I bought a Swytch kit for by vintage Peugeot as it didn’t make sense to go thru the trouble of upgrading the gearing. Want to get a new bike with mordant gearing but picking are slim now days. I am forward thinking an will probably get a LeMond ebike when the time comes.

Just nice to have that extra help on the days when your legs fail you.
