The reduced need for adjustment in shaft-drive bikes also applies to a similar extent to chain or belt-driven hub-geared bikes. Not all hub gear systems are shaft compatible.

I am hardly a world-class pedal monster, 6' and lbs, and that answer did not impress me, as someone who was such a cycler would ruin this thing in short order. I kept the bike for a time, opening the case and re-greasing the gears whenever they started to make noise, but that ended up being almost as much work as the chain had been. For some reason I never had any problems at the hub end. They agreed to accept a return of the bike, and they told me that they were working on an oil bath system for the front gears. I was very interested in that, and volunteered to be a tester if they needed one, but I never heard anything more about that from them.

However, I also never went back to their site to check. Given the design at that time, I don't see how it could hold up to anything but light use, as there was no mechanism to move the grease back into the gears, and use would unavoidably force the grease out. From a road crud maintenance perspective, though, it was a dream. I had high hopes for it, and also looked into other shaft drive options at the time there were two, if I recall correctly. None of those folks recommended it for what I was doing, though. My dream commuter bike would be one with a Pinion transmission and a shaft drive, but somehow I think I shouldn't be holding my breath waiting for one to show up.

I have now covered about 10,km on my XDS shaft drive bike in about 2 years with no problems. Everything working just fine so I'd say the long term prospects are good. I totally agree that the proprietary components would be close to impossible to source, these are the frame and the shaft drive system. I do have access to a complete spare shaft drive system which is a plus All the other bike parts are readily available standard components so not an issue at all. In fact they could be used to construct a conventional chain drive hubgear bike with an appropriate frame.

It seems the opportunity to purchase these bikes has almost gone I believe they are no longer in production. Dynamic Bicycles USA, a main player in this area no longer manufactures or sells this type of bike. Not sure about XDS, maybe just selling existing stock. I'm pleased with my purchase I also have the Dynamic Tempo. It has the latest 4th generation Sussex shaft drive, which is an excellent idea in itself but I think is a bit flawed design due to glued gear half-casings on both ends of the shaft tunnel. The factory original glue is weak and can crack in time with frame flexing making the gears go loose under enormous pressure and thus out of alignment and I think it's what happened to above user experience with broken gears.

Mine was OK for exactly kilometers since new, then the noise came while pedaling and grew exponentially stronger. I was very dissapointed indeed, since I love the system and the bike but expected this part to last at least more than 5K before any wear problems might occur. I built myself a specialized tools for it and completely dismantled the Sussex shaft drive. Found the probable fault was the loose glue that loosened up the rear gear under pressure from the frame flexing. The problem is you can't weld it together to perfect the design since the gear casings are rotationally tightened on both ends, so it's hard to find the right angle fitting on the bike, hence you have to glue them at the same time you put it together and mount it on the bike making it a very fiddly job in practice.

I'm thinking welding one side of the shaft tunnel permanently and leave the other with glue so I can tune the right angle to fit on the bike yet preserve much better rigidity against possible flexing damaging the glue. I also replaced all the unknown brand bearings inside to high end NTN quality bearings. Once I finish my "Sussex improvement project" I'll see how it changes the game in terms of reliability, come spring. Visually Brik and Beixo bicycles used Dutch-built shaft drive is a better shaft casing design, ditto the older 3rd generation Sussex drive, since they all have the both gear half-casings fixed with 4 bolts on a fixed angle, hence the shaft tunnel is better fixed on both ends and you can weld the tunnel itself onto half-casings.

It may not look as good and elegant as Sussex 4th gen drive, but from my experience it's a more practical design idea. Overall I find the shaft drive a godsend, since I'm sick from chains and oily sprockets having them bringing dirt, noise and misery all my life so far. Thus I will keep on using and preferring shaft drive bicycles and motorcycles but at the same time I hope some clever engineer does a proper job designing and building a complete and perfected shaft drive system that compensates the current design downfalls - it's very doable, just needs a tiny bit more thought to perfect it. I've had two of these bikes since , but I have changed gear in the crank once during that time. The earlier layout with the shaft inside the frame made the gears to go out of alignment due to flexing of the fram causing the gears to wear.

And now have not been able to source this gears and the production have moved to mainland China, and their mailserver bouncing my mail. I came to this site while searching for a "Sussex shaft drive" replacement. I bought a bike, something called "dynamic tempo," in It has been great, up until yesterday. While riding it, the pedal seized. I opened it up today, and a couple of gear teeth are broken. So it lasted just under 3 years. Very useful information from Margus regarding the detailed assembly of the Sussex shaft drive. I wasn't aware the tube and end assemblies were fastened with an adhesive.

I thought they were a press fit or threaded. I had cause to dismantle the front gear box which seemed to be noisy The main problem was actually a faulty pedal bearing, but there was some noise from the gear assembly due to incorrect lubrication. There are no effective oil seals on the spindle so it tends to leak through the crank bearings Apart from these issues it is still working fine. I got an almost complete spare shaft drive assembly from the XDS Australia importer. They were still holding spare parts for the range of Dynamic bikes they used to sell, probably the only source of parts for these transmission systems. They did respond to emails for a while and then disappeared d. XDS Australia no longer list the range of bikes, they were products handled by Lifespan International and sold on eBay.

Maybe they still have some stock if anyone is interested. They are very interesting pieces of machinery. Sign up to join this community. The best answers are voted up and rise to the top.

Interestingly that website also advertises their bicycles, but not shaft-driven bicycles.

I does seem that the mechanism would be heavy and expensive, with few advantages in normal use. I can't see them being used except in special situations or unless they somehow become all the rage, of course. Here's a review online - you may have seen it, but the dealer happens to be near me.

So when I talk about longevity I'm talking on those terms, rather than shorter distances or replacing the bike every year or two. I fear you'll find out in 5 years time that everything on the bike is wearing out but you can't service the shaft drive so have to buy a new bike.

I also have the same model XDS, and sadly the shaft drive had a terminal failure within km or so It hasn't given me a lot of confidence for the next one, though. Add a comment.
