I've ordered a bike for pickup. Will it be assembled?

Absolutely! We take care of all the assembly work for you. Our experienced mechanics ensure that every bike is fully assembled and goes through a safety check before it's ready for you to collect. So, if you'd like, you can even ride it home from the shop right away!

Just a small note: a few bikes might not come with pedals included, so you might need to buy those separately. If you have any doubts or questions, feel free to ask us!

When will I get my order?

We strive to process and dispatch parts orders promptly. If we receive your order by 12 pm from Monday to Friday, we aim to have it shipped out on the same day. However, during peak sales or exceptionally busy periods, there might be delays.

Once your order is on its way, you will receive tracking information from our carriers, which will allow you to monitor the delivery progress.

For more specific estimated delivery times, we recommend visiting our carrier's website.

If you need further information or have specific shipping inquiries, please refer to our Shipping Policy or get in touch with our customer support team for additional details.

Can you ship a bike to me?

Certainly! We offer bike shipping directly to your home. When your bike arrives, it will come fully assembled, although some basic mechanical skills and tools may be needed for the final adjustments.

If you're unsure about assembling the bike yourself, we highly recommend seeking assistance from a local bicycle mechanic. Please note that if you choose to have a third party assemble or inspect your bike, any additional fees incurred will be at your own expense.

Our goal is to ensure that you receive your bike in the best condition possible, and we're here to support you throughout the process. If you have any questions or concerns about the shipping or assembly, please don't hesitate to reach out to us.

Can you post overseas?

We're sorry, but we are unable to ship our products overseas. Our shipping services are limited to within our own country, and we do not facilitate shipments to international destinations.
