My dealings with Tredz have been some of the worst I've ever experienced. I bought a bike from them and, when it arrived, it already had some cosmetic damage to the front fork. The setup of the bike must have been wrong because on my first or second ride the chain came off as I was shifting into a high gear. Later, after using the bike fewer than 10 times, some kind of issue with the gears caused the teeth on the middle chain ring to bend, which resulted in a gauge in the frame and an unusable bike. What made this whole experience go from frustating to infuriating is that, when I brought the issue to Tredz, not only did they refuse to accept any resposibility for the setup of the bike, they also refused to acknoledge my account of what happened. They insisted on telling me what actually happened. They didn't initially call me a liar, though the implication was there, but in my final phone call with them, I was flat out told that the person didn't believe me. The Tredz team's idea of a good deal was to offer me a marginally discounted replacement - not like-for-like - of the chain set. No mention of addressing the damage to the frame. The idea that I would spend any more money with this company is ludicrous. Avoid! Avoid! Avoid!
