Weight
The heaviness of a BMX part, measured by weighing. It's worth noting that weight specifications for BMX parts can vary and may not always be precise. Several factors contribute to this:Manufacturer's weight specifications may be inaccurate or incomplete.The weight of two identical parts can also differ.We cannot weigh every individual part.For example, if there are handlebars in different heights, the manufacturer usually provides just one weight specification for all heights. When weighing two identical tires, you might get two different results.

The Surly "Big Dummy" Cargo Bike Frame + Fork Set - 26 Inch is Surly's analog longtail cargo bike: a month of groceries, lumber from the hardware store, kids or the pizza for the party, all up to 181 kg combined with the rider. The single-piece frame is stiffer and flexes less than a bolted-on tail.
The set includes the paint-matched Dummy Deck, the Dummy Rails with collars for passengers, the Big Dummy Bags (version 2.0) and an alloy center kickstand. The vertical dropouts have fender eyelets, tires up to 26 x 2.5" fit with fenders, and the frame is Rohloff compatible.
