🤔What is the biggest mistake you've made when buying a bike? Let us know 👇

99% of riders don't have access to this tech. 😐😐

Correction: 99% of cyclists do not have access to this machine. A bike fitting should be included with the price of a bike and be offered in every bike shop for every bike.

You guys have done quite a few bike fit videos from varying fitters, and now AI. I’d really like to see you get a bike fit done by 3 or 4 reputable fitters and compare numbers, and then at the end, put them all in a room and have them explain what they see vs another. If possible, all in same day, to rule out any day to day changes that happen.

In Sydney, Australia the store that has this idmatch system costs $450 for a fit. Unfortunately that’s a lot of money that could be spent on an actual bike.

As a professional bikefitter, we have been preaching the gospel of fit first, buy later for decades. I like your selle italia electronic bike but I’m still not quite sure what the AI is doing. I haven’t read all the comments, but did anyone mention that the fitting machine didn’t even have brake hoods! Unless you’re a track cyclist, the primary hand position should be a the hoods/brake levers. The fitting machine should also have telescoping handlebars to determine ideal handlebar width and adjustable crank arm lengths. Ollie also needs a wider stance width on his left foot as I’ve noticed his knee tracks laterally on that side on previous GCN videos. But great that you finally mentioned this concept that riders should fit first and buy second as it does save money in the long run.

So basically, this is an advert with a clickbait title. Besides, it seems like many of the comments are bought.

Bike fit while only riding in the drops? How does that make any sense when one spends at least 80% of time on the hoods…. I thought the bar would be changed for a bar with hoods for the more endurance position but nope… Machine learning can be a great tool, but you have to ask the right question….

My custom made travel bike has been constructed after I had been measured on one of these fitting machines; however that was a long time ago and they weren't that higtech at the time. My bike fits me like a glove.

system tells oli that he needs a 57.5, yet he's been riding a 56 all this time, presumably with no issues... makes you think

A physiotherapist specialist bike fit was brilliant for me. Changed my saddle to pedal dynamics and my reach and stack height to get rid of some lingering pain and power transfer losses.

I think that the key point is to consider getting a pro bike fit that uses an adjustable bike-emulation machine before buying a bike. Both my wife and I are in the middle of a fitting where the fitter used mechanical device, similar in concept to the one in the video but with manual dials and levers, to dial it to fit our dimensions. He also used devices to measure our sit bones and shoe sizes. So this cost $200 each (was $150 last year), and the conclusion was that we both had bought bikes that were too big. My wife found her entry-level Specialized gravel bike to be too uncomfortable to ride more than 10 miles, but after getting new handle bars, stem, grips, and a seat with proper set up she is now riding without pain. Perhaps investing in a bike fit first could have saved us the extra $400 in new bike parts for her $750 bike. Still waiting on parts for my road bike…

Great stuff! Unfortunately, until such tech (or similar) becomes a standard in every bike shop (for free or with minimal charge), it remains only an interesting curiosity to me.

I wish manufacturers let you pick your components a la carte. I fit a size 58 Trek Domane and had to swap out the handlebars for 40cm ( stock was 44) and am planning on getting shorter cranks eventually ( Stock is 175mm). I should have been able to make those choices at time of purchase, at a minimum with the same component level, possibly same or optional upgrade to a higher level, and then they could assemble my bike.

With two herniated discs in my lower back, I HAVE to get an endurance position and then some, plus I run slightly shorter cranks too. No flush stems for me anymore.

Since the bottom bracket is a fixed point you can alter all the other stuffs but you have to keep in mind that they are all levers so even small increase/decrease can make a difference in how the bike feels. A bigger frame with a shorter stem can have, theoretically, the same meseaures of a smaller frame with a longer stem but the riding experience will be different.

Which is exactly why I went to Vires. Every other bike I looked at would’ve needed some adjustment and that’s not cheap these days with one piece bar/stems. Recommended.

I appreciate that for the endurance fit it raised your handlebar without shortening the reach. Most riders can manage sitting a little bit higher without having to scrunch their spinal columns.

Years ago, I went through a similar process at my local bike fitter before selecting my bike. They steered me toward a frame geometry from a brand that suited my unconventional short crank requirements. The setup involved just a basic looking fit bike and some video motion capture, yet it proved to be effective.

I am a heavy rider and because of that, I can't fit like the typical rider. However, that doesn't stop me from riding. I tend to stay away from carbon because most have weight limits that I don't meet, but as far as geometry, what I tend to do is get a bike with an uncut fork, a high rise stem usually somewhere around 17 degrees, as well as putting spacers under the stem. I do not use all in one stem/bars as I am not in that market and I would be better served by loosing 10lbs than spending that kind of $$. Also, depending on the bike, I may also choose a seatpost with some layback. I have also been tinkering with cranks that are a tad shorter than ships with the bikes. I have been opting for 170 or 165 and these help keep my knees out of my stomach which helps a lot. Now, I know I am not your typical cyclist, but if anyone is having these issues you may want to try some of these solutions. The idea of having a long reach with a higher stack height is not new to me, it is something I have been doing for more than a decade now and am very comfortable with.

I'm nominally a 54 on a bike with more relaxed geometry but I also fit a 56 with a more aggressive geometry. Long torso allows me to adopt a lower position. It would be nice if you could swap out fit components (stem, handlebar width, saddle, crank length) at the time of bike purchase with like components at no extra cost so you aren't forced into buying a bike package that doesn't fit you from the start. It'd save the average consumer money and trouble later on. I'm aware custom builds exist (Trek Project One $$$) but I'd like that option on a workhorse alloy 105 bike.

Being stupidly tall (2.03m), it's surprisingly easy to choose a bike: "I'll just take the biggest bike you have, thanks!" In all seriousness, a lot of manufacturers (cough cough Ribble, cough cough) build really small bikes and XL is only 58cm fitting folk up to 190cm. It's pretty annoying.

The jig not lighting up like a Tron Lightcycle irritated me more than it should! Ending up with some bikes you can actually get and ride is so much better than just being given the measurements and left to figure it out for yourself

GCN for old folks like me who, over the years, have smashed bits of their bodies in biking accidents and other sports accidents, comfort is key. The only thing of interest to me on this video was the idea that raising a bike's stack should be kept separate from shortening the reach. With two head on collisions to my 'credit' my neck is jiggered. I will experiment with longer reach but raised stack in an endeavour to remove serious neck pain post 30 miles. Thanks John.

Selle Italia SLR Boost... legendary saddle. It came standard on my Canyon Aeroad and, 2,000 miles later, I've never ever thought about it. I mean, my body has never produced pain or pressure points pointing to the saddle.

Curious there are no hoods on the bar to be measured by...which would seem to be a much more normal/popular riding position.

Speaking of sizing... and knowing that GCN works closely with Canyon, I'd really love to see a video on proper sizing with their brand. I find their sizing recommendations really strange. For example, I'm 182cm and set my saddle heigh to 77.5cm. I recently borrowed a friend's large Grizl for about a week of riding in Tuscany and was super comfortable on it... but according to Canyon recommendations I should be on a medium, which I find confusing... and I'm now second guessing myself ;)

The handlebar on that expensive fitting rig doesn't have hoods? That seems like a major miss. Most of our riding is done on the hoods.

Nice idea. Then try getting the vendor of the $15,000 bike to adjust the standard stem or crank or… anything at all. Some manufacturer is going to win a lot of market share when they actually focus on the customer and fix that problem.

Very few brands give you any choice now on component changes. You get what you get or you have to pay the shop to get and install a replacement the right size.

2:00 I love that the motion capture appears to be an xBox Kinect sensor.

I actually love this idea. I'm sure it will work better and better and that's exactly what everybody needs before getting a bike - the bloody fit.

The big bike makers (eg Canyon, Trek, Spec'd etc) don't help themselves inasmuch as they offer no choice of stem, bar width, crank length etc on a new bike (even though car makers have allowed you to pick options like cody colour, trim colour etc for decades and this info was used to build the car). So because I didn't want to waste money on a new bike to find I had to change out the stem, bars and chainset as soon as I got it (a waste of money and my time), I just bought a good, second hand Colnago frame and built it up myself. But I didn't feel inclined to pay high prices to have to change out the kit I didn't want - the bike brands don't help themselves.

I am one of those people who is often in the middle of sizes. Most recent bike i went up, next time I'll definitely go down and adjust with a longer stem or seat adjustment if i need to

Didn’t Manon present this a few months ago?

My local bike shop does exactly that, although I don't know what tech they use. They start with a bike fit and then can tell you what models they have that would be good for you. I know bike fits make a big difference as in my case it stopped a shoulder and neck issue from being unbearable. Next 'serious' money bike I buy will be after a bike fit.

The very sad thing is that most bike manufacturers still sell race bikes with 42cm (and even 44cm) handlebars that you can swap but mostly at a price. The first thing I did was change my handlebar from 42cm to 38cm and throw a perfect bar tape in the bin (It shred in pieces just by removing it). If only bike manufacturers would build to order in the factory or leave the fine tuning to the shops...

Best fit i had was by Pete Matthews (master wheel builder) in the mid to late 80's when buying a new bike from him. He had had a jig built and the methodology was in principle the same, way ahead of his time. Had a few bikes from him, handbuilt and fitted like a Saville Row suit.

my height is 166cm. i rode on a frame of top tube at 505mm, seat tube at 450mm with a seatpost 25 degree offset, stem 90mm. i changed to a frame of shorter top tube at 496mm, seat tube 440mm, stem +-75mm, non-offset seatpost...overall length is about +-4cm shorter. vola! i m better off and did not feel overstretch! our body tends to lean much forward naturally and more energy efficient in pedalling when speeding up

I love how they've used an xbox kinect for this - truly amazing how we can use technology and innovation for more than its intended purpose.

The stupidity now a days where media influence on people is to get the smallest size frame & put the longest stem, this put a strain on the back & no possibility to raise the handlebar (quill stem was brilliant) coming from an off season & longer than necessary stem makes the bike handle like a dump truck. In the 80’s when I did track we go for the bigger size & no your jewels will not get banged up as you’re riding all the time not climbing down your bike, top tube length was more important than seat tube height. Guest what they still do this fitting on the track & Japan Keirin.

My bike fitter spent 2 hours assessing fitness, strength, flexibility and asymmetries before I got on the bike, 8ncluding teaching and practising a set of strength and stretching exercises to improve the situation. He also sees bike fit as an evolutionary process and the initial fee includes quarterly return visits to tweak position and exercises as you improve. There's a lot of great use of AI and I'm in the IT business, but it still needs to be in the hands of an experienced human who can assess these things that the AI can't measure.

iDMatch was awesome for me when I did it last year and I take the results with me for any bike I get set up for - Was ideal for when I did my dream build!

Will definately consider this when buying my first Pinarello Dogma!

Buy a Daccordi, i just got mine, 100% built to my size from scratch. I got it with Super record electronic derailers and get this rim brakes and i still have the thumb button. I didn't want disc, rim brakes easy maintenance. Cost? Less than a 1/3 of a brand new Cervelo R5. Daccordi is the last of Family made bikes in Italy.

Would happily go through this, but for the cost and distance - unless they fancy sponsoring me a visit?! 😁

My bike shops is small 3 generation family owned, they do have new fancy expensive bikes but also great used ones . But sadly no fitting computer machines, clerk just eyeballs your size he picks a bike and u test ride he adjusts, you ride and you pay when it feels right... Its a chillax place i look for reasons to stop by and browse see which bikes come and go

Bought an XL canyon ultimate CFR (at 6’3”, I need 830mm from the bb to top of saddle and 610mm from the nose of the saddle to the centre of the bars) For some reason canyon made the fit on those bikes much more hunched up. Having spent nearly 11k on the bike, had to spend another €500 on a saddle pillar with layback and a longer stem section. Very very unhappy with it.

I did one of those .. totally off any manual bike fit . Ended up hurting my knee . 6 months of poor knees

I can never find these wonderful tools in my neck of the woods. Montreal Canada.

This is all well and good, but manufacturers don't allow you to swap parts. You have to make the changes by purchasing wider saddle, longer/shorter stems etc after shelling out for your chosen bike.

The sizes come in 2cm jumps but there is enough adjustment on the bike to make it fit you perfectly. I do wish they'd change cranks lengths more though. 165 upto 52's, 170 on 54-56, 172.5 on 58-60 and 175 on 60+. We weren't designed to sit for hours on a bike, so there is actually no 'perfect' size.

I changed, my saddle, stem, peddles, drivetrain, and wheels and rims.

This happened to me. After riding it for two years, I went for a second bike fit, and it was clear my frame was too big. This resulted in a new stem, new seat and new seat-post. The result was great, but it's not perfect. I did, however, follow Cannondales size chart, but what am I to do? I couldn't test the bike properly as there were no local stockists. Moreover, supply chain issues were a nightmare when I bought my bike across all brands. So I based the size on my previous roadie which wasn't ideal either but I'd ridden it for years without too many issues. The result; I dropped 5K on a stunning bike that doesn't fit me perfectly, but with what I've done, fits me ok. It's not like I can go out and replace my frame for another SSE HiMod frame just like that. So like 99% of the rest of us, we're stuck in this conundrum.

I don’t see the point? How many of us have access to this IDMatch? Us mere mortals must trust our local bike shops to recommend the best bike, although sometimes the bike shop will say what they want to sell a bike.

I bike hills more often than flat ground. I’d want it at an angle of maybe 30degrees.. near the point where center of gravity makes the rear wheel almost a unicycle.. that’s where I need power, endurance , and balance at the various dimensions. A bigger bike without fixed feet gives you these.

57.5 recommended... but 56 can work. What if you want the smaller frame for lighter weight? It would be cool if you could enter optimization parameters, to sort of guide the selected bike based on niche desires.

Opinion from someone who had his bikefitting done with exactly this system, and works in the AI field. It is great, but: - Being AI accuracy is heavily based on the sample size. If only few stores still have them then it will grow quite slowly, undermining the self-improvement factor of the model. Still it can be great and this is the direction the industry should be going - There is an interesting feature that allows you to correct your position based on the pain you are currently feeling on certain areas on a 1-10 scale. On my end, it overcompensated knee pain quite much putting the seatpost so high I could lock the full leg when on the extended part of the movement, making me rock on the sides quite much. My feeling is that it still needs a bit of improvement especially when facing problematics that may not be bike-dependent but health-dependent - The human factor is still important: AI does not substitute the knowledge and experience of an attentive bikefitter. The person not once asked me how the position felt, not even after setting up the bike in the target position. He was actually surprised when I asked "can I try the bike" Bottom line: it is a powerful tool but only in the hands of competent personnel, with full awareness of the underlying model and with a background in sports-science. It's the minimum you can ask when paying €150-200+ for a bike-fit

I am 186cm, fairly proportioned arms/legs, and 90kg. From where I live, I have no access to such machine whatsoever & probably the cost of such bike-fit is much higher than I would plan to spend in comparison to my bike price budget (btw, was it mentioned how much this session costs, round figure?) so I ordered new bike on-line, based upon the measurements of previous bike and my bike-fit knowledge. So, same as Ollie, the previous was 56 and wanting more comfort (not much interested about high speeds or breaking power records) I choose 57 (Orbea Orca has L on 55, which I could get, for more aero/speed...) so now I find the reach a bit too long, I changed the stem to 1cm shorter. More or less, I got the same result as what the machine got for Ollie. Did I make the right decision? If not, this would be my mistake... !

I generally always have to change the Stem and Handlebars as they come with a 90 or 100mm stem and I run 120, and handlebars are 42 with a 80 to 90 reach, where I run a 40 and slightly shorter reach between 70 and 75.

Let's not get blinded by science. In the late 80s my chain-smoking Italian frame builder got me on an agricultural-looking jig and had me pedal a bit. He made some notes on the back of an envelope and built my frame. I've always used his measurements and now I'm 65. Never had an issue.

5Ft10 got a size small Canyon Grizl. Actually, it's a really good fit! Doesn't help being between 2 sizes

Got to love the motion capture is done with an Xbox 360 Kinect :-) very old school

The biggest mistake people make when buying a new bike is buying a NEW bike. There’s so many good bikes out there for a fraction of the price if you know where to look. I just bought a $12,000 specialized S works tarmac for 900 bucks fitted with zip 400s and it looks practically brand new. Only thing I did was change the bearings, which also looked perfect, and it rides like a dream

Doesn't convince me. People keep forgetting the human body is adaptable, not static in any way. You can get a fit in any way, shape or form but maybe 1 month later, depending if you get fitter or adapt to the position, everything could need a tweak. Selling a bike fit as a quick band-aid solution is dishonest.

If you already cycle the distances and can sit over the bike in the size you think, then you can feel everything yourself.

I don't have a very expensive bike but if I were to get one I would definitely have a pre-purchase bike fit to give me the right parameters to aim for.

Ollie did what most people do. Go for a size smaller with a long stem and slam it anyway because it looks cool. 😂

Great video. I would love to do that bike fit.

It'd be great if gcn did a accuracy comparison on online bike fit sites with physical fits like this. Unfortunately, I'm not in 0.0001% of gcn viewers that can afford a 'proper' fit. Having been off the bike for a few years, my old settings were causing serious discomfort. With an extra 4" around the waist and seriously unfit, I found an online site that took my new body size and existing bike then recommended changes. Have to say, it's been pretty accurate. Saved a millennia of time tweaking stuff myself. Not entirely discomfort free, but better by considerable degrees.

I wish that database was made publicly available (for a fee of course). There are only two idmatch locations I can find in Germany; both hours and hours from me :( As a 193cm tall rider; I'd love to know, in general terms, what the correct SuperSix size is for me.

yeah all well and good. I have some biomechanics training and experience on the bike. My feeling is that automated bike fitting produce weird results because the underlying algorithm is reflecting current point of view in the industry. The "AI" is basically leveraging a bigger database and returning a probable fit, based on many samples. I don't think there is a feedback loop about the long term success of the fit, because people are usually going to a different fitter if thery're not happy. I'm not surprised it suggests a bigger frame. It's acookie cutter approach. No matter how many metrics you're going to capture, if the underlying assumptions are limited, the results will be unsatisfactory. The fitting is done on handleabars without the shifters which bitered me. I know you can adjust for that, but it changes a lot how you interact with the handlebars and the position. Again, not surprised that the system suggested a bigger frame. My fit is optimised for riding on the hoods first and foremost. BTW, I love my Selle Italis SLR boost saddles too. I'm 177 cm and ride road bikes (if you look at traditional geometry) with 53 top tube, 11 cm stem + 7 cm reach bar, zero offset saddle and 165 mm cranks. I also slam my stem, because of my monkey arms. I tried bigger frames, I can ride them okay, but all feel like riding a barn door. Much less agility, weight balance is off, and my position relative to the pedals is less optimal. Whatever bike charts suggest is between 54 or 57, too big.

Me and my wife tried idmatch. It’s ok and not as great as you guys keep saying. If there is leg length issue this system is useless.

I bought a Trek Domane in 54 cm, and always felt uncomfortable riding it. Swapped to an 80 mm stem, and 170mm cranks and the bike is much better now. The relaxed geometry helps. I purchased a Madone the next year in size 52 cm, and it fits like a dream.

The fitting bike doesn't have brake hoods, which is where most of us spend our time. So how can you get an accurate fit?🤔

Bike fitting make sense if you can ride at least an hour on that machine, since biomechanical issues surface after different time in different individuals due to the body ability to compensate before serious pain appear.

1. AI is machine learning. AI is just a marketing term. AI knows nothing. 2. Sure, the fit works for those near the mean, but what about atypical fits? 3. What is an "optimal road bike" position? There is no such thing. Optimal is a function of rider preferences and what a rider wants to do. Optimal is a subjective choice based on arbitrary criteria. You guys make some interesting claims in your tech....er...."promotional" videos.

Does this mean that the earliest users of this system did not get a proper fit, since the machine had a lot of learning to do?

this is really cool and all and i get that instead of paying so much in parts to replace and all that you can pay for a one time fit to find out but i feel like people dont get how expensive this would be. its around 300 dollars for the fit itself and i can imagine its not everywhere, so you'd also have to pay to travel to wherever you can get an idmatch bike fit. it just makes it kinda hard to justify it when i could probably get it done for much cheaper

In the US, you may have to make a road trip to find one, but for a few hundred bucks (~$300), totally worth it. Next, you have to convince your bike shop to set up the bike the way you want it. 🤨

Attention still needs to be made to cleat position which isn't covered by this machine Plus overall biomechanics, strength and flexibility which change over time due to training and detraining.

MY FIRST BIKE FIT WAS A COMPLETE JOKE, WITH ALL WRONG SIZING! I WENT TO FOUR OFFICIAL COLNAGO DEALERS, AND AN INDEPENDENT DEALER OF 40 YEARS WHO ALL SAID I WAS A 58s, YET I AM A 56s! I WENT TO SOMEONE WHO HAS DONE LOADS OF FITTINGS, WHO FOUND MY PROBLEMS STRAIGHT AWAY! THE BIKE WAS TOO BIG, WITH TOP TUBE TOO LONG, WITH BARS TOO WIDE, SO I HAD TO GET A SHORT 80CM STEM, WITH A 38CM BARS. AS I AM TALL, WITH A NARROW SHOULDERS, THERE WAS NOT MUCH CHOICE IN CARBON BARS, BUT MY BIKE FITTER SPOKE TO HIS GCN MECHANIC FRIEND WHO SAID ENVE! IT COST NEARLY £800 FOR BARS & STEM, BUT WORTH IT! I HAVE HAD TWO MORE FITS WHICH HAVE BEEN SORTED WITHOUT ANY PROBLEMS ON TWO BIANCHI BIKES!

If bike shop owners actually cared for the people to get the right fit for the buyer they’d offer a bike fit that was inexpensive. My old bike shop used to charge $200 unless you bought a bike from them then it was $150. I’m pretty sure if they charged $50 they’d get more business.

I did find it insightful. Thank you!

I went by the local dealer today to have a look on a Trek Domane AL2 as its on sale right now for 5699Dkk. Its a very budget road bike but I just think it looks great and its a great value fitness road bike. They had a demo bike in size medium I could try, im between large and xl in frames but what the heck, went for a ride, sat like shit, asked them to get a size L and XL home for me to try, they wouldnt. I had to buy it online for them to take it home because its such a cheap bike, atleast for them it is. So I drove home on my old GT outpost trail.. Right by another shop.. Trek FX1 in the window on sale for 3299Dkk, went in, size large in stock, looked at it, thought 'okay im not gonna bother with bikefit on another road bike again like the trek domane al2, its gonna cost me almost as much as the bike', bought a FX1 for me and a FX1 stagger for my girlfriend, set the sadle height and ride.. Lovely ❤

“Tell me that you’re sponsored by Selle Italia without telling me that you’re sponsored by Selle Italia.” My nearest place charges $500 for this bike fit, and I will come out with numbers I still need to figure out to match what’s on the market. That’s a lot of money. And I still might need to get a professional fit on my bike to get all of the parts dialed in.

Good thing I got an xbox kinect at home too so I can mocap my movements while on the wahoo trainer.

Im 5ft 11.5" & both of if my road bikes are 56cm frames, although one if them has a longer stem, but i dont tend to ride that one on my longer rides, so it suits shorter 1-2 hour blasts around the local lanes.

I am finding it hard to know the difference sizes. For example, bike sizing is different from the UK and USA according to many articles. I also have been informed by many conversations and articles that due to the geometry, you need the size down for a TT bike from your road bike. I.e. of you ride a Medium you will require a Small framed TT bike. Please advise me further. Would appreciate GCN answering these questions on the Tech Show. Thanks in advance to all.

300 pounds for saying which size is fit for you? And after it another one for real fitter for fitting your actual bike which should you fit perfectly but for sure will not on factory setup. This scares me, yet I understand how crucial it is.

Like a lot of GCN videos, 99% of us don't have access to this fitting technology.

Very cool system. I like how Italy has a million and one places with this machine, UK has a few, and all of the US has 5 or so lol.

Great to see the xbox one connect still getting used. Crap for gaming, but has/had so many other uses.

Canyon advert & Selle italia advert in a oner , nice one. Love it. Bike shops selling the size they have in house/in stock needs to be talked about.

Very interesting Ollie, always informative. I'm off to Google the price now.

Thanks Dr O and crew...yeah , aint nobody got one !! I bet everybody would do this , if it were affordable and convenient . Yeah....knowledge is power.

Only 8 locations in all of the US and Canada, so the cost of the fitting plus round trip airfare

i bought a Canyon. they suggested a M. Which i got. I then adjusted all the components to feel comfy. cant be any more difficult than that --also makes sense to raise stack for a longer ride. That what my brain would think. You never said how much it costs to get a bike fit. also id have to throw in airfare from vancouver and hotel.

I’d select the Pinarello too, then they’d give me the bill and I’d walk out with a Carrera. Love watching this kind of content because we all dream of having our dream bike.

That system wouldn't be any good for my high end bike when it is a recumbent bike. Take a look at the HP Velotechnik Grasshopper FX with Neodrives Z20 motor and Pinion 12 speed gearbox. Its a good fit for me with no pains from pressure on the wrists, backache or saddle sore. Mine includes a Ventisit cushioned backrest for ultimate comfort with the Bodylink seat.
