    I have a newish zoombicycles engine which I've been riding for about three weeks. It misfired today when starting. The engine was warm, I had ridden about one block, came to a stop and killed the engine. When I dropped it into gear the rear wheel locked and nearly sent me for a tumble!

    Anyhow, it started fine when I gave it another go. Was that a misfire?

    nope. that was a lurking gremlin :)

    the fact it started again means theres no problems. hopefully.

    it could be anything from

    the chains too loose. when you go to start the bottom side is under tension, top gets dangly, one link tries to go where it shouldnt...bang... locked wheel. doing it at 60 will hurt... and it wont start so easily... :p

    um...you got a really tight engine and now its "breaking in" (which they dont IMO) the compression is better than average and it takes a bit more to turn over... so the wheel gets a bit stiff at times...

    flooded crankcase(kills seals, wont start for ages, sprays fuel everywhere)

    not going fast enough when you try starting. going too fast when trying to start...

    etc etc, ad nauseum

    unless the thing dies making awful screaming noises, dont worry :)

    Can you expand a bit about the flooded crank case? I'll ask a friend to help with the chain, that could be it. Happened again, jammed now.
