Effective Date: 08-10-2026 Last Updated: 08-10-2026 DOCUMENT VERSION: 002

These Terms of Service ("Terms") are an agreement between you and duke bikes LLC, doing business as duke bikes ("duke bikes," "we," "us," or "our"), governing your use of our automated bike rental stations, bicycles, website at dukebikes.co, and service platform at ride.dukebikes.co (together, the "Service").

By checking out a bike or otherwise using the Service, you agree to these Terms. If you do not agree, do not use the Service.

Eligibility

You must be at least 18 years old to check out a bike. A person under 18 cannot check out a bike for themselves. By using the Service, you represent that you are 18 or older, that the information you provide is accurate, and that you are able to enter into this agreement.

You are responsible for all activity under your checkout, including every rental you start and every bike you unlock. You may check out bikes for members of your group (your "Party") as described in these Terms; doing so does not transfer these obligations to them.

The Service

duke bikes operates automated, unattended bike rental stations ("duke bikes" and the "operator" mean the same entity throughout these Terms). You locate, unlock, ride, and return bikes using the Service without on-site staff. Because the stations are unattended and the bikes are used by the public, the condition of any bike can change between our maintenance checks.

We may modify, suspend, or discontinue all or any part of the Service — including pricing, station locations, bike availability, and features — at any time, with or without notice, except that changes to pricing apply only to rentals started after the change.

Rentals, Payment, and Fees

Rental charge. Rentals are charged at a per-hour rate for each bike rented. The per-hour rate is displayed to you at checkout before you start a rental. Your total rental charge is the per-hour rate multiplied by the number of hours (as calculated below) for each bike you rent.

Hourly rounding. Rental time is billed in whole-hour increments and rounds up to the next full hour. Any partial hour counts as a complete hour. For example, a rental lasting one hour and one minute is billed as two hours. By renting, you agree to this rounding method.

Pre-authorization hold. When you start a rental, we place a pre-authorization hold on your payment method through our payment processor, Stripe. The amount of the hold and the per-hour rental rate are displayed to you at checkout. The hold is placed at the time the rental starts.

Capture of the rental charge. At the end of the rental, under normal conditions, the rental charge (calculated as described above) is captured from the pre-authorization hold, and the remaining balance of the hold is released back to you. In a normal rental, you are charged only the rental charge, and the rest of the hold is released. You acknowledge that the operator may capture all or part of the pre-authorization hold at any time it deems appropriate.

Failure to return; charge for a taken bike. The operator determines, in its sole discretion, when a bike is considered taken and not returned within the proper time. If the operator determines that a bike has been taken, you may be charged immediately up to $2,000 per bike, an amount representing the replacement cost of the bike and its installed equipment together with the costs of recovery and administration. This charge may be satisfied in whole or in part by capturing and not releasing the pre-authorization hold described above, together with an additional charge to your payment method, up to the $2,000 per-bike maximum. This is a single charge triggered by the failure to return the bike, not an hourly or continuing charge. You agree to this term.

No transfer of ownership; continued pursuit. Being charged for a taken bike does not transfer ownership of the bike or bikes to you. The bike remains the property of duke bikes LLC at all times. Even after you have been charged, the operator may continue to pursue all available remedies, report the bike as stolen, and attempt to recover the bike or bikes. The charge is not a sale and does not release you from responsibility for the failure to return the bike.

Release of funds and technical issues. Under normal conditions, the unused portion of the pre-authorization hold is released at the end of your ride. In the event of a technical issue or rider error, the release may be delayed. If a technical issue affects your charge or hold, we will make our best effort to correct it and release your funds as soon as reasonably possible. You understand and agree that this can be a time-consuming process, that released funds may not appear immediately, and that additional time may be added by Stripe and by your own bank or card issuer, over which we have no control.

Charges final; your responsibility to report. Except as described above for technical issues, all charges are final and non-refundable, and any refund or credit is at the operator's sole discretion. It is your responsibility to review your charges and to contact us promptly at hello@dukebikes.co if you notice any error, unexpected charge, or issue with your billing. We cannot address problems we are not made aware of, and we will correct any charge we determine to be made in error.

Rider Requirements and Experience

The Service is intended only for people who already know how to ride a bicycle safely.

By renting a bike, you represent and agree that:

You are an experienced bicycle rider, physically fit to ride, and familiar with the operation of a bicycle, including braking and shifting;

Every person who rides a bike you check out — including any minor or other member of your Party — is likewise an experienced rider, physically able to ride safely, and capable of understanding the rules of riding;

The Service does not provide riding instruction, supervision, or safety equipment, and you will not permit anyone who lacks riding experience or ability to use a bike you check out.

Bike Inspection — Your Responsibility Before Every Ride

You must inspect each bike before riding it. At a minimum, before each ride you (and each member of your Party, for their own bike) must check: tires and wheels, brakes, seat and seat post, handlebars and stem, pedals, and the frame, and confirm everything is secure and functioning.

If anything appears damaged, loose, worn, or unsafe — do not ride the bike. Return it to the stall, report the problem to us at hello@dukebikes.co, and select a different bike. By beginning a ride, you confirm that you inspected the bike and found it in safe working condition. If a problem arises during a ride, stop riding the bike as soon as it is safe to do so and report it.

Obey the Law

You must obey all applicable local and governing laws while using the Service.

Helmets and Safety Equipment

Do not ride without a helmet. We do not provide helmets or other protective equipment. You must ensure that you, any minor in your Party, and every other rider under your checkout wears a properly fitted helmet, and any other legally required protective gear, at all times while riding.

Your Party

If you allow any other person, including any minor, to ride a bike you check out:

You must explain these Terms to them first — including the bike inspection requirement, the requirement to obey the law, and the helmet requirement — before they ride;

Each of them should be an experienced, capable rider;

You are responsible for the bikes you check out and for their proper return, and for any property damage caused during their use;

A person under 18 cannot check out a bike themselves and may ride only as a member of your Party, under your supervision.

Prohibited Conduct

You and your Party must not: ride under the influence of alcohol or drugs; ride at night, during twilight, or in any conditions of reduced visibility — all bikes must be returned to a station before twilight begins. Our bikes are not equipped with lights, and riding them after dark is unsafe and may violate the lighting requirements of applicable law; carry passengers on a bike not designed for them; use a bike for racing, stunt riding, towing, or commercial delivery; exceed the manufacturer's stated weight capacity of 350 lbs (including the rider and all cargo) or any lower capacity posted on a particular bike — it is your responsibility to confirm before riding that the bike is suitable for the rider and any cargo; tamper with, modify, or attempt to repair a bike or station; abandon a bike outside a designated station; or use the Service in any unlawful manner. Violations may result in immediate termination of your access, forfeiture of fees paid, and responsibility for resulting damage.

Conditions, Weather, and Returning Before Dark

You are responsible for deciding whether road, traffic, lighting, and weather conditions are safe before and during each ride. Bikes are not equipped with lights and must be returned to a station by sundown; riding at night is prohibited as described above under Prohibited Conduct. Plan your rental so you can return the bike before dark. You should not ride in conditions you are not equipped or able to handle safely.

Lost, Stolen, and Damaged Bikes

You are responsible for the bike from the moment you start a rental until it is properly returned to and secured at a designated station. You are responsible for the bike's safekeeping during your rental, and you must not leave it unattended in a manner that invites theft or damage. You agree to pay for loss of or damage to a bike that occurs during your rental, beyond normal wear, up to the $2,000 per-bike maximum described above under Rentals, Payment, and Fees; a bike that is lost, stolen, or not returned is governed by the "Failure to return" provisions described there, including the no-transfer-of-ownership terms. Properly returning a bike to a designated station and confirming the return in the Service ends your responsibility for that rental, except for damage occurring during the rental.

Electronic Communications and Consent

By providing your email address and phone number, you consent to receive service-related communications from us electronically, including by email and text message, and you agree that electronic agreements, notices, and records satisfy any legal requirement that such communications be in writing. Standard message and data rates may apply to text messages.

Acceptance records. You agree that your electronic acceptance of these Terms — including clicking "agree," submitting your details, or initiating a rental — constitutes a valid, binding signature and agreement under applicable electronic signature laws, and that our records of the date, time, and manner of your acceptance, and of the version of the Terms in effect at that time, are admissible and presumptively accurate evidence of your agreement.

Privacy

Our collection and use of personal information is described in our Privacy Policy at dukebikes.co/privacy-policy, which is incorporated into these Terms.

Changes to These Terms

We may update these Terms from time to time. When we do, we will revise the "Last Updated" date above and, for material changes, provide notice on the Site or by email. Your continued use of the Service after changes take effect means you accept the updated Terms.
