We pack a whole bike as simply and safely as possible.
The front wheel is removed and the handlebars are unscrewed and packed beside the frame with plenty of packaging and bubblewrap everywhere. The seat and seat post are also removed. On receipt you will need to re-attach the handlebars, put the front wheel back on and re-insert seat and post . It’s a simple job with an allen key but if in doubt your local bike shop should do this for a small charge.
