Bought a DCO Liberty e bike, 2 years ago and had to replace the rear wheel motor the first year. In second year the spokes in same rear wheel began to break and all had to be replaced. DCO did replace the defective motor wheel but not the broken spokes nor repairs. I only cycle in quiet city and no mountain biking ever. Bike s OK for the price, but service from DCO very questionable. Did anyone else have problems with any e bike from DCO? Thank you. Guy B
