The Pro's Closet

The Pro's Closet Inc. (TPC) is an e-commerce company that buys and resells new and pre-owned bicycles and cycling equipment, including road, mountain, gravel/cyclocross, triathlon/TT, fat and e-bikes, plus frames, wheels, tires, components, accessories and apparel. Its core offering is a Certified Pre-Owned (CPO) process in which mechanics inspect, restore and service each bike at the company's Colorado headquarters, including washing, replacing wear items such as tires and chains, and inspecting and servicing the drivetrain and wheels. Buyer-side programs include 30-day returns, a Bike Finder tool, Ride Guide consultations, a rewards program and, historically, Guaranteed Buyback and a Carbon Frame Warranty.

On the supply side, TPC purchases bikes and accessories from manufacturers, retailers and individuals, and offers consumers cash offers, consignment and trade-in, with offers on submitted bikes, frames or wheels quoted within 48 hours. The company describes itself as the world's largest retailer of pre-owned bicycles and positions its model within "recommerce" or the circular economy. Alongside its website, TPC operates a retail store in Thornton, Colorado, north of Denver, which it describes as the Denver metro area's largest bike shop and which carries its full online inventory of new and Certified Pre-Owned products.

Founding story

Founder Nick Martin raced mountain bikes professionally in Colorado in the early 2000s after business school in Wisconsin, and sold his sponsor equipment on eBay at the end of each season to cover living expenses. He began reselling teammates' and other cyclists' gear from his home, which gave the business its name, and the eBay store became eBay's largest store for used cycling equipment. In 2017, after raising seed capital to buy bike inventory directly, Martin and a small team began certifying and reselling bikes, then moved off eBay to launch a direct-to-consumer branded website in order to own customer data and build an integrated reconditioning and fulfillment operation.

Business model

TPC acquires bikes, frames, wheels and accessories from manufacturers, retailers and individual cyclists through cash purchases, consignment and trade-in, reconditions them through its Certified Pre-Owned inspection and service process, and resells them online and through its Thornton, Colorado retail store. Investor commentary describes the company as owning its supply chain end to end, with every step digitally documented from valuation and sales through inspection and processing, and as operating both direct-to-consumer and B2B channels with bike OEM and retail partners.

Revenue comes from retail sales of reconditioned pre-owned and new bikes, frames, wheels, components, accessories and apparel, sourced via outright purchase or taken on consignment, sold through its own website and its Colorado retail store.

Traction

TPC reported more than 130% year-over-year topline revenue growth as of September 2020, and Edison Partners cited sales growth of more than 175% year-over-year in the 18 months after the DTC site launch with a 13-day sell-through rate and an NPS of 78. In May 2021 the company reported Q1 sales double those of 2020, revenue that had more than quintupled, and an expectation of doubling in size again in 2021. The company's About page cites more than 160,000 customers served and more than 46,000 bikes sold since 2006.

Latest developments

The company continues to operate its e-commerce site and Thornton retail store, promoting Certified Pre-Owned inventory, a refined packing and shipping process, and seasonal campaigns. An April 2025 company blog post referred to an ongoing effort to rebuild and diversify the business and to a new chief revenue officer and head of marketing among its leadership.
