There's another organisation at this address- Leeds Bike Mill. They are a not-for-profit worker co-op community interest company offering bike maintenance training courses and selling refurbished second hand bikes. Their website is www.leedsbikemill.org. They don't currently have regular opening hours. Thanks
Added Leeds bike mill. I don't think there's enough granularity in the map tags to reflect all its services, but the key details are there.
