When you buy a bike from Aventuron, not only will your bike ship for free, but you will receive a bike that is ready to ride out of the box.

We assemble and tune your bike, then repackage it to ship. When you receive your new bike it will be very easy to assemble. You will have to attach the front wheel, handlebar, seatpost and pedals. Most bikes do not include pedals, but we have an extensive pedal selection. We are a family-owned and operated business and look forward to having you as a customer.
