SAFETY2
2.1 General Warning
Thismanualcontainsmanywarningsandcautions,whichifignored,mayincreasetheriskofinjury
toyouasarider,maycausedamagetotheproductormayinvalidatethewarranty.Werecommend
thatyoureadandunderstandthismanualinitsentirety,priortoyourfirstride.
Riding any bicycle involves the risk of product damage, serious injury or even death. Such risks are
increased in busy, urban environments with moving traffic. By choosing to ride a Gocycle, you
assume the responsibility for these risks, and it is important that you know how to ride responsibly
and to exercise proper maintenance to minimise such risks and potential damage. Do not try to ride
beyond the limits of your ability or the limits of the Gocycle.
Westronglyrecommendthatyoulearnmoreabouttheinherentrisksassociatedwithridingbicycles
andsuggestthatyou:
Askyourlocalbikeretailerforinformationorinstructiononsafecycling.
Ridewithinyourmeansandability.
Attendatrainingsessionorsafecyclingworkshoprunbymanylocalbikeclubs,police

Search“bicyclesafety”onlineforreferenceinformation.
Skillsofriderscanvary;forexample,ittakesahighlyskilledridertotravelathighspeedsand/or

environment.Whereapplicable,theproductmeetstheminimumrequirementsoutlinedinEN
14764:2005andEN15194.Abusiveridingstylesorinappropriateusewillinvalidateanywarranty
protectionofferedinthisagreement.
WARNING! Understand your Gocycle and its intended use. Using your Gocycle in the wrong manner
or for the wrong purpose can be dangerous and may impact the service life of the product.
TheGocycleisapower‐assistedbicycleintendedforsensibleusebyphysicallycompetentriders.If

2.3 Modifications and Refinishing
WARNING! Do not modify or refinish your Gocycle or Gocycle components in any way. Such
modifications or refinishing will void any applicable warranty.

Modificationscancausedamagewhichcanincreasetheriskoffailureandaccidentwhichmayresult
inseriousinjuryordeath.Refinishingcanhidestructuraldamage,suchasfatiguecracksorstructural
problemswhichmayalsoresultinanaccident.
2.4 Maximum Design Limit
WARNING! This product has been designed with a maximum weight limit of 100kg (220lbs) for the
rider, clothing and all luggage. Do not exceed this weight limit at any time. Exceeding this limit will
void all warranties, may reduce the fatigue life of the product and may result in the product being
unsafe for operation.
2.5 Riding in Low Light Conditions
Inlowlightconditionsatnight,dawn,duskorduringadverseweatherconditionssuchasfog,the
visibilityofcyclistsisdramaticallyreduced.
WARNING! Never ride a bicycle in low light conditions without appropriate front and rear lights fitted
and “on” (illuminated) that meet or exceed the national standards of the country in which it is being
ridden.
Werecommendthatyouconsulttherelevantnationalsafetyorganizationorareputablecycledealer
onwhattheminimumrecommendedlightingrequirementsareinyourparticularcountryorregion.
Forreferencewhenselectinglights,yourGocyclehasa34.9mmdiameterseatpostandupper
handlebarstem.Werecommendthatyouchoosealightwithavariablelengthstrapmounting
system.
Thefollowingareadditionalrecommendations:
Wearbright,reflectiveclothingsuchasreflectivevests,legandarmbands
EnsurethatyourGocycleisequippedwithcorrectlypositionedreflectors(see4.2Assembling
theFrontandRearReflectors)
Ensurethatyourclothingdoesnotobstructtherearlights/reflectors
2.6 Riding in Wet, Cold or Icy Conditions
Underwet,coldoricyconditions,thestoppingpowerofyourbrakesandtyres(aswellasthebrakes
ofothervehiclessharingtheroad)isdramaticallyreduced.Thismakesithardertocontrolspeedand
easiertolosecontrol.Italsomakesskiddingduringturningmorelikely.Ridemoreslowlyand
cautiouslywheninwetweather.Ifitiscold,nearorbelowthetemperaturewhenwaterfreezes,be
carefuloficeontheroadswhichcouldbedangerous.
WARNING! Wet weather impairs traction, braking and visibility, both for the cyclist and for other
vehicles sharing the road. The risk of an accident is dramatically increased in wet conditions.
Tomakesurethatyoucanslowdownandstopsafelyinwetconditions,ridemoreslowlyandapply
yourbrakesmoregraduallythanyouwouldundernormal,dryconditions.

2.7 Limited Life Span
WARNING! Bicycles have a limited life span for safe operation and are not indestructible.
Aswithallmechanicalcomponents,bicyclecomponentsaresubjecttowearandhighstresses.
Differentmaterialsandcomponentsmayreacttowear,stressorfatigueindifferentways.Exceeding
theusefullifeofyourGocyclemaybehazardous.
TheexpectedlifespanofaGocycleorGocyclecomponentwillvarywiththematerialand

andamountofriding.Anyunusualorabusiveridingstyle,suchasoff‐roadcycling,competitive
riding,stuntcycling,jumpingorridingatexcessivespeedandbrakinghard,canacceleratewearand

withoutwarningandriskofinjuryisincreased.
Anyformofcrack,scratchorchangeofcolouringinhighlystressedareasindicatesthatthelifeofthe

2.8 First Ride
WARNING! First familiarise yourself with the modes of operation, controls and performance of your
Gocycle before venturing onto busy streets.
WestronglyrecommendthatyoufamiliariseyourselfwithyournewGocyclebyfirstridingitina
controlledenvironment,awayfrompotentialhazardssuchasmovingtrafficandobstacles.Itis
importanttobecomefamiliarwiththemodesofoperation,controls,brakesandthedifferent
performancecharacteristicsinherentintheelectricmotor.
WARNING! Your braking efficiency will increase during the first few rides as your brake disks and
pads “bed in”. To accelerate the increase in braking performance, perform a number of controlled
stops under hard braking.
2.9 Caution: Do Not Over-Rotate the Handlebars
It is possible to cause damage by over-rotating the handlebars. Over-rotating the handlebars beyond 90 degrees
from a straight-ahead position can cause the internal cabling to be stressed under tension and in severe cases
can cause internal breakages resulting in loss of function.

CAUTION: DO NOT ROTATE THE HANDLEBARS BEYOND 90 DEGREES FROM STRAIGHT
Never over-rotate the handlebars. Damage caused by ignoring the warning will not be covered under warranty.
2.10 Pre-Ride Checklist
WARNING! Before every ride, you should complete the following checklist. If you answer “no” to any
of the questions, you should not ride your Gocycle and seek advice.
If you have any reason to believe that your Gocycle is not functioning properly, or that you are aware
that your Gocycle has been damaged in any way, do not ride it.
