Here you will learn about the rediscovery of the recumbent bicycle after the UCI banned them in 1934 because they were too fast for the conventional upright bicycles they were racing against.
When the 1934 UCI decision turned a very conformist, top-down driven world into believing that a recumbent was not a real bicycle, recumbents disappeared from the mass consciousness for 35 years. Or in other words almost two full generations thought they knew what the bicycle under their Christmas tree was supposed to look like.
Build-a-Bike is a popular team-building event at The Leader's Institute where groups of 25 to hundreds work together to build bicycles, learning effective collaboration skills. The event concludes by donating the built bikes to a philanthropic cause in a heartwarming way.

This document provides instructions for building a motorized mountain vehicle called the "Mountain Goat" for off-road exploration. It can be built for around $300 using kart parts and a 7 horsepower engine. The frame is made of steel tubing and bent into shape. It has oversized tires, a front steering assembly, and a rear split-axle drive train connected to the engine by a jackshaft. The document includes diagrams of the frame and components, a parts list, and details on assembly to construct a rugged and customizable off-road vehicle.
The rice transporter robot hopper was optimized through finite element analysis to maximize carrying capacity within the design constraints. Initially, the uniformly thick hopper displaced 0.686mm under load, exceeding the 0.5mm limit. Multiple wall thicknesses between 2.28-2.49mm reduced displacement to 0.4997mm. Confirming calculations matched applied loads and stresses, validating the analysis. Further optimizations could increase volume by designing in sections or modifying brackets and motor placement.
This document provides instructions to build a mini bike using steel tubing and plate. It includes 15 steps to construct the frame, attach the front and rear wheels, and install the engine. Diagrams are provided to illustrate how to bend the tubing and weld various components like the front fork assembly and rear axle supports. A parts list is also included specifying the materials needed to complete the mini bike, along with sources to purchase parts.
This document provides instructions for building a simple and inexpensive scooter. Some key points:
- The scooter can be built for around $75 and uses readily available parts like a small 2-cycle engine, chain drive, pneumatic tires, and basic frame constructed from welded steel angles.
- Assembly involves welding together the frame, installing wheels and bearings, adding an engine and belt drive system, and fabricating basic controls like brakes and handlebars.
- The finished scooter can reach speeds of 20 mph and is described as easy to operate, requiring only a twist of the throttle to go with no clutch or gear shifting. It provides an affordable alternative to transport for short trips around town.
This document provides instructions for building a folding machine for sheet metal work. It describes the main components of the machine, which include a base frame assembly, two clamp assemblies, a clamping beam, and a folding beam. Detailed drawings and dimensions are provided for each component. The instructions then describe the step-by-step process for constructing each part and assembling them to complete the folding machine. Optional designs are also discussed that could adapt the machine for different sheet metal folding jobs.
This document provides full instructions for building a versatile folding machine for sheet metal work. The machine allows for readily producing sheet metal items like ducting, boxes, trays and agricultural equipment. It can be constructed from readily available steel sections by most small metal workshops using basic welding and fabrication techniques. The instructions include detailed drawings, a parts list, and step-by-step directions for assembling the base frame, folding beam, clamping assembly and other components. The clear guidance makes this a practical manual for small workshops wanting to increase their sheet metal fabrication capabilities.
The document describes the design and prototyping of a heavy lift octocopter. An octocopter uses 8 propellers arranged in 4 pairs of coaxial propellers to maximize lift. The design was optimized for an ASME student design competition rewarding payloads lifted. A coaxial design doubles lift compared to single propellers. The frame and protective shroud were manually constructed and components were chosen according to the custom design, with no preassembled kits used. The goal was to design for maximum lift within size requirements to earn the most points by lifting the heaviest payload.

entire weight. Best news about this pint- size
powercycle is its cost—about $100 for materials,
and $10 to $15 for welding if you don't do this
part of the assembly yourself. Commercial
powercycles regularly sell for over $200 to $400,
and we don't know of any domestic commercial
model that folds up the way this fellow does.
The model shown here is powered by a 2-1/2 hp
Briggs and Stratton engine and, to keep down
cost and space displacement, uses an automatic
clutch pulley (acting like a fluid drive) and no
gear shift. The speed you will get out of this
combination of course won't be sensational, nor
is any unit designed with such a low horse-power
engine intended for winning hill climbs.
But it should get you there and back with ease.
For compactness, a retrievable pull starter is
recommended, as opposed to either the rope
type (that's hard work, son) or the kick type
(which would stick out too far for driving
comfort).
Make the frame (Fig. 3) first. Thin-walled
electrical conduit (T.W.C.) is used for all frame
parts. Start by laying out the frame members
full-size on heavy paper or cardboard from the
dimensions given in Fig. 2, or use the craft
prints which show these frame pieces full size.
Cut the straight piece (A in Fig. 2) and fit the
128 SCIENCE AND MECHANICS
5. kingbolt bushings in place. These are turned from 1/2 to
3/8-in. malleable-iron pipe bushing reducers and should be
in place before the frame parts are welded together.
If you do not have a metal-turning lathe and must have
the lathe work done outside, the rear axle (Fig. 4) should
also be made at this time. Then cut piece B (Fig. 2) to
length and cut and form one end to fit snugly around
piece A at 115°. Make a wooden jig (Fig. 5) to support the
pieces when fitting and later welding. Slide a 4-in. length
of 1/2-in. conduit in the other end of piece B and flatten
the end by gripping in a machinist's vise and drawing up
tightly rather than hammering. If your vise is a small one
it may be necessary to heat the end of the conduit before
flattening.
Next, drill the 13/32-in. hole in piece B, and saw the trian-gular
seat-post brace from 3/16 x 1-in. band iron. Then weld
pieces A and B together while they are clamped with the
wooden jig, and also weld the triangular piece to the end
of piece B. Thin-walled conduit is plated with a rust proof
material which must be removed before welding. Use a
file or abrasive wheel to remove at areas where welding is
to be done. A purchased or rented electrician's conduit-bending
tool can be used to make the bends. By leaving
the conduit extra long you will have sufficient leverage to
easily bend it. Bend the conduit to the approximate radius
and angle then test for correct bending angle by placing
the conduit directly over the full-size drawing.
Next, bend, flatten and drill pieces C, D, E, F (Fig. 2). Note
that these pieces are pairs so make one each for right and left
side of frame. Cut and thread a 3/8-in. steel rod for the frame
tie-rod (Fig. 4) and use a 8-3/4-in. length of 3/8-in. pipe for the
tie-rod spacer. Now assemble all of the frame pieces with
bolts. The seat-post clamp must be in position. The rear axle
will serve as a spacer during this assembly. Make the as-sembly
jig (Fig. 6) and clamp to the frame to hold the pieces
in proper alignment. You may find that further fitting will
be necessary to get a snug fit where pieces F and A join.
130 SCIENCE AND MECHANICS
6. Use a C-clamp to hold this joint together when
welding. Cut, bend and fit brace G (Fig. 2) to
the assembled frame, and then weld in position.
Also weld the conduit where pieces E and F
join, but do not weld to, the tie-rod or spacer.
If you do not have a welding outfit and must
have the welding done at your local job shop,
make up the fork pieces (Figs. 2 and 7) before
having the frame welded so that all parts can
be welded at once. Cut two 19-1/2in. lengths of
3/4-in. TWC ( H in Fig. 2) and two 8-in. lengths
of 1/2-in. TWC. Slide the 1/2-in. TWC into the
3/4-in. TWC and flatten to 1/2 in for a distance of
6 in. from one end. Lay out, drill and tap all the
holes in pieces H. If possible, clamp the two
pieces together when drilling so that the holes
line up perfectly. Make the front axle and
quill axle (Fig. 4) at this time so that they can
be used to clamp the fork parts together during
welding. Cut the two angle-iron' pieces (J in
Fig. 7). Clamp both angle-iron pieces together
when drilling so that the 15/16-in. holes will be
equally spaced in both pieces. Unless you have
a metal-turning lathe, have this drilling done at
your local machine shop. Also have two 2-in.
lengths of 1/2-in. standard pipe bored or drilled
out to take 1/2-in. TWC for handlebar clamps (K
in Fig. 3). Then cut the clamps lengthwise with a
hacksaw. File a semi-circle in the top ends of
pieces H to take the handlebar clamps (Fig. 2).
Make pieces L in Fig. 3 from 1 x 1-in. angle iron.
Cut, bend and drill pieces M in Fig. 3 and bolt to
pieces J before welding . Then assemble pieces H
and J using C-clamps and fit it temporarily to the
frame with the kingbolt to assure a close
and smooth turning action. Be sure that pieces
H and J are at right angles to each other before
welding. Clamp and weld pieces K to each H
piece and upper J piece with saw cuts to the
center of the fork facing each other as shown
in Fig. 3. Then position and weld pieces L. to
pieces K only. They are not welded to upper J
piece. Drill 9/32-in. holes through pieces L and tap
upper K piece 1/4-28 for 1/4-28 handle-bar clamp
bolts.
Now cut and bend the handle bars (N in Fig.
2) and insert into clamps K. Tighten the 1/4-
in. bolts until the handle bars can just forcibly
be swung down or up. Do not drill the holes
through pieces K and N for the locking pins O
until the powercycle is completed because the
exact driving position will vary somewhat de-pending
upon the height of the rider.
Make and install the engine support bars (P
in Fig. 7) after the frame is welded. The U-bolts
allow the engine to be moved forward or
backward for belt tension adjustment. Do not
drill the holes for mounting the engine until
the drive pulley on the rear wheel is installed.
Cut and bend the kick stand pieces Q and R as
in Fig. 7. Tighten the 5/16-in. bolt and use a nut
to lock and adjust the bolt tension so that piece
R will stay in the up or down position by fric-tion.
Use a lock washer between pieces Q and
R if necessary. Then bolt the kick stand unit
to the frame with the rear right-hand, engine-support-
bar U-bolt. Make the two frame fender
brackets (Fig. 7) and bolt to the frame for the
rear fender, which will be installed later.
Part 2, appearing in the next issue, will show
you how to assemble the engine, drive belts,
brakes, throttle controls and accessories.

WHEN the powercycle frame is com-pletely
assembled (part 1, S&M Feb-ruary,
1955), your next step is to in-stall
the rear-wheel assembly. Inasmuch as
this is a trial assembly for cutting and fitting
the parts to proper size, leave the rear fender
installation until later after the frame is
painted. The rear wheel mentioned in the
materials list, part 1, comes complete with
flange and threaded lugs for mounting the
driven pulley and rear brake drum. Two
driven pulleys are available. A 9-in. dia. one which will give
the powercycle maximum pulling power for hilly streets and
an 8-in. dia. pulley which "will give the powercycle the maxi-mum
speed. In either case drill through the heads of the three
pulley-mounting cap screws and wire as in Fig. 9 to prevent
their loosening and falling out. Cut the two rear-axle spacers
(S in Fig. 9-A) from 3/4-in. O.D. x 18-gage steel tubing slightly
oversize and file ends until tubing spacers can just be turned
by hand when assembled with the rear wheel in the frame

8. working on the machine. Then place the engine
on the engine support bars. At this point you
will have to decide whether you are going to use
the automatic clutch and drive pulley or the foot-controlled
belt-tightener type of drive clutch
(Fig. 8). In either case place the pulley on the
engine shaft as close to the engine as possible
and line up the drive pulley on the engine shaft
with the driven pulley on the rear wheel with a
yardstick or straightedge (Fig. 11). Then mark
the location of the four engine mounting bolt
holes on the engine support bars. Remove the
engine and support bars and drill the 3/8-in. holes
in the bars. Reassemble the support bar to the
frame but do not tighten the U-bolt nuts because
the position of the bars are determined by the
length and tension of the drive V-belt. The en-gine,
however, can be mounted on the bars and
permanently bolted to the bars with 5/16-in. cap
screws drilled for cotter pins.

the cap screws just enough to allow the foot
pedals to be moved up and down without any
play. Grease the bearing surfaces.
To support the movable idle-pulley arm, lay
out, saw and bend the idle-pulley bracket (Fig.
9-B) and fasten to the left side of the front en-gine
support bar with the U-bolt (Fig. 9). If
the rear-wheel hand brake is to be included (re-quired
by some states), you will save yourself
some time by making the hand-brake bracket
(Fig. 9-B) and installing it at the same time you
bolt the idle-pulley bracket in place.
When working on front and rear wheel assemblies,
place powercycle on a box and secure to top with
a C-clamp.
To make the movable idle-pulley arm, heat a
3/8-in. dia. steel rod to make good sharp bends
(Fig. 9-B). It may be necessary to file the bear-ing
surfaces of the rod slightly as indicated, to
seat the washers at right angles to the rod. Drill
the 3/32-in. hole for the control wire. Use two
3/8-in. I.D. ball bearings (see materials list) for
the idle pulley and assemble with washers and
cotter pins.
Make the two cable brackets (Fig. 9-B) and
bolt in position. The cable control wire is a
length of automobile choke wire cut to length so
that it will reach from the left foot pedal to the
movable arm (Fig. 9). Allow enough slack so
that the control wire will not interfere with

10. steering the front wheel. Be sure to bolt a belt-guide
bracket to engine (Fig. 8) if the idle-pulley
type of drive is used. This bracket will
prevent the belt from being thrown off the en-gine
pulley. Adjust the belt tension by sliding the
engine support bars on the frame; then tighten
the U-bolts.
If the rear-wheel hand brake is to be included,
make the parts de-tailed
in Fig. 9-B
and temporarily
install them (Fig.
9) at this time. Be
sure to counter-sink
the brake-band

While the paint is drying, make the front and
rear fender brackets (Fig. 15). Both the front
and rear fenders are cut from one large-size,
chrome-plated rear bicycle fender. After cutting,
the fenders can be easily flattened somewhat to
make them wide enough for the powercycle
