There is something wrong with the DIY building of electric bicycles. It seems a simple thing to order a wheel, controller and a battery to go with it. But there are decisions to make about the wattage/voltage of the battery, how far you need to travel, etc. But I am not talking about that.
When Chris and I order a kit and open up a box with nice shiny parts we know those parts won’t be enough. Chris is handy with a lathe and grinder and 3mm steel plate and he needs to be. During the last build Chris had to make a couple of parts.
In his own words:
Pictures showing spacer bush machined to give clearance for chain on inside of rear forks. 1 machined in lathe and 2 in situ.
Anchor plate manufactured to prevent axle turning under the torque of acceleration. 1 plate made, 2 plate tested in situ and 3 painted and fitted.
