New to forum from Southern California. I am planning on electrifying my Vintage British Raleigh Bike. It’s a Mixte model from the 70s/80s era and I love the classic looks of it. Since the bracket measured at 40mm or less, Mid drive motor maybe out of the equation. The wheels come in at 27.5 inch.
I have a golf cart electric trolley that has a battery pack 36v==5200mAH==192.4WH and I’d like to use that for the ebike while I’m not golfing and vice versa.
Anyone here got any blue print I should follow?
Does my list of what I described about sounds promising? Do-able?

Hi; Raleigh made some fine mixte frames in the 70s, 80s. From your pic, the headtube seems very upright, Should be 70-74 degrees as I recall. I would examine the frame for any damage before starting the project. On a closer look, it's probably a photo illusion. Your bike appears in beautiful condition and the mixte is an ideal basis.

What's up fellow Vintage Raleigh owner.i too have an antique Raleigh,1967 to be exact.Its a single speed and I have a 3 speed StormeyArcher Internal geared rear hub for an upgrade. It's all flat lands where I live so there's no need for more gears for the pace I ride at I was seriously thinking of converting to electric assist but I still like to pedal the ole Gal. Let me know if you convert and how you made out. Pleased to make your acquaintance VictorObrian

Hi again; A word of warning for Raleigh bike modifiers: Nearly all bike manufacturers were frame builders and assemblers using stock parts; off the shelf. Not Raleigh nor Schwinn. Both, especially Raleigh, pre 1980s, manufactured there own stuff. While during this period there was a lack of interchangability due to different metric specs from Italy, France and Britain, Raleigh was notorious for doing things their own way. Example: Cottered cranks on Raleigh have the cotter pin 180 degrees off from common practice which loaded the fat part of the pin on the down-stroke. In reality, this mattered naught, but whene we would service Raleigh brackets,, we'd "correct" their error.

Love the Raleigh. The wheel and tires: What sizes? These conversions will have a problem when using larger tire sizes. The clearances are not there, in most cases. Especially with fenders.
On my Genze e22b, I have used Schwalbe 2.35 tires in place of 1.75s. My max inflation pressure is now 25# which may not be enough!

On mine the factory tires are 26 x 1⅜ , approx diameter of factory tires is 665mm. The new tires are 700 x 28c, and have a diameter of 685mm meaning the edge of the tire is about 10mm closter to the fender. I had to make longer fender stays to push the fender out a little so they didnt rub the tires.
