So, now I've basically built the bike I've always hankered for I'd like to build the second bike I've also hankered for

Which is a shaft driven , hub gear bike that I will convert with a front hub. Why, I want tomake the ultimate in bullet proof, low maintenance , fail safe , deep winter commuter

And IMHO it has to start with a shaft plus hub set up

But I cannot blooming well find one. I want a cheap 2nd hand doner bike not new. A few years back eBay seemed covered with them with 50 to 100. Not anymore

If the forum would care to assist or see anything then do let me know

Let's say 150 budget. Tbh I care only about the frame and the hub gear set up working. The rest I can almost certainly replace from quality shed spares. Although , actually, disc brakes are are a requirement too. 26, 700 or 29er all work for me

Cheers

Have you see this

https://www.ebay.co.uk/itm/Sussex-Drive-Shaft-for-chain-less-bicycles-for-bikes-with-internal-hub-gears/223157139533

Rather than be limied with a limited choice of OEM shaft driven bikes you could convert any viable frame type...
It’s a nice idea wicky

Sadly frames have to be built around the drive so these are only any good as replacement drives for broken OEm bikes. Bit like you cannnot retro fit a Bosch drive

At least that’s my understanding !

you can change the motor mounts as seen a bosch bike fitted with a steps motor.

tho you have to have a custom bracket made.

Think you might have missed the point SW

I dont think you can buy the linked shaft drive and retro fit to a hub bike with a chain....the frame will be wrong. I used the Bosch drive as an example of something that cannot be retrofitted to a “standard” frame

Indeed, usually the shaft casing takes the place of the right hand chainstay of the frame. It might be possible to cut the front of the right hand chainstay from a standard frame that suits shaft centres of 20" or about 17", rewelding it higher and modifying the BB area like the one below. Big job though:

I'm not really questioning the quality of the Ebay shaft drives, but I'd certainly want to see and hear one in use before committing to buying and fitting one.

I love the idea though, not least because it would be so different.

I still have a Thorn Nomad that I took as payment for some work that I carried out, sitting around waiting for me to do something with it. :)

They are “Sussex” drives made in Taiwan. Really only replacements for oem bikes

I suspect the reason they are available is Dynamic bikes appear to ha e given up on retail bikes. They appear to be concentrating their efforts on USA campus , pool bikes type thing

So they got plenty spares but no bikes to sell !

I’ve ridden a Sussex Drive bike before . I thought the drive was great but rest of components were terrible. It was like 90% of cost went into hub and shaft

The Beixo from Holland seems to have combined a drive shaft with a Bafang mid-drive.
From the pictures it looks like the chain stay and BB are in a conventional position with the driveshaft beside the chain stay.

The photo of the blue one is clearer and seems to show only one chainstay, the shaft being the right hand one. That's common practice on shaft drive bikes as their folding models show:

Oh gosh, I'm inherently very wary of no chainstay. I didn't know that was common. It goes against my principle of Trying to build the most bullet proof, e commuter possible

I think it narrows my search down to an old Dynamic bike on a 2nd hand page tbh

I may have found one but the head tube looks very odd. If I can't replace the headset, forks, stem then it's a no no

Going to see a bike this weekend that looks ideal

It’s a shaft driven , alfine 8 setup

So only front conversion possible. But the Ali forks look very wimpy . I think they’ll need swapping out

What motor to put in ? Been a while since I had a front hub !

Suggestions please ? Happy to stick with 250w motors as this is a winter commuter but scope for speed limit removal (either by lcd or overvolting). 36v is a must as my other bikes run 36v and I swap batts around

Search over !

Just picked up a Dynamic tempo , alfine 8 in top condition, rarely used with all original paperwork.

Feels great to ride and whisper quiet

Needs new bars, stem and a brake upgrade to hydro (all of which I have in the shed )

And then a conversion of course

Looks good as the basis of the low maintenance commuter you want, and has the desired twin chainstays too.

I'm not up to speed on today's front hub motors but hopefully there'll be some suggestions coming in. You haven't mentioned the terrain or whether you're looking for light assistance or plenty of power?

Hi flecc,

My commute is flat along the seafront (though winds can be fierce !) . I have a mtb mid drive for torque

This bike I am going for low assist, small hub

I’ve been pointed in direction of MXUS ytw-06 as the smallest but I’ve yet to fully measure up my options

And am still considering a fork change to 700c hybrid suspension fork

MXUS XF07?
YTW-06 has lower weight (-1kg) but it's an unnecessary trade-off where weight is not so important.

Kirstin the YTW06 is a Xiongda purchased direct, no middle man.

Sorry , that was a typo/error as Neal points out

It the xiongda ytw 06 which is significantly smaller than a q100
