Which kit for Raleigh DL-1?

Ok, deep breath. I have 2x Raleigh DL-1's from 1946-1954 period and have a hankering to put an electric conversion on one of them. Trouble is they are an odd size, 635-22 westwood wheels, 110mm horizontal rear Over locknut dimension OLD, 90mm front.
The LBS can't true the rear wheel because the spokes are seized. And linear rod brakes are scary at speed (downhill). So I was thinking of going with 622-19 hub braked wheels, which makes a motor wheel tricky.
So what would the gurus recommend for an average highway rider ? Motor wheel, Mid motor, Friction! ?
Cheers, Mike

Ah, Keyde make some interesting motors, one is 80mm wide, no brake but right width, another has a roller brake but is 100mm wide.

Oh well, close but no cigar!
Bafang make a Rear Roller brake hub at.. 135mm drat, and a new 3speed rear hub 120mm wide.. but its wound for 14in,16in & 20in wheels with a 9tooth cog, shugar!
Bafang RM G353 – 3 speed hub and shifting components

20190317_172022-1.jpg Needs electric zoom zoom. I'm knackered pedaling this to d pub! Phew. (apologies for bumping an old thread, just wondered if anyone else has electriced one of these. Only found 1 account on Google of Bafang BBS conversion by cutting down BB 5mm to 70mm). Slainte. Oh and happy st pats day. Mikel

32 spokes in the front and 40 in the back severely limit your choice of motors. If you have a good wheel builder, it is possible to build a wheel with a 36 hole motor and a 32 hole rim, in which case you could use a Q85 kit from BMSbattery.

To be honest, I think it would be better to sell the bike as an antique and buy a modern one. It's going to look horrible with wires all over it.

I doubt that a mid motor will fit the BB. Even if it does, you'll lose the chainguard, which gives the bike its character.

One thing that might work is one of those really cheap brush motor kits that clips on to the side of the rear sub-frame. I expect they're pretty horrible compared with modern stuff.

Thanks for the advice, hadn't thought to count the spokes. Had considered 'easy option' of a 700c front motor wheel, albeit black & silver alloy, and 'touring' fork with v-brake mountings for my other DL-1 which is rougher than this one, and therefore ok to mod. But then front motor wheel wouldn't match a new rear coaster braked 3speed wheel available in silver, heho. (3sp is only one skinny enough to fit 110mm OLD rear)

Story i read gave no details of how chaincase was cut about to cover Bafang BBS, wish i had a pic of it to post.

If those 'Hidden Power' friction drives, mounted under the BB, were really any good more people would use them as more convenient.

You're right, it would be easier just to get an electric lookalike, like Gazelle or Cortina, as with any conversion.

Cheers, Mikel

Your brakes won't work with an ebike mote wheel because the rim is the wrong shape. You either have to cut the rim off your existing wheel or buy a similar one from Ebay, then lace whichever to the motor.

You're right, new v-brakes on a new touring fork would require a motor wheel with rim braking surfaces, which they have. Ready made alloy motor wheel kit rims tend to come in black i find. To match and stay original both would have to be custom built with polished alloy or chrome or stainless steel westwood rims that are apparently available. Don't know if I want to build up speed with only rod brakes, now if there was a motor wheel with a hub or roller brake, or do a disc brake DL-1, heresy! hehe. Cheers. Mikel

Pashley_0307.jpg Ah, it was a Pashley, not a Raleigh, that had Bafang BBS conversion. He dispensed with the chaincase, and it appears to have front hub brake, rear coaster brake, with the battery under front basket on carrier.
