Thought I'd change the matted oily chain on my Raleigh Leeds- panasonic motor and hub gear.
What would you think- well i thought that too -a single speed 'BMX" chain should be fine. So had one in the shed and then find it's not as long as the one I've just removed - by about 12 links. So, luckily having kept excess links aside in the past i made up an equivalently long one only to find the new chain's 1/8th" width won't go through the jockey wheel/ derailleur [transverse gap] rear mechanism. Dig out a 7-9 gear job which is an encouraging 3/32th" only to find is not long enough and this time no spares; went down LBS nothing longer than 116 links in any chain - and i need at least 124 - so have to buy 2 chains and then find the ones i bought are in fact too wide - because they're single speed- ok..er?... it seems all s.speed are 1/8th"- yes that critical.
So cleaned the old chain with meths and wire brush and put it back on.
Q; i suppose most electric bike chains are extra long; hoping i can use the 1/8th"s on my Lafrees - haven't looked yet - otherwise i'm stuck with a lot of useless shackles.
