The Cannondale has a very stupid battery position, which is going to catch every bit of crud and crap going.
The Centurion has poor suspension linkage design, that leaves two bolt heads impossible to check as part of regular maintenance.
The Trek Powerfly, has cables poorly routed, and are likely to snag up on the first bit of under growth.
The Lapierre looks as though the design team misunderstood the design brief and opted to keep the dustbin, and threw away the bike. 10 out of 10 for the worst looking bike ever.
