Adrian Posted November 4, 2008 Report Share Posted November 4, 2008 im so sorry if this is a repost, but its new to me....[] click me []you recon they could use thisin trials? Quote Link to comment Share on other sites More sharing options...
NVWOCI WVS Posted November 4, 2008 Report Share Posted November 4, 2008 it's been brought up before. i dont reckon it would deal with the torque too well. Quote Link to comment Share on other sites More sharing options...
ben_travis Posted November 4, 2008 Report Share Posted November 4, 2008 The only place this will take off (in my opinion) is hybrid / commute bicycles! It only has three gears, which would not make it useful for any discipline other than the aforementioned.There is no way it could handle the rough and tumble of trials...even if it could manage to handle the torque, what happens when someone lands on the tube, or falls off their bike and smashes it into a rock. (as an example).Maybe I will be proved wrong, but im 95% sure I wont be! Quote Link to comment Share on other sites More sharing options...
Adrian Posted November 4, 2008 Author Report Share Posted November 4, 2008 yea, your right... same as what iw as thinkingbut lose the gears, and make a real sturdy single speed one xDprobs will never happen but i wouldnt say its impossibleits prabably the same sort of stuff people said when they thought about making the first ever freehub/freewheel loli thought it was pretty cool though hahanice and clean nd tidy looking Quote Link to comment Share on other sites More sharing options...
CC12345678910 Posted November 4, 2008 Report Share Posted November 4, 2008 (edited) 1. LOL that looks dodged!!2. It will never take off.3. Say they did a single speed one, what would happen if the rider wanted to change gearing, eg. 18-12 to 18-13 type scenario (SP??)? 4. Crash proofing would be a major issue Edited November 4, 2008 by CC12345678910 Quote Link to comment Share on other sites More sharing options...
tris Posted November 4, 2008 Report Share Posted November 4, 2008 I think it's pretty decent. It simple for a start. Also if they created a rear cog with a universal pickup, it could be used for a number of gear ratios on the rear, they could be interchangable (not as easy to modify the front gear).I prefer my good old chain system though. The direction of power doesn't have to be changed and then changed back like in this system which will cause more strain and make it more fragile.

Rusevelt Posted November 4, 2008 Report Share Posted November 4, 2008 It will never make it to the trials scene, though it would be interesting to know what it rides like in terms of the pick-up and torque. Quote Link to comment Share on other sites More sharing options...
aener Posted November 4, 2008 Report Share Posted November 4, 2008 Bikes just look clean as hell when there's next to no visible drivetrain...I wish someone'd think up a decent chain alternative... I hate fiddling with mine Also - does that one adapt for different length chainstays? Quote Link to comment Share on other sites More sharing options...
Fixed Pants™ Posted November 4, 2008 Report Share Posted November 4, 2008 It's a shame it's on such a shite bike/set of bikes... Quote Link to comment Share on other sites More sharing options...
shamus Posted November 5, 2008 Report Share Posted November 5, 2008 weight!? thats gotta add a fair bit, one sided as well and ye changing the direction of power via bevels can produce really weird torque effects and twist things in new ways meaning the frame would probably have to be massive to deal with the stresses.works well on the BMW tourers mayb we could have something like this if we are going into this technologyhttp://www.christini.com/awd-technology.php all wheel drive!

Luke Rainbird Posted November 5, 2008 Report Share Posted November 5, 2008 It's pulled over from motorbike tech (cruisers and the like), but yeah for trials it'd be pantsYou wouldn't really be running 22:18/whatever either, though it'd be pretty much constant engagement, maybe a tiny bit of slack in the splines Quote Link to comment Share on other sites More sharing options...

Steve-A Posted November 6, 2008 Report Share Posted November 6, 2008 Aside from all the points raised by others, there's one other factor I can see being a huge stumbling block for using a shaft drive system for trials.According to that article, and I had heard this before the shaft drive system isn't as efficient as a chain, so you would loose more power through the shaft system, and compared to a chain bike wouldn't be able to do any moves involving pedal power as well.Also on the note thats its pulled over from motorbike tech.... have a look at moto trials bikes, motor cross bikes, road racing bikes, how many of them use shaft drive? none. Its used on touring bikes and cruisers (and BMWs but they just like to be weird) not high performance bikes. Quote Link to comment Share on other sites More sharing options...
Gogz- Posted November 6, 2008 Report Share Posted November 6, 2008 Quite a few years ago I saw a Pashley prototype that didn't have a chain. It looked so sleek and so simple (obviously isn't but you know what i mean) but as far as I'm aware they have never brought it out so there must be something wrong with the mechanics of the idea Quote Link to comment Share on other sites More sharing options...
Spider Lad Posted November 6, 2008 Report Share Posted November 6, 2008 For the serious cyclist after a performance machine, then this system is a no.For the casual rider or commuter who won't appreciate the difference in efficiency or ride over a quality 'traditional' machine, but enjoys the novelty, then this bike might keep them happy.

PaRtZ Posted November 7, 2008 Report Share Posted November 7, 2008 2. It will never take off.you've heard of the term "Thats what they said about mobile phones" ...Nice to see deas still going round the bike market, shame they're not ALL step forwards but as said this one is, and could definitly be used on commuter bikes Quote Link to comment Share on other sites More sharing options...

bendy Posted November 10, 2008 Report Share Posted November 10, 2008 I think another massive problem is going to be the number of components a person would have to change at once to "upgrade" to this system.(frame,hub,crank) The shaft wouldn't be to hard to protect would it? Possibly another tube running under it.Basically if a trials company brought it out i wouldn't be interested until I had seen it hammered and come back asking for more.bendy Quote Link to comment Share on other sites More sharing options...
