Bicycle Wheel Design

The wheels of a bicycle are critical components that support the weight of the rider and any cargo being carried. Cargo bicycles require specific wheel designs to ensure durability and reliability when carrying heavy loads. In this chapter, we will discuss the key design considerations for bicycle wheels used in cargo bikes.

Wheel Size:Cargo bicycles require larger wheels than traditional bicycles to provide greater stability and support heavier loads. Common wheel sizes for cargo bikes include 26-inch, 27.5-inch, and 29-inch.Rim Design:The rims of cargo bicycle wheels need to be strong enough to support heavy loads without bending or warping. Cargo bike rims are often made from sturdy materials such as aluminum or steel, and may feature reinforced spoke holes or a higher spoke count.Spokes:The spokes of cargo bike wheels must be strong enough to support the weight of heavy cargo and provide stability when riding. Cargo bike spokes are typically made from stainless steel and may feature a thicker gauge or a higher spoke count for added strength.Hubs:The hubs of cargo bike wheels must be strong and durable to handle the added weight and strain of heavy loads. Cargo bike hubs may be made from materials such as steel or aluminum, and may feature sealed bearings for increased durability and ease of maintenance.Tires:Cargo bicycles require wider tires than traditional bicycles to provide greater stability and support heavier loads. Cargo bike tires may feature a higher volume or a wider width to provide increased support and stability.Electric Assist:Many cargo bicycles are equipped with electric assist systems to provide additional power when carrying heavy loads or riding up hills. These systems may include a motor in the hub of the wheel or an external motor connected to the crankset.In conclusion, cargo bicycles require specific wheel designs to support the added weight of heavy loads. By selecting larger wheels, reinforced rims and spokes, durable hubs, wider tires, and electric assist systems, designers can create cargo bicycles that are capable of carrying heavy loads while maintaining stability and reliability.
