· Nuts, bolts, quick-release and parts are fastened tight, not worn, or damaged. · Riding position is comfortable and unencumbered. · Brakes are operating effectively. · Steering is free with no excessive play. · Wheels run true and hub bearings are correctly adjusted. · Wheels are properly secured and locked to frame/fork. · Tires are in good condition and inflated to correct pressure (tire pressure in on
tire sidewall – do not exceed max tire pressure). · Pedals are securely tightened to pedal cranks. · All reflectors are in position and secure.
After you have made any adjustment to your electric bicycle, check that all nuts and bolts are securely tightened and cables are free from kinks and fixed securely to the electric bicycle frame. Every six months, your electric bicycle should be professionally checked to ensure that it is in correct and safe working order. It is the responsibility of the rider to ensure all parts are in working order prior to riding this electric bicycle.
3.2 What Never To Do When Riding NEVER ride without wearing an approved helmet, which must meet USA/European (CPSC/EN) standards. Always comply with the local laws and ordinances.
· NEVER ride on the same side of the road as oncoming traffic. · NEVER carry a passenger, this bicycle is designed for a single rider only. · NEVER hang item(s) over the handlebars, this could interfere with steering or
catch in the front wheel causing a crash. · NEVER hold on to another motor vehicle or bicycle. · NEVER ride too close to another vehicle – keep your distance and awareness.
WARNING! Wet Weather Riding: Your bike’s brakes do not work as well under wet or icy conditions as they do under dry conditions.The braking distance in wet weather will be longer than that in dry conditions. Take special precautions in wet weather to assure safe stopping. Ride slower than normal and apply your brakes well in advance of anticipated stops.
WARNING! Night Riding: Do not ride at night. If you have to be on your e-bike at night or in low-light conditions, always comply with laws and regulations (local and otherwise) for bicycle lighting. Use approved headlights (white), taillights (red) properly affixed to your e-bike in addition to all-around reflectors.

2.2 Installing the Front Fender 1. Locate the long bolt, washer, and nut which will either be in the parts bag/box or inserted in the top of the fork. 2. Slide the fender in place from the back of the fork. Insert the long bolt through the top/center fork hole from the front of the bike. At the rear of the fork hole, place the bolt through the fender mounting tab with the washer and nut. While pushing the fender tab up as far as it will go, tighten the bolt and nut to secure the fender to the top of the fork (Fig. 8) 3. Position the fender braces to the mounting holes on the fork dropouts. It’s okay to squeeze inward as these braces are designed to be pliable. Partially thread the screw through the fender brace end hole and into the dropout – repeat for the other side. When both braces are partially attached, tighten the brace screws to complete the install (Fig. 9) 4. If the fender is not straight, or rubbing the tire, that’s okay! As mentioned above, the fender braces can be bent to center the fender. Gently adjust the fender by hand until it’s straight.
NOTE: Rear Fender Adjustment: The rear fender is installed at the factory and should be good-to-go. However, it may require some small adjustment due to shipping. Follow 2.2 step 4 to straighten as necessary or a combination of loosening the brace end bolts, retightening, and centering.

The handlebar has been pre-assembled together with brake levers, shifter levers and grips. Be sure that the longer cable is fixed to the right lever (rear brake) and shorter cable to the left (front brake). (NOTE: In some areas, such as the UK, the cables are required to be arranged in the opposite way).
Your e-bike may be fitted with an adjustable stem, a standard quill stem, or a threadless stem (Refer to Fig. 12). Regardless of stem type, always check that all the bolts are tight before riding. Respect the stem type and follow the instruction below:
1. For Quill Stem: Insert the handlebar stem into the fork steer tube to the minimum height line that is marked on the side of the handlebar stem. It may be necessary to loosen the stem Expander Bolt so that the stem can slide into the fork tube, until you get your desired height of the handlebar stem. For Threadless Stem: Slide the stem over the fork steer tube.
2. Align the handlebar stem with the front wheel (See Fig. 13). Securely tighten the stem bolt(s). Note: Some models require a 6mm hex key. (Tightening torque: 18N.m or 14foot lbs.torque).
3. Positioning the Handlebar: · Loosen the stem handlebar clamp bolt (Quill) or hex bolts (Threadless). · Position the handlebar at the desired angle. Make sure the handlebar is in the
center of the stem handlebar clamp. · Tighten the handlebar clamp bolt (tightening torque: 18N.m or 14footlbs.lbs).
4. Be sure that your handlebar and stem assembly is properly tightened before riding. The handlebar and stem should not rotate in the stem up or down or in the fork from left or right. (Fig. 13)

Step 5: Installing Pedals (Refer to Fig. 14) The pedals are marked with either a “R”(Right) or “L” (Left) on the threaded end of the pedal axle. Screw the pedal marked by” R” into the right side of the crank assembly (chain side of bicycle). Turn the pedal (by hand) in the clockwise direction. Tighten securely with a 15mm open-end, 15mm pedal specific wrench, or adjustable wrench (tighten to torque: 34N.m or 26 lbs). Screw the pedal marked by “L” into the left side of the crank assembly. Turn the left pedal (by hand) in the counterclockwise direction. Tighten securely with a 15mm openend, 15mm pedal specific wrench, or adjustable wrench (tighten to torque: 34N.m or 26 lbs).

Step 6: Brake Adjustments The brakes on your bicycle should be correctly adjusted from the factory. However, as cables do seat and stretch. It is important to check the function of your brakes after your first ride. Most brakes will need some adjustment after being used a few times.

Basic Disc Brake Adjustment The following instructions are not exhaustive. We strongly suggest you take your bike to your place of purchase, professional bike shop, or certified ebike mechanic for assembly, adjustment, and maintenance.

A. Brake Lever and and Brake Pad Travel Adjustment You can adjust the amount of braking leverage by adjusting the brake lever travel and by the closeness of the brake pads to the brake disc.

Brake Lever/Cable Adjustment: To adjust

the travel of the brake lever, loosen the

Locking Collar A1 (away from lever body),

turn/unscrew the Adjusting Barrel A2

(what the cable enters) left/counter-

clockwise which tightens cable tension

and increase lever travel & leverage, this

will bring the caliper brake pads closer to the disc (Fig. 15). If the pads are rubbing

A2 A1

against the disc, reverse the process.

If you have tuned the Adjusting Barrel to its maximum and the lever travel is

Fig. 13 Brake LeFviegr. A15djustment

still excessive you will have to adjust the

space between the pads and the disc.

Tighten the Locking Collar up to the lever body.

Additional adjustments at the caliper (Fig. 16).

Caliper Adjustment: Insert a hex key into the smaller hole inside hex key hole B (Fig.16). Rotating the allen key clockwise/right pushes the outer brake pad forward by approx.0.8mm. After each turn, check the braking function, so the pads are close, but do not rub the disc.

Smaller Keyhole Inside Main Hole
Fig. 14FAidDgj.ius1sc6tmBreankte Pad

Fig. 15ADdijFsucisgtB.m1r7aeknet Pads

Once the correct amount of travel has been reached, centre the brake Caliper on the disc by adjusting screw C (Fig. 17). When the brake pads are centered on the disc the wheel should spin freely with no rubbing. Upon applying the brake(s), there may be a slight amount of noise until the pads “bed” in, this should stop after your first ride. Make sure there is no oil or grease on your hands or on the disc which can degrade brake performance.
B. Checking Brake Pad Wear, Pad Replacement
Pads that are 1mm thick (or less) need immediate replacement (Fig. 18).

FFiigg.. 1168

FFiigg..1197

To install new pads, remove the brake caliper from the fork or frame by unscrewing hex bolts D (Fig. 19). Unscrew (left/counterclockwise), the smaller hex bolt inside allen bolt B (Fig.14). Lift up and pull the inner pad downward, using the protruding tab. Slide a thin slot screwdriver under the outer pad and lift it up. Hold the screwdriver in this position and remove the pad with a pair of long- nosed pliers.
Remove the springs from the worn-out pads and fit them onto the new pads. Replace the new pads, keeping them slightly inclined into the seat of the Caliper.
Check that the spring hooks correctly onto the small piston. (When pulling downwards the pads should not come out). Refit the Caliper to the fork (or frame for rear brake). Turn adjuster screw C (Fig.17) until the pads are centered on the disc and the wheel spins freely. Again, there may be some noise from the brake until it “bed” in. You may have to adjust the cable tension and lever adjustment – follow previous Step A. Brake Lever and and Brake Pad Travel Adjustment.
We strongly advise you have your brakes periodically checked and maintained by your dealer or a professional bicycle mechanic.

Step 7: Derailleur Gears Maintenance and Adjustment The gears/derailleur(s) on your bicycle should be correctly adjusted from the factory. However, as cables do seat and stretch. It is important to check the function of your shifting after your first ride. It is not unusual for your shifting system to need some adjustment after being used a few times.
We strongly recommend you have your e-bike serviced by your dealer or professional bike shop/mechanic.
To ensure long life and efficiency for your drivetrain system, it must be kept clean and properly lubricated. Before attempting any adjustments, make sure you understand the drivetrain components functions and feel confident to attempt such maintenance.
· Left shifter controls the front derailleur and chain wheel(s); Right shifter controls the rear derailleur and rear cogset.
· The largest/larger rear sprockets on the cogset are the low [speed] gears used for hill climbing and low speed technical riding; the smallest/smaller rear cogs are for cruising and high(er) speed and downhill riding.
· For maximum efficiency, best riding experience, and long life, avoid using “crossover” gears, for example: the large front chainring with the large rear cog, OR or the small front chainring with small rear cog.
NOTE: For good shifting and riding experience, follow these 4 actions: 1) Shift only when pedaling (forward), do not shift when stopped. 2) Do not use hard, aggressive pedal pressure while changing gears. 3) Never back pedal when changing gears. 4) Never force the gear shifting levers.
Rear Derailleur Adjustment: There are two limit adjustment screws on the rear derailleur – High/”H” and Low “L”. Looking from the rear of the bike forward, the limit adjustments center the chain on the high/large and low/small rear cogs which prevents the chain from going over the large cog and into the wheel/left (the “H” or high adjustment screw) or into the frame/ right (the “L” or low adjustment screw).
First, the derailleur cable tension needs to be correct:
Position the shifter(s) so the chain is on the smallest rear cog and largest front sprocket – check for cable slack at point “B” (Refer to Fig. 20). If there is slack, loosen the cable nut or hex bolt, pull the cable with pliers and retighten the cable nut/bolt while pulling cable taut (tightening torque: 5-7N.m or 4-5 lbs)

High/Large Cog (“H”) Limit Adjustment Turn the “high limit” adjust screw marked “H” on the rear derailleur so that, again looking from the rear, the upper guide pulley is below the vertical plane of the center of the top/large cog.
Low/Small Rear Cog (“L”) Limit Adjustment Turn the “low limit” adjust screw marked “L” on the rear derailleur so that, again looking from the rear, the upper guide pulley is below the vertical plane of the center of the low/small cog.

1. Operate the shift lever to shift the chain from top gear to 2nd gear. · If the chain will not move to the 2nd gear, turn the cable adjusting barrel on the
   rear derailleur to increase the tension (counterclockwise) · If the chain moves past the 2nd gear, decrease the tension (clockwise) 2) Next, with the chain on the 2nd gear, increase the inner cable tension while turning the crank forward. Stop turning the cable adjusting barrel just before the chain make noise against the 3rd gear. This completes the adjustment.
   Make sure the drivetrain is clean. We suggest “dry” lubricants for most applications.
   Step 8: Check Before Riding Make sure the wheels are tight and secure. Tighten the front and rear hubs nuts securely. (Tighten torque: about 30N.m for front wheel, about 25 ot 30 N.m for rear wheel).
   For Quick-Release (QR) hubs/axles, make sure the QR levers are in the locked/closed position. Before riding, lift the front of the bicycle so that the front wheel is off the ground, lightly bounce it to the ground and give the top of the tire a few downward strikes. The wheel should not wobble or come off and there should be no rattling. Do the same for the rear wheel.

4.3 Selecting Pedal Power Assistance Level on Handlebar Display Panel: When the power is on, you can shift to 3 pedal power assistance levels: Low, Middle, & High. Press the “-” button or “+” button, to shift the pedal power assistance levels between the lowest and highest levels.

Setting the Pedal Power Assistance Level: When the power is turned on, the pedal power assist level defaults to the “middle/ medium” 2nd LED light.. From there, press the “+” and “-” buttons to increase or decrease pedal power assistance respectively .

Assistance Level – Riding Conditions High Assistance Level: More electric power, less human propulsion are applied to the bike. Suited for uphill, head wind, or heavy load riding.

Middle Assistance Level: Electric power and human propulsion are applied almost fifty/fifty to the bike. Suggested for riding on flat paved roads, cruising, and moderate fitness.

Low Assistance Level: Less electric and more human propulsion applied to the bike. This is the maximum electric power savings (economic) level. Suggested for fitness, lower speeds, technical riding, crowded [multi-use] paths.

Power Saving Alert: Using the 4 LED lights, the power display panel can alert users to turn off the power to save energy/riding range.

If the user forgets to turn off the power (battery) switch; after being stopped for five minutes the four LED lights will “cycle” – light-up one after another. This reminds the user to promptly turn off the power to save energy/riding range.

WARNING! Turn off the main switch on the battery as soon as you are done riding. This is very important for saving the battery charge. This will extend your riding range and reduce “top-off” charging during rides.

Procedure for Charging Charge the bike battery according to the following procedure: 1. When charging the battery by AC (house/wall plug), it is not necessary to be on. 2. Securely insert the charger output plug into the battery, then plug the main cable of the charger into a reachable AC (wall plug) outlet. 3. During charging, the LED on the charger pack will be RED showing charging is in process. When the light on the charging pack turns GREEN, charging is complete. 4. Upon full charge (GREEN light), FIRST disconnect the charger pack from the AC (wall plug); SECOND disconnect the charger output plug from the battery pack. FINALLY, close the charging socket cover on the battery – make sure it is securely closed.
7. Using and Maintaining the Electric Hub Motor. Retrospec intelligent e-bikes are programmed to start with the electric assistance (“Start-Aid”) after a rotation of the pedals (crankset). · Do not use this bike in flood waters, heavy rain. · Do not immerse, submerge the electric parts in water – damage will likely happen. · Avoid impacts to the hub motor, the aluminum alloy hub cover may break. · Regularly check the screws on both sides of the hub motor; tighten them as
necessary even if they are only a bit loose. · It is necessary to periodically check the cable connection to the motor.
8. Maintaining the Controller. Retrospec e-bikes have the Controller (the e-bike “brain”), positioned at the bottom and inside the battery pack holder/housing. The Controller is a critical component for your e-bike system. It is very important to follow the care guidelines below:
Do not immerse, submerge the electric parts in water – damage will likely happen.
NOTE: If you think water may have got into the control box, switch-off the power immediately and pedal without electric assistance. You can pedal with electric assistance as soon as the controller has dried out.
As with the battery, hub, display and other electrical parts – Never strongly shake, slam/drop, or throw the Controller – damage is likely.
As with the battery, the best operating temperatures for the controller is: 5F-104F (-15°C to +40°C).
The controller should be used in normal working temperature range from -15°C to +40°C
WARNING! NEVER open the controller box. Any attempt to open the controller box, modify or adjust the controller will void the warranty. Please ask your local dealer or authorized service specialist to repair your bike.

Trouble Description
After the main battery switched on, the motor does not generate assistance when pedaling.

Possible Causes
1)the motor cable (waterproof connection joint) is loose; 2) brake lever did not return well, which keeps the switch in “power off” position; 3) battery fuse is broken; 4) the speed sensor is too far away from the magnetic ring on the B.B. axle; 5) the connection between the sensor and the controller is loosen or not connected well.

Trouble Shooting
First of all, please check the battery if it is empty. If yes, charge the battery immediately. 1) check if the connection is securely fixed. If loose, joint them tightly. 2) make the brake lever come back to its normal position with care, without braking; 3) open the battery pack top, and check if the fuse is broken. If yes, please visit your vendor or authorized service for installing a new fuse; 4) adjusting the distance between the magnetic ring and the sensor, to make sure the distance is within 3mm; 5) fix tight the connection between the sensor and the controller.

The distance per charge becomes short (Note: performance of the bike battery is directly related to weight of the rider and any baggage/load / wind / road / constant braking).

1. charging time is not enough; 2) the environment temperature is so low that it affects the battery working. 3) frequently going uphill, or riding with head wind, or on poor road condition, 4) the tyres have low pressure (to be inflated); 5) frequently braking and starting. 6) battery has been stored without using for quite a long time.

After plugging the power outlet, no charger indicator LED is lit.

1. trouble from the power outlet; 2) poor contact between charger input plug and power outlet; 3) the temperature is too low.

2. please charge the battery according the instruction (chapter 7.3); 2) in winter or under 0°C, you’d better store the battery inside the house; 3) it will be normal if the riding conditions are improved as regular; 4) pump the tyres and ensure tyres are fully inflated to 45psi for your bike; 5) it becomes normal when the riding situation will be better. No worry about such a trouble; 6) make regular charging according to this instruction manual (refer to Chapter 6.3 ) If the above has no effect, please contact your vendor or authorized service.
