Battery and cable connections

The battery and cable connections are crucial components of your Stealth Bomber electric bike build. Here's a detailed guide to help you with these aspects:

Battery Selection:

When choosing a battery for your Stealth Bomber electric bike, consider its voltage, capacity, and compatibility with your motor. The voltage of the battery should match the motor's requirements. For instance, a 48V battery is typically used with a 1000W motor. The battery's capacity, measured in Ampere-hours (Ah), determines how long the bike can operate before needing a recharge. A higher Ah rating indicates a longer runtime. Ensure the battery size fits the casing dimensions of your Stealth Bomber frame, which are 330 x 202 x 140 mm, providing ample space for a large battery pack.

Cable Connections:

The Stealth Bomber frame offers a lot of space for cable connections during the assembly process. All cable connections can be neatly routed inside the cover of the controller. This keeps the cables protected and gives the bike a sleek, tidy appearance. Ensure that you follow the manufacturer's instructions for connecting the cables to the controller, motor, lights, and any other accessories you plan to install.

Battery Charging and Management:

Consider installing a charger inside the frame to allow for convenient charging anywhere with access to a power outlet. This eliminates the need to remove the battery for charging. Additionally, think about incorporating a battery management system (BMS) to protect your battery from over-discharge, over-voltage, and other potential issues. A BMS can help balance the cells in your battery pack, ensuring optimal performance and longevity.

Switches and Customizations:

You can install switches to control the headlight and tail lights independently of the bike's main power. This allows you to turn the lights on or off without having to turn the bike on or off. Additionally, consider adding USB charging ports to power your electronic devices while on the go. These customizations enhance the functionality and versatility of your Stealth Bomber electric bike.

Safety Considerations:

Always prioritize safety when working with batteries and cable connections. Ensure that all connections are secure and properly insulated to prevent short circuits and potential hazards. When modifying the electrical system or unlocking higher speeds, such as in "competition mode," exercise extreme caution. Refer to online forums and communities for insights and advice from experienced builders.

Wheels and suspension

When it comes to wheels and suspension for your Stealth Bomber electric bike, there are a few things to consider. Firstly, the suitable wheel size for this bike is 26x3.0" or 26x4.0". You can choose from a variety of wheel options available in the market, including those designed specifically for electric bikes, such as the 72V15000W Rear Wheel with a 200Amp Sabvoton Controller and Tektro Hydraulic Disc Brake.

For suspension, a full suspension setup on an electric bike can provide superior comfort and increased safety by ensuring you stay connected to the road, regardless of the terrain. This can be particularly important if you plan to ride on uneven surfaces or off-road trails. The suspension system will absorb shocks and vibrations, providing a smoother ride.

Additionally, consider the weight of the bike, especially if you're planning to include a robust steel frame, as this will add to the overall weight. The Stealth Bomber, for example, weighs around 116 to 120 pounds, which is considered heavy for an electric bike. This weight distribution can impact the choice of suspension setup, as a heavier bike may require a more robust suspension system to handle the additional load.

Finally, think about the type of riding you'll be doing. If you're primarily commuting and riding on urban roads, a front-wheel-drive setup with a single motor might be sufficient. However, if you plan to tackle off-road trails or desire more power and traction, you might consider a two-wheel-drive setup, as mentioned by some Stealth Bomber builders, which provides better handling and performance in various conditions.

Seat and handlebars

The seat and handlebars are key components of your electric bike. You can choose between a dirt bike-style seat and a bicycle-style seat. The former is more comfortable for long rides, but the latter is more practical and less likely to draw attention. The dirt bike-style seat is also more expensive. If you are planning on using your bike for off-road riding, a dirt bike-style seat may be preferable.

The handlebars are another important consideration. You can choose between a flat bar, a drop bar, or a riser bar. A flat bar is the most common type of handlebar and offers a comfortable, upright riding position. A drop bar is often used for racing and provides a more aerodynamic position. A riser bar positions the handlebars higher than the seat, which can be more comfortable for some riders.

When choosing a seat and handlebars, it's important to consider the type of riding you'll be doing and your personal preferences for comfort and style. Make sure to select options that are compatible with your bike's frame and any other components you've chosen.

You can find a range of seats and handlebars online, with prices varying depending on the quality and brand. Some sites offer complete kits for the Stealth Bomber, which include the frame, seat, handlebars, and other necessary parts. These can be a great option if you're looking for convenience and compatibility between parts.
