Thank you for making this video, your commitment to enlightening us all is admirable! I've got a 6 speed C line and a 4 speed P line, I've also had a 3 speed. My 6 speed gets the most use and I've put a 44 chainring on because, like you, I couldn't spin out in top gear and at those sorts of speeds I'm probably better off freewheeling downhill instead. I find a lower 1st gear more useful than a high 6th gear for when I'm touring. My 4 speed P Line is superb for short swift rides in the city, the titanium forks and rear along with more supple tyres than the Marathon plus on my 6 speed make it ideal for what I use it for. I'd agree completely with your suggestion to take a test ride, the gearing choice is as important to me as the handlebar type.

My Brompton is a 6 speed. Changed to 44T. Perfect for hills, fine for the flats. On standard gearing, spin-out downhill was around 30mph. On the 44T it is around 25mph. But in neither case, on the flat, do I want to be trying to attain or maintain those speeds! With a gentle following wind, 17-20 on the flat is a sustainable gait. I try and have a following wind as often as possible.

I have a 2013 M6L with a 44T chain ring, and a 2022 Ti 4-speed with 50T chain ring. There's about a 4.5k/9 lb weight advantage for the Ti. The M6L is a better climber, but if the terrain is flat (and on the flats) the Ti is just a faster bike. I would choose the M6L for Seattle, Sydney (AUS), and the Redding/Woking/Reigate UK areas, and the Ti for London/Cambridge, San Jose CA, and Gothenburg (SWE) areas. (I've ridden a Brompton in all of these locations plus more.) The light weight of the Ti 4-speed makes it a joy to tote around, while toting the M6L through the London Metro is cumbersome and tiring. As others have noted, I wouldn't choose to ride either bike faster than 20 mph... the Brompton design is more prone to flying over the handlebars and breaking a collar bone or worse than a regular bicycle (don't ask me how I know). They will go fast but aren't designed for racing/speed but instead to offer a reasonably good ride for commuting and touring at 10 to 16 mph.

I have an A Line Brompton, 3 gear Sturmey Archer hub... It's just perfect! I love it. I use it for commuting: The train station is about 4 miles away, not really hilly, smooth riding. In the city, I use it to visit patients and customers, driving a car in the city sucks. Traffic jams...And nowhere to park your car. But my Brommie does the job. And I can put it under my desk in the office! 😊

I got the M6L. I remember struggling to spin out even on steep declines hitting almost 30mph. Seemed a bit pointless to me, as even a small pot hole going that speed with 16" wheels is going to very bad news. Anyway there's far too many hills round here so swapped the chainring for 44T and it's much more usable now as can take on more hills. Spins out lower mph now, 22-24mph which is fine with me as I'd rather freewheel downhill and rest my legs. If I wanted a speed machine I'd get a road bike.

What a workout! I would've left my lungs right there at the side of the road. I ADORE my 6 gears. I even opted for the 44T chainring after trying the standard 50T for about 3 months. Live in Mexico City, and the streets are not in the best shape. There are also a lot of underpasses, overpasses, and some long roads that do not appear to be uphill BUT THEY ARE! Since I'm not in the best of physical shape either, so the 6 speeds are a MUST for me. And a good, resistant set of tires.

Thanks for another great video. My wife and I (early seniors) have had 6 speed 44T Bromptons for 13 years. Mine was the super light while hers was a standard steel frame and forks. The 6 speeds allowed us to climb most hills and we rarely spun out in top gear. More recently we were fortunate to purchase two t-line urban bikes and the weight and gearing difference has been remarkable. We can easily spin out in top gear --due to the reduced weight and while we miss the lower gear on some quite steep hills the reduced weight makes all the difference. We can climb as easily as with the 6 speeds. So admitting riding a t-line is incredible and still quite rare, we find the 4 speed gearing more than adequate for cycling distances of 50km or more. Perhaps the biggest change is remembering there is only gear changing on the right side of the handle bars. Our next test will be to do some gentle touring to see if 4 speeds on a T-line are fine to tour with. We expect so.

I once had a try-ride on a 2-speed across Waterloo Bridge when Evans of Waterloo lent me one, and it was seriously quick in terms of acceleration. But it is probably best left to urban flat areas. But, put it this way, I once outran the Metropolitan Police bicycle cops on Waterloo Bridge without even knowing they were chasing me when I was on my 6-speed after I ran a red light at 7:30am on an empty road (they were hiding, bless them). I was riding a bit quick, but was totally unaware they were trying to catch me. They only caught me because I stopped for the next traffic lights at Aldwych. In summary, if you want to outrun the police without spinning out, the 6-speed is your man.

May 2017, I’m a commuter, it’s not a big distance but does have a medium hill. I wanted it as light as possible. I visited the Brompton shop in London and they allowed me to try some Bromptons out. Testing the 3 heights (I’m 5’8” and went for the highest, for a more upright ride, and wide seat, more comfy) Before going, I was all set to get the single speed ; lightest, trouble free, but I realised that an extra gear didn’t add much weight, and you have to have the chain tensioners anyway. The 3-speed hub felt inefficient and noisy and added weight, click click click, couldn’t live with that; so that was the 3 & 6 out the running. I went 2-speed: “Gearing - 2-speed, -18%” in superlite in fact. Been loving it ever since. 1st take off gear, going, hit 2. Perfect for me. Any faster I’d hurt myself more. The 4-speed wasn’t out when I was buying, I’d have been tempted with that I imagine.

Like yourself I’ve found it hard to spin out a 6 speed unless it’s down a steep hill. My Chpt3 is nicer to ride due to weight, and I prefer a traditional gear shift rather than a pause for hub gears. However my 2 speed is the easiest for a flat commute with a steep hill at the end… the 2 and 4 spin out easily. However as all Brompton’s they get twitchy at speed… so maybe that not a bad thing. Personally I’d go 4 speed or 2 speed for a commuter and a 6 for touring due to range of gears and not concerned of weight… a 10kg bike is a dream to carry over bridges in a Train station - where surprisingly an extra 2/3 kgs on a 6 speed makes a big difference!

I have a 6 speed with a 44 chainring, but to be honest, living in Buxton, Derbyshire, an even lower first gear would be more useful to me than a high top gear, as I just donder down hills and along the flats anyway, I'm in no rush nowadays. I know you mention maintenance as a potential issue regarding choosing a Brompton, but lets face it, even a six speed Brompton is ruggedly simple in cycling terms, and the worst thing that's ever happened to me is being stuck in a ratio.... I can live with that. My way of thinking is, as long as it's not massively over complicating things, or massively adding weight, it's far better to have another option, but not need it, rather than needing , or wanting it, but not having it.

Actually it's easy to mod a 2 speed for more gears. I wonder that would make a difference compared to the P line. Or is the P line also feel faster because it's lighter. I've heard from many people that the lightness of the T and P is felt at the initial acceleration from stop, but after that you can't feel it. Of course you can feel when lifting it. 2 speed with a 5 speed cassette and matching shifters. 11-21t ? dependent if you change the derailleur to handle a bigger cog.

The power pedals don't really help with anything other to see if you're doing the same effort, as for a given power, you're going to do the loop in exactly the same time, no matter what your gearing is (if you ignore the aerodynamic and weight differences). The three tests to do would be: 1. Max speed (for hardest gear) 2. Steepest hill you can get up (to see what the lowest gear does for you) 3. Standard deviation of cadence on a rolling route (to see what the jumps in numbers of gears makes a difference to). I admire your efforts, and your honesty in admitting the data didn't really help!

Just a note ~ I have two Bromptons, a 3 and a 6..., I travel for business and have carried both in air travel in or as gate-baggage (in a carry bag). My 3-speed is absolutely indestructible 😋 - my 6, not so much 😑. For around town etc, 6 would likely work wonderfully for you! I like to travel and take my bike with me - and stay a few days extra for the adventure of small touring etc., and the 3-speed is perfect for that - and no worries about the gears getting beaten up by the baggage handlers! 😎

Great Video. I have the 6spd with the 44T chainring. It feels like the second hardest gear is too hard, while the 3rd hardest gear is too soft for leisure riding on zero grade. I really miss the 3rd hardest gear when I had the 50T chainring on as it felt perfect for a leisure/0 grade ride. Can you please advise on which leisure gear you enjoy across all the spds / chainring options? Would make for a fantastic video! Cheers!

We have quite a few left 😀. So I’m sure there will be new around for a while and used for a long time 😀

In 2019, as a 72 old year pensioner, during high Covid19, I used an other vise closed down and free day to look for a Brompton for travel purposes. So it was only the "color" which was in question, when I bought my Top, yellow flame painted, black version, "SuperlightM6LXBrompton", with an M type stem post (which today is down to 9,35 kilo, and still with its mudguards)! I have used it going up a very steep serpentine hill, where I had to walk at times, even in the low gear! And going down again at top speed, and often having to brake fully down, to be able to pass the "cattle prevention bars", crossing the road. My Brompton never let me down! But on the other hand, would I expect even a 4 speed titanium bike, for a double price, to be as pleasing as mine? I will change my last bought lightweight parts, to give it, maybe

I have found out that the clamps holding the, original titanium stays on my bike are really "heavy metal" and I then found a set of similar "carbon clamps", with small black bolts, + two aluminum holders for the mudguards to hold them on the frame, from China. I advised the Brompton Factory to eventually do the same, as an easy measure to make the bike lighter from the Factory (I haven't had the time to actually change them, as I need to remove the wheels)? I have a carbon M handlebar to be changed from the original, as I have also done with most of the possible nuts, bolts and the security discs, some of the brake parts/bolts, into titanium. Also a titanium seat post and lightweight seat clamp. I expect to come below 9 kilo at a time, and then not so far above a 4 gear T line, with mudguards, as I have seen from a film on KZread, making his T line less heavy, from well over 8 kilo! Finn.

If it gets stolen I can’t replace it now and think the 4spd would be too limiting in hilly situations as it does not have the range - I tour quite a bit. So now all they leave me with is a standard all steel version if I want 6spd again.

@Sailing Sexy sure - thanks for your insight. Yes we all have our different needs and depends on the areas you cycle in. For example I cycle in places where there are hills so lower gearing on the way up and higher gearing in the way down with the 6spd helps out a lot. I just wish Brompton gave the option of both the 4spd and 6spd so we can choose. It is not just about lightness either - the Titanium forks and rear triangle gives you a better ride IMHO.

I enjoyed this due to your charming presentation, but it was neither a comparison, nor credible, since it was all about your legs. For all I know the 4 bikes might have differed in weight & chainrings & tires & pressure - none of that was laid out for apples to apples comparison. All that matters was the measurable & calculable, such as the 'gear inches' of each gear combo, which you omitted. It is titled, after all "gearing test".

The aftermarket and other trifold manufacturers offer derailleur gearing with 5- to 9-speed cassettes and IGHs with 3, 4, 5, 7, 8, 11 or 16 ratios. Compared to that, the factory offerings in your video seem...quaint.

The P Line is awesome with its lightness, so it feels like it accelerates so quickly! Looking forward to round 2 - just not sure how to do a better comparison!

Given: A. You can't max out the top of the 6-speed B. The lower end of its gear range is where it shines and C. The difference between the the 6- and 3-speed is only the the rear sprocket (13 and 16 sprockets for the 6-speed, 13 only for the 3-, with 50 teeth in front either way) Then why not the 3-speed but with a larger rear sprocket (or smaller front)? I have a 6-speed and basically never need to switch the 2-speed, left-hand shifter. By keeping the left shifter in "-" I find "1" on the right to be good for hills, "2" for starting and stopping and lower speed environments and the "3" the the maximum usable speed when I have a flat straightaway (just spinning out every time I try "+3"). I have knick named these "hill," "street" and "road" gears respectively. I cannot see a reason to change the left shifter to "+" (the 13-tooth rear sprocket) for any practical purpose. What say you fine Bromptoners?

@heuer73

Жыл бұрын

C: the difference is not only the sprockets. The hub is different as well. They use a wide range hub on the 6 speed, that means the gap between the gears are bigger and they compensate with the 2 sprockets.

I haven’t looked through your results but notice that you don’t talk about efficiency. The pure derailleur geared bikes will always be more efficient (about as close to 100% as you can get) across their whole gear range. The hub gears will be much lossier when not in the mid gear (which is very close to 1:1, i.e. not really a ‘gear’ as such). The top ratios of a hub gear are usually woefully lossy. As much as 15% of your pedalling effort is lost to friction inside the hub rather than propelling you down the road. That will make it commensurately harder to ‘spin out’ in top.
