Nationally Shipped Mountain Bikes

99 Bikes offers a range of mountain bikes available for delivery across the country, including both hardtail and dual suspension mountain bikes. We offer mountain bikes of all riding types; from Cross Country and Trail bikes, to Enduro All-Mountain Bikes and Downhill Mountain Bikes. Whether you are a casual weekend rider or a seasoned shredder, there are options suited to different ability levels and terrain types.

Start by thinking about the terrain you will ride most often and your experience level. Cross Country Bikes offer speed and efficiency, Trail Bikes offer a sweet spot between efficiency and capability, Enduro and All Mountain Bikes offer longer suspension travel and tuned geometry for more aggressive off-road riding and Downhill Bikes offer extreme durability and stability for downhill descents.

Common mountain bike wheel sizes include 27.5 inch and 29 inch, each offering different handling characteristics. Larger wheels tend to roll over obstacles more easily and suit taller riders, while smaller wheels can feel more agile and responsive on tighter trails.

A hardtail mountain bike has front suspension only, making it lighter, lower maintenance, and generally more affordable. Full suspension bikes add rear suspension for improved comfort and control on rougher terrain, which suits more technical trails but comes at a higher price point.

Frame size has a significant impact on comfort and control, so it is important to check the sizing for each bike before purchasing. Try out our online sizing tool to provide the best guide on while sizes will work for you based on each bike's geometry, and the 99 Bikes customer help team can also assist with any sizing questions before you place your order.

Mountain bikes can be delivered to addresses across the country, so you can shop without needing to visit a store. Bikes are shipped partially assembled and will require some setup on arrival, so factor in whether you are comfortable with basic assembly or would prefer to have a local mechanic assist.

Finding the right bike size can feel tricky, as different bike types have slightly different geometries. To make it easier, we’ve created a Find Your Size tool. Simply enter your height and inseam measurements (or those of the person you’re shopping for), and we’ll recommend the best size for each bike and pre-select the recommended option for you.

Not sure of your inseam measurement? No worries! We provide an estimated inseam measurement based on your height to help keep your recommendation as accurate as possible.

You can find the tool on each product page or at the top of categories when browsing. Try Find Your Size.
