Large speedometers for a 20" wheel in a tricycle
Hi. I will need a speedometer that is compatible with my 20" front wheel. Sure, digital is great, but size matters and I'm having trouble finding a cyclocomputer in Amazon.com that is over 4" in size, so it seems I'll need to go analog, so are there any speedometers that are large enough for me to read? I found this, but I'm unsure of the dimensions so I'm wondering if there any speedometers (analog or digital) that are large/oversized (4"+ for analog, 5"+ for digital) that are very easy to read? It seems my only choice is to get an analog speedometer.
Or is there anything that I can make the speedometer be closer for me to read while not interfering with my field of view in the road?
