We like to make things simple here at Billy Bilsland Cycles, so our shipping services are crystal clear.

If you require expedited/next day shipping, give us a call on 0141 552 0841 or drop us an email on and we'll do our best to accommodate.

Every bike we sell is fully assembled and tested for safety by our trained mechanics. We then partly disassemble the bike and carefully re-pack to prepare for shipping.

Depending on the model, upon receipt you may be required to straighten and tighten the handlebars, reattach front wheel and attach the pedals. Please ensure that the pedals are greased and fitted correctly - the pedals will be marked L and R and have to be fitted to the left and right cranks respectively. Pedal do not come with every bike and need to be bough separately, especially on more high-end models. Please check when you are ordering.

There is a guide in the box telling you which tools you will need and the steps to follow. This will require some degree of mechanical skill to put together and can need some minor adjustments. The less confident you are in this field the more we'd recommend having it checked over by a professional mechanic.
