16kg? Jesus. It's an hgv!
For grime removal I use a radiator brush, bought cheap, with a long handle, and some petrol or paraffin. With a drop of oil if you wish. Brush it on, the grime dissolves. Done. Polish it with a rag when done.
Dear Steve,
I have paraffin here, and used a little bit to attempt a first cleaning effort on a tiny patch near the steering tube, where the grim is rather thick!
Underneath is lovely original enamel.
It will clean up very nicely.
I rode it round the block earlier, and it is a charmer in a sort of cruiser way like a Rover P4 [60, 75, 90] from the early fifties! Stable safe-handling bike with no aspiration to exceed 15 mph, which is fine as that is the legal limit for electric assist.
The weight is battleship style, but adding more for electrification will not spoil what is already a heavy-weight. I guess that it will end up on Schwalbe Marathons, as rolling-resistance will hardly be a significant issue.
The damage to the enamel is inevitable on a fifty year old bike, but nothing that spoils the bike, or has deteriorated to any serious degree. It does not need repainting. Apart from the fact that it has subtle light blue pin-strips on the mudguards, and gold ones painted on the chain-guard and frame, it is clear that this is real paint not decals, and done by hand. That would be hard to replicate at any kind of expense I could afford.
Once one spends silly money on a paint-job, one fears to use the bike as a daily, and this one will definitely be a very nice daily.
As a survivor, I intend to keep it as original as possible, and any electrification work will be totally reversible. This rules out a rear motor as the Sturmey Archer three speed hub is intrinsic to the concept of the bike's concept.
But the forks were certainly made by engineers who worked in the tradition that produced "HMS Hood" so there is no doubting that in normal use it will handle 250 Watts of motor without folding!
I am very pleased to rescue this old classic from living outside till it becomes another wreck, ready for landfill.
Best wishes from George
