The bike
Regularly clean off dirt from the frame, wheels and box etc., using a damp cloth.
Regularly inspect for loose parts and get any tightened by your dealer.
Lubricate all visible moving parts, cables, adjusting screws, moving brake parts (NOT brake discs), chain, pedals, bell and lock regularly with bicycle oil. Bolts and nuts also like a few drops of oil.
Check that the chain has the right tension.

Tyres, tubes and wheels
Inspect for wear and cuts on the tyres.
Tyres are inflated to approx. 4 bar (60 psi).
Check for loose spokes.
Check wheel bearings for play.

Wipe the inside and outside with a damp cloth.
The box can be sealed with a thin film of linseed oil applied using a cloth.
Linseed oil can also be applied to the wooden bench.

Can be hand washed in lukewarm water (max 40 °).
Excessive washing weakens roof’s impermeability. Best is to wipe it lightly with a damp cloth or sponge.
