I've had my P6R (second hand) for something over six months. I just find that you have to be careful. If I can, I rotate pedals forward into roughly the right position, before folding. It's quite unpredictable.
I don't see any reason to clean in any other way than for a "normal" bike. I've used a chain bath and so on.
Thanks
- I took a closer look this morning, the chain tensioner was very wobbly, the retaining nut was only just on, so I think that was the main culprit. Whilst I was there I gave it all a good clean, there was lots of gunk in the drain holes of the tensioner pulley as well, took out the indicator chain and cleaned and lubed that and cleaned the chain etc. I could have saved the last job if I had bothered to measure the chain *before* I cleaned it, it's very worn!
I think the original owner did about 1100 miles on it before I got it, so suspect it also needs a new chain.
Anyway - now it's re-assembled, reversing the direction is no longer causing grief!
I think I'll pop out for a coffee and call in to our local Evans for a new chain this morning
