There are a lot, and in a world where you give up 2 cups of coffee house product to have a wireless cyclo, pretty cool.
A couple-three of my C&V’s just scream “No!” with any mounts, period.
I take a lot of cyclo’s off of used bikes, some work, some don’t. Older Sigmas are excellent, best I’ve seen.
As earlier mentioned, older GPS models work great and go from bike to bike. I picked up a used Edge 500 for $25 and a used Edge 25 for $10. I bought a used bike with wired functioning Flight Deck (which is a blast).
Currently, I’m a tweener, using Edge 1000 and various lights, radar at times. I’d prefer less, but my partner likes data.
Many of my riding friends are going the full Monty, with Cliq computers, front & rear lights, front and rear cameras. The whole setup looks right at home on their 2022 high-tech bikes, and integrates with their electronic shifting. They are not C&V in any way, shape or form, but it’s nifty.
speedevil suggested I try an old cell phone, sans Simm card, using Ride With GPS. It was free, an older Samsung. The app works great, battery life is 14 hours, and I can load routes, save routes, etc. I can’t call anyone, and they can’t call me, but that’s exactly why I ride. In effect, it is a very cheap, very capable cyclo, for non bio data. It just looks like a cell phone.
