An accurate, good speedometer for MBs?

    I'm in the market for an accurate digital speedometer for my bike. I currently have a Sun Ding digital speedometer I got online for $15 on my motorized MTB but it seems to be inaccurate or just defective. I hit my top speed which should be 25 mph easily but it goes to 20 then back to 9 then back to 20. Seems to have trouble making heads or tails at higher speeds.

    There's also a rattling sound coming from the inside of it which might be why its having trouble reading my true speeds. So anyone know of a good digital speedometer for a motorized bike preferably with a back light & a mph setting & good for higher speeds? I would probably be willing to spend $30 on a decent one.

    I looked at all those. I ended up using my smart phone. Bought a mount and installed a free speedometer app. I also mounted a Beats pill so I run pandora on my phone and have my speedometer in big bold numbers. It holds top speed, average, miles logged and a bunch other stuff I have no clue how to use. Not a tech person over here. Lol
    It's also pretty cool as if someone calls me, I can hit a button and talk to them through the Beats pill while I'm still riding. It all looks pretty cool mounted on the bars as well.

    dont place them ANYWHERE near the ignition system is a good one... use a resistor plug, cap and silicon resistive wire, all helps cut down on EMI

    I am not sure if anyone else is having this problem, but with the speedometers that use magnets, it doesn't seem to work when they get wet...

  8. Haha yeah man that's what I'm doing. I'm pretty much over the crappy spedos they have online. Plus you get to listen to music lol in my opinion I think it's the way to go

    Plus it's a great tuning device. It holds max speed etc.... So I can do a run, check speed, reset, make a change, run again, check speed.

    I have one I got off eBay for around $20. It lasted about 32 miles and the odometer still works but the speedometer does not. It is not very accurate either. Trying to work things out something with the seller.

    Being my phone does not have a camera using a apt for a phone is not an option for I.

    I use this one and love it. It's accurate and has an odometer. Minor problems are a kind of short cable and it will offset your front wheel a tad due to the piece that is mounted on your front axle between the fork and hub. This piece is what spins the cable to get your revolutions. I tried a digital one before this and it didn't work at all. Check out the link. It's cheap and works great.

    I have one like that. It lasted me 32miles before the speedometer broke but ondomotor works. I have a 27.5 bike I put it on and the listing said for 27.5 and it is WAY off. I wish you better the luck then I had. They are made out of just about all plastic not like the good old days when I was young.

    Well my luck ran out today. Speedo won't go above 20mph and I can tell I'm runnin about 30. It just kinda wiggles around after 15mph now. It lasted me 79 miles but its useless now. I recant my recent submission in which I praised this particular analog speedometer. I can't say I would recommend it now lol.
