The Electrosport units have been discussed elsewhere here so I took the plunge and ordered one of the 2700's without the fuel gauge. Phone ordering was easy and shipping was quick.
This seems to basically be a lower end electronic device, wiring is small and delicate. Instructions are limited and the English translation isn't clear. This is the kit not including the wiring, spark plug for size reference:
The speedo uses a fixed plastic sensor and a rotating magnet, shaped much like a bolt. I couldn't find a convenient place to mount either so I ended up making a bracket for the sensor and drilling a hole through the brake disc carrier.
I was initially a little disappointed with the small face size but now like how it's out of the way and unobtrusive. Another custom bracket to mount the unit. The small arm they provide with it wasn't long enough to mount anywhere useful.
From the front you don't even really notice it.
As for the function, rpm's are displayed in a digital bar graph and can be shown numerically across the bottom. It only displays rpm's in increments of 100's.
When the bike is turned on, the default display however is the tripmeter (1 of 2), so you have cycle through the mode button 4-5 clicks to get rpm's displayed numerically.
I plan to test the speedo against my GPS unit at some point but that's not the most precise comparison. It is reading double at times, one second it's 40mph, then it's 80. Most of the time it's stable and appears to be fairly accurate. The instructions say the sensor/magnet distance should be a maximum of 8mm, I have it at about 5mm.
I hooked up the left/right signals, neutral and high beam indicators and hooked the oil switch in to the unit's hazard light.
Also, the backlight is blue. This isn't an issue during the day but at night I'm bad with blue so it's almost unreadable to me. Overall, since it barely costs more than a good bicycle computer and has the tach capability plus warning lights, it's probably not a bad deal. You get what you pay for.
