Other question for Homage users.
4. If you configure the Homage with the Higher torque Bosch CX, is the assist artificially limited to 20mph or also 28mph?
Yes, the CX motor assistance is limited to 20mph.
But No, the Performance Line Speed motor does not have lower torque output.
The MAIN difference between the two motors is the availability of adaptive power modes in the CX motor versus flat rate support percentages in all modes on the Speed motor.
I happen to LOVE the adaptive eMTB mode in my CX equipped Homage!!!
And I am hoping to get the adaptive Tour+ mode activated on my unit as well, if my LBS will do that for me.
(In theory, the Tour+ mode is supposed to only be activated on chain-driven bikes, which does not make any sense since the higher dynamic assist eMTB mode is able to be used on belt drive bikes.)
The adaptive power modes automatically adjusts the percentage of motor boost based upon your input torque, cadence, speed, and several other factors; calculating and adjusting 1,000 times per second.
The result is a very natural pedaling experience which feels very much like pedaling a non-assisted bicycle, just with bionic legs!
I have bad knees, and on my previous e-bike was constantly having to change the power mode depending upon changes to the grade/wind/etc. to keep from hurting my knees while riding.
The Bosch CX eMTB mode basically eliminated the need to ever think about my power assist mode except for occasionally cranking it up to Turbo for long & steep climbs.
I don't often miss the extra 8mph of possible assistance speed.
I usually maintain a level ground pace of 14-15mph, which is just fine for me since I am riding for recreation, mental health, and fitness.
When I do start topping out the speed limit, I just remind myself to slow down 1-2mph and enjoy being alive.
And when going down the hills in my area the bike will easily coast to well over 30mph, which is above the assistance limit of the higher speed unit.
Below are a couple of links to the Bosch E-Bike webpage explaining the adaptive modes, and a chart of the differences between the Speed and CX motors.
As always, YMMV.
