It's a better, faster, funner scooter.  Ready for Maker Faire 2010!
Combining the front end of a mountain bike with the back end of a kick scooter makes a high performance scooter that is easy to ride.
The high wheel shape (aka penny farthing) hearkens back to the 1880s when big wheels ruled the roads.  They too were pursuing greater comfort and more speed.

Materials: 
Dumpster rescued items including: scooter, mountain bike front end, floor boards, spray paint.
Store bought items: 4 nuts and bolts, 2 grips, varnish, 3 feet of 1.5" steel tube

Step 1: Layout Using the RAD System (Reality Aided Design)

Reality Aided Design refers to laying the parts out and eyeballing the geometry.   (no software needed)  Here I'm setting up the basics of a scooter body behind a mountain bike front end.  The yardstick represents the steering axis (center of the head-tube).  Note the steering axis intersects the ground ahead of the front tire contact point on the road.  The tire contact point 'trails" the steering axis.  As a side note to bike designers... The bend of the fork blades produces "rake" aka "offset" that consumes part of the trail to shorten or snug-up the trail for a certain head angle and wheel diameter.
<p>I really wanna make this, but I don't have a welding torch, or the hydraulic press, so do you think it'd be safe to make the down-tube out of two 2x4's joined at an angle?</p>
That could work. Another way might be to join the straight metal down tube to a vertical 2x4 that is bolted between the riser plates of a Razor scooter deck. The joint could be by bolting through the down tube and 2x4. It may be tricky to make the joint strong. Another way to get welding is to cut and file your parts so they fit well and taking them to a muffler shop for a quick weld. They are good at welding thin walled steel tubing.<br>
<p>It is cool, and actually Kool Kat has made something similar to the mountain bike scooter. I still like it though, very interesting! </p>
Epic! :D Too bad I don't have half of the things to make this... :(
I looked at the picture again and I realized that the scooter has a handbrake! No having to stop with your foot!
I see what you did there.... its a bikescooter!
<div>This is a great Idea.&nbsp;I have all wood working skills and little experience with metal, but I just got an ARC welder and a gas torch welder so I think I will test my skill on a smaller version of this for my kids.&nbsp;That way if it falls apart they get hurt not me. &nbsp;</div>
Hah! So wrong...
my dad made 2 of these about 6 years ago for my brothers. sorry to say, but somebody else has created these before you. glad to see that somebody else is creative enough in a country losing common sense over crazed consumerism and fear. I am sooooooooooooooooooooooooooooooooooooooooooooooooooooo glad that maker fair and instructables exist!!!!!!!!!!!!!!!!!!!
Don't be sorry. Great minds think alike. I've been making them since 2004 and bringing them to all 7 years of Bay Area Maker Faire to inspire folks to create fun vehicles. Happy making.
people should use RAD more often
I like your bike, very original, &iexcl;congratulations!
i have been using a commercial kick bike for the lat couple years.<br>front tire is 700c-35, The rear is 355x40.<br>It is a much harder workout compared to biking, especially in urban areas, where you need to stop every block for cross traffic on a bike.<br>my heart rate is much higher , than on my recombents. Usuallt around 130 plus on the flats without really pushing it when using the kick bike.<br>they make all kinds, so imagination and terrain is the key. serious off-road ones with higher clearance and beefier set ups. Racing types that , are super lightweight.,with fast tires, The first time i met a guy with one he had kicked to s place called bear mountain from central park,NY . 100 miles round trip, and far from flat. A lot of nordic skiers and ultra marathoner use them. <br>The nice think about this set-up. is the size and big front wheel , prevent you from do a header in a pot hole or when you catch the plate on a tar heave on city streets
So..., you reckon the pun is mightier than the (chop)saw??? ;)
Nice for paved surfaces.&nbsp; Now you need to put a full size wheel on the back (or at least a larger one) and improve the ground clearance slightly.&nbsp; The Amish around here (mostly the younger ones) use kick bikes with full size wheels front and back.&nbsp; They work on country roads and even down farm lanes.&nbsp;&nbsp; I guess pneumatic tires are alright but they interpret the Bible to say chains and gears are a no-no.&nbsp; They look like fun.&nbsp; You can buy them but they probably make their own. &nbsp; &nbsp; &nbsp;
Flat ground speed tops out at around 12-14 mph based on my fitness.&nbsp; Uphill has not been attempted by me, but I imagine it's slow (same cadence shorter glides).&nbsp; Down hill speed only limited by slope and courage up to same speed as a bike.<br /> It feels like more workout per mile than a bicycle and somewhat slower at same effort level.&nbsp; Hundreds of people enjoyed riding it at Maker Faire.&nbsp; <br />
I'm sure it's more of a workout than a geared bicycle, but the Amish and Mennonites are farm boys--they're tough.&nbsp; It still all looks like great low-tech fun!&nbsp; I'm also sure everyone who rode enjoyed it.&nbsp; Keep gliding, Woodenbikes!<br />
Saw an Amish girl using one the other day.
this is realy COOL!!!!!!!!! im planning on making one myself.
one word... amazing! im gonna try to get my grandpa to help me make one. great job!
Outstanding! I really like this. Questions: what speeds can be attained?; how is it going up hill?&nbsp; is it stable?; would it work as a &quot;replacement&quot; for a bicycle?&nbsp; Enough, I know.&nbsp; Good luck in the contest! Cman<br />
&nbsp;I love this! I could probably make one...if I knew how to weld.
Once you get your wire feed welder set to the right speed and temp welding is as easy as coloring <br />
--- WITH HIGH VOLTAGE AND MOLTEN METAL!<br />
&nbsp;high amps not volts a wire feeder won't ever get over 30 volts<br /> <br />
my bad it was late when i wrote that<br /> <br />
Haha, I like that that makes it better... Its got a low PD so its <em>fine</em>. Doesn't matter that its the Current that'll kill ya :P<br />
Find an older style bike with a swooping bottom bar and cut at the hub, run the bottom piece through the scooter body... <br /> <br /> I think this could be even better combined with an electric hub for some shenanigans...&nbsp;
These are commercially availible here in Australia&nbsp;
Nice!!!!!!!!!!!!!<br />
Very nice! Would it be possible to flip the steering head around to lessen the reach? <br />
<p>That's an easy thing to do with most stems, and I've done it on another bike.&nbsp; (The stem connects the handlebar to the steering tube.)&nbsp;&nbsp; This particular stem has the complication of the front brake cable running through it.&nbsp; so I may just swap in bent handlebars from an old 3 speed bike where the grips are moved back closer to the rider.</p>
Very thorough and concise. Especially the part about the actual bending of the tubes and more importantly, what exactly was used. Mostly all other Instructables that show you how to construct or modify a bike or other steel tubed vehicle so nonchalantly skip that part, which in my opinion, is the most important part. I for one applaud and celebrate your Instructable.<br />
Tres nifty. Very nice project, and very well documented.
Very nice project. I just love it.<br />
Neat! now all you need is one of the front wheel hub electric bike motors and instant &quot;mountain bike ELECTRIC Scooter&quot;!<br />
Very cool project, and excellent writeup!&nbsp; Breaking things out into so many steps is a great way to help users stay on track.<br />
