I ask you: Which bike is better performance, but not too expensive
I personally think that Giant bike is very good very robust, with two years have not a thing wrong. Is a bit expensive frightened thief misses.
There Amini, permanent mainland birds, urban wind is good as long as you choose a particular brand reputation, the volume of production of the professional manufacturers of electric bicycles, electric have cars do not have to worry about performance. You pay for, or are afraid to spend money to buy a good point. [With Buying Guide]
Selection of the bike, consider the following: 1, the fastening nut of the bicycle must be tightened, and are not loose and fall off. 2, the flexible operation of the rotating parts do not have to sit, stay rigid phenomenon. Such as: front and rear wheels to rotate flexibly, and not lying around and up and down, the wheel will be stopped when the light should do before and after the swing, can not suddenly stop moving. Around the rotation should be flexible and comfortable steering wheel, pedals and crank shaft should be strengthened, not separate each other, and the flexible rotation. 3, the speed range response file in the correct speed, variable speed position clear,
bicycle chain length, there is no center hole. 4, the chain suitable elastic, flexible operation. Repeated shaking hands forward reverse crank sprocket, chain, flexible in use, without chain and jump off phenomenon. 5, with both hands before and after the upper part of the saddle, saddle with one hand forced under pressure, Front-end saddle remain. Level with both hands and put the saddle, the saddle can not be rotated. 6, selection of brakes and braking systems: both hands on the wheel, respectively, both before and after the push-pull brake bikes around, this time not at the wheel, lever, the brake system must be able to quickly reset. 7, the surface of the parts must be clean, no stains, rust, brand stickers must be complete, clear, no sharp edges, burrs, etc., such as fenders and chain should not be difficult to feel the edge of the treatment, should inhibit other rope end and be provided with protective kits and so on. 8, the observed numbers of parts or labels. In general, the good parts labeled and marked clearly mark a distinct pattern of fine, while the lesser are rarely noticed or rough. �� Third, the choice of electric bicycles in addition to the above conditions should be in addition to the following points: 1 switching various parts of sensitive and reliable. 2, speed stable and reliable. Slowly turn the speed control lever, the engine should be a good start, accelerate, release the handle, the handle can quickly recover, even slow the engine. 3, the fast and reliable braking. Rotational speed control lever, the engine is running, squeeze the throttle, the engine without power when the current display, you can display returns to zero. 4, the battery is easy disassembly. The weight of lead-acid batteries generally about 13.5kg, the daily disassembly, so the location of the battery must be suitable for their bodies. �� Fourth, use and maintenance: pay attention to carefully read the instructions, understand the function of the cycle, with particular attention to the case. First, pay attention to hygiene, especially after contact with water must immediately clean winter salt, or very susceptible to corrosion of metal parts, coating aging off. Steering wheel and seat are adjustable to adjust if necessary to ride, the second is to pay attention to the maximum height setting. Saddle and handlebar riser pipe be registered with the safety line from the bottom of the seat tube diameter is generally 2.5 times, which is the maximum height adjustment, safety line should never be exposed. New juji period, the entire vehicle checked adjusted. Then mount and lubrication is essential. Check all fasteners should be loose, transmission parts must be flexible, focus on the chain lubricated oil to wipe the spill pay the flywheel can point a little oil. Tires for a good, otherwise it will affect the comfort and life. Braking is the fundamental guarantee of security, but should always make sure they find a problem that needs to be adjusted or repaired immediately.
