I bought a giant stance e-bike November 22. Upon receiving the bike I set up handlebars, fitted the pedals and took it out to try. The gears were jumping in various gears and during the first couple of weeks the bike was switching off whilst riding. I reported the problems to tredz and I took the bike to local bike shop which told me the chain and cassette needed replaced which I paid for as I needed the bike for work. The bike went to my local giant dealer for battery update. I got the bike back and again it started jumping gears and I got my local bike shop to check and was told it must be freehub, I contacted tredz again and was told to take to local giant dealer who fitted new freehub and told me that there was nothing wrong with the old one. I was told it needed a new chain and cassette again. Tredz asked me to return bike to them which I did and was told it was the way I was riding the bike. At this point the bike had done roughly 250-300 miles total from new. I refused to accept bike back and have involved trading standards and financial ombudsman. A week ago tredz and myself agreed that I would accept the bike back from them with new chain and cassette fitted at their expense and if it started playing up again within 30 days, they would take it back again for inspection. I received the bike back this week and the frame is covered in damage which tredz claim was because the bike was poorly packaged when sent back. I sent the bike with the front wheel off but wrapped in padded wrapping and secured so not to move. Tredz say there is no claim against themselves or DHL as it was poorly packaged. I asked them for the photograph evidence of this but they say they have none. If anyone is thinking of using tredz to purchase anything (PLEASE READ THESE REVIEWS BEFORE HAND) I am now sat with a £3500 bike covered in damage and to top it off, when I tested the new chain and cassette, it is still not right.
