As I await my TMEC 200 this week I am pondering what it would take to change the speedometer cluster on the bike. I know it reads in KPH instead of MPH (even though it says mph on the dial). Anyone have any experience changing one out on a China bike? I don't want to really screw up the wiring on it (as I know it can be temperamental to mess with any wiring). Would love to hear opinions. My main goal is to have an accurate MPH reading on the dial.
Thanks!

I just bought the cheap ($20) phone bike mount from walmart and use my phone for a gps speedo.

I just do math calculations in my head--80 "MPH" is 50 MPH (5/8 x 80), 60 "MPH" is close to 56, so about 37 mph (5/8 x 56) or most streets. 70 "MPH" is bumped to 72 so (72 x 5/8) is 45 MPH. 65 "MPH" is really 40 MPH. It keeps me aware.

The speedometer operates with internal gears, and is driven by a mechanical cable from the front wheel. Therefore, you won't need to mess with any electrical wiring. ;) If you want to convert speeds from kph to mph, you have several options.
1) The easiest option is to multiply the kph reading by 0.6 to get the approximate mph reading. For example:
80 kph x 0.6 = 48 mph
70 kph x 0.6 = 42 mph
60 kph x 0.6 = 36 mph
Et cetera...
2) You could also remove the clear lens from the stock speedometer, put a custom, mph label on the face of the speedometer, and replace the lens.
3) You can buy a mechanical speedometer from eBay which is calibrated for you wheel size.
4) You can install a wired (not wireless) bicycle speedometer on your new bike.
5) You can install a Trail Tech, or Acewell digital speedometer designed for dirt bikes. I really like the Trail Tech Vapor speedometer which I installed on my Honda CRF250X. :)
