Shift Kit and 3 speed hubs

[Venice Motor Bikes]

A little update on the 8-speed hub... I took the rear wheel off to relace it for the front disc hub, & I put the new rear wheel on for a test fitting for the custom rear disc brake mount.
Here's a pic...

Howdy. My Cranbrook now has the shift kit ,sturmey 3 speed hub and a brand new honda GXH 50. The sturmey's cog is a 23 t. 1st 2cd and 3rd seem to be properly spaced.Top speed so far is 31.I'm sure if I went with the 18t or 16t top end would be higher but I like the 23t. I had to make a few simple mods. 1st was a sturmey hub anchor [my term] that keeps the hub axel from being pulled forward and out of the drop[ out kind of crude looking but it works. 2cd is a device that i installed that keeps the jack shaft parallel with the bottom bracket and the sprockets aligned. This was a must for me.No matter how much I tightened the jack shaft it would always twist. 3rd is a jack shaft chain idler[adjusting the chain is a pain]. Total of 100 hilly miles on the set up with no problem. I dig it

Here's some pics of the (slow) progress on the Slater.
I had the large parts powder coated black to match the bike.

Hi, I know this thread is old. But I was wondering how these internal geared hubs were holding out. And wich ones worked best so far. Thank you for any info.

Who knows where I can get a threaded freewheel sprocket in a 3 speed to fit an Aluminum Mag that has a jackshaft kit mounted already ? Will need derailleur and shift lever as well , not a twist handlebar Gear selector

Look at eBay I've seen 3 speed sprockets and the few other things you need .https://www.google.com/search?q=3+speed+sprocket&ie=UTF-8&oe=UTF-8&hl=en-us&client=safari

I've checked out all eBay 3 speed sprockets and it's doesn't accommodate the 415 chain . I'd have to use a stock Bicycle pedal chain , I have too much motor for a pedal chain . The sprockets aren't spread enough apart for the 415 .. May just us jackshaft with single sprocket

A BMX chain is pretty stout. What motor you running?

 

[CraftsmanJB]

What's the number on BMX chain ? My motor just had been totally broke down and restored , balanced. , with all the fancy porting / decking / Rod / piston / cylinder work and comp 5.8 Fred Head and some other tweets . Big ole 19mm Mukini

 

[CraftsmanJB]

Piston ramped , drilled to match exhaust and intake / huge reed kit too . Balanced Crank . It definitely will get up and run like a raped Ape .. lol

Its a 410 like a bike chain. I have run a 5hp 4stroke on one. They come in 1/2 link also. makes setting chains easier.
