Pulsar kid, yes that's what I expect will happen most often.
Olliecast, 15mph is in reality really slow and I think its not possible to get say 4000rpm below 15mph in any gear so in normal use it should never cut in. I have not tested this enough to be sure, it may need tweaking I don't yet know, but its easy to do so if necessary.
Anyone want to donate a pulsar for me to have a play with.. lol
