DIY E-Bike Conversion Kits on a Budget: Factory-Direct vs. Premium Brands (Real-World Tests)

When purchasing an e-bike conversion kit, many consumers instinctively favour big brands, believing that they can guarantee higher quality and reliability. However, this mentality often leads to paying a ‘brand premium’ – many smaller brands offer the same or even better performance at a lower price. Here’s why it may be wiser to choose a smaller brand, supported by a comparison of high-priced kit with affordable alternatives.


**1. Big brands’ high prices stem from marketing, not quality enhancement **

Big brands invest heavily in advertising campaigns, celebrity endorsements and market positioning, costs that are ultimately passed on to the consumer but do not necessarily result in functionality enhancements. Example:

  • Skarper Disc Brake Conversion Kit (approx. $1,171): claimed to be a lightweight, high-performance solution to motorisation by replacing the rear disc brakes. Despite the novelty of the technology, its price is well above that of many complete e-bikes, mainly due to the Olympic Champion endorsement and a marketing strategy aimed at a niche market.
  • Swytch Front Wheel Drive Kit (Pro version around $497): Despite the selling point of ‘three-step installation’ and minimalist design, the Tour version has a battery capacity of only 196Wh and a range of 100km – parameters comparable to those of unbranded kits made in China. These parameters are comparable to those of unbranded kits produced in China, which are priced 50-70 per cent lower.

These cases show that the ‘story’ of big brands often hides the lack of technical value.

Smaller brands achieve quality benchmarking through direct production

Many small manufacturers focus more on material quality and core technology than on branded packaging. Example:

  • Hydraulic Damping Kits: big brands such as Xiaomi M365 Pro Fork Damping Kit emphasise compatibility with specific models, but unbranded alternatives (e.g. 8.5’ Hydraulic Damping Kit) use the same materials (e.g., urethane wheels, hydraulic damping system) at 30-50% lower prices.
  • Battery & Controller Kit: Although the Xiaomi Original Battery BMS Protection Plate Kit relies on a brand premium, comparable unbranded products (e.g., 36V LCD+Throttle Kit) are CE/ROHS certified and come with a warranty, and are no slouch when it comes to safety.

Factories like ours (ruying) reduce costs through a direct-to-consumer model and produce kits that equal or even exceed the performance of the big brands and are certified.


3. Price Comparison: High-Priced Kits vs. Affordable Alternatives

High-priced branded kitsSmall-branded alternatives
Skarper Disc Brake Kit ($1,171)Universal Rear Shock Kit ($171–214)
Swytch Pro Kit ($497)36V Brushless Motor + Controller Kit ($143–214)
Clip Friction Drive Kit ($607)Polyurethane Silent Wheel + BMS Combo Kit ($114–171)

The price difference often exceeds 300%, but the technical differences are minimal.


4. Customisation & Flexibility Advantages

Smaller brands excel at meeting individual needs, which is difficult to achieve in the standardised production of larger brands:

  • Battery Upgrade: e.g. Changzhou Extraordinary Intelligent Technology* supports customisation of 48V to 72V battery capacity, whereas branded kits such as Segway Ninebot restrict users to fixed configurations.
  • Multi-Voltage Compatibility: universal controllers (e.g. 24-48V 350W Brushless Controller) are adapted to a wide range of vehicle models, while branded products such as Dualtron 3 Vacuum Tire Kit are limited to specific systems.

5. Case Study: The Triumph of Small Brands

Taking Changzhou Sailo Electric Technology Co. as an example, the overseas-focused manufacturer offers an 8-inch controller + display kit priced at only $171–214, 40% lower than similar products from Alibaba, and includes waterproof and anti-theft features. In contrast, brands such as Skarper and Swytch are mainly targeting the high-end market in Europe and the US, ignoring the demand for cost-effective products in developing countries.


Conclusion: Value lies beyond the trademark*

While big brands dominate the market view, smaller brands offer equal or even better solutions by streamlining their operations and being transparent about their technology. By choosing factory-direct suppliers and verifying certificates, consumers are well positioned to get high-quality e-bike kits at a lower cost.

For example, the Swytch Pro kit ($497) does not perform as well as the Xiamen Saichun 1000W motor kit ($210) – which supports both mountain bikes and commuter bikes and is 70% less expensive. Ultimately, the choice depends on whether you’re willing to pay for innovation or a brand premium.
