Well, perhaps you might like to post the URL to that, instead of the urlto
a vested interest, akaan importer.

Otherwise we are going to realise that you are just a scumbag sock puppet
for zbox.

Nope, that's fine, can work that out.

What I initially want to do is power assist the front pair of wheels on a
trike, so all I'll need to worry about, for legal reasons, is sensing
that the chainwheel is being pedalled. Hmm. sensor in BB would be most
protected.

When it comes to assisting the rear wheel drive, I'm wondering if it isn't
easier to look at driving the rear wheel/hub by two chains. I have a old
double sided fixed(?) rear wheel hanging from the rafters in the
garage^h^h^h^h^h^hworkshop, which set me wondering. Either use the
7/6/5th cog on the cluster/cassete or braze an adapter for a cassette
cog on the other side. You'd probably need high flange hubs so you can
still change the spokes.

repairing the Kenwood mixer(mech fan dropped off motor spindle, rotor
