Well thats extreme, and bordering on illegal  I wouldn't recommend that personally. What does work well is attaching a "sound" lock. Simply means that if the lock is cut/broken then it makes a 120 decibel noise. Many electrical shops use similar locks, but you can build your own for a couple of quid.
And a fun one is to hide your lock. Use a small high strength cable and loop it round the front or rear tyre. Hide the cable under leaves or rubbish. Confuses the fuck out of people when they can't get it away, and after 1 failed attempt people move on quickly.

Hey guys, I'm thinking about buying a carbon frame but as I can not afford a new one I have to look for used frame. I found one but I am not sure if it's worth taking the risk.

Last picture shows a scratch and is it likely to break?

I wouldn't buy a second hand carbon, especially one that's showing a fracture. Carbon ages poorly (though it has improved), and it's very efficient in terms of rigidity, but if it's partly broken, you'll lose the benefits.
Better go for a good aluminium or save money for later. |

Thanks for the advice, I currently have alu frame, I heard that one should not buy second hand carbon frames, but as the price is cheap ~100 euro, I just don't know if I should risk or no. Will have to think it over. Again thank you Aquarius.

Watts is the unit that quantifies power. So it's a power measurement.
There are different protocols to measure it, and it depends what kind of power the test intends to measure.
Typically it'll try to measure the slope in terms of Watts/heartbeat, your power at threshold and your maximal aerobic power, which are the most relevant figures for road cyclists (that is among figures that involve Watts).
The last version of tests I passed (10 odd years ago) consisted in increasing power by 1 Watt every two seconds. I had to pedal at a constant number of RPM throughout the test (100 RPM in my case or in most people's, you'll need that kind of figure when the power will become important anyway).
There was a computer screen in front of the test bike with 4 figures on it : heart beat frequency, power, number of RPM, and one I can't remind. You keep watching the number of RPM while you pedal.
There are other kind of effort tests where they'll measure CO2 and O2 in the air you exhale, but you asked about Watts tests, so...

thanks Aquarius
well I got what I asked for. I did something that was told to me was a watts test (basically keeping padeling at 100 RPM for 3 minutes) and I got +/- 250 watts.
personally not to bad considering that the guy giving the test underestimated me and put the bike at a too low gear

Three minutes is too short if that was the whole test, the body doesn't have time to adapt to the different metabolisms you're supposed to go through during a test.
Or maybe I misunderstood and the power increased by steps and the last one was 250 W that you sustained during 3 minutes ?
How much do you weigh, if I may ask ? |

I'm not sure about that myself but the guy did increase the gear overtime and I weigh 69 kilograms
also might be of importanse I did that test on a WattbikeSpoiler https://wattbike.com/uk/

Usually the figures are quite reliable on such bikes. Of course the road performances involve other factors, such as bike position, active recuperation, etc.
250/69 = 3,6 W/kg somewhere between threshold and maximal aerobic power.
I guess you don't do competitions ? |

I have a question about the Garmin Edge 800.
Is it possible to just ride around without using the GPS and that you can see the route you drove when you are back home? So that you can maybe save it and ride it later again.

You can upload the data to Strava if you mean that.

I have a similar GSP (also Garmin) and it records your current track as a gpx file. You can save it and set it as navigation track later, no problem. |

I'm going to get in on the "riding bikes around" thing that so many of you kids are doing. Of course, at a lower level. Like, the lowest possible level of exercising.
For starters: I just plotted out a route to begin training and get used to riding again, and my bike has twice as many gears as there are meters i need to climb

I live right on the coast and haven't ridden in like 2 months because I got sick of the constant high winds.
