OK you guys have me thinking about these chains. On this site theres about 20 bikes to look at fully assembled...... SANTA CRUZ GREEN MOTORS-COMPLETE ASSEMBLED MOTORIZED BICYCLE-LINKS
....Im going to assume whoever is doing the assembling knows what theyre doing. On some of the bikes the chain looks nice and tight and on others the chain looks like it has 3 inches of play in it. Why do the ones that are loose have so much play? Is it necessary? I could see on a full suspension bike but not these because there might be a need for it. Length cant be the issue because some are loose and others nice and tight.
