This manual contains important safety, performance and maintenance 

information. Read the manual and all warnings before taking your first 

ride on your new 3G Bikes and make sure to keep the manual handy for 

future reference. 

Unsafe or improper use of any 3G Bikes by failing to read and comply 

with all safety, performance, maintenance requirements and warnings 

could result in serious injury or death. Assembly of your 3G Bikes by any 

party other than an authorized 3G Bikes dealer voids our manufactur-

ers warranty. It is strongly recommended to have all post-sale assembly 

and service work on your bicycle performed by a properly trained and 

equipped dealer. 

When inspecting your bicycle, be certain to tighten all nuts and bolts 

properly. Under-tightening can result in loosening, parts loss and compo-

nent damage. Over-tightened nuts and bolts can break. Certain parts have 

metric hardware -- always use the correct tools. If you have any questions 

or do not understand something, take responsibility for your safety and 

consult with your dealer or the bicycle’s manufacturer.

This manual details general assembly and is not an in depth bicycle parts 

or function guide. 

Your bicycle’s serial number is stamped on the front of the head tube on 

top of the fork. Please record the serial number on your manual and make 

sure to register your bicycle online at: 3gbikes.com/bikeregistration/ 

Bicycles not registered on our database are not covered by our warranty. 

More on our warranty and serial in pages 13 &14. 

*We also recommend saving purchase invoices and receipts to better 

track your transactions.

At 3G Bikes we have over 20 different product models ranging from beach cruis-

ers to specialty bicycles like tandems and tricycles. It is important to correctly 

identify which model you have in order to correctly assemble and maintain your 

bike. Some of the most obvious differences will be the frame material, crank set, 

wheel and stem style. Below is a quick model chart.

Assembly Overview

 


background image

This diagram shows many of the major features on several of our cruiser style 

bicycles. Model pictured is a men's bicycle frame in single speed, ladies' models 

feature step-through frames which are distinguishable by a low top tube. Multiple 

speed models will vary slightly to accomodate grip shifters, brakes and some-

times a derailleur.

In order to benefit of the comfort focused design of 3G Bikes you must 

make sure that the bicycle you purchased provides the correct fit for you. 

Firstly you should be able to stand over the bicycle frame with both feet 

flat on the ground (see figure A).

Some of our bicycle models feature step-through frames which have a 

very low top tube. 

Although not all of our bicycle models are available in different frame 

sizes, we do have a range of wheel sizes from 29", 26" and 24" for adults 

in order to meet different height requirements. Our city bikes come with 

29" wheels and are available in a small and large frame size in all men's 

models. 

Bicycle Sizing

Figure A

 


background image

The correct riding position for our bicycles will place your arms extended 

in front of your body and your legs comfortably stretched out when the 

pedal is at its furthest position (see figure B). If your feet can't reach the 

pedals when they are in the furthest position we suggest lowering the seat 

post a notch. 

When setting the forward position of the handlebars, set them so that 

you can hold the handle-grips when your elbows are only slightly bent. 

You should have a strong grip and be able to easily turn the wheel in a 90º 

angle side to side. 

Seat and Handlebar

Figure B

NOTE - Seat posts have a minumum insertion mark that must 

be acknowledged, failure to do so can lead to the post bending 

or breaking. 

WARNING - Do not place the seat tube all the way in so that 

the saddle touches the frame, doing so can result in the saddle 

being pushed off the seat tube and falling off.

 


background image

There are two type of seat post clamps we use in our bicycle models. 

Some are secured by allen bolts (see figure C) while others feature a quick 

release lever (see figure D). 

Below you can see how to secure a quick release seat post clamp and 

adjust your bicycle seat. 

     1. First untighten the seat post clamp by flipping it outward and rotat-

ing it counterclockwise. Adjust the height of your seat. Noting the mini-

mum insertion mark on your seat post. 

     2. Once the seat is at desired height, rotate the seat post clamp lever 

clockwise to tighten.

     3. To secure the seat post flip the lever inwards making sure it is 

aligned to the clamp.

tools in order to correctly adjust any part.

All 3G models will feature one of two available styles of headsets and stem 

attachments, they will either be a ball bearing headset with a 1" HL quill 

stem for a threaded fork (see figure E) or a sealed headset with a thread-

less 120mm Promax stem (see figure F). 

Make sure that all components are installed in order presented. Some 

bicycle models require more or less spacers. If you have trouble adjusting 

any part of your fork and headset please contact your nearest 3G Bikes 

bicycle dealer with any questions.

The components on a 3G Bikes handlebar will vary depending on the 

speed and model of the bicycle. Single speed models do not feature brake 

levers or shifter parts. Not all multiple speed shifters look the same, but 

attachment on to handlebars will be similar. Below (see figure G) is a 

diagram showing the general assembly of handlebar components as seen 

on a three speed model. 

Break and shifter cable routing might be internal or external depending 

on the model of bicycle. Please double check bicycle frame before consid-

ering converting a single speed model into a multiple speed. 

Handlebar Components

NOTE - Specialty tools might be required for adjusting or in-

stalling shifter and break components. We always recommend 

having a licensed professional instal, adjust and repair any of 

the components on 3G Bicycles.

Figure H

Before you put your pedals on the crank arms, be sure to take note which 

pedal is which. Each pedal is indicated by a letter stamped into the end of 

the pedal axle (see figure H). 

When you have the correct pedal for the side you're on, thread the pedal 

on using just your hands at first. It should thread in fairly easily, oth-

er-wise you may be cross threading it which will strip the threads off the 

axle, ruining it. Using a wrench, tighten the pedal on fully. 

Installing Pedals

Left pedal tightens counter clockwise. 

Right pedal tightens clockwise.

Although the bottom bracket comes pre-installed on all our bicycles it is 

good to know how the general assembly of these components is in case 

of encountering problems (see figure I). Below is a diagram showcasing a 

one piece crank set, the parts involved will be slightly different on a three 

piece set.

Installing Bottom Bracket

1. Feed left crank arm into hole in center of chainring.

2. Follow this with the plastic spacer and then the threaded race. 

3. Grease the race and bearings, and feed the bearing onto the crank with 

balls facing in

4. Grease cups. Insert left crank arm through right side of bike. 

5. Grease next set of bearings and feed them to the left arm facing inward.

6. Feed the second threaded race (flat side facing out).

7. Finish with the washer and a lock nut. Make sure whole assembly is 

tight but able to spin freely.

Bottom Bracket

NOTE - The cups are the first parts to be installed into the 

frame. The threaded races thread onto the threads indicated 

on the crank itself. All pieces fit on via left crank arm (thinner 

arm)

 


background image

Some of our higher end bicycle models come with a three piece crank 

with a sealed bottom bracket (see figure J). It is called a three piece be-

cause it can be taken apart into three main components. 

Bolt

Figure J

Please note that the threaded parts might require parts to be fed in differ-

ent directions. Forcing parts onto the threads can result in damaging the 

parts.

Installing Three Piece Crank

1. Left side of the BB thread should be removable. Insert BB through right 

side and attach. Then insert loose thread through left and tighten.

2. Attach crank arms to BB and bolt in place.

NOTE - 3G Bikes always recommends having our products 

assembled, tuned and repaired by our authorized dealers. Im-

proper assembly and damage will result in a voided warranty.
