All fitness levels are welcome to come spin for a cause at CycleBar Providence. Proceeds from this “ride” benefit ecoRI News’ environmental journalism. This 45-minute charity ride will be followed by an informal meet-and-mingle with fellow riders. A prize will be awarded to the rider who registers the most friends — and all riders will be eligible for a separate raffle with prizes that include yoga passes, Providence Friars tickets, and ecoRI News T-shirts. Tickets are $30, and proceeds benefit ecoRI News.
