Also good news about the rear brake.
Have been talking to the Engineer who usually does our E-verts road worthyness and said as long as the rear brake can pull 0.7G during braking without locking the wheel it will pass. Doesnt have to old the bike still either.
so probly wont have to re engineer a disc brake onto the Crystalyte.

Got 2 new Crystalyte 5400 bare hubs, one 3 turn and one 4 turn off the Endless Sphere group buy.
The 4 turn is going in the posty bike and the 3 turn is being sold.
Actually had a buyer for $800 but he thinks he has found a supplier in Melbourne for about $500 so he has put the purchase on hold.
13.3kg with cast iron stator center.
already tried to pull a side cover off and it didnt budge, very tight.

My postie mate will be pleased to see this. If you're ever sued for copyright over the name you could try Going Postal. Hang on , that was a book and tv series. With reference to the frame strength, some larger posties carry a reduced bag load to comply with the compliance plate .
