Frame Parts 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.
Bicycle Sizing 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).
Seat and Handlebar 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.
Adjusting Seat 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). Figure D Figure C Below you can see how to secure a quick release seat post clamp and adjust your bicycle seat.
Adjusting Handlebar 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).
Handlebar Components 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.
Installing Pedals 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.
Bottom Bracket 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.
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.
In order to validate your warranty it is necessary to have your bicycle assembled by an 3G Bikes dealer. Claims should be processed through an authorized dealer. This warranty is limited to replacing the defective part without charge and the company shall in no event be responsible for consequential or special damag- es.
