The Growing Market of E-Bikes
According to
academic journal Taylor & Francis, electric bikes are “the largest and most rapid uptake of alternative fueled vehicles in the history of motorization.” By many accounts, it is estimated that by 2023, international sales of e-bikes will reach around 40 million units, worldwide. Currently, China is one of the most influential markets for electric bikes globally, as it is predicted they will sell 34 million units. The remaining units will be sold by Taiwan, Europe and a small but emerging market in the USA. Considering the rapid uptake and manufacturing of electric bikes, does it make a difference where they are made?
Where E-Bikes are Manufactured
Many electric bike companies don't actually manufacture their own product. Instead, they either design bikes to be built elsewhere or import and re-brand e-bikes that are manufactured by another company. There are many bike companies that design and create a bike with parts sourced from a global supply chain which are upheld by strict quality control. There are also many bike brands that simply buy wholesale from a manufacturer without strict quality control or deviation from the standard design.
With a few exceptions, almost all e-bike frames are manufactured in Asian factories- located either in China and Taiwan. What is the difference between these two markets? Most reputable companies in the U.S. use Taiwan-made frames, in fact, Taiwan is the biggest bike manufacturer in the world and they produce for some of the most well-known brands like Trek, Specialized, QBP, Tern- all of which have different models and frames that are recognizable for their quality. China mass produces cheaper bikes that are attractive to big buyers and generic brands.
One thing bike aficionados are aware of is the difference in labor and factory standards in China and Taiwan. Chinese factories manufacture lower quality frames that fall apart, may not ride as straight or precise and aren't as strict with quality control and waste management of production. If you're choosing an electric bike as an environmentally friendly alternative to a car; the irony would be buying one that pollutes its local factory environment.
European and U.S. Manufactured E-Bikes
The more expensive models are actually made in the US and Europe. However, as stated before, many bike brands don't manufacture the e-bikes. Riese and Muller are a popular German made brand that started out manufacturing in Taiwan but now produce their own frames. Raleigh is a UK based company but most likely get frames from Taiwan. Kalkhoff in Germany is designed and produced in Germany, adhering to certification standards and producing around 500,000 e-bikes every year. Brompton is another UK based company that manufacturers their frames.

Reise Müller Factory in Germany
The U.S. bike industry is experiencing a surge in production in the last few years. Assembly plants in South Carolina, Nevada, and other states are opening up. With Tesla's Gigafactory producing lithium-ion batteries, we can expect to see a widespread development of advanced electronic manufacturing in the U.S. Speculators think that with the increase in local battery production, battery prices could see a production in cost, which in turn would fuel more U.S. based e-bike companies.
E-bikes that are sold in the United States, Europe or Australia just to name a few are held to product safety regulations. Some regulations are specific to the entire assembly of electric bikes, such as European product safety standard EN 15194, while other regulations, for example, RoHS and the Low Voltage Directive, apply to batteries and other components.
Most mid to high end established brands make sure that their products are safe and compliant, and not just the frame. Important components like the gears, battery, motor, petals, handlebar, brakes, charger, tires, etc. are usually bought from outside suppliers, making the assembly of a high-quality bike the difference between putting together different scraps at a low price or ensuring that each component will work and has been tested.
Tawain Manufactured E-Bikes
The e-bike export market has historically been dominated by China, but Taiwan exports are catching up quickly, especially in the mid to high-end of the market while Chinese exports continue to stay at the low to mid range.
One of the biggest factories to export e-bikes to the US and UK is Giant, with 9 factories worldwide. A Taiwanese company started in 1972, Giant manufacturers their own bikes- including the carbon bikes, which is unique in the industry.

Giant Factory
Giant has a reputation for being the best manufacturer of carbon frame bikes. Interestingly, they buy their carbon in raw spools that look like carbon thread to make their own wide carbon sheets using their own resin formula. Additionally, they own their own aluminum mines and smelters! Research into the production process of each factory and the working conditions and quality expectations reveal precision and attention to detail. In addition to making their own bikes, Giant also makes or has made, bikes for many other brands such including Trek, Specialized [now part of Merida], Schwinn, and Bianchi.
China Made Bikes
China-made frames are used in generic brands and cheaper bikes. When you go into a reputable bike store that carefully sources their product, like Propel, New Wheel, they most likely sell high-quality bikes that are probably not from China.
The price of the electric bike is entirely based on the component composition, like which battery models and the type of motor, etc. Therefore, you cannot compare the prices between e-bikes, but rather compare sets of components against each other. What’s more, Chinese suppliers, including those in the e-bike industry, tend to lack strict internal quality guidelines. In practice, this means that most manufacturers basically use any components that are available unless otherwise specified by the buyer.
An interesting turn in events is the tariffs being enacted on e-bikes made in China. The E.U. has tariffs ranging from 80 to 170 percent, while the U.S. is considering a 25 percent tariff. What made Chinese e-bikes so attractive was the fact that they were lower-priced and mass produced, now that that advantage is drastically reduced, Taiwanese manufacturers are at the perfect crossroads to take over the market.
This Wikipedia list shows a list of popular and established e-bike companies and where they manufacture their product.
If you're in the market for an e-bike and wonder at the different costs for different brands, or if you are concerned that your super cheap bike will not last long, in this case, the old adage is true: you get what you pay for.

and yes for a while I was happy with it, but at 92 lbs I found it was to heavy if you were somewhere and your battery 
for 8 or 9 months and finally when I got a new controller it was a seven wire Quick connect system instead of a seven wire quick connect + two wires embedded deep in the controller surrounded by electric plaster. The new controller installation is not for the rookie electronics person this system requires a meltdown of the low heat plastic’s inside the old and new controller to get to the wires connects. This low heat plastic is part of the water 
proofing of the controller system and once removed from old controller wires connected to new controller you have to remelt the plastic and poor it back into the controller for water 
️ system that was like asking for their first born child personally I think 
the Chinese who make the ebike want let them have it. So now you know the nightmare of buying a high priced Chinese ebike. I only got 300 + miles before the controller went out just so you know that.
