I ha...Hi, I just found your review of the Moulton. I have one of these (TSR 9) as well as a very low price Dahon Vitesse folder, and a road bike. <br /><br />The UK price of the Moulton TSR9 is currently between £1200 and £1350 depending on the paint. It’s a bike with front and rear suspension, a nine speed drive, V-Brakes, and flat handlebars. The suspension damping can be adjusted, it can be locked solid (with a spanner) or the preload can be adjusted for the riders weight. <br /><br /> The frame is nicely finished, but Moulton, even at this price range fit the bike with low price components – the derailleur is an SRAM long cage – a short cage would fit, but maybe Moulton believe riders may want to upgrade to a triple crank. V-Brake levers are low-price Avids. <br /><br />There’s no side-stand, and it’s hard to fit one. There’s no luggage rack and Moulton ones are pricey. There is an adjustable stem for a small range of height adjustment, but the bike will not suit the petite. <br /><br /> Cost cutting is evident all over the bike. The serial number is not stamped into the frame (that I could find) but is a sticker. Wheels and hubs are low price Quando cup and cone wheels, as on the Dahon. Chainset is a low-price Sturmey Archer. There’s no replaceable derailleur hanger – the frame needs a repair if you snap off the derailleur – unthinkable on a 21st century bike. The frame doesn’t fold, but can be separated into two pieces. The star-nut cover on the fork tube is cheap plastic. <br /><br />In comparison, the Dahon Vitesse has seven gears, folds easily, has very similar components, is lighter than the Moulton, won’t rust, and the derailleur hides under the chainstays. It’s an altogether more complete design, rather than a series of compromises bolted to an expensive frame. It cost £350 new. <br />What the Moulton is then, is a hand-made anachronistic expensive Brit throw-back suspension frame, with low-priced components. It rides pleasantly, but so does the Dahon. Even at £1200 the Moulton needs a short cage derailleur to tidy up the rear wheel and prevent frame breakages, at least. <br />The problem is that the Moulton sells on its heritage. But 21st century bikes like the Dahon are similar equipped and more versatile. But, the Moulton has suspension. So, that’s kind of where I’m at; a Moulton owner, but not an impressed one. <br /><br /><br />Sam, London, UKAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-7129037502516609710.post-46360967603833566552012-10-16T23:28:12.902+01:002012-10-16T23:28:12.902+01:00@ David Hembrow

The bigger wheels are obviously heavier, meaning more momentum to keep the vehicle going after <a href="http://wimschermer.blogspot.com/2010/04/bandentest-26-banden-tire-review.html" rel="nofollow">rolling down the ramp (see pictures)</a>.<br /><br />If you look at the tables David links to, you can see that among the four models of Durano tyres, the heavier ones rolled further than the lighter ones. Ditto for Kojaks, the heavier Kojaks rolled further.<br /><br />I don't know Dutch so I might have missed something. Maybe I should work up the courage to comment on their blog directly, unless someone can explain where I went wrong here :)<br /><br />I'm biased as a happy Brompton owner. I don't feel wheel size makes a practical difference. In a test in Bicycle Quarterly Summer 2011, they couldn't detect a difference between three sizes of Schwalbe Marathon, 622mm, 584mm and 559mm.Erik Sandblomhttps://www.blogger.com/profile/14411108063216855210noreply@blogger.comtag:blogger.com,1999:blog-7129037502516609710.post-29789979916696275582011-09-25T02:00:34.765+01:002011-09-25T02:00:34.765+01:00Just came across this review; I haven't had th...Just came across this review; I haven't had the pleasure of trying out a "belted" Moulton, but I don't see there being any major issues with this drivetrain, especially given the bike's target audience.<br /><br />As far as wheel size and performance goes, I can only give anecdotal evidence. I purchased my AM14S ("Sport" specification with drop bars, 9-28 rear seven-speed cogs and 52/62 chainrings) 26 years ago - almost to the month. On club rides I would regularly be queried as to whether it was a good idea to try and hang with the pack on the thing; Before long, the other riders would line up to take turns tolling around parking lots during rest stops, pretty much shocked at the comparatively silky ride and nimble handling and acceleration. (Suspension was at most a MTB novelty at the time, if that, and a totally alien concept for roadies.) This was, however, before the delivery of my AM/Zzipper fairing; the thing was suddenly so fast that I was frequently goaded into taking paceline pulls. I'd be lying if I said I didn't like all the attention.<br /><br />And, all these years later, it's my favorite of my three current bikes. Expensive? Yep. (If I had it to do over again, I couldn't sadly.) But when you still love a bike like this after a quarter of a century, is initial cost, assuming you can somehow swing it (and thinking about what people pay for cars that won't last nearly as long), <i>that</i> big a deal?Barretthttps://www.blogger.com/profile/14698894135761271569noreply@blogger.comtag:blogger.com,1999:blog-7129037502516609710.post-70744918512482816892011-08-30T09:00:23.528+01:002011-08-30T09:00:23.528+01:00Although Dr Moulton is undoubtedly a pioneer in bi...Although Dr Moulton is undoubtedly a pioneer in bicycle design, I feel he missed an opportunity in failing to develop a Moulton recumbent. Apparently he doesn't like the recumbent position. Certainly for town riding the recumbent isn't ideal. I have converted a series one Moulton into a recumbent and can only say it is a vast improvemnet over the original in terms of speed and comfort especially for touring. The biggest drawback with this bike, apart from town riding, is the weight; despite this I travel significantly faster than on an upright. I can only imagine what the latest Moulton would be like as a recumbent (cycling Heaven)!Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7129037502516609710.post-41434739851807508762011-08-08T20:02:40.510+01:002011-08-08T20:02:40.510+01:00I've been riding a belt-drive Spot Rocker SS f...I've been riding a belt-drive Spot Rocker SS for a year now (Spot Brand being the Golden, Colorado, USA company that worked with Gates on the original belt drive for bicycles). Though it does have some downside, I am generally very impressed.<br /><br />The good: Never needs oiling, so it's super-low maintenance and it won't leave lube on your trousers. It is incredibly silent. I find myself accidentally frightening pedestrians as I approach from behind. The belt is said to last 5-10 times longer than a standard chain. I don't know yet, but after a year I still cannot detect wear to the belt or pulleys.<br /><br />The less-good: The biggest issue is that changing the gear ratio is more complex than usual. You can't take a "link" out of the belt, so pulleys and belt must be ordered as a unit after precise calculation. The pulleys and belt are expensive, maybe 2-3 times the cost of standard cogs and chain (though with their longer wear it could be argued that they're a bargain anyway). The belt can, at times, slip off. Thus, the new design with a center channel on the belt matching a groove of the pulleys to prevent this. The belt requires pretty high tension that may be difficult to get just right.<br /><br />With the help of my local bike shop I'm now up to speed on the tricks of belt drives and am completely sold. All my single speeds have belts and I doubt I'll ever go back to chain drive.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7129037502516609710.post-63707687027824978092011-07-06T19:04:15.425+01:002011-07-06T19:04:15.425+01:00I'm 52 and ride an old APB fitted with an 8sp ...I'm 52 and ride an old APB fitted with an 8sp Shimano internal hub and cheap BMX road tyres.

I've always s...Look, Moultons are lovely bikes. I've always said so. However, that doesn't change anything about small wheels simply not rolling so fast as larger ones.<br /><br />This is not merely theoretical. Measurements of rolling resistance consistently show the theory to be correct. And yes, it is indeed "immediately obvious" when it is actually tested properly.<br /><br />For example, <a href="http://1.bp.blogspot.com/_cFao0zH2oMg/S75Rn0H5LjI/AAAAAAAAGR4/YGlrYRBLng4/s1600/Test+26+met+grafiek.png" rel="nofollow">a 28-559 Durano</a> at 10 bar rolls 42% further than <a href="http://2.bp.blogspot.com/_cFao0zH2oMg/S70DW8jv_mI/AAAAAAAAGRQ/42_5-IP6tyk/s1600/Bandentest+20+inch.jpg" rel="nofollow">the 28-406 version</a> of the same tyre. The difference in diameter is around 37%, so this is incredibly close to the theory (results from <a href="http://wimschermer.blogspot.com/2010/04/bandentest-overzicht-20-en-grafiek.html" rel="nofollow">here</a>).<br /><br />Suspension helps a lot with ride quality of smaller wheels, but it does little about the rolling resistance per-se.<br /><br />Why make an assumption that a larger wheel bike will not have suspension ? If you're going to use this argument, compare like with like. Many bikes with 26" and 28" wheels have suspension.<br /><br />While wheel size is always an issue, it isn't the only important factor. Good quality, high pressure, slick small tyres with skin-walls will roll better than low pressure, low quality larger tyres with thick side-walls. What's more, above 18 mph or so, aerodynamics are much more important than rolling resistance. Therefore, for faster riders the difference due to wheel size becomes smaller.<br /><br />In the 1960s, Dr Moulton took care to have <a href="http://www.users.globalnet.co.uk/~hadland/tyres.htm" rel="nofollow">specially made extra light rolling tyres</a> made for competition using his bikes. These helped the bikes to take some records.<br /><br />There were also records set using aerodynamic assistance, and indeed some people <a href="http://www.moultonbuzz.com/2008/04/moulton-hpv-racing/" rel="nofollow">still try this</a>. It will give an advantage over a normal bike because it counters what is a more significant problem than rolling resistance once you gain speed.<br /><br />However, the fact remains that slower riders exert comparatively more of their effort against rolling resistance, which increases linearly with speed, than they do against aerodynamic resistance, which increases with a log law. As such, a slower rider benefits to a greater degree from larger wheels.<br /><br />I'm not against small wheels, I'm just against nonsense being disguised as fact. My fastest bike has the same wheel size as the Moulton under discussion. As they, and their suspensions struts, fit inside the aerodynamic shell, the combination allows me to ride faster than I ever have before. Indeed, last year I averaged <a href="http://hembrow.blogspot.com/2010/06/cyclevision-2010.html" rel="nofollow">not much under 25 mph</a> for the duration of a six hour long race.<br /><br />The small wheels don't help with this. My bike goes fast <i>despite</i> their higher rolling resistance. It is possible because in this case other factors more than compensate for it.<br /><br />However, those factors don't apply to the Moulton above. To do anything like that speed for that duration with that bike would require someone with superhuman strength who could also keep up an impossible cadence. I know I'd do better on my normal Dutch town bike, or indeed on my old English roadster, than on this particular Moulton with high rolling resistance and what for me would indeed be rather too low gearing.<br /><br />You simply can't disregard physics.David Hembrowhttps://www.blogger.com/profile/14543024940730663645noreply@blogger.comtag:blogger.com,1999:blog-7129037502516609710.post-65354376108303129122011-03-28T08:45:39.045+01:002011-03-28T08:45:39.045+01:00Just to add to the comments regarding the rolling ...Just to add to the comments regarding the rolling resistance of smaller wheels, my experience as an owner of a Moulton (New Series, and in the past an AM5) as well as 700c bikes is that there is no noticeable difference.<br /><br />Granted, highly unscientific - but if the difference was as much as 50%, as suggested, it would surely be immediately obvious.<br /><br />The suspension also reduces total rolling resistance, since on unsuspended bikes the entire weight of the rider and bike (60Kg+) has to be lifted over any bumps or surface irregularities in the road. With any realistic road surface, the cumulative drag this adds must be significant.<br /><br />The gearing ratios are indeed quite low, but they seem well chosen for city riding - one easy gear for starting off from traffic lights, and one for city cruising speeds. Ccertainly in London, I can only rarely travel faster than 20mph due to traffic etc.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7129037502516609710.post-17801023484612765662011-03-26T20:43:26.115+00:002011-03-26T20:43:26.115+00:00Nice review :-) I have one, in electric orange... ...Nice review :-) I have one, in electric orange... have to put you right re luggage capacity, though.

"...In response to David Hembrow's comment:<br />" Larger wheels not only go over rough surfaces better but always offer lower rolling resistance than smaller wheels. Diameter is a part of the basic formula for rolling resistance. Your legs have to put in 50% more effort to overcome rolling resistance of ETRTO 406 wheels vs. 622 wheels, if both are fitted with similar tyres."<br /><br />There's more to it than that. Using the first formula in the Wikipedia article that you linked (a more widely-accepted formula than the one you used) gives a 24% difference in energy loss between those wheel sizes. But that's not the whole story either. We're comparing a small-wheel bike with suspension and a large wheeler without. The suspension actually reduces energy loss because the rider's body is shaken up more on the unsuspended bike and that actually consumes energy too.<br /><br />In practice, all this is amply borne out by the experience of the many Moulton riders who happily keep pace with large-wheeled riders in club rides, Audaxes and the like. And as you yourself have said elsewhere (http://hembrow.eu/moulton.html):<br />"Dr Moulton's theory that a bike with small wheels and suspension could perform as well or better than a large wheeled bike was proven by racing versions of the machine taking some records."George Coulourishttp://www.coulouris.netnoreply@blogger.comtag:blogger.com,1999:blog-7129037502516609710.post-79355075104848167262011-03-26T10:34:49.656+00:002011-03-26T10:34:49.656+00:00Ooo!
