1. Read this manual !
Please read all information in this manual carefully to gain maximum performance, safety and enjoyment from your Lafree Twist electric bicycle.
Congratulations! You have just pedalled into the exciting world of electric power assistance for bicycles. In addition to being a full-featured bicycle, the Lafree Twist has an integrated on-board electric power assist unit. The assisted pedal system is easy to use and understand. However, due to its sophisticated technology, it is extremely important that you follow the directions for their operation carefully and completely. Failure to do so could cause damage to the motor, energy set (battery pack/charger unit) or the entire bicycle
Even though Lafree Twist functions as a standard bicycle, you should still review the chapters on bicycle operation, especially if you haven’t ridden/owned a bicycle within the last 10 years. Component performance and configuration has changed dramatically, and while they are easy to use and understand, they may not look quite the same as what you are familiar with! Taking a few moments now to understand Lafree Twist’s operating procedures will help you get the most out of every ride.
Please read section 5.1: “Battery detachment, charging and installation” before operating Lafree Twist’s electric powered functions. Lafree Twist’s battery must be charged completely before the motor (power assisted pedalling) can be operated.

2.4 Position of the serial numbers
Please record Lafree’s bike serial number and battery serial number for future reference. The serial number of the bike is stamped into the left rear “dropout” of the frame. The dropout is the piece of frame that holds the axle of the rear wheel (see fig. 08).
Battery’s serial number: see fig. 09.

3. Fit and safety
3.1 Fit
Make sure the bike fits. A bike that’s too big or too small for the rider is harder to control and can be uncomfortable or dangerous.
Frame size. Your dealer will have recommended the best frame size for you, based on the information provided. If you picked your own bike at the dealer shop, your dealer took the time to fit you to the correct frame size at the time. If someone else selected the bike for you, as a gift, for example, it’s important for you to make sure that it fits before you ride it.
Standover height (see fig.10). It is the distance from the ground to the top of the top tube at the point where your crotch would be if you were straddling the bike by standing half way between the saddle and the handlebar stem. To check, straddle the bike. If your crotch touches the frame, the bike is too big for you. A bike you ride only on-road should offer a minimum clearance between top tube and your crotch of 2.5 to 5 cm. (one to two inches). A bike that you’ll ride off-road tracks should have 7.5 cm. (three inches) minimum clearance, whilst a mountain bike for use on tough terrain should offer 10 or more cm. (four or more inches) clearance.
Pag. 7.
3.2 Saddle position
Correct saddle adjustment is important in getting the best performance and comfort from your bicycle. a. Up and down adjustment .
Your leg length determines the correct saddle height. To check for correct saddle height:
− sit on the saddle
− place one heel on a pedal
− rotate the crank until the pedal with your heel on it is in the lowest position and the crank is parallel to
the seat tube.
− your leg should be almost straight. If not, your saddle height needs adjusting.
To adjust the saddle height, loosen the seat post fixing bolt (see fig. 11a) and move the seat post up or down as required. Then, make sure that the saddle is parallel to the top tube of the bike, and retighten the seat post fixing bolt tight enough so that you cannot twist the saddle out of alignment. Check the adjustment as described above. The seat post shall NOT project from the frame beyond its Minimum Insertion mark (see fig. 11b).
NOTE: In order to guarantee the quality of the frame, Giant uses different types of seat posts for gents and ladies bikes Lafree Twist. The difference between the 2 types seat posts is the position of the Minimum Insertion marks. The minimum insertion length of the seat post for the ladies bike is 15 cm. The minimum insertion length of the seat post for the gents bike is 10 cm. Keep this in mind when you need a new seat post. Be careful when you switch seat posts of ladies and gents bikes.
b. Front and back adjustment .
To find the most comfortable position, loosen the saddle clamp and adjust the saddle forward or back to suit you. Retighten the saddle clamp. (See fig. 12).
c. Saddle tilt adjustment .
Most people prefer a horizontal saddle, but some riders prefer to have the saddle tilted up or down a little. Adjust the saddle tilt by loosening the saddle clamp, tilting the saddle to the desired position, and re-tightening the saddle clamp. Very small changes in saddle position will make a big difference. Make only one change at a time, and only in small steps until you have found your most comfortable position.
WARNING: After any saddle adjustment, be sure to tighten the saddle adjusting mechanism properly before riding. Periodically check to make sure that the saddle adjusting mechanism is properly tightened.
Pag. 8.
3.3 Handlebar height and angle
a. Handlebar stem height.
You can raise or lower the handlebars. Loosen the stem height adjuster bolt (see fig. 13) by turning it anti-clockwise three or four turns . If the bolt rises but the stem doesn’t move, tap the bolt carefully down, using a plastic or wooden hammer. Set the handlebar stem at the correct height and perpendicular to the front wheel. Fasten the bolt to the correct torque, so that you cannot twist the stem and handlebars (see
section 8.3 “Tightening torque”). The Minimum
Insertion mark must NOT be visible.
Note: In order to guarantee the quality of frame and fork, Giant uses different types of handlebar stems for gents and ladies bikes Lafree Twist. The difference between the 2 types stems is the position of the Minimum Insertion marks. The minimum insertion length of the stem for the ladies bike is 80 mm. The minimum insertion length of the stem for the gents bike is 65 mm. Keep this in mind when you need a new handlebar stem.
b. Handlebar angle.
By tilting the handlebar you can direct the grips more upward or downward. This is a matter of personal taste. Loosen the bolt at the front side of the handlebar stem (handlebar clamp bolt). Tilt the handlebar to the required position. Fasten the bolt to the correct torque (see section 8.3 “Tightening torque”). Check and if required adjust the position of the brake levers.
c. Handlebar stem angle.
The adjustable handlebar stem allows you to adjust the angle of the handlebar stem extension. Loosen the inclination bolt and set the extension to the required inclination. Fasten the bolt to the correct torque (see section 8.3 “Tightening torque”). Check and if needed adjust the angle of the handlebar and the position of the brake levers.
After changing the position of the handlebar or the stem, check to make sure that the handlebars can rotate freely in both directions without the brake cables catching or binding on anything. It is essential to thoroughly check that your bars and stem are tight and cannot be moved after you have made any adjustments.
3.4 Safety equipment
3.4.1 Lights Lights are important safety devices which are designed as an integral part of Lafree Twist. If you ride your
bike after dusk, you must turn on the lights so that you can see the road and avoid road hazards; and so that others can see you.
Pag. 9.
3.4.2 Reflectors Reflectors are important safety devices which are designed as an integral part of Lafree. The reflectors are
designed to pick up and reflect street lights and car lights in a way that helps you to be seen and recognised as a moving bicyclist.
Caution: Check reflectors regularly to make sure that they are clean, straight, unbroken and securely mounted. Have your dealer replace damaged reflectors and straighten or tighten any that are bent or loose.
3.4.3 Helmet Our advice is to wear a good quality helmet at all times whilst riding your bike.
3.5 Mechanical safety checks
3.5.1 Nuts & bolts Inspect the bike closely from front to rear for any obvious signs of worn or broken components. Grasp the
handlebar with both hands and lift the front wheel off the ground 5-10 cm. (two or three inches), then let it drop firmly on the ground while still holding the handlebar. If anything sounds, feels or looks loose, do a quick visual and tactile inspection of the whole bike. Try to find the source of noise or any obvious loose components, and secure them. If you’re not sure, ask someone with experience to check, or take your Lafree Twist to your authorised Lafree dealer.
3.5.2 Tyres & wheels Check proper tyre inflation by placing your hand directly on top of each tyre individually. With a straight arm
and direct downward pressure, push on the tyre with downward body weight and watch the spot where the tyre is contacting the ground. There should be very little tyre compression. If your tyres need inflating, use a standard bicycle floor pump (see section 6.6.1: “Tyres”). If you must use a high-volume compressor like those found at automotive service stations, add air in small amounts as these compressors are designed to fill auto tyres which have much larger volumes than bicycle tyres. Adding too much pressure all at once could cause the inner tube to explode, which can cause severe damage to the tyre and serious injury.
Spin each wheel slowly and look for cuts in the tyre’s tread and side wall. Replace damaged tyres before riding the bike.
Spin each wheel and check for brake clearance and side-to-side wobble of the rim. If a wheel wobbles side to side or contacts the brake shoes, take the bike to a qualified bike shop to have the wheel aligned.
CAUTION: Wheels must be “true” (aligned) for the brakes to work effectively. Wheel truing is a skill which requires special tools and experience. Do not attempt to true a wheel unless you have the knowledge and tools needed to do the job correctly.
