The chainring on my electric bike has 53 teeth I think, and there would be plenty of room for 2 more chainrings. On my manual bike that has a 42T chainring, there wouldn't be room for the sensor that's on the bottom bracket and the plastic ring with embedded magnets that's on the crank axle/spindle. Some electric bikes have the pedal assist sensor on a wheel I think. There would be room for that kind of sensor on my manual bike

I know it does. Somehow the first and third posts of the thread got combined in my head and made me come up with the idea that 1 chainring bikes were made for Europe.
