Happy Board Co. - Modulus

The Modulus's simplistic concave style differs from all other concave designs by Happy Board Co. to give you an empty canvas to create your own custom downhill/freeride deck. Experience the full potential of the Modulus by customizing the concave with various implants and concave modules available as open-source 3d printable objects or with readily available items such as foot-stops and torque-blocks. Swap the modules with Velcro or attach the module you like with 3M double sided tape.

Customs duties & import taxes (orders outside the EU)

• Orders shipped outside the European Union may be subject to import duties, taxes and/or customs handling fees charged by your country's customs authority. These charges are determined by your destination country and are the responsibility of the recipient unless stated otherwise below.
• United Kingdom: orders over £135 (about €155,-) are subject to UK import VAT (20%) and may incur additional duties or handling fees on delivery. Orders of £135 or under have UK VAT (20%) included at checkout. Note: the UK has announced plans to phase out this £135 threshold by 2029, so this may change.
• United States: as of August 2025, the US no longer offers a duty-free allowance for low-value imports — all orders shipped to the US may be subject to customs duties and fees, regardless of order value. These are charged by US customs at the border and are not included in our checkout price.
• All other non-EU destinations: please check your local customs authority for applicable thresholds and rates, as these vary by country and are updated periodically by local governments. We are not able to predict or cover these charges on your behalf.
• We are not responsible for customs delays or charges, and we cannot mark orders as gifts or under-declare value to avoid them.

• We have a 30-day return policy, which means you have 30 days after receiving your item to request a return.
• To be eligible for a return, your item must be in the same condition that you received it, unworn or unused, with tags, and in its original packaging. You’ll also need the receipt or proof of purchase.
• Damages and issues: Please inspect your order upon reception and contact us immediately if the item is defective, damaged or if you receive the wrong item, so that we can evaluate the issue and make it right.
• Exceptions / non-returnable items: Certain types of items cannot be returned, like custom products (such as complete/mounted skateboards or longboards, griptape cut to a predefined length). Please get in touch if you have questions or concerns about your specific item.
• We cannot accept returns on sale items or gift cards.
• Exchanges: The fastest way to ensure you get what you want is to return the item you have, and once the return is accepted, make a separate purchase for the new item.
• Refunds: We will notify you once we’ve received and inspected your return, and let you know if the refund was approved or not. If approved, you’ll be automatically refunded on your original payment method. Please note it can take some time for your bank or credit card company to process
