20in rinko reduced?

https://www.argos.co.uk/product/2728067?clickSR=slp:term:urban%20bike:1:411:1 I noticed this in the argos catalogue and wondered if it could be a sort of " rinko reduced "option due to short length. Unfortunately it has a folding stem so presumably not stiff enough/too failure prone for B...

Re: Hand sanitiser

As alcohol is miscible with water it can be extinguished with water... I always wonder why meths stove instructions don't point this out?

Don't you mean constant? The law doesn't forbid mark space (on/off) ratios other than 50% but that ratio must be fixed (hence seesense lamps' main feature is illegal in tthe UK).

Re: Brompton stem nutted bolt size (older style)

Thanks, having the same allen key headed bolt as modern Bromptons seemed superficially attractive , but I shall just look for a suitable lightweight spanner instead :)

Re: montaguebikes frames double tube vs large single

Thanks.
