The 123rd Spring Canton Fair 2018 officially begin

In the spring of 2018, the Canton Fair officially began on April 15. We warmly welcome you to visit our booth to visit our latest electric bicycle.

This first issue will be held from April 15th to 19th. 2018 Booth Number: 16.2E17.


Canton Fair(China Import and Export Fair) is the largest trade fair with the largest scale, the most complete exhibit variety, the broadest distribution of overseas buyers and  the greatest business turnover held in Guangzhou(Canton) China. Over 20,000 venders, about 100,000 buyers will attend the fair twice a year.

Electric bicycle flywheel

Electric bicycle flywheel.

Rotary flywheels are fixed with threads, and the teeth cannot be split, like nuts and bolts.
Rotary flywheel, its Jing wheel is integrated with the flywheel tooth piece, the entire flywheel is connected with the rotating drum through the thread. Usually due to the presence of the Jing-wheel mechanism, the rotary flywheel has a minimum blade size of only 14T, and it is difficult to make it smaller. Individuals also have the smallest blade 11T, which partially protrudes beyond the load-bearing portion, and the actual structural strength is limited. Because the rotary flywheel is connected with the rotary hub by means of threads, the structural strength is low, and there have been precedents in which a person who has trampled vigorously pedals down. Rotary flywheels have long since been eliminated in sport bike parts and are currently only used in civilian vehicles, and therefore there will no longer be better materials and processes.

specialized electric fat bike hub gear

A hub gear,internal-gear hub,or just gear hub is a gear ratio changing system commonly used on bicycles that is implemented with planetary or epicyclic gears. The gears and lubricants are sealed within the shell of the hub gear, in contrast with derailleur gears where the gears and mechanism are exposed to the elements. Changing the gear ratio was traditionally accomplished by a shift lever connected to the hub with a Bowden cable, and twist-grip style shifters have become common.

electric moped with pedals gear case

A gear case, also known as a chain case or chainguard, is an enclosure for the bicycle chain and sprocket assemblages commonly employed by utility bicycles. It serves to protect the cyclist from being soiled or trapped in the chain rings and tends to fully enclose the drive train. It may also contain an oil bath to keep the chain lubricated. Modern examples are usually moulded in plastic. Similar devices may be found in connection with chains used on larger vehicles and machinery.

lightweight foldable electric bike fork end

A fork end,fork-end,or forkend is a slot in a bicycle frame or bicycle fork where the axle of a bicycle wheel is attached. A dropout is a type of fork end that allows the rear wheel to be removed without first derailing the chain.

Track bicycle frames have track fork ends, on which the opening faces rearwards. Because they do not have dropouts, the chain must be derailed from the sprocket before the rear wheel can be removed from a typical track bike. Some single-speed bicycles intended for street or trail use are also equipped with track fork ends instead of dropouts.

buy cheap electric bike gear-shifting system

An electronic gear-shifting system is a method of changing gears on a bicycle, which enables riders to shift with electronic switches instead of using conventional control levers and mechanical cables. The switches are connected by wire or wirelessly to a battery pack and to a small electric motor that drives the derailleur, switching the chain from cog to cog. An electronic system can switch gears faster, and because the system does not use Bowden cables and can calibrate itself, it may require less maintenance.

cheap electric cycles derailleur gears

Derailleur gears are a variable-ratio transmission system commonly used on bicycles, consisting of a chain, multiple sprockets of different sizes, and a mechanism to move the chain from one sprocket to another.Although referred to as gears in the bike world, these bicycle gears are technically sprockets since they drive or are driven by a chain, and are not driven by one another.

ladies electric mountain bike crankset

The crankset (in the US) or chainset (in the UK), is the component of a bicycle drivetrain that converts the reciprocating motion of the rider’s legs into rotational motion used to drive the chain or belt, which in turn drives the rear wheel. It consists of one or more sprockets, also called chainrings or chainwheels attached to the cranks, arms, or crankarms to which the pedals attach. It is connected to the rider by the pedals, to the bicycle frame by the bottom bracket, and to the rear sprocket, cassette or freewheel via the chain.
