Ohio City Bicycle Co-Op

The Ohio City Bike Co-​op is a non-​profit organization that helps Clevelanders get out and riding on a bicycle to improve their resourcefulness and health.
I visited the OCBC recently with my son, but they did not have a bike that fit him. But they were willing to measure him vs the bikes they did have in stock. They have a ton of used bikes for sale at reasonable rates.
The location is in the flats on the Cuyahoga River and is beautiful.
If you need a bike, check here first!

Once mom gifted me her old bike, it was time for fiancé to get one. We called here first and they understandably explained that selection is limited at the end of summer (we came around in August). They do most of the refurbishing over the winter, and spend the summer months doing classes for kids. They asked for height and was able to describe the types and bikes available that would be a good fit.
Come down, they’ll let you take some test rides, and you can check out any hand-​me-​down low cost bike accessory you can think of. Bonus — you get a free tune up and they offer riding classes for traffic signals/​safety.
Don’t miss the hammock outside made out of bike tubes. Resourceful!

I volunteered at Ohio City Bicycle Co-​op through HandsOn NEO. It is a great place! The staff/​volunteers are very friendly and not intimidating. All their bikes were donated to them from individuals, schools, city, etc. Then they are cleaned, and fixed if needed. You can buy or rent the bikes. They aslo have group rides.

This is a really neat group of people brought together by a mutual love of /​need for biking. Their mission is to educate people about biking — everything from how to tune and repair a bike for daily commutes, to advocating for bike friendly trails and events in the Cleveland area. They even rent bikes if you just want to try it out.
I went there when I was just starting to look into biking. They helped me determine which size and type of bike most suit my needs. They have a decent selection of bikes for sale at fair market value — don’t expect to find any steals — and a neat program where you can volunteer your time in exchange for use of the shop and to subsidize purchases (at $ 5/​hr)
The building is a little run down and easy to miss, so don’t be surprised if you have to drive by a couple times to find it.
tl;dr: This is a recommended starting point if you’re interested in becoming a bike hobbyist or if you need a bike for commuting.
