Any ideas on making a tricycle? They're impossible/expensive to buy in Ireland and I wobble with shopping on my bike!

I don't do many miles in my car and hate using it for the four mile round trip to the village shop for green reasons but I'm in a very hilly area of South Co. Sligo (north-west part of the Republic of Ireland) and even using baskets on the front and back of my bike, it's positively scarey! Any ideas on, for instance, using two old bikes to make one tricycle? Thanks!

converting a bike to a trike?

Anyone have info on converting a bike to a trike? My disabled son has balance issues but wants to ride with the family, however we can't afford a new adult tricycle or one of the expensive conversion kits. He's much too large for training wheels to work. I'm hoping to find a way to convert an old bike with minimal expense and no welding.

How do i make a tricycle move on a track with battery power?

I do not know anything about engineering, but I want to make a tricycle move, by battery driven motor, on a track. We are thinking that something along the lines of a childs battery operated ride on train would be the route to go and it includes a decent size track, but are unsure if there is a better, cheaper, or easier way that we should do this. No, this is not for a child, it is for a halloween decoration. Any relatively simple answers or a point in the right direction would be helpful.

Feasibility of an eddy current difficulty brake on a tricycle.

Hello all,  I'm a biomedical engineering student in Canada, and I'm working with a doctor to develop a training tricycle for children with cerebral palsy. One of the issues we'd like to solve is that since the tricycles are not geared, some children are simply too good at pedalling on flat surfaces and don't get the necessary muscular workout in their legs from pedalling.  We'd like to add some sort of difficulty setting to the rear wheels of the tricycle (the front wheel is occupied by a locking mechanism we designed) to make pedalling a little more challenging for some kids. I considered using a friction system but the idea of adjusting tension in two breaks simultaneously and the frequent pad replacements doesn't appeal to me.  I recently thought of using eddy currents to slow the rear wheels. This would be extremely convenient because we could control the eddy currents in function of the child's strength to give them each a personalised workout. My questions are : Do you think it's feasible to use eddy currents to adjust the difficulty of pedalling a tricycle by slowing the rear wheels? Could an electromagnetic system be used with a sufficiently large battery to allow a child to ride throughout a day? Would a system with swapable permanent magnets be more efficient (similar to a power tool)? Would an eddy brake system produce excessive heat that could in turn harm the child?  Thank you for all your help as I'm not an electrical engineer.

Kite-Biking? Street Luge Meets Kite Boarding Meets Tricycles

(WARNING: If I or anyone else should try this or try to recreate the idea in any way, please be safe, wear full body racing gear Like for motorcycles and such. If I do this I will definitely try to be as safe as possible.)Okay so I was fooling around on the net and ran into Turbo Pro Tricycles. http://www.primepedalkarts.com/resources/2007picturboyellowbig.jpghttp://www.primepedalkarts.com/turboproyellow.html They have a Demo Video that's about 20mb if you'd like to see some action with it. Anyway, as soon as I SAW the Trikes, I was thinking EXTREME. Basically the bikes steer like Luge boards, except you pedal them to make them go, not gravity. Well The bikes have a 'Free' gear which is used for coasting, and I was thinking with some modding, This could be an ATV or street beast (Permitted that these would be allowed in your area). Just add a Kite and steering system with the mandatory trike mods to follow (A list at the bottom) and you'd have a new (I hope) extreme sport 'KiteTriking'. I'd keep the pedals functional if possible so that when not skirting around on Kite-power you can pedal around. Although a completely other idea might be to try to motorize it electrically. (someone come up with a concept?)The mod list would most likely have to include:Some appropriately sized metal alloy wheels with racing or All-terrain tires to match.A reinforced chain or complete replacement.Brake replacements or modding to make them more efficient.Adding an Emergency Break.Reinforcing the frame.Changing the seat to a more sturdy, ergonomic one.And changing the pedals to aluminum ones.Kite mounting and emergency release mechanism.Some sort of rear storage space.

Electric Motor Tricycle 6V4.5Ah

I bought a riding toy for my son and it's cool, but it doesn't have enough power sometimes.  It's fast enough in the house, but it gets stuck outside.  The plastic wheels tend to slip on rough surfaces and inclines, but I can address that issue at the wheels/tires to some degree.  However, the battery that came with it is a 6V4.5AH/20HR sealed lead-acid rechargeable battery (It has F1 contacts, so unless I change or adapt the wires/connectors, I think I need to stick with a battery that has these).  The AC-DC adapter has 6V DC 500mA output, but I think I could get a UNIVERSAL AC DC ADAPTER {1.5V 3V 4.5V 6V 9V 12V 500mA} that would work with a new battery. I'm hoping that I can increase the power noticeably but safely.  One constraint is the width of the battery area inside the "engine" compartment.  It fits the present battery (1.75 x 2.75 x 4), but I'll have to mod the compartment to fit a replacement that's more than slightly bigger. I've seen some 12V4.5AH batteries online, but most are larger in every dimension. Am I even on the right track thinking a higher voltage battery is what I need?  Could I use an NiMH or Li battery/batteries instead? What's the easiest, safest, cheapest route for this mod? Thanks, Dan

i would like to creat a large steam engine, big enough to power a vehicle made of bikes that seats 3.

The vehicle would be pedaled until some speed was reached, then the engine would be switched on. the bike contraption would consist of two bikes side by side, held together by lumber. two of the seats would be mounted in the bikes original seat holes, on the side, and the third would be in the middle, the driver. the front wheels of the side bikes would be removed and he front end of a third will be used in the front. the vehicle will be like a giant, steam powered tricycle. Other engine ideas, other than gas powered, would be greatly appreciated, the cheaper the better.

MIT Open-couseware Helps Physics Professor Become a Web Star

He is part of a new generation of academic stars who hold forth in cyberspace on their college Web sites and even, without charge, on iTunes U, which went up in May on Apple's iTunes Store.In his lectures at ocw.mit.edu, Professor Lewin beats a student with cat fur to demonstrate electrostatics.

Hydraulic drive for trike.? Answered

I am in the (long term) process of rebuilding my tricycle recumbent bike (a tadpole configuration). At present it has the usual long chain driving the rear wheel. I would like to do away with the long chain for several reasons and am toying with the idea of using a hydraulic drive. Cylinders at front and rear with the front driven by my feet and the rear driving a standard pedal set with the normal short chain/gear set - in face the rear frame of a standard bike with the hydraulics rams in place of my legs.. I can't find anywhere that this has been done and this worries me as generally what can be done is done. In metal weight would be a problem but I hope to be able to machine the rams in plastic tubing giving me a light energy transfer from front to back. Hopefully it will be electric assist as well but that is another matter. Any comments would be welcome before I commit to building it so I can see why this is such a bad idea.

Bike to Trike - Bike Axle Replacement

Along with other minor changes to my bicycle, I really (really) want to turn my bike into a tricycle. I figure having one front wheel and two back wheels would be the best (and by best, I mean simplest) arrangement. I'm also guessing that it would be fairly easy and perhaps weld-free. I want to get metal tubing/a metal rod that is the same size as my back axle, have it be about 4 feet long, and place two wheels on either side. The gears would be located in the same spot they were, just attached to the axle and not the wheel. I don't know how thick my axle is, but I can figure that out - the problem is, will the axle hold my weight? I plan on also loading some cargo (add, say, 50 pounds). I don't think the cost would be too much (over $50?) and should I need to weld something, my brother might still be able to do it. Do y'all think this would work? Would the axle hold 250 pounds of weight? If so, the axle could be threaded on the ends so as to keep the wheels in place, right? Thanks!

Davison and being an inventor

Last week a company called Davison was running targeted ads on Instructables through Google Adsense. Google Adsense typically places contextual-based ads on sites making connections between advertisers and publishers based on their search technology. However, advertisers can also work with Google to directly placed ads on specific sites. At first, we were flattered that Davison chose to target us, and further flattered that they were actually using our terminology in their ads. You may have seen "Cool Instructable?" or "Have an Instructable?" text ads running in our right sidebar.After checking out what Davison does, I decided they weren't a good fit with us and removed the ads. Normally, this would be no big deal, but because of the business Davison is in and the specifics of this case, I wanted to share my thinking.Davison solicits ideas from independent inventors, creates prototypes, markets potential products to manufacturers and distributors, and collects royalties. This is not worlds different from what we did at Squid Labs, except I would characterize Squid's activities as more technical and with the aim of creating sustainable businesses rather than exclusively creating products to be licensed.The rub comes in that Davison is not forthcoming with how they actually make money: high fees paid by the independent inventors. Here's a Forbes article that goes into greater depth, but for me, the important statistic is this: 37,000 or so people have contracted Davison Design's services in the last five years; but only eight of those who have signed up have realized royalties exceeding their fees to Davison.A 0.02% success rate is just awful, and clearly shows that they are preying upon people who don't know any better.The thing that personally put me over the edge was a section from their Questions and Myths:9. Can I tell people about my idea? We recommend that you do not publicly disclose your invention/idea to anyone (not even a friend or a family member), unless you have confidential documents in place to verify that you are the originator of the invention.Obviously, I have a conflict of interest, because I want you to share your initial ideas here in the forums and how you built your ideas into prototypes as Instructables to help me grow the site; however, the concept of absolute secrecy is anathema to me. Here at Squid Labs, we know of no one that has had their invention stolen by some big corporation (more on this at Saul's column in Makezine Vol. 9; full text available as an attached PDF, kindly permitted by Make). My experience has uniformly been that sharing yields stronger results than hiding. The person you share your ideas with might turn into a business partner and be instrumental in your shared success.Clearly there's demand for services to help inventors. Davison seems to have a nice facility at Invention Land; instead, why don't they invite the almost 8000 people per year that contact them to attend an "invention boot camp?" Attendees could learn some basic design, CAD, and machining skills, give mock presentations, and learn how to do a preliminary patent search. If Davison was doing a good job, they would start to see some success from their graduates, and companies looking for innovation would seek out the graduates or ask to attend the camp's final design reviews.Teaching people all these skills might sound impossible - like a full undergraduate and graduate series of degrees compressed into an 80-hour crash course. No course can cover everything- instead, it should give motivated people the basic skills and confidence to start doing it themselves, and teach them how to seek out the additional knowledge they need. It's surprising what motivated people can accomplish if you just get them started.In 2002 Saul and I taught a one-week class called Cyclomerisation where we taught a group of 12 people just enough bicycle design, CAD, and manufacturing to make them dangerous. Each person then designed their own custom bicycle using 8020 extruded aluminum and jet-machined connectors. We had telescoping unicycles, recumbent tricycles, and plenty of standard bikes; for example, check out Saul's 8020 Chopper. Half the participants were MIT students, half were not, and it made no difference -- everyone was motivated to learn something new and to put it into practice.If this idea isn't Davison's thing, then maybe I've found a project to work on after Instructables can run itself. In the meantime, I'm sharing the idea with all of you, because that's the best way to vet it, see if it has legs, and make it stronger.More pictures from Cyclomerisation here and here.
