Introduction&

"
I’m"Adam"Crouchley,"founder"of"www.d9trikes.com."I"started"drift"
triking"in"2009"and"since"we"set"up"the"website,"the"worldwide"drift"
trike"community"has"gone"from"strength"to"strength."
"
Building"a"drift"trike"is"a"lot"of"fun"and"very"rewarding."You"can"be"as"
creative"as"you"like"when"you"are"building"your"trike"and"you"may"
just"learn"a"few"things"about"physics"and"engineering."This"ebook"
won’t"tell"you"exactly"what"you"need"to"do,"because"everyone"has"
access"to"different"tools"and"parts."This"e9book"will"give"you"the"tips"
and"show"you"the"tricks"you"need"to"successfully"use"the"parts"you"
can"get"your"hands"on.""
"
At"the"completion"of"this"book"you"will"be"able"to"build"an"entry"level"
drift"trike"and"start"enjoying"the"buzz"of"downhill"drift"triking!"
"
The"methods"and"styles"used"in"this"book"are"methods"that"have"
worked"and"are"proven."There"are"a"lot"of"methods"that"are"better"
but"take"a"lot"more"time"or"money"to"get"a"similar"result."
"
I"would"like"to"thank"all"the"guys"around"the"world"that"regularly"
solve"peoples"problems"on"our"website."With"out"you"guys,"drift"
triking"would"not"be"what"it"is"today."
"
Right"from"the"start,"we"would"like"to"point"out"that"drift"triking"can"
be"a"dangerous"sport,"you"will"be"riding"on"public"roads"and"often"
with"other"traffic."You"must"always"follow"the"road"rules,"local"laws"in"
your"state/country"and"you"always"wear"safety"gear.""We"speak"on"
this"topic"from"experience."
"
Safety"first."Ride"safe."

"
PLANNING%
Like"any"project,"you"need"to"plan"your"build"from"the"start"so"you"
can"get"it"finished"and"get"out"there"sliding!"
"
Draw"your"trike"out"in"fine"detail."Work"out"what"parts"you"have"and"
what"you’re"going"to"need."Remember"the"number"one"rule"when"
building"a"drift"trike;"
"

“Light, Strong, Cheap ... Pick two”

"
"
BASIC%MEASUREMENTS%
There"has"been"a"lot"of"talk"around"ideal"wheelbase"for"a"drift"trike"
and"to"date"this"is"the"best"we’ve"seen."Axle"to"axle"length"(front"to"
rear)"is"best"around"1000mm"91100mm"and"width"outside"to"outside"
of"wheels"around"900mm"is"good."
"
When"you"mount"your"seat,"your"seat"should"be"set"so"that"the"rear"
axle"sits"around"1009200mm"behind"your"lower"back."

Frame&

A"frame"can"be"built"in"any"design,"but"the"front"end"needs"to"be"
made"from"a"bicycle"of"some"description."This"can"be"a"BMX,"
mountain"bike"or"even"a"pitbike"front"end."The"most"common"choice"
is"BMX"because"they"are"cheap"to"get"hold"of"and"the"small"20”"
wheel"doesn’t"rub"on"your"leg"like"the"larger"mountain"bike"wheel"
does."

"
When"you"are"choosing"a"bicycle"
to"tear"apart,"first"check"what"
kind"of"steel"the"bike"is"made"
from."If"it"is"alloy,"you"will"need"
to"TIG"weld"the"frame.""
"
Some"people"use"more"of"the"
bike"frame"when"building"their"
Pic 4 – Most frames have their own style%
drift"trike,"but"often"these"frames"
will"break"just"in"front"of"the"seat."Normally"a"bicycle"doesn’t"bear"so"
much"load"at"this"point.

"
Most"commonly"used"for"the"
frame"is"2”"(51mm)"exhaust"
tubing"with"a"1.6"or"2mm"wall."
Sometimes"RHS"is"used"for"the"
frame"too."

on"the"below"trike"is"where"a"frame"is"most"likely"to"snap,"and"they"
often"do"if"not"reinforced.""

Use"what"you"can"to"support"
parts"when"assembling"your"
frame."Tack"it"together"and"then"
measure"it"up"to"make"sure"it"is"
square."Turn"the"front"wheel"to"
90"degrees"to"make"sure"the"
frame"doesn’t"hit"the"ground"at"
full"lock."
Pic 7 – A frame built from scratch

"
Pic"8"shows"about"the"right"amount"of"angle"for"the"headpiece/forks,"
often"referred"to"as"‘rake’."This"is"hard"to"measure"the"angle"of,"
especially"while"building"a"trike"with"no"wheels"on"it."
Headpiece"should"be"between"15"and"25"degrees"from"vertical."
Closer"to"15"degrees"for"a"low"speed"trike,"more"angle"if"you"are"
building"a"trike"for"high"speed"use.""

Wheels&
"

There"are%3"common"types"of"wheels"that"are"used;"
9""Replacement"wheels"like"Huffy"Green"Machine"wheels"(fig%9)%"
9""Go9kart"wheels"(fig%10)"
9""Trolley"wheels"(fig%11)"
"
All"3"options"are"great"for"different"applications"and"resources"that"
you"have"access"to."Some"are"more"suited"to"high"speed"runs"and""
"
Replacement%plastic%wheels"are"an"easy"fit"for"your"new"drift"
trike."These"are"sold"as"replacement"wheels"for"the"likes"of"the"Huffy"
Green"Machine"or"the"Big"Drift"trike"from"Mad"Dog"Cycles."These"use"
a"12mm"axle"and"are"hollow"plastic."
"
Pros"–"easily"interchangeable,"these"can"be"held"on"with"just"a"
split"pin"or"nylon"lock"nut."They"are"cheap"to"buy,"light"weight"and"in"
most"case"they"are"fairly"easy"to"source."
"
Cons"–"they"wear"out"fast"on"coarse"chip"and"because"they"are"
made"of"hollow"plastic"they"are"very"noisy."The"insides"have"been"
known"to"heat"up"and"melt"if"they"rub"the"axle"housing"(but"lubricant"
helps"with"this"problem)."

%

GoBkart%wheels%are"a"common"fitment"and"are"the"front"tires"from"
a"standard"go9kart."Standard"sizing"is"10x4.5"inch."The"tire"is"deflated"
and"a"plastic"sleeve"is"put"over"the"tire."The"tire"is"then"re9inflated"
which"holds"the"plastic"in"place.%
"
"
"
Pros"–"Sleeves"are"easily"interchangeable."The"low"friction"
bearing"rear"end"will"handle"anything"you"throw"at"it"and"it"will"
practically"be"maintenance"free."They"are"very"quiet"compared"to"
replacement"wheels."
"
Cons"–"Go9kart"wheels"are"heavier."This"does"not"so"much"
effect"operation"of"the"drift"trike"but"you"will"be"lifting"the"trike"onto"
a"trailer"or"truck"many"times"through"the"day.""
