BXT currently accepts PayPal payments only.

All payments are securely processed through PayPal. We do not store your payment information on our website.

BXT provides after-sales support for carbon frames, framesets and complete bikes.

Each order is checked before shipping, including the frame surface, fork, seatpost, headset parts and included accessories. If you receive damaged goods, missing parts or a product issue caused by manufacturing, please contact us within 7 days after delivery with photos or videos.

Our support team can also help confirm frame size, groupset compatibility, bottom bracket type, brake mount, headset specification and tire clearance before you place an order.

Choosing the right size is important for comfort, handling and riding efficiency. If you are not sure which size to choose, please send us your height, inseam, riding style and current bike size. We can help recommend a suitable frame size.

Please also confirm component compatibility before ordering, including groupset type, bottom bracket standard, crankset, wheelset, thru-axle size, brake rotor size, tire clearance and electronic/mechanical shifting setup.

If you are planning a custom build, contact us before purchase so we can help reduce compatibility mistakes.

Most carbon frames are produced or finished after the order is confirmed. Standard production time is usually 15–25 days, depending on frame model, size, color and current production schedule.

Custom paint requires additional time. Chameleon paint, ice-crack finish, gradient colors, pearl colors and special logo designs may take longer because they require more painting and quality-check steps.

Custom paint may slightly increase frame weight compared with matte black or standard finishes. If your main goal is lightweight performance, we recommend choosing matte black.

For custom colors, please provide a Pantone color code or clear reference images. We will confirm the design details with you before production.
