Terrible build quality followed by terrible customer service. Do not buy a bike from Tredz. Bike purchased in April 2020. Arrived in a state that would have warranted a full service from a qualified mechanic. Also had manufacturer defects. The customer service since has been truly appalling. Over an hour to wait to speak to anyone, none of whom know what is going on and have a complete inability to deal with complaints. Now mid June and no refund despite the product being defective and the product being rejected under Section 20 of the Consumer Rights Act 2015. Avoid this company.
