Whether converting a traditional bicycle or constructing a frame from scratch, crafting an electric bike tailored to your specifications is an exciting prospect. However, taking all specifications into account from the start helps avoid costly mistakes or dissatisfaction down the road. This article provides an overview of critical elements to evaluate in your custom build, from frame material options and gearing selections to compliance with local regulations.

1. MOQ (Minimum order Quantity)

The minimum order quantity, usually 100 bikes, is meant to help manufacturers achieve economies of scale in production. This allows them to spread fixed costs like equipment and facility costs over a larger number of units. However, it can disadvantage small volume customers who may struggle to meet the MOQ.

2. Frame

Frames come in various sizes, materials like aluminum, steel or carbon fiber, and styles like step-through or folding. Think about your height, weight limits, durability needs and intended uses. Mountain bike frames offer more ruggedness than road bike ones.

3. Basket and Rack

If cargo carrying is important, choose racks and baskets compatible with your bike and frame. Front/rear mounting points, weight limits and loading positions all affect stability. Installation may require frame modifications. You need to communicate this design with the factory in advance.

4. Battery

When considering electric bicycle batteries, it's crucial for buyers to pay attention to certain essential factors. These batteries are specifically crafted to be detachable components that seamlessly connect to the bike, enabling easy off-board charging. Reputable manufacturers prioritize sourcing battery cells from well-established leaders such as LG, and Samsung. These companies are renowned for their reliable lithium-ion performance and stringent safety controls.

5. Motor

High-torque geared or nakeded hub motors provide acceleration from stops but top-out at around 25mph. Mid-drive units mimic the feeling of a traditional bicycle better and can achieve 28mph, but add complexity. Motors are rated by peak and continuous watts - higher wattage improves hill climbing but shortens battery life.

6. Shifter and derailleur

For an OEM producer with a 100 bike MOQ, integrated gearing options simplify assembly over derailleur systems. Many brands choose Shimano, Because Shimano provides easy-to-use gear shifts and derailleur. Alternatively, a single-speed chain for simple reliability may suit casual riders. Consider components suited for cargo or mountain terrain. Routing cabling neatly is important for a polished look.

7. Lead Time

As an established OEM ebike manufacturer, promising delivery 2-4 months out allows sufficient time for bulk production while meeting typical customer expectations. Sourcing frames, parts and batteries in bulk directly from ebike manufacturers cuts costs compared to distributing separately ordered components yourself. Keeping a stock of commonly specified parts on-hand further reduces lead times.

8. Ebike Laws

Understanding and complying with electric bicycle regulations is paramount for any manufacturing company. Laws vary significantly between jurisdictions, making it the manufacturer's responsibility to educate themselves and their customers. It's prudent to purposefully design bikes well below the legal power and speed limitations defined by class levels.

For example, in many places Class 3 ebikes are allowed with motor assistance up to 28mph. However, intentionally capping motor output at around 20% less than this maximum, say 25mph, provides a valuable buffer should any given bike briefly exceed the limit under certain conditions. Exceeding statutory speeds, even temporarily, leaves room for legal consequences if stopped by law enforcement. 

Final Thoughts

By thoroughly evaluating end-use customers needs and considerations across these various categories, you can disign high quality, versatile electric bicycles at scale for diverse applications. Focusing on quick turnarounds, competitive pricing through economies of scale and compliance can lead to many satisfied repeat customers.
