Greetings - I've got a Bridgestone 27x1.25 inch road bike that I bought a decade or so back. Can bike of this wheel size be converted to an electric bike? Seems most everything is 26 inch or less these days.
Secondarily, if I were to buy a new bike (due to not being able to convert my 27-incher) with the intent of converting it to an e-bike, what metals are recommended for the frame? I've read that I need to avoid aluminum since it's too weak to handle the torque, right? Anything other metals? Do bikes with rear wheel motors handle the torque better?
