I have an Allant 9.9 that lists the chain ring as a prowheel on the Trek specs for the bike. The Prowheel is not even a Bosch compatible crank set. In fact the front chainring is the Diamante which is specifically designed to be compatible with Bosch gen 4 motors. Look at your bike and look at the Diamante and Prowheel and then tell us which one you have on your bike.
Diamante Bosch specific chainring
Compatible with Bosch Gen 4
With spider and bash guard
the front ring has nothing to do with how many speeds a drive train has unless it is more than a 1x It is the cog count in the rear that determines the # of speeds on a 1x drive train. On a 2x with two front chainrings the gear count is the number in back times the number in front. THEY DO offer the Diamante in different # of teeth, currently in stock are 40 and 46 teeth. The bcd does not really matter either as long as the front cog fits the front spider. It is the front spider mount direct drive spline that has to match up to the motor drive side as well as the offset so that the chainline is correct.
