So, I've bought an electric bike "project", now starts the questions!!

[Cheapskate]

I threw £50 at a 2007 Barracuda Colt with 24 volt front wheel drive on 26" mountain bike tyres. Came without battery or charger, which I have sourced as a frog battery stem set.
I tried it with a 24 volt source and it zipped off fast but erratically, so the motor seems to work, but I suspect the wiring to be iffy!
I can see that the PAS has been reversed and has a 10mm airgap so I will set that right when the battery etc turn up.
In the meantime, this beast of a machine has a 3 position rocker switch on the left handlebar marked A, 0, and A/E (wires red, blue and black), also a greeny blue unmarked pushbutton on the right handlebar with 2 wires disappearing into the loom.
As I am starting on a voyage of discovery, can someone maybe shed some light on the function of these so I have some initial idea?

Many thanks in anticipation, Pete

Don't mess about with the PAS. There is no correct direction until you test it, i.e. don't take any notice of markings.

The switch is probably PAS only, of, throttle and PAS.

I'd get rid of all the electrics except the motor and PAS, get a 36v controller and any 36v battery you can conveniently fit. Nearly all electric bikes are very under-powered at 24v. Every time someone asks me to fix one, I convert it to 36v and they love it.

Show photos if you want more specifiv advice,

Thanks for your informative reply to someone who had never sat on an electrically assisted bicycle until last week!
I attached the photos relevant to my initial query ie the markings/ purpose of rocker switch along with wire colours, the push button, and for reference the PAS which is patently not correctly set at the moment.
To expand, this bike will be used for a 4 mile commute across mainly flat Essex roads, with a handy 8 hour shift to recharge. I figured that by fitting a new battery to the existing stem mount and controller the bike would probably manage that?
Also, I imagined that setting the crank trigger wheel correctly would be an obvious first step to getting this behemoth moving?
New battery is presently on charge....

Ok, if you know all the answers, it should be pretty straight forward then.
