COVID-19 Notice: The Asia Import Platform is designed to ensure that you can manage the importing process from anywhere – at a time when it’s impossible to visit suppliers and attend trade shows in Asia.
An e-bike is a rather complex system of mechanical and electrical components. While that can be said about many products, getting your product specifications right is critical when importing e-bikes from China.
Buyers in the US, Europe, and Australia need to be even more cautious. E-bikes, and their components, are regulated – and the consequences of non-compliance are serious. Let’s begin by taking a look at the technical aspects.
Components and product specifications
First of all, the price of the electric bike is entirely based on the component composition (i.e. certain battery models and brands are more expensive than others, 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 many suppliers basically use any components they have in stock – unless you explicitly “tell them” to use specific components. Let’s look into the most important specifications when buying electric bikes from China:
Gears are not “made in house” by e-bike suppliers. Like many other components, these are purchased from other suppliers. Manufacturing gears is not that simple, and replacing them is expensive. That’s the reason why most importers prefer to use brand name gears, from reliable manufacturers, such as Shimano.
That doesn’t mean you need to call up Shimano and arrange for them to supply your manufacturer in China.
They are already present in the country, and all respectable e-bike suppliers are already buying gears from established brands.
Selecting the right motor is not only about quality, but also regulations in your home country. Due to speed limitations, motor wattage is restricted in most markets. Below follows an overview:
European Union: 180W – 250W
United States: 350-750W
Most E-bike suppliers purchase motors from domestic manufacturers in China. That is not necessarily anything bad, but the supplier should at least be able to present documents showing compliance with directives such as CE and RoHS.
These are EU standards (thus not legally required in the US, Canada, or Australia), but acts as a sign of good quality.
The battery, usually a Li-Ion (Lithium Iron Phosphate), differs in terms of weight, lifespan, and capacity. Most batteries use battery cells from well-known brands, such as Panasonic, Samsung, and Sanyo. The supplier shall also be able to prove that the battery is compliant with relevant product regulations.
The key concern when selecting a charger is compliance with applicable electrical safety standards, in the destination market.
As in the case of batteries, a supplier shall be able to show compliance documentation, such as test reports and certificate of compliance, that is valid for the specific charger model you’re buying. There are plenty of poorly constructed and unsafe chargers in China. Low-quality chargers are potential electrical and fire hazards.
Most importers select a frame based on design, material (usually an aluminum alloy), and weight. The frame is often what sets suppliers apart in China. While all e-bike manufacturers purchase most mechanical and electrical components from subcontractors (e.g. gears from Shimano), many make the frame in-house.
It’s also possible to custom design frame. But, product customization requires investment in additional tooling such as molds. Don’t expect your supplier to finance this.
Other components and specifications
A bike frame with gears and a battery doesn’t add up to an entire e-bike though. Below follows a list of product specifications that you shall include on your sales agreement when buying electric bikes:
Fork (Material, Suspension type)
Rim (Material, Type)
Wheel size (Dimensions)
Tire (Material, Dimensions)
Controller (Brushless: Yes / No)
Brake (Type, Brand)
Foldable (Yes / No)
Logo (Type of print, colors, position, and dimensions)
Max Speed (e.g. 25 km/h for EU bikes and 32 km/h for US / Canada)
Loading Capacity (usually 90 – 120 kgs)
E-bike product safety standards and regulations
E-bikes, manufactured in or imported to, the United States, Europe, or Australia (and a number of other markets) are subject to product safety regulations. Some directives specifically regulate electric bikes (assembled product), such as European product safety standard EN 15194, while other regulations, such as RoHS and the Low Voltage Directive, apply to batteries and other components.
Far from all e-bike suppliers in China are able to make e-bikes that comply with EU and US regulations. In fact, I expect that no more than 20% of the e-bike manufacturers can show previous compliance with European, American, and Australian safety standards.
Only suppliers that are actively exporting e-bikes to these markets have an incentive to make compliant products. Most are selling their products domestically.
How do I know if an e-bike manufacturer can comply?
You should ask your supplier to provide test reports, valid in your country or market. You cannot apply ‘old’ test reports to your newly made batch of e-bikes, but you can assess if the supplier is capable of making compliant goods.
In addition, you should only select batteries and AC adapters from Samsung, or other known brands.
Established brands ensure that their products are safe and compliant. Hence, you will not need to get them tested or certified.
The requirements differ between countries, and it’s up to you to provide the label files to your supplier.
In addition to making sure that the product is technically compliant, and correctly labeled, you must gather a set of documents.
Most of these documents are ‘self-issued’, by the importer.
A few examples follow below:
Declaration of Conformity
Bill of Materials
List of applicable standards
AC Adapter datasheet
Lab test reports
Third-party lab testing is the only way to be sure that your e-bikes actually comply with the regulations in your country. As I said, you can avoid lab testing in part, if you select brand name batteries and AC adapters.
There’s another reason that client selected a bad supplier. They claimed that their frame weighed about 20% less than their competition. First of all, low-end suppliers don’t have access to cutting-edge composite materials. Secondly, never make a supplier selection based on a statement from a random sales agent, that you have never met.
Honestly, don’t take them by their word even if you meet them.
b. Ensure that the manufacturer uses these components when assembling the e-bike
Battery shipping restrictions
There are restrictions in place for shipping batteries of various kinds. You need to make sure that your supplier is able to provide a document specifying the brand, model, and type of battery that comes with your electric bikes. Failing to supply such a document may result in your cargo being refused exit in the Port of Loading, in China, or refused entry in the Port of Destination.
List of E-bike manufacturers in China
A few years ago, we were sourcing electric bike suppliers in China for a European client. We presented a number of well-established suppliers, also compliant with western product safety regulations, for the client to choose from. But.. the client managed to find a cheaper supplier, one that offered “the same product for a price 10% lower”.
Later on, it turned out that the “cheap supplier” didn’t live up to the buyer’s expectation. It turned out to be a highly disorganized and dusty workshop that basically put together whatever scrap they could find. The buyer lost a lot of money, and the “cheap deal” turned out to be not much more than a mirage.
Keep reading and I’ll explain why there’s such a vast quality difference between suppliers.
E-bike manufacturers are not making every single component in-house. At most, they manufacture the frame and a few metallic parts, while other mechanical and electrical components are purchased from subcontractors.
Assembling e-bikes is not rocket science. But managing a supply chain of high-quality components, in China, is not far from it. The components make the e-bike, and that’s why you shall only work with medium to large scale manufacturers, that are capable of managing such a supply chain, rather than disorganized workshops.
So, where you find these suppliers? Like many other vehicles and parts manufacturers, E-bike suppliers are mainly located in Zhejiang province. In case you plan to go there, you’ll likely end up in any of the following cities:
