SP found in 2007, based in Taichung, Taiwan.
Mass production for digital camera shutter has been launched. Owing to requests from customers for customized optical tilt inspection equipments, we successfully developed user friendly, highly precise and efficient inspection equipments and sold to some of Taiwan top 10 electronic companies. With advanced micro electronic technology, we successfully developed mini shutter for mobile phone application in end of 2007.

Considering our leading electronic mini motor technologies, we started to develop a new, efficient and advanced dynamo for hub application.

During the tough developing period, SP design team consistently persisted in its perfection commitment, and successfully created a brand new dynamo invention. This is called polar series alignment dynamo.

In Oct 2008, we cooperated with Formula engineering Inc and announced the first generation dynamo hub.

In March, the first generation dynamo hub with avant–grade shape and light weight was awarded as annual innovative products in 2009 Taipei bike show.

In July, we launched dynamo hub mass production.

In December, we successfully developed a smart switch mechanism on dynamo hub. By switch function, SP switchable dynamo hub can be rotated as free as normal hub when switching to power off mode.

In March, the world’s first switchable dynamo hub was awarded as annual innovative products in 2010 Taipei bike show. 

In June, SP announced the world’s first fish-eyes dynamo headlight by applying plastic aspheric optical lens, which can minimize lighting energy loss and enhance led lighting efficiency.                                                                                                                                  
In July, we joined Taiwan bicycle optical and electronic union as a member to cooperate with other partners in advanced product developments.

In August, Shimano officially licenses Centerlock disc brake patent to SP, announcement of the PD–8X, for QR15mm, 6 bolt disc brakes. PD–8X is the most efficient dynamo with 78% efficiency at 15km/h.

In January, announcement of the PL–8X, for QR15mm, centerlock disc brakes. In April, SP moves to a new factory 10 minutes away from old factory. Also located in Taichung.

In August, announcement of SP 9 series which is the new lightest and smallest dynamo hub group on the current market. The SV–9–F, for example, weights only 299g and max hub diameter is only 50mm.

In Auguest, to improve the attractiveness of our hub dynamos to a broader audience, we have developed a centerlock version of our 9 series hub dynamo i.e. SL–9 (weight 323g).

In Oct 1st, SP stopped the cooperation relationship (global distributor) with KT. And SP started to sell dynamo hubs to all global partners directly.

In March, we announced QR12 thru-axle hub i.e. PD–8X–M (428g, for disc brake) and PL–8X–M (428g, for centerlock brake).

In April, we announced PD–8X–110 as the boost hub (QR15 thru-axle, OLD110mm, for 6 bolt disc brake).

In January, we announced PD–8X–150 as the hub for snow bike (OLD150mm). The chase of ideal perfection is always the goal! In addition, we upgraded all 8X series, especially for bearings. Therefore, from January 1st, 2017, all 8X hubs from SP are all new version. Good functions with excellent durability.

We only make the best. We continue developing excellent devices for all riders... Stay with SP and you will be surprised by our next generation device...
