Hi just my tuppence worth Dave,
I used to have a heinzmann 24v motor in a front wheel configuration, it was a standard 24v 250W model, and to me it did not have an amazing amount of torque when it came to hillclimbing.
For what you want your bike to do, the priority is a motor with high torque, so I would find the highest torque rear hub motor you can, and if that is a higher torque heinzmann then that is the best one to go for.
If it means converting your rear brake to a v-brake, you could get a local fabrication workshop to tig weld some v brake mounting bosses onto your frame. The bosses can be bought from a company like this:
Framebuilding Bicycles. Tubing, Parts, and Tools
or cut off an old frame. Bottom line is if you don't get a torquey enough motor you're going to be disappointed with your bike and the end result of the conversion.
