For sand, snow, and moon rocks.

El Oso Nino is Diamondback's smallest fat bike, made for kids who want to monster-truck over everything in their path. Four-inch wide tires sit atop 20-inch wheels, making for a unique style and ride. Low tire pressure allows the bike to grab every bit of traction available, with extra float for soft surfaces and sand. This little bear’s frame and fork are made from high-tensile steel, tough enough for prowling the neighborhood and the woods. It’s got a seven-speed Shimano grip shifter to charge up hills, and powerful disc brakes for control, allowing riders to go wherever the trail or their imagination takes them — maybe even to the moon!

This model fits riders 44”-55” tall, aged approximately 4-9 years old.

• Apex mechanical disc brakes with 160mm rotors front and rear provide great stopping power.
• Shimano Tourney 1x7 speed drivetrain with Tourney Grip Shift has seven speeds to keep shifting simple and easy to master.
• Durable frame constructed of Hi-Ten steel for a smooth ride quality.

RETURNS & EXCHANGES

Our "Ride Happy" Guarantee: We want you to love your purchase, but if you are not completely satisfied, we offer hassle-free returns on all orders.

You have 30 days from receiving your order to initiate your return with us:

• Returns must be in NEW condition with original packaging and product tags.
• You are responsible for packaging and return shipping. You may purchase a return shipping label from us, which is likely your least expensive option with our discounted rates.
• Regarding bikes, please take it for a "test ride" to make sure it's right for your Rider! Our standard for still being in new condition after a "test ride" is similar to a local bike shop offering test rides outside its shop. We understand some "dust on the tires," but please keep it new (and hold on to packaging) until you are sure you're keeping it!
• Your original shipping cost is non-refundable.

If you'd like to return your order, please start here.
