Done a search on the subject of electric reverse for a BEC but can;t see any photos of anyone's installations.

Can anyone point em to any or to any members who might have photos in their archives?

Sounds to me like it's just an electric motor that runs against the hub or just inside the back wheel, like a 2 fingers to those who say you need a reverse.

If it's any other way I'm interested too

Here are a few

And there's more.........

Where can you get the large cogs from and what sizes are available?

That's one propshaft you don't want to let go!

The one mounted to the diff looks like the flex-plate from an automatic (autos have this instead of a flywheel, same dimensions but very low mass). Pretty much all autos have one and if you can get the starter off the same engine you will have a nice matched pair for next to nothing. They are obviously fairly large diameter so make sure you have the clearance for it though!

Whats happened to the teeth in pic 2?

Are the starter motors permanently engaged then and turned by the engine during normal running? or do they work like a normal one and only engage when the bendix flings it forward?
Is the switch rigged up so starter motor cant be powered up when car is running forward?

If you are on a hill, is there enough power to make the car drive backwards up the hill? or do you need to be on a flat first to get it moving?

Im just interested how they work in practice, i guess they work very well if the flywheel is lcorrect size to help the gearing.

The big green pics are mine - yeah choice of kidneys or ankles..... The gear is in there as it's also the handbrake but I've still not done the electrics for it yet (too many other projects) and it IS a PITA having to get out and push backwards. Maybe I'll get round to fixing it this winter...
I got the gear specially made by an old geezer in Middlewich I think - it had to be a special to fit in the tunnel & mesh with the starter motor. And it's made of stainless. The teeth are OK, there's an optical illusion in the pic....
The plan is that the starter motor engagement solenoid will be interlocked with the bike neutral switch and instead of directly powering the motor, it will do so via a PWM controller. That gives fine control and a useful current multiplication at low voltage output.
