My 'City is pushing 2000 miles and the chain looks good. Not getting any special attention either. Why do you believe you need new chains?
Mine look OK too, no skipping or anything like that but when I measured them they were surprisingly stretched. It’s surprise me I figure better safe than sorry, chains are cheap and easy.Haven't measured the chain, though my mid-drive buddies are telling me to, but 1500 miles and no problems. I have completely cleaned the chain twice and use tri-lube.

More then .75How much did the chains stretch relative to what a regular road or mountain bike would stretch with that mileage?
Checking the chains on my mini and my rover, both have a little bit over 1000 miles each, and they need new chains, just wondering how many miles are people getting out of their chains on the rad bikes thanks
That could be the chain popping on the back sprockets I don’t know, go to park tool on YouTube they can explain it better than I can. As the chain Get stretched you don’t even notice ,After I put on the new chain shifts are crisp and a lot less chain noiseCan you tell me what symptoms one might experience, if the chain has gone south?
I am experiencing a loud metallic "pop" when I put a medium amount of downward pressure on a pedal, especially the left pedal, for some reason. I replaced the original pedals, as one had gone bad and the "pop" seems to be more frequent. The noise seems to be coming somewhere near the front crank area. I cant make it happen on the bike stand, due to the amount of downward pressure needed. I have nearly 1400 miles on a 2019 Rad Rover, with some hard, desert riding on it. Chain has been cleaned and lubed twice, since acquiring.
To measure a chain, must it be removed from the bike?
I have tightened all hex head bolts on the front crank, as well as the rear axle nuts. None were loose. Derailleur adjusted, as are the brakes. No out of roundness observed in the rear wheel.
OK, I dont have the slick Park Tool chain measurer, but the layman's method they describe, using a ruler, shows my chain is more than 1/16" stretched. I will be changing it out.
1/16 inch on one pair of links, or the entire chain length? The other poster mentioned 3/4 inch, that's still not a lot on a 50 inch ?? chain
This all seems a bit overkill to me and will be a bit wasteful. (save the earth and all that) The tolerances are not that tight on this stuff. You could be replacing the chain once a month. The Chinese manufactures will like you though.
The Rad electric motor drives the rear wheel directly so cannot stretch the chain, only pedal effort can do that. So as regards the derailleur, gearset, shifter, cables etc its just a normal bike. You generally don't wear our regular bike chains in a 1000 miles.
Mid-drives will break chains more often because the combined motor and pedal torque.
I do not know if chain stretching at 1000 miles is good or bad. I peddle it most of the time in PAS 2 or 3 , I don’t think it’s a bad deal to buy a nine dollar chain every 1000 miles to get more out of the free wheel and sprocket in the long run.1/16 inch on one pair of links, or the entire chain length?

Over 1/16" over the total length of the chain. More than the acceptable level of stretch, according to Park Tool. Who, I dont believe, are in the business of selling chains.
A 68 lb bike with a 200 lb guy, putting his all into the pedals at Pedal Assist 5, going up steep rocky slopes (and still not making it, due to the incline), is not something "regular bike chains" are asked to do, I dont believe.
The B-tension adjustment on a Shimano compensates for this.
It does not. Here's Calvin from Park Tool explaining the Shimano derailleur adjustments.
There is no adjustment to compensate for chain stretch. When your chain stretches too much, you should replace it.
Normally, measurements of chain stretch are done per 12" of length. Again, I recommend reading this thread to more information.
