I like it.

I've got a flat bar road bike, which I prefered over drops, and there are times when I want to push it and other times I want to relax and enjoy the scenery. I think your stem could help me do that and, as such, has a lot of promise.

I hope to see it in stores or on sale one day--good luck!

I think it's a promising product. Couple of things on "popularity". Nobody likes to add weights. How much extra weight does the bar imposes? What are your target demographic (obviously not low end bicycle market). Once you narrow down the size of market, it does get smaller rather rapidly at which point you need to find out how much you can produce in a batch in reasonable manner. I am guessing that $275 or something probably was doing basically one off on very small run production vs say 1000 in a batch probably can get it down to $25-$50 range depending on where you make it manufactured.
Here is a thought. I see good potential in high -mid end MTB, Hybrid. I actually see even more potential on a market where being adjustability and being able to do so on fly is godsend. Folding bicycle market. Lot of folding bikes are somewhat limited in bar selection or folded size due to it's need to fold. This could actually assist both in fit/folding side of story.
Good luck to you. (I would love to try but my folding bike doesn't have standard stem -_-)
Probably can be good money by contacting company like Dahon?

Yah, I'd definitely try one & give you honest feedback. Lket me know what info, etc you need & I can pm you.

The rider presses on two lever accuators. They release the locking gas springs.

Thanks, That's exactly what I designed it for.

Thanks for the input. I really appreciate it.

If you're willing to ship one to England I'll see if my LBS would be interested. I mentioned it to them today and the guy sounded intrigued.

Yeah, but a lot of people don't use drop bars, either because they don't like them, or are intimidated by them, or even just don't want to spring for brifters. I know at least one person from occasional group rides who would benefit from a stem like this ... I don't know if the guy would actually pay for it, though.

To bikeguy55: How secure is the stem? You know what an articulated stem is, right? I have one on my road bike, and it creaks a little bit when I climb very steep ( around 20 % gradient ) hills out of the saddle. It's safe, in that it's not going to let go on me, but it's also very unnerving. Does yours do the same thing?

Get booth space at the Taipei Bike Trade show, Taiwan.
then bring your prototypes and prospectus there.
that is where the bicycle industry investment and manufacturing is,
that's why so much of it , bike stuff, comes from there.

Hey I would really love to try this out and I live in Lincoln so you wouldn't even have to ship it to me. =) I am not too concerned about adding weight if it works well and not too expensive. Being able to adjust the bars while riding would be really handy.

I see one length, quite long..
part of sizing a bike to the rider is having a variety of extension lengths

Softride suspension stems were 130 to 150 mm long , required the length to make the mech work.

But the customer was limited to a certain size. big people or with with long torsos

If there is someone needing a shorter stem they are out of luck, like the 51% of the population

Women.

I'd be willing to install one on my commuter bike.

Same here. Seems like a really good idea if it's not overly heavy. I would think it would be great for touring as well.

Looks like an interesting idea. Any idea how it would work with trekking/ butterfly bars. I have those and use am old school adjustable stem, but would be very interested in trying one out some day.

I designed it for my threadless headset but made an adapter for a friend so he could use it on his threaded steerers

The EZRIDE System retrofits to most any bicycle. It will work on any bicycle that has threaded or threadless headset. It takes 20-30 mins to install. So far I have them on a "Big Dummy" a Univega Hybrid, a Spealized Elite, and a Trek Hybrid.

I designed this one to fit me. I have received some feedback that the stem lenght needs to be shorter for most people. The first on I made was shorter but the longer one fits me better.

Yes, Give me a call 402-770-3501 Jon

I designed it to hold up to the rigors of bike riding so it is a little heavy. 3-4 pounds now and when I switch to forged parts it drops to 2-3 lbs.

Lets keep in touch. I will build more up over the holiday break so maybe I can send you one. What type of riding do you do? How often, etc...?

I have a fingerprint reader for my garage door. Best cycling accessory I've bought in a while

I am alway skeptical of new products but this looks rather interesting and if it was well made and remained solidly fixed in place after adjustments I can see it having many practical uses.

I am involved in the bicycle business at many levels, I run a small shop, work in a larger one as a builder, fabricator, and mechanic, and am looking to carry new products at a new location with a focus on local and North American made products.

And if you want to see this tested at -30C to see how it works... I can do that.

If anything, post up some detailed shots so we can get a better look at this.

Looks like it keeps the bars at the same angle (that is, same angle to the ground; "level" is always "level", etc) wherever you set the height:
http://www.JLSDESIGNWORKS.com/testimonials.html

Yes, That is correct. That way your hands do not ever move from the grips. The shifter and brakes are always in the same position relative to your hands.
Also, the light stays pointed at the same position through the range of movement.

I'll be damned! This could potentially be great for touring cyclists assuming it's reliable enough for long rides in any weather and doesn't compromise the handlebar strength like during steep climbs with heavy loads. When touring I sometimes wished I could adjust the handlebar height easily on the fly.

Unfortunately, I can't offer any business advice as I'm totally green in that area but the touring cyclists could be potential target market. When on the road for hours and days you encounter different road conditions and you energy levels vary greatly. Sometimes you want to go low for a fast descent, or stretch for climbing, or sit up straight during easy parts. Drop bars and touring bars solve that to some degree by offering multiple hand positions, but this invention of yours appears to have far greater range of positions.

Oh, and yeah, many people - including myself - don't like drop bars. I don't like brifters nor bar-end shifters as well as the "twisted" palm position on the drops. Something like this used with a flat bar or butterfly touring bars could be beneficial on long rides.

Oh, and rather than approaching major corporate manufacturers (they're more likely to turn you down, then develop something like that on their, market it poorly, then kill it and screw you in the process or they may be less open to radical inventions altogether) you might consider a manufacturer who caters to niche markets, cycling aficionados and geeks, touring cyclists. I don't know, something like Paul Components comes to mind. There was another, run by a father and a son that I can't remember, they machine small accessories for bikes.

That is one of the brilliant aspects of the design.

Thanks for the input.

One competing design is the Speedlifter http://www.rosebikes.co.uk/article/speedlifter-t-100

Yours looks better in operation and I presume doesn't require so engineering skills or a specialised tool and the services of a bike mechanic to install? As to looks I'd be changing the design for aesthetics, the gas struts look cool but the centre bracket is too chunky, makes everything look too heavy; a thin framework like a Moulton bike's space age frame or like clip on aero bars would look better.

Good input Thanks
