Building My Neighbors A Sick Cargo Bike | Berm Peak

The Gist

A custom Mongoose Envoy cargo bike is built from the frame up to haul young kids and gear for a deserving neighborhood family.

Quick Overview

A custom Mongoose Envoy cargo bike is fully built and delivered to a local family with young children to help them easily haul gear and kids on rides. The build features hydraulic disc brakes, an upgraded drivetrain, a 3D-printed head badge featuring a custom 'Ride On' design honoring the family grandfather, and custom 3D-printed mounts for drink holders, a speaker, and a pump-slash-tail-light combo.

Key Points: The build starts with a Mongoose Envoy aluminum longtail cargo bike frame. Hydraulic disc brakes and a mountain bike derailleur are installed to handle the extra weight of hauling two kids. A custom 3D-printed head badge reading 'Ride On' is created to honor the family grandfather who was an avid cyclist. A custom 3D-printed Bluetooth speaker holder is mounted to the frame at a 31-degree angle so the speaker faces upward. Custom 3D-printed dual cup holders are secured to the rear rack using zip ties through integrated channels. A Flextail pump and tail light combo is attached near the rear using a custom 3D-printed mount with Clik valve adapters. A custom balance bike carrier is mounted to the rear rack to securely hold a Strider bike alongside woom helmets. The completed cargo bike is successfully delivered to the Baker family at a local restaurant to the excitement of the kids.

Context: Neighbors who frequently ride bicycles with their young children needed a reliable way to haul gear and toddlers. Seth from Berm Peak offered to build them a fully customized cargo bike under the condition that he had complete creative freedom over the project, dedicating the build to the memory of the children's grandfather who was a passionate cyclist.

Detailed Analysis

The project begins by stripping a brand-new Mongoose Envoy cargo bike down to its bare frame in the workshop to replace the stock components with higher-performance parts. Seth installs a longer stem and Redshift riser handlebars to accommodate taller parents, and upgrades the braking system to hydraulic disc brakes with internal frame routing for better stopping power. A mountain bike derailleur with a clutch is added to manage the long chain over bumps, and the stock kickstand is secured using custom 3D-printed blocks and hardware to support heavy loads safely. Customization includes printing a green 'Ride On' head badge that replicates a memorial tattoo shared by family members. For extra utility, custom 3D-printed brackets are designed and attached to hold a Sony Bluetooth speaker, dual water bottles, and a portable pump with a tail light. A specialized rear balance bike carrier is bolted onto the top rack to transport a Strider bike alongside woom helmets. The finished bike is ridden to a local gathering spot where the parents and children are surprised with the final build, resulting in an overwhelmingly enthusiastic response from the kids.
