An annual Best Of winner, this Cass Corridor shop sells refurbished bikes and provides repair services on the cheap in order to promote its three-pronged mission: youth development, sustainable practices and community access. To that end, the Hub and the nonprofit arm that it supports, Back Alley Bikes, offers youth and adult mechanics classes, volunteer opportunities, a youth Earn-A-Bike program and community rides. The shop also works with other local bike projects to recycle old bikes and bike parts — be on the lookout for their bike racks crafted from retired bike frames at spots around Detroit. Check the website for weekly updates regarding classes, youth programs and other community news.
