What Speedometer Should I Use For A Bike That Has 10Inch Tyres?
If, by pocket bike, you mean a cycle, then you want a cycle computer that allows you to set the wheel size (Assuming that you are using the type that has a magnet in the spokes). Failing that, look at a GPS system. You can download a free version for your telephone. I use sports tracker. Failing that, try an entry level GPS unit. Garmin do one for about £60. Now, if your pocket bike has an engine, then you will be able to get a speedo anywhere. The problem is whether your bike is able to mount it. Typically, speedos will Connect, via rotating cable, to a slot near your front wheel hub. If your pocket rocket doesn’t have a connection for a speedo, you need to get one built. The speedo itself is easy. Just go to M&P or Demon Tweeks and order online. You should be able to mount this on your bike by drilling and cutting a flat piece of aluminium, to act as a dashboard, and then mounting this to your bars. The problem is going to be the wheel connection for your cable. Buy a copy of Street
