Archon Speed Bluetooth Wireless Bike Meter

I've only ever used the cheap traditional devices on my bike but I thought I'd join the smart phones and connected devices age and buy this considering it's not expensive at all. It seems very well made as well and looks like it should be quite durable. It provides all the data one could wish for and the app is simple enough for anyone to understand. It's a good tool to have as I like to go out on long cycle runs, taking different routes and investigating new trails, it gives me all the info I need to evaluate which route is longer or more taxing etc. My only concern is the way it's attached to the bike doesn't make it very convenient to change the battery (or to quickly remove to prevent theft if the bike is left unattended etc). The product and packaging is of high quality and attractive, so much so it gives confidence in this brand that I'd never heard of previously and I'm tempted to try their fitness watch as I do a lot of jogging also.

Nice to look at but useless, bluetooth continually drops out. Picks up speed with no cadence or cadence with no speed. Finally dropped off on the road. Useless.

I actually bought this because it is white, which looks better on my bike as it is white too! Hardly see that it is there. So far so good, has stayed in place, and seems to be accurate. I use it with Komoot, a routing app for cycling and walking on an iPhone SE (old version like 6). Was easy to fit, set up and use, no idea on battery life yet as only used twice a week (30-50 miles each) and not been fitted for that long! Tried the app that it is built for, it works ok but doesn't do routing, only performance. The black gubbins is the wired sensors for my old computer, it will disappear soon as nearly everytime I reset the trip it resets everything, so I have to reinput wheel data etc! No such problems with the new one. Take care, stay safe, keep well!

Well, got a turbo trainer and wanted an alternative to turn it into a kind of a smart trainer. Been looking on amazon, found this model for an extremely great price: cadence and speed sensor for £8. Arrived quickly, clear instructions, quality item. SO far so good... But... it's very sensitive in a way that every time I have to fine adjust the sensors to make it work. This is quite annoying. ALso the provided app is weird, as it needs lots of permission... for instance messages, phonebook, and so on. Why??? After all it works fine, it's 1/3 the price of the same sensors, and it's connecting only via Bluetooth. Because of these small annoying things i'm giving 3 stars instead of 5.

Worked fine for about a month, but needed constant adjustment to keep it working, then just stopped reporting speed or cadence despite Bluetooth reporting it was on and connected.

Wouldn’t connect to phone

Bought these to go on my sons bike to ride zwift. I’ve been using wahoo for 5 years and have got annoyed with the need to be very precise with the placement, maybe it’s just old! Anyway, thought I’d tried this to keep cost down and hey presto, simple, easy and worked first time, no hassle. Slight downside is that as you use cable ties to attach it, it’s then permanently on if you go out in the trails so it can get dirty. The wahoo has heavy rubber which is easy to clip on/ off (but is 4x the price. We run zwift off iPad.

Worked for about 5 minutes. Adjustment has to be super precise. Gave up trying with this.
