I've just bought a Cube Town Sport Hybrid Pro for commuting, ten miles each way and 50/50 road and cycle path.
Standard chainring is 38T but I'm not using the lowest two gears at all; the steepest slope I encounter is a speed hump.
Before I start attacking a brand new bike with blunt instruments I thought I'd ask for advice.
I'm considering fitting a 42T chainring, a 10% change which should allow more use of the lower gears and slower pedalling rate.
What affect, if any, will this have on the motor, a Bosch Active Line Plus Gen 3? The speed sensor is on the rear wheel so I expect the 15mph cutoff won't change, but will I get
more assistance as the pedalling rate will be reduced? Does this risk overloading the motor?
Probably the first question I should ask is, is it worth it? I'll need new sprocket, chainguard and tools to remove the crank.
Will the difference even be noticeable?

but that doesn't have anything to do with the 42T )
