have reached and recorded speeds of around 65kph. (Very hard to control at that speed!)

Subject: Speedometer for blokartHi Dave,
Interested in your speedo adaptation, as I have been experimenting quite a bit as well.
I am using a 10-year old 'Cateye Mitty 100' but it can't process the information past 20 pulses/sec which is about 53 km/h.
How fast can the Smart brand' register?
(I made up a reed switch and slid it up inside the front fork, then drilled a hole up directly into the steering column – so there is no visible wiring or sensors at all. It's a very reliable arrangement since it can't get knocked or wet.)
Regards
Denis

Subject: Re: [blokart] Cordless speedometer for blokartFor value for money, I think the best bike computer you can get, which will calibrate for a Blokart wheel is the "Smart" brand available from Dick Smith electronics for $35 ish. I think that this is the type that the Blokart guys have modified.
I know of many people that have used this speedo, and if you are not afraid of doing a little re-wiring yourself then they work perfectly. I have tested the accuracy against my Garmin GPS unit, and it agreed almost perfectly. The key is to enter the correct circumference of your tyre at the laden pressure
There is nothing wrong with the accuracy of the GPS's these days if all you want is a speed reading.
I have wired my bike computer through the handlebar piece, so it is effectively 'cordless'. You just have to remember to disconnect it when you pull the handlebar out. Some people have done much better jobs than I have, and may have their advice also.
Keep in mind that this is only MY opinion, but hope this helps.
Dave
