Crikey, that is some powerful bike.

Being working on the electrics. Very slow and fiddly, but things are starting to come together. Here's the high voltage DC side.
The thing far left in the foreground is the vacuum pump which will drive the servo. Control electrics, fuses etc will be on the left, above the wiper motor.

Not on a public road of course....

The 250W limit on bikes is ridiculous. Should be 1KW.

I really like your project! Just read through the comments.

It's quite a powerful setup you have, 0 to 60mph looks like it'll be dam quick.
I didn't read what size power pack ?Wh. I'm guessing this is going to be substantial from reading weights quoted and performance expected.

Did you consider in wheel hub motors? Seems a very practical approach although possibly no match for the hefty motor fitted.

Looking forward to your progress updates here.

Best regards, Robert

Thanks Rob,
I'm thinking 108s75p if the 1.2ah, 3.2v cells I've got, which works out at about 30kwh? But really dependant on what I can do with the scrap batteries I got.

I did consider using a Sierra or mx5 type rear axle/frame, which would have made in-wheel (more likely in-board) motors possible, but cost and fear were limiting factors...

30kWh pack is substantial for a project build, should get a 100 mile run at least.
Have you done any checks on your battery cells? there's many poor quality china made types out there. I did go through this process when building a 200Wh pack for an e-bike. Got great results from Turnigy hobby Lipo packs in the end and ditched the 18650 cells extracted from new laptop packs.

Will you need to get DVLA type approval before road use?

Cheers, Rob

Whoop! Whoop!
Got the rear wheels turning last night. Wiring harness has been swapped to the other side of the car. Pretty much 'started' first time.
Here's the wiring as it stands so far.

Crikey, brake pipe unions, what a pain!
There's a saying - "The great thing about standards is there's so many of them."

I think I've finally got it figured out:
As far as I can tell, original union size on all moggies was BSF 3/8" throughout. I'm not completely sure about this 'cos ESM are selling a "Bridge - Front Cylinder To Cylinder (UNF) December 1953 Onwards".
Good diagam here, with apologies https://www.mmoc.org.uk/Messageboard/viewtopic.php?t=43353 )
Fluid reservoir, to master cylinder - 10mm
Master Cylinder, from reservoir - 10mm
Master cylinder, to servo in - BSF 3/8"
Servo, from MC - UNF 3/8"
Servo to 3-Way + Switch - UNF 3/8"
3 Way + Switch, to Front 3 way - BSF 3/8"
3 Way + Switch, to Front 3 way and Rear Hose - BSF 3/8"
*1 Front 3 way - all BSF 3/8"
2 Front JLH disc hose - both BSF
*1 Rear hose - BSF both ends
*1 Rear axle 3 way - all BSF"
*2 Rear cylinders (ford mk1 8" drums) - UNF 3/8"
