I didn't want to state how i fixed my bikes front missing bearings until i tested it, if it didn't work i would feel responsible for a someone coping it and having an accident.
Ok here it is, the swivel chair i'm sitting on suffered a failure 8 months ago, a piece of plastic with 2 bearings fell out, i kept them, then doing my 6 month tear down, cleaning and re-greasing of the cheap hubs on the bike i noticed i was 2 bearings short of a full hub :) I remembered the stainless steel bearings i put away from my chair, measured them with a digital caliper, perfect 3/16 match. Installed them, adjusted them by feel and the front wheel is smoother than factory. I put 2 kms on it Saturday, 30 kms Sunday (21 miles) and 4 kms today in freezing rain, no issues.
Just as a comment bearings are made in standard sizes, being metric or standard. To save money manufactures design their products around these standards, your house probably contains enough bearings to rebuild your bike 10 times over.
After tearing my cheap wal-mart bikes hubs apart (easy) i found the races and bearings where in perfect condition after more brooks than i can count, bogs, salt and sand for 2 years, incredible! REGULAR MAINTENANCE!
As an afterthought in the early 80's i wanted a $75 7 bearing fishing reel but could only afford the $25 2 bearing model, side by side they looked the same. Bought the $25 model then dissembled it, went to the local industrial bearing place, had the cheap plastic inserts measured and bought 5 steel bearings to replace the plastic at $2 each. For $35 i had the 7 bearing reel i wanted.

Glad it worked for you. But to be honest, jerry-rigging wheel bearings on an ebike seems like the mechanical equivalent of self dentistry. Super glue and aluminum foil could probably be used to fill a cavity. For a while. No guarantees.

I understand your comment, spit and bubble gum don't always work especially if your not mechanically inclined but i had an idea this was a good call. So far beautiful, another 20 miles today Chuck
 
LOL. I thought you packed in grease and packing string.
LOL not a bad idea but travelling along the longest highway in the world (trans Canada highway) is scary at best, not going to put my life on the line for a piece of string, going with computer chair bearings :)

There is no guarantee in anything in life. I'm not a machinist, but... Chair balls might have been made of softer steel or a rougher finishing than a bike bearing (note that I'm saying "bike" without E, since a wheel is a wheel). Though I doubt the difference is that significant. More likely that chair balls are less corrosion-resistant. Keep it lubricated.
