"Hi Jim, thanks for your concern. But we do not recommend frequently disassembling the City Vanture. The assembled frame has minimal symmetry deviation and brings a very balanced and smooth riding experience. You can even let your hands off the handlebars when riding, which greatly improves safety."

"Hi Joshua! Thanks for your attention. The assembled frame is the first step in our research on electric bicycles. We will continue to update the technology to create the next best bicycle. Vanpowers Bike is always working hard to develop bikes with excellent riding experience and safety."

"Hi Chris! Thanks for your attention! We believe assembling brings fun and a more balanced and safer riding experience. :)"

"Hi Eric, each screw has a corresponding required torque value, and the frame with the screws in place is hard to steal. We are currently in the research and development of the motor lock and fingerprint lock, we also sell anti-theft accessories on the website: https://vanpowers.bike/collections/accessories"

"The center deviation of the entire City Vanture frame is less than 1mm. For details, please refer to this picture: https://img-va.myshopline.com/image/store/2000465267/1644913950454/7273d6a2bf094c2daf3fe7f20a3cc42b.gif?w=695&h=391The racing bike frame has a center deviation of 0.2mm, and the higher-end bike frame has 1mm. The City Vanture's frame deviation of less than 1mm is already superior to high-end bikes."

"Hi William! City Vanture is our first assembled city road bike for commuters, we want to bring a smoother and faster riding experience for city commuters. We will continue to work to build the next best electric bike. Thanks for your concern. "

"Hi ba ken! City Vanture is not heavy in an equivalent aluminum frame, weighing only 34 lbs (15.5 kg) and can be lifted easily. The minimal center deviation is comparable to that of a road racing bike, and the riding experience is excellent. You can even let go of your hands off the handlebars.

"Hi Derek! Thanks for paying attention to the material of City Vanture. Vanpowers Bike is considering using carbon fiber material in the next e-bike. We've always been working for the next best electric bicycle.Our manual details how much torque is required for each bolt part. You can bring your torque wrench to adjust accordingly. :)"

"Hi Anders, people tend to overlook the symmetrical deviation problem of the frame. As a result, the unstable frame affects the riding experience and riding safety. City Vanture's superior riding experience of the assembled frame can be known by riding it. Thanks for your concern :)"

"Hi Steve! City Vanture frame has special high-strengtj screws and lock nuts. The screws are made of carbon steel with a strength of 12.9 and are 2 mm longer than those on the market. Other parts are made of 8.8 stainless steel bolts. The screws at each position have corresponding torque value requirements to enhance the stability of the frame. City Vanture's manual will specify how much torque is required for each screw."

"Hi Alan! We have detailed how much torque is required for each part of the screw in the manual. The screws at each position have corresponding torque requirements to enhance the stability of the frame. Thanks for your concern."
