Why do you think that? Several components on that zip cast a huge shadow over the echo lite full build. Don't get me wrong, The Echo lite is a nice bike, but headset, brakes, B/B, cranks , freewheel, pedals are all of a lower standard then the Zip which is around the same price. Plus extras like the brake booster and brake clamps. Not trying to argue, was just a bit taken back by your statement. Cheers
