I was thinking, for those ebikes that are FWD, why haven't I seen people put their motor controllers and battery on the front rack? That would shorten the cables and a nice wooden box or girl's basket could hide it nicely and make it look good. Is it because of handling concerns? Too much weight to steer? What about using a steering stabilizer?
Also, would it be ok to use regular dual pivot or single pivot brakes for a e-bike?
Too many to list, some I built myself including the frame. I "do" ~ Human-Only-Pedal-Powered-Cycles, Human-Electric-Hybrid-Cycles, Human-IC-Hybrid-Cycles, and one Human-IC-Electric-3way-Hybrid-Cycle
Yes, with a normal front cargo basket that is attached to the fork and/or handle-bars steering would be affected by the extra weight, so a lot depends on how big (heavy) of a battery you have. There are some (mainly custom) front racks that attach or are permanently welded to the bikes frame and do not turn with the front wheel and handlebars and thus do not effect the steering or stability of the bike and actually make the bike more stable to ride with the cargo weight up front then a rear rack. That would work great.
As to using regular single or double pivot rim brakes on an e-bike. They don't have the stopping power of a good disk brake and since an e-bike tends to be heavier and/or faster and to be ridden more often for longer periods of time and longer distances then a regular pedal only bike having good brakes is more important then on a regular pedal only bike. Some of this can be alleviated by purchasing top of the line pads for conventional rim brakes to improve their stopping power which will make them almost as good as a cheap disk brake.
I've been wondering the same thing myself. I'm building my small Raleigh twenty folder in to an ebike right now and I'm at the stage where I decide where to orient my battery. A lot of kits (bionx, custom) have them batteries in the main triangle and the motors in the rear but the benefits of a front wheel drive for a small bike are just to great to pass.
If you can keep the weight of the battery up higher and closer to the steerer tube can you mitigate the forces on the steering?
I'm thinking about orienting the battery horizontally and using a bike truck style rack (super wide).
OP, where did you end up slapping dat chemical power reserve?
