Mini Bike and Scooter Project Plans

Great collection of vintage plans to build mini bikes and scooters

PLAN 1

Build this mini-bike in your spare time in the garage. This little bike uses a large ATV-type tire in the rear, and therefore is suitable for off-road driving. Imagine getting around the woods quickly on the back of this scooter.

Using a small 2.5 hp engine, this project could drive around for hours on one tank of gas. It\'s a great hunting or scouting vehicle.

Most commonly, though, the mini-bike is fun for kids to tool around on! Check out these easy to build free mini bike plans.

For transportation across the wilds, you can\'t beat this mini bike. Its tiller engine sends it over rough terrain at speeds up to 10 m.p.h.—gets you to remote hunting and fishing sites ahead of your footsore companions.

An extendable rear rack takes your equipment load off your back, and carts clumsy-to-carry game back to the campsite. When this pack rack isn\'t needed, you just slip out the extension pipes, or just leave them in place, capping the frame-pipe ends with crutch tips to keep the extensions from working out.

============================

PLAN 2

These plans advertise that the pocket bike is small enoghh to fit in a school locker. That seems extreme, but the point is not lost on us — these things are tiny!

The plans call for a 3/4 hp engine, and say that it should go about 11 MPH, not bad for such a small package. At two feet in length, that speed is sure to feel like a lot faster. When you get to where you\'re going on this little racy bike, parking is no problem at all. A short piece of chain will lock up your wheels to just about anything.

Small machines are a great way to get your kids interested in tools and machinery. Give them a small engine repair book and put them in charge of repairs; soon they will learn the ins and outs of small motors.

But we\'re getting ahead of ourselves. First create that scooter with these easy to build free plans!

========================

PLAN 3

This scooter is a larger version of the gas powered scooter. The photo shows it skinned with sheet metal. This larger version would be better suited for distance driving on the street than the other on, as it is larger and more powerful.

This scooter can take a much larger motor than the plans suggest. The plans suggest that for flat ground putting, a 1.5 hp motor is adequate. We\'d suggest something much larger if you\'re interested in speed, or if you live in an area that has any amount of hills. You\'d feel pretty funny if your scooter slowed to a snail\'s pace when climbing hills.

The frame is completely angle iron, so it\'s very easy to build. The scooter plans also call for spring shocks to cushion the ride.

All in all, this scooter would be a great project for adults to cruise to neighbor\'s houses and down to the corner store.

pLAN 4

All children muse to themselves (or anyone that will listen) that it would be *so cool* if bikes had motors on them. Now they can!

These motorized bike plans call for a 1 hp air-cooled engine for the powerplant. They say that the bike will top out at 35 MPH.

Though it may now be possible, we can\'t vouch for this acutally being a good idea. Actually, it seems crazy, considering all the custom work you\'ll need to do to the bicycle. You\'d probably be better off building a scooter from scratch.

============================

PLAN 5

These are plans for a vintage style mini bikes with a torque convertor. There are two plans - the first uses a junked bicycle for parts, and the second is the super old-school traditional mini bike style.
Take a small kart engine, add a slick variable-ratio belt transmission and you\'ll have a real performance \'bear\' for half the cost of a commercial motor scooter.

On flat ground this scrappy little mini bike can hit around 30 mph. And when you come to a hill, the torque convertor will automatically downshift to a lower drive ratio to give you rugged hill-climbing power.

The best part is the machine\'s lightweight, low-cost design. The basic frame comes from a discarded 26-in. boy\'s bicycle, which you can usually pick up for a few dollars at a bike shop or junk yard. Most of the parts are stock bike or kart items, easy to come by and easy to assemble. Even if you start with a new engine, the entire scooter can be built on the cheap.

A simple mini bike is a great way to get you and your kids working together. You\'ll both learn a vast amount about small engines. It\'s a great way to encourage mechanical ability in your children. And if you give them a budget for custom work, watch thier imaginations fly dreaming up cool accessories and doodads.

PLAN 7

These are plans for a vintage style mini motorcycle.

This little motorcycle has been designed to operate on wartime rations! Its construction is simple and light, but it is surprisingly practical and will carry a 250-lb. passenger without complaining. A 5/8-h.p. engine whips it along at a 25-m.p.h. clip and as for gas consumption—one gallon for every 120 miles, and we doubt if there\'s another motorcycle that can do better than that.

The Mite Cycle shown here was built by the author at a total cost of $50. It weighs 85 lbs. and is powered by a Briggs and Stratton engine. All unnecessary frills were forgotten in its construction, and the only tools used were a small lathe, a hack saw and a welding torch. The frame, being the foundation of the project, should be built first.

It is made of salvaged aircraft streamline tubing. 2-1/2\"x.035 wall, procurable from any airport where small planes are repaired. These dimensions need not be adhered to exactly as a slightly larger or smaller tubing, or even a plain round tubing of 1-1/8\"x.035 wall, is satisfactory. After procuring the tubing make a full-size drawing of the frame on the shop floor and cut the pieces to the angles and lengths given, fitting them to the drawing as you go. After this is completed, build the two lower frame pieces.

The base tube (11-1/2\") is spotted to the forward tube going up to the fork neck and also to the rear tube going to the rear wheel hangers. Three spreaders are required and these are cut 4\" long from 1\" o.d. .035 wall tubing; two of these are located bet-ween the lower frame sides and spotted into position as noted. The forward tubes are cut on the insides and bent together to form the V as shown in the bottom view, then welded. The upper rear tubes then are laid together and the third spreader is located 9-3/4\" c.c. to the rear of the taper terminating pont and welded into position.

PLAN 8

These are two different plans for gas powered scooters you can build.
Build this gas powered scooter in your garage, and then take it for a spin! Check your local laws, based on equipment you may be able to drive your scooter on the street legally.

This scooter is a simple, sit down style. It\'s a lot of fun for keeping up with go karts, tooling around the neightborhood, and exploring. Though not intended for off road use, one could probably go trail riding because of the sturdy design.

Using a small 2.5 hp engine, this project could drive around for hours on one tank of gas.
Scooters are a great way to get your kids interested in motors and machinery. Just put them in charge of repairs, and they\'ll soon learn the ins and outs of small motors. Then give them a budget for custom work and watch them dream up cool accessories for the scooter.
