Notes on complete bike purchases:
  1. Some assembly required. It is advised that a professional mechanic perform the assembly. It is at our discretion which warranty claims are due to improper assembly versus actual defects, and no warranty claims will be accepted unless it is proven that a professional mechanic performed the assembly. Please refer to the attached video on what you may need to do to assemble the bike.
  2. Only the size we photographed and assembled will have its weight provided.
  3. No sizing information will be provided beyond what’s written above. We'd prefer to only open one size of each model. I'm sure as a customer, you'd not wish to have your bike box opened, unwrapped, and disturbed. So, anything that would differ from size to size, like crank length, stem length, weight, and images, will not be provided. Assume that the manufacturer provided the lengths that made sense given the size of the bike.
  4. We cannot determine proper sizing given your body. It’s a personal choice as to which size you prefer, and there are loads of resources online for you to best choose a size that fits your body. We advise you to stay away from resources regarding standover height as a method of determining size.
  5. We will not warranty any crank issue due to improper assembly. Failure to sufficiently tighten crank bolts, pedals, or putting the wrong pedal in the wrong crank arm (there are right and left pedals), will not be warrantied. 
  6. The manufacturer may have made equal, but different subsitutions on the bike such as tire brand, stem length, crank length, etc. We cannot open all the boxes, unwrap them from their protective packaging, and verify that every single bike is exactly the same as the bike we used for images and this components list. It is highly probable that your bike will be identical, but if it happens that not everything is exactly the same and all parts are equivalent in quality, we will not offer any compensation for the parts to be replaced.
