Shimano Ultegra drive train Minor wear and tear About us: Zummobike is a 501 c3 organization that advocates for elementary students in the Norristown and Landsdowne school districts via a reading incentive program called read to ride. The majority of inventory of donated bikes are repaired, awarded to our readers or resold by our home grown elementary and teenage mechanics. For more information and to view our inventory, visit us at Zummobike.com . Why buy a bike from Zummo. No need to deal with the experience of going to someone’s house. In addition to looking at the bike you have in mind, you will be able to evaluate others. All bikes, purchased for $100 or less will come with a 90 day no question warranty on everything. Bikes costing more than $100 will have a one-year warranty. You’ll be able to test ride the bike you are considering in a safe area behind the store (bring your favorite Helmet) and will be advised/helped out by one of our grade school/teenage mechanics - all who are real good at serving up a great bike buying experience! Ps: feel free to tip our young business people!
