Need A Reliable MECHANICAL Speedomenter?
I recently motorized a mountain bike and it is great. I bet I can top 40MPH!! Only problem is, I have no way of knowing for sure how fast I'm actually going. I could buy a digital speedo for like $10-20 but I want the look of having a speed gauge on my bike, plus it's a little harder to read a digital speedo at a quick glance when the screen is like 2 inches long and wide! I saw this mechanical speedo on ebay for $10-20, but some reviews of it on other sites says it breaks really easily, or as soon as it hits 30 MPH it goes crazy. Does anyone know where I can get a reliable mechanical (analog) speedometer?
