Summary of Reviews

We have read all expert and user reviews on this bike. In summary, this is what cyclists think.

5 reasons to buy

  • The El Oso Niño is one of the lowest-priced children's fatbikes.
  • Families found this fatty rolled well on beach-sand, snow and trails.
  • One expert said his son’s confidence increased due to fat-tire stability.
  • The Oso Niño’s standover height was just right for little ones.
  • A Dad found the 7-speed drivetrain offered a good gear range.

2 reasons not to buy

  • At 35lbs for a kids’ bike, this fatty was Oso heavy!
  • There were derailleur issues; being sucked into the back wheel, breaking after one small fall, bending easily.

Bottom line

When the El Oso Niño was released, there were very few options for a kids’ fatbike. As is the case with adult fatties, there tends to be a big gap between low-end and high-end options. Fatbikes are expensive to build. As a consequence, the budget Niño, while being a “big step-up from a Walmart Mongoose” (one parent’s words), does come with some compromises. It’s weighty. At 35lbs, it’s heavier than many adult bikes. Also, the weak rear derailleur was itching to be replaced. These flaws aside, the added confidence (through extra stability and traction) meant that the Niño could train tots up to go mountain biking with the big kids.

I think the El Oso increased his confidence, as the tires and traction increased his stability.

Diamondback El Oso Niño

Level 1 expert

The low standover and 7 speed gear ratio have been great so far… Although the Specialized looks like it has higher end parts I just could not justify the added $300… There is a weight penalty and a lower part spec.
